Roberto Katze (ロベルト=カッツェ Roberuto Kattse?) is a side character introduced in Shinyaku Toaru Majutsu no Index. A man prone to scandals, he is a well-meaning man who loves his country. He is the current President of the United States of America in the world of Toaru Majutsu no Index.


A large man with a muscular physique, he has swarthy-skinned due to the fact that he is Hispanic. His most prominent feature is his swept hair and accompanying his thick chin curtain beard.


Unusual for a President, Roberto shows familiarity and openness to people nearly to the point of childishness; he is apparently really sensitive about the fact on how people do not recognize that he is the U.S president when they meet him in person, despite his frequent media appearances, and was often hurt about the fact that some had accused him of being an impersonator when he was in Hawaii. Although, his appearance says otherwise, he shows an intelligence uniquely his own.[1]

Along with this, Roberto has the propensity to embellish the truth for his own gain. An example of this is when he exaggerates his father's apparent many deaths.[2] He is a playboy and is rather perverted, having an erection even in front of world leaders[3] and during public speech.[4]

Roberto is apparently familiar with Japanese pop culture, as he is aware of terms such as "tsundere", which is something that has rubbed off his aid, Roseline Krackhart, who is aware of the meaning of such terminology.[5][6]


He was an undocumented immigrant who crossed the Mexican border. From there, he learned to read and do math and then he successfully modified the election laws.[4] He is the third Hispanic President of the United States, and the first President to be a high school dropout.[1] His campaign was apparently backed up by Olay Blueshake, the queen of media.[7] With his personality as well as his "verbal slips" on political matters, he is referred to a strange politician; because of this, his approval ratings do rather well from them, because the electorate feels more of a connection.[8][9]

He is still single, although he has a fiancée that he has already proposed marriage to.[1]

Shirai Kuroko as Roberto Katze

In the anime series, though he didn't make a physical appearance, while in the form of Shirai Kuroko, Roberto made an appearance in a press conference due to one of his many political scandals. His only speaking line was "Yes, we can." Roberto's broadcast appearance, as Shirai Kuroko, made Touma realize that his family, friends, and acquaintances weren't setting up a prank on him and a form of magic had made them change their outer appearance.[10]

Hawaii Invasion Arc[]

Main article: Hawaii Invasion Arc

He debuts in the third volume of Shinyaku Toaru Majutsu no Index, showing his ability with the media, regarding the aftermath of World War III. He later escapes his own security forces, aware of a strange malaise that seemingly makes previous normal people turn against America, even within the core of his government, and decides to investigate on his own. His disappearance later leads his aide, Roseline Krackhart, to find him, who is also aware of the suspicious people in government.

Meanwhile, Roberto uses the Imperial Package to track the movements of suspicious persons, and discover a threat that could take the lives of thousands of people. He is later attacked by one of the persons who have their loved ones being controlled by Saronia Irivika of GREMLIN, but is able to subdue him using his negotiating prowess. Hither, he discovers that the only thing that all the controlled people have in common are the look in their eyes, a blank and spiritless gaze. Roberto discovers that the person who attacked him is not one of those people are directly controlled, and as such is determined to use him to get behind the controller's defenses. Roberto later arrives at the Coral Street Shopping Mall, just in time to save Accelerator from GREMLIN magicians, after Accelerator accidentally used magic. He later takes Accelerator away from the chaos, where they converse about the situation regarding GREMLIN's influence in the United States. He later divulges to Accelerator about the Trigger who then reports it back to Kamijou Touma and company, regarding GREMLIN's plans to use it to erupt a volcano.

With things calming down, Roberto takes Touma, Accelerator, Misaka Mikoto, and Leivinia Birdway to Pearl Harbor, where the Trigger supposedly resides. With Leivinia's suggestions, they simply walk into the base and orders the grunt working (Nike Canox) there, knowing that Saronia would only require to control higher ups, this is confirmed when a military officer (Bax Silver) enters the based and complicates Saronia's plans. Later, with Touma and Mikoto, Roberto checks one of the cargo planes, wherein they discover Saronia herself. Here, Roberto is given protection by Mikoto, as Touma does battle with Saronia with back up from Mikoto. Eventually, after Mikoto destroys several of the containers, Saronia discovers that Trigger isn't here, shoots the pilot and parachutes out of the plane. After checking up on the pilot's condition, Roberto, Touma, and Mikoto states to the pilot that they would leave him behind, and would require him to make an emergency landing instead of crashing the plane. They are rescued just in time by Arc Daniels to see the eruption of Kileau, though they realized it is much more downplayed than they expected. They later realize that the use of Trigger for the eruption as well as the Narwhal anti-ship missiles used to attack their company after being rescued was used to isolate the entirety of Hawaiian Islands for a much bigger purpose.[11]

While resting during the Fall of Pearl Harbor, Roberto discusses with Touma, on how he suspects that many of the people working for Saronia and part of his government may not actually be controlled by magic by Saronia at all. Sowing the seeds of doubt on Touma's mind, as he rethinks Birdway, Cendrillon and Saronia's actions. Roberto then speculates that Saronia's true power may not be mind control at all. Roberto further states that the mercenaries that GREMLIN hired for the invasion of Hawaii maybe Trident, due to the technology used, and is one of the largest privatized military corporations in the world. After using the Imperial Package, Roberto states that the most likely person who has assets outside of the United States that could hire an army such as Trident would be the media queen, Olay Blueshake.[7]

In a phone conference with the rest of Leivinia and Touma's group, he discusses Free Compound Eyes, a supposedly defunct free camera service which can be accessed by the search engines owned by Olay, maybe used to monitor their actions. Roberto further provides evidence to Olay's involvement by stating that Olay is as powerful as an entire house in Congress. Roberto continues his explanation that Olay tried to get herself elected but due to the onset of the Third World War, was unable to direct the country to the ways she wanted, and maybe the reason why she contacted with GREMLIN and Trident. Roberto states that she cannot be arrested as her current whereabouts are unknown. He later learns that Roseline has begun her move against Olay by gathering troops in order to make Olay's daughter, Lindy Blueshake, as a bargaining chip against her, with the variable that the troops may kill her. With Touma's determination, Roberto agrees to get to Lindy first before Roseline.[7]

Roberto accompanies the entire Leivinia Company, and uses the Imperial Package to find Lindy's current whereabouts. He is later part of the team for Lindy's rescue along with Shiage and Leivinia. They are later delayed as Roseline's troops are in a military engagement with Trident troops, leading with the latter's decimation and allowed Roseline's troops to take control of one of the northeastern beaches in Kauai, allowing them to search for Lindy in earnest. They later arrive at Lindy's residence which was in the process of being overtaken by Trident, however, Roberto managed to successfully collect Lindy at the cost of her manservant, where Roberto states that he will be much safer if he was not with Lindy. Mikoto later rendezvous with them, whither Roberto gives Mikoto advice to woo Touma, after she haphazardly mentions mentioning giving a gift, much to her consternation. She later tries to stop a tank while Roberto and company brace themselves from Cutter bullets, figuring out it may be members of his country’s military attacking them. With their transportation wrecked, Roberto and Shiage are dragged off, while they take Lindy by marines. Although one of the marines were hostile and tried to attack Roberto, the large part of the unit led by Corporal Martin Flowers were allied with Roberto. He later calls Roseline to tell her to lay off her search for Lindy in order to use her against Olay, and states that they need only to subdue Trident's commander in order to stop Trident. Roberto arrives along with Roseline to confront the commander, Cinesic Evers, and forces him to back down his forces, threatening the future of Trident and allies attacking the United States with a threat of being slaughtered by them. However, Cinesic does not acquiesce and instead orders all his troops to converge in Napali Coast and support Saronia. Later, after Saronia is defeated by Touma, Roberto once again tells Cinesic of terms of his surrender, lest they face a more brutal punishment, which the latter agrees to.[12]

Roberto later returns to a hotel along with everyone, reporting on the missing GREMLIN operatives in Trident uniforms. Roberto later laments on Olay still being uncaptured, however, he uses this opportunity of her being missing to transfer all of her company’s assets to Lindy, her daughter, putting Olay in a tough spot, without allies and without money.[13]

GREMLIN invasion of Tokyo[]
Main article: GREMLIN invasion of Tokyo

Noting the destruction and violence GREMLIN has wrought, not only in Hawaii, Roberto Katze has calls together many different nations and powers to prepare for a unified attack on GREMLIN.[14] Roberto is with Roseline Krackhart in New York City, after calling forth the leaders that of the countries that have been affected by GREMLIN's reign of terror. Here, they talk on the streets near the United Nations building, knowing that people will surely think they are joking as they talk of states secrets casually out on the open. Roberto asks why they couldn't use the White House since it would've been much safer, to which Roseline states that the residence of the President has too much political pressure, and that those that do not want the United States leading the solution to their debacle might not want to gather there. Moreover, she is bothered by the journalists there, and sees that it will be easier if the meeting be done in New York. Roberto mentions that New York is also filled with journalists, to which Roseline states that they are merely paparazzi. Roberto mentions an emergency financial meeting of the G14, to which Roseline says that they interfered with the stock market, to prevent the gathering of the heads of state from looking unnatural.[3]

Then, Elizard just arrived with her bodyguard Kanzaki Kaori, arousing Roberto, who says that he wants Elizard to tell him where she hired Kanzaki as he wants to add some beauty to his security team. There, Elizard tells him that she is a Saint despite her appearance, though Roberto already knows this and wishe he already has one, much to Roseline's chagrin. Kanzaki herself grimaces at the scene.[3]

Then, the Russian Orthodox Church representatives arrive, Russian Orthodox Church Patriarch Krans R. Tsarskiy, Vasilisa, and Sasha Kreutzev. The latter are arguing about Vasilisa having "faith" in something other than "Japanimation" and American culture, despite being a member of the Russian Orthodox Church. Sasha then says that Vasilisa should be afraid of falling victim to an inquisition for saying such things in front of the Patriarch. Krans hears this and says that he wouldn’t do it. Roberto then asks where there others are while reading a lewd magazine in front of the others. Roseline says that the French are already inside the United Nations building, the Roman Catholic representatives should arrive shortly along with the Italian Foreign Minister. Thus the meeting of the Anti-GREMLIN Alliance draw near.[3]

Roberto complains about not being able to contact Aleister Crowley of Academy City, despite knowing that the City might take the leadership of the attack on GREMLIN from the United States. However, Roberto is disturbed by the City's lack of cooperation, as it would mean that they might take their own actions against GREMLIN and would likely hinder the Alliance as well. Roberto tells them to enter the United Nations building, but is told by Roseline to close his lewd magazine and stop his erection. Roberto jokes that she could always take care of it for her, annoying Roseline to the point of hitting him on the back with her heel, much to the present Secret Service personnel's shock. Roseline's anger later forced the representatives into the building, including Roberto. Here, he asks about the "illegals" (like Leivinia Birdway) taking part in the meeting, to which Roseline says that they cannot enter the building but will be connected by a line that will leave no records, taking part with the meeting in real time from the other side of the globe. Here, he muses about what kind of persons they are if they are able to stand on the same levels as a representative of an entire nation.[3]

A meeting of leaders.

They are in a small conference room as they discuss the events related to GREMLIN that have transpired.[15] After everyone has been briefed on the fantastical topics of the current situation of GREMLIN, the lance of Gungnir, and Sargasso, Roseline speaks to summarize and clarify what they just discussed.[16]

Elizard says that she is correct and that the information comes from a spy in GREMLIN. She then says that what matter most is the creation of the lance at Sargasso as it is very dangerous. Roberto doesn't understand and compares it to a nuclear weapon. After the other state heads take turns explaining the danger of the lance of Gungnir, Elizard says that it must be stop before it is finished. Roberto then asks how they will find it, noting the extremely difficulty of such a task in such a short timeframe. Elizard says that it is not impossible, surprising Roseline. Elizard not only gives an example but confides to them that England had a secret transportation network that allowed them to fill the entire world with their magicians. Elizard comments on the Roman Catholic Church and its countless followers, assuming that the Church may have a large scale magic to utilize each member of the Church who is wearing a symbol of their Church. Pope Pietro Yogdis says that he can think of a few but has shut them all down since the dissolution of God's Right and shall never see the light of day so long as he is around. And thus it is revealed that already know the location of Sargasso, apparently waiting for a proper deliberation from all the members of the conference before making a decision. Elizard suggests the use of standard forces comprising of America, Russia, England, and France, while the magical forces however, will be led by England, Rome, Russia, and France, though requiring other countries to double duty. Hearing this, Russia and France readily agreed.[16]

Elizard then asks President Roberto Katze on how much firepower they could use. Roberto answers that since the House of Representatives is still itching for revenge over the invasion of Hawaii, he can get immediate approval from them for an attack on Sargasso. Roberto states that he can officially use the military stationed at four overseas bases in allied nations and if Sargasso is in international waters or the territorial waters of America, the European Union, or any other allied nation, he can have ballistic missiles fired in the name of having a test launch. And though he cannot use any nuclear, biological, or chemical weapons, he can at least have them fill the warhead with bunker clusters. Concerns over straining of the relationships between the countries later arise after Roberto's politically dangerous suggestion, to which he concludes by saying that he'd rather have countries gaining grudges with each other for what they will do than have the world destroyed today. Krans R. Tsarskiy then asks where the Sargasso might be, to which Elizard states may be in the North Sea or the sea near Iceland.[16] And thus begins the Anti-GREMLIN Alliance attack on the North Sea Sargasso. After receiving word of the disastrous mission, the members do not have time to grief over their failure as immediately after they are forced to counter GREMLIN who has begun their move, an invasion of Tokyo.

The alliance have their work cut out for them as GREMLIN puts pressure on their enemies, distributing what people desired to gain in order to prevent their enemies to unite and defeat just like what happened against Fiamma of the Right during World War III. With this, the alliance could not launch a counteroffensive against GREMLIN quickly enough. Roberto chastises a Japanese representative over the phone, asking why they have yet to make a move against GREMLIN, demanding consent that the United States should intervene. After the representative doesn't give a satisfactory response, Roberto ends the call. Elizard says that he should've asked what Academy City intends to do, though Roberto doubts that they would've known anyway. Roseline says that the Japanese government is divided on the issue, and Academy City has made no announcement. She is amazed at GREMLIN for intentionally created this current balance of power. With the clock ticking and with the Japanese government neutered into focusing in moving their government elsewhere before taking action, Roberto deliberates on his choices. Pietro then says that Academy City will make their move soon, though he has doubts if Academy City will bother distinguishing between friend or foe. The Maiden of Versailles then says that she doubts that Academy City even completely trust them, conjecturing that they another magical group will try to attack them within the confusion caused by GREMLIN, something that is only favorable to GREMLIN itself. The Russian Orthodox Church Patriarch Krans reminds them that doubts and constraints are all part of GREMLIN's attempt to buy time, and that they need to have as many people they can at least trust. However, no one agrees with his assessment as there was no time. Roberto then asks Elizard if the Anglican Church have a hotline with Academy City, as they have joined forces during World War III. Elizard points out that it was the Anglican Church's doing and the British Royal Family was barely involved. Elizard then states that the Church as well wasn't able to contact Aleister since the end of the War. Out of allies, out of options, and out of time, Roberto contemplates what they should do. His stupor is later broken by Roseline, and there Roberto gave a small smile. He says that what they should do hasn't changed, and tells them that they should make a vote. One of the people there asks if they are using democratic decision to distribute responsibility, to which Roberto says that only those who go along with their plan will become responsible. Thus the alliance finally makes their move against GREMLIN.[14]

Shifting and Fluctuating World[]

In the first recreation of the world by Othinus, known as the Version_Alpha world in-text, where she has changed the entire perspective of the world to make Touma into the world's enemy and thus break his spirit, the alliance formed to combat her and GREMLIN in Touma's original world is an international coalition that is set out to kill Touma. When Touma first arrives through Othinus' powers, he discovers that Tokyo has been invaded by the coalition in order to eliminate him, ravaging Japan's capital greatly with 70% of its 23 special wards destroyed.[17]

As the invasion continues, Roberto Katze is seen by Touma in this world making a statement. Here, he says that the Japanese government may have admitted Touma is hiding in their country, but they have hid that fact for a long time. Roberto says that it is an insult to the people of all nations who wish for a stable and peaceful and international society. He continues by saying that even though they are putting great suffering of the people of Japan, they have no choice until they have definite and undeniable proof that Touma is dead, calling him a demon. Roberto then says that these actions will be vindicated by history as they cannot allow Touma to live any furthermore. Here his speech receives a warm applause from his audience. Touma can only watch in disbelief at this scene.[17]

VS The World[]

Unbeknownst to them, Othinus has already changed the world countless times and have reverted it back to the one Touma remembers. The magic members of the international coalition, the Anglican, Roman, and the Russian Churches later try to bombard Othinus with countless shooting star-like attacks. However, Touma, who have come to understood Othinus through the countless worlds that Othinus have subjected him, negates them and saves Othinus.[18]

Immediately after stopping the international coalition's magic attack on Othinus and declaring his intention on saving her even at the cost of making the world his enemy, Touma and Othinus spirits away from the group and vanish.[19]

President Roberto Katze, Queen Elizard, Pope Pietro Yogdis, Patriarch Krans R. Tsarskiy, and the Maiden of Versailles are still in the UN Headquarters when they hear the news. Roberto receives the information through the soldiers gathered there, UAVs, and military satellites, and is shown to be worried. Krans says upon hearing the news says that Touma's actions does not fit with his previous behavior. Roberto replies that Touma has had contact with GREMLIN a few times before. Krans references the events of Hawaii, Baggage City, as well as that in Academy City, and wonders that there may be a reason on how Othinus allowed Touma to live back in Baggage City even though she has absolute power. The Maiden of Versailles cuts in the conversation, saying that it not the issue as of the moment. Elizard adds that saying Touma is innocent because they know him isn't enough now as the doubts have begun adding up, and reiterates that the only way to stop the chaos surrounding the world is to attack and eliminate the source. Elizard explains that if they don't do it, human society will soon boil over with fear of Othinus. Despite Elizard's position, she, seeing Touma's power in action many time before, knows how painful it is to know that Touma is now their enemy.

Thus, the international coalition begins mobilizing for the manhunt for Othinus and Kamijou Touma, with the three major churches releasing the restrictions on specially sealed spells. As Elizard watches as her fellow representatives begin their preparations, she thinks that it might be better to leave the matter to "official" groups like the SAS and MI6, as she thinks extreme irregulars using supernatural power might actually give him a way out. Roberto sighs as the events unfold before his very eyes. Without much of a choice, he says that they can only continue as normal. He says that they will find the "Othinus faction" and destroy them as it is the only way to prevent society from growing any more unstable.[19]

With that, the coalition later somehow find that Touma and Othinus are in Denmark and direct their forces there. The Pope and Roman Catholic Church relieves Agnese Sanctis, Lucia, and Angelene of their positions as security for the meeting of the international coalition and have them and the rest of the Agnese Forces sent to Denmark. They are transported there by their ally the United States of America through the use of their stealth bombers, and are further bulked up by the inclusion of elites from the Russian and Anglican Church.[20] The Patriarch and the Russian Orthodox Church relieves Vasilisa and Sasha Kreutzev of their bodyguard duties for Krans and are sent to Denmark through unknown means, though it is likely they arrived with the Agnese Forces.[21]

The Queen despite her thinking that it would be better to use soldiers, later with the Anglican Church relieves Kanzaki Kaori of her bodyguard duty and has her rendezvous with Princess Carissa, William Orwell, and the Knight Leader on the Hotel Ariel just off their recent mission.[22] Likely with her blessing, she allows Index, Leivinia Birdway, and Lessar to go to Denmark as well, with Lessar in communication with their forces.[23] France also plans to mobilize their own forces as well.[24]

Finally, the President and the United States of America, not having any magicians with them, send out commandos to Denmark for Operation Norse Wind.[25] There, the coalition monitor the actions of their units from the New York.

Touma pleads for Othinus' life to President Roberto Katze.

After Ingrid Martin's team knocks out and captures Othinus and Touma, Roberto is contacted by them as Touma regains consciousness. Roberto tells Touma that though he doesn't know why he sided with Othinus, he should've at least known what would happen to him. Knowing that he can't bring up the President's debt to him for helping him back in Hawaii as Roberto is making his decisions with every citizen of the United States of America weighing on his back, Touma is aware that his chances of convincing Roberto is stacked against him. Regardless, Touma knows that he must win by giving Roberto and the rest of the United States of America a reason to hold off on killing Othinus. Touma asks Roberto that since he is even bothering talking to him then he must at least feel a little hesitant, to which Roberto says that he is only merely killing time until his soldiers have secured the video line which would allow him to see and confirm for himself how his soldiers will kill Othinus. Touma however says that he will not let him kill Othinus. Roberto then replies that Touma has 10 minutes to explain why he shouldn't if he can, though states that he has enough reasons for kill her as well. Despite Roberto's called words, he was willing to talk allowing Touma to believe he can reach him with his words.[25]

Touma tells him that he still doesn't know everything about Othinus, why she fled to Denmark, and that it would be bad if America eliminated her without knowing her objectives or motives. Roberto says that it doesn't matter if their reputation is damaged as the definite stability of the world is more important. He references that since Touma had been out on the field facing GREMLIN he should have a better grasp of what they are, though he says that the vast majority of the world doesn't know any of that, and because of that it may lead to rumors that will give GREMLIN a false credibility and a new war will break out of it. Hence the reason for nipping the problem in the bud by killing Othinus. Touma says that Roberto isn't wrong, but says that that's all the more reason why they can't kill her. Touma says that even if GREMLIN lost its head, Othinus, it will not disband the group, though the members would scatter randomly. Touma says that as they have lost their objective, in anger they will attack the peaceful world, and their first target would be America, the country that had led to that peaceful world. Roberto says that they are prepared for the fight to continue, and says that they are a country that will not forgive a villain in fear of a distant future. Touma says that American will not be hunting down remnants of a group as GREMLIN has already proven itself that a superpower like American can be brought to its knees as shown in Hawaii. He asks Roberto what would happen if the other members of GREMLIN gathered together, and references on how there are a lot of people who would like to defeat America. Roberto however points out that keeping Othinus around would lead to war just the same. Touma however doubts that, saying that to predict the behavior of the other members of GREMLIN, they need to know their secrets, and who has better knowledge of them than their leader. Touma adds that GREMLIN cannot name themselves a new representative as long as Othinus is alive, allowing them to hold off GREMLIN's reorganization and regrouping, and in turn allowing them to slow the spread of chaos that they bring along with them.[25]

Roberto however says that Othinus' power is unknown to them, drawing from his recent experience in Tokyo with the lance of Gungnir, he says that there is no good reason to let her go as she can do worse things in the future. Moreover, he says that they can't detain her somewhere as well as they cannot guarantee GREMLIN won't be able to attack and break her out. Hearing this, Touma draws out the key sentence for his argument: they need only to take her power from her. Touma says that he and Othinus is trying to permanently remove her power then surrender to them, removing the threat of a future where she can do even worse things, and essentially removing the reason to kill her. Hearing this, the President asks if there really is such a convenient way of doing so. Touma tells him that he and Othinus did not come all the way to Denmark without an objective in mind, and says that if they were truly running away then it'd be easier to hide out in some quite mountain. Without waiting for a reply, Touma says that they are not writing off Othinus' crimes, and says that once everything is settled, they can lock her away as lock as they go through the proper procedures and that they will not impede them if they do. Touma then asks if he still feels the need to kill her even though they are merely preparing her to be sent to an American prison. Roberto however is hesitant, showing his inexperience with the magic side, saying that persons like Othinus are usually sent to places like England. Touma says that they ran across the three major churches and that they cannot be swayed, determining to kill Othinus. Roberto falls into silence, but Touma continues to speak, asking him (referencing that America's rules act as the global standard) if there really is no path for Othinus other than death. After a pause, Roberto says that Othinus would be charged with crimes against humanity as she attacked an enemy without declaring war, which would certainly lead her to be executed. Touma becomes worried on Othinus' survival, but Roberto continues to speak. He says that on the other hand, GREMLIN isn't accepted as a nation under international law, nor are they registered as a legitimate military force, technically making those crimes against humanity and war crimes inapplicable to them. He however states that such reasoning would be quite tricky to pull off, but says that even they pulled it off, Othinus would still be guilty due to her actions, imprisoned for a long time, though it would be possible that she would get a pardon to lessen her sentence. But Roberto says that it'd be best to think there would be almost no chance of her getting out.[25]

After hearing this, Touma cannot help but laugh, and says that it is fine as long there is hope then he and Othinus can accept it. Roberto asks if Touma truly understands, to which he replies that it is much better than having her killed in a frenzy. Touma then apologizes to him for thinking that America wasn't a major power in the world stage unlike Academy City and England for the science and magic side respectively, but says that America was the most rational ones when it came down to it. Finally, he says that America did what the science and magic sides could not. Hearing this, Roberto then tells Ingrid Martin that for their national interests and for the stabilization of the world, Operation Norse Wind is suspended. He orders them to release Touma and Othinus and continue their infiltration with the channel open for further orders, and then tells her to repeat what he just said. Ingrid Martin does so, and then has the soldiers release their bonds on Touma as well as that of Othinus. Touma then sees Othinus from a short distance being guarded by soldiers and goes toward her. As Othinus slowly regains consciousness, Roberto tells Touma that they won't attach an obvious collar on them, like a bomb on them, as a security measure, but says that the United States of America will be watching over them in hiding and maintaining a position to kill them. He says that would enough to replace an actual collar, with death constantly looming over Touma and Othinus.[25]

Back in the UN Headquarters, a heavy silence hangs down upon the conference room, with the representatives present there turning towards Roberto Katze after he ended his talk with Touma. He later apologizes to them and says that he is their enemy now. Apparently, Roberto meets no reprisal for this.[26]

From a UAV and through Ingrid Martin's observations, Roberto is able to get a glimpse on what is happening near Egeskov Castle as Touma tries to stop Othinus from killing herself. Ingrid asks the President what to do, to which he says he is also trying to figure it out what to do, not being able to fully grasp the situation as Othinus uses her magic. Roberto then asks if she can continue to keep track of Touma and Othinus' conversation. Ingrid says that there'll be a lot of static but it would be possible. Roberto continues speaking and says that though he knows that it would be a difficult request for you since she is tasked with cross-borders operations he still asks her if she is able to declassify the footage of Touma's battle with Othinus. He says to her that he wants to show the two to the world as they are and he wants to ask the world for forgiveness. Knowing how this would be affect the President's credibility as it would take more of the blame than anyone else on the actual scene, Ingrid becomes frustrated. She tells him, with all due respect, that it would definitely harm his approval ratings and that both Touma and Othinus are not American citizens. Despite this, Ingrid already knows what Roberto will say: "So what?" Thus, despite her remonstrations, Ingrid is forced to follow his commands.[23] With this, Roberto intends to hand the fate of Othinus to the world's judgment.

Roberto tells the others that he will be holding an emergency press conference, asking the others what they will do. Elizard says that she will leave that to people who want to stand out in public and says she'd rather handle the internal announcement. She says that she is worried that she won't easily calm her military obsessed daughter, who was eager to be deployed, and had her mobile fortress destroyed. Roberto is amazed and asks if she isn't dead set on killing Touma and Othinus anymore. The Patriarch cuts in and asks not to tease the Queen Regnant too much. With a sigh, he then says that he will focus on reaching those people in places America's voice cannot reach. The Pope also says that he can provide assistance as well. They then turn to the representative of France, the Maiden of Versailles. She says that France never sent anyone in the first place, and as such they have no reason to struggle as well. The Queen then says that it seems one of the world's problems is how the clever have a way of going unnoticed. This later leads to a small fight between them.[24]

Regardless, the various leaders begin their speech to their chosen constituents. The President asks those who are tuning in a rhetorical question: Is Othinus is evil? He says, according to what Othinus had wrought, that people will not hesitate in calling her a villain. However, he then asks if Othinus truly is irredeemable. He says that people who have been involved in these incidents isn't wrong to feel that they want to punish Othinus. However, he asks if it is right to punish someone who truly regret their crimes and are attempting to save someone at the risk of their own lives (referring to Othinus trying to kill herself in order not to let Touma go to the path of suffering that befalls him in saving her). Roberto says that he doesn't have any complicated philosophy about good and evil and that is why he is asking the people. He says that he is sure there are some hearts that would be saved by taking revenge, but says that there are also hearts that would be saved by giving her a chance. Roberto then asks again what the people thinks.[27]

He asks if they will kill the evil that is Othinus or if the will forgive it. Finally, he then asks them to do one thing, and that is he would like them to test the strength of humanity along with all of them.[27]

After witnessing Touma attempt and save Othinus, and later after the Fairy spell fully consumes her and then her into a 15 centimeter being, one of Roberto's soldiers, likely Ingrid Martin, throws a radio communication to her. Roberto says that at her current state there would be no way to keep Othinus from breaking out of an American prison, and as such there is no point in throwing her into even a maximum security prison. The Queen then cuts in and says that even if Othinus' current form and total amount of power contained have changed, she is still closer to being a magic god than human, though she has been weakened too far to ever use again. She then wonders about Othinus' lifespan in her current form, saying that since throwing her into a cell won't likely make a single difference to her, imprisonment will not accomplish anything. She then says that they need to create a new punishment that will be especially effective against her and only her. Othinus is then told that she must forever watch the world of happiness that she went as far as suicide to look away from, the greatest punishment humanity can give to her now that they have achieved victory over a magic god.[28] Thus, Othinus is subjected to an ironic fate that she had once subjected Touma to those many worlds ago.

Christmas Eve Arc[]

On December 24th, Roberto Katze is mentioned on the news as having joined in on social media with the trend of custom donuts prevalent in New York.[29]

Los Angeles Arc[]

Main article: Los Angeles Arc

Roberto had given permission for Academy City and Anglican Church to carry out Operation Overlord Revenge to destroy R&C Occultics HQ in Los Angeles,[30] but had been led into giving the go-ahead early by Vice President Darris Hewlane, with the mass disappearance of the city's population happening not long afterwards, early on the morning of December 26th.[31] Later in the day, along with Roseline and Darris, he attended a charity debate at the White House, where he faced criticism over the handling of the situation in Los Angeles from the leader of the opposition and other figures, while keeping an eye out for spies and sabotage connected to R&C Occultics.[32]

Roberto launched into a speech supporting the clones.

When the Sisters revealed themselves to support Touma's battle to defeat the enemy and thwart the attempt to frame Melzabeth Grocery, Roberto launched into a speech supporting the clones, laden with his own ramblings and also a trap to snare traitors, which Darris fell for, saying Melzabeth's name - something he should not have known. With the treachery revealed, Roberto and Darris ended up in a gunfight and clash of words, which ended with Darris abandoning the remote double he had been using.[4][33][34] After the incident was resolved, Roberto heard news of the Vice President's arrest in Los Angeles, as well as being reprimanded by Roseline over his actions (not helped by a lady he had been with the day before turning up at the gates).[35]

Character Art Designs[]

Design Evolution[]

Roberto Katze's design remains the same throughout the series. According to Haimura, he toned Roberto's "intensity" in order to lessen the similarities between him and Misaka Tabigake.



  • Because of his appearance and quirks, he is often referred to as Iskandar of Fate/Zero fame by the fandom.
  • The phase "Yes we can!” is referenced from the real life President Barack Obama during his 2008 speeches.


  • (To a reporter in NT volume 3): "When I truly go after a woman, I give her such a memorable experience that any previous complaints are blown away."
  • (To Accelerator in NT volume 3): "I’m the goddamn president."
  • (To his attackers in NT volume 3): “Now I have a question for you, mister. Do you think the strong man I wanted to be was someone who would obey inhuman orders to save his own skin? Do you think it was the kind of man who decorates himself with his position and political power but pisses himself at the sight of a handgun? Do you think my dream was to become a chicken who is so overcome with fear at the thought of a single bullet that he abandons an innocent child who has been taken hostage?”
  • (To his attackers in NT volume 3): "Tell me, mister. What do you think the kind of strong man I longed to be would do in a situation like this that angered him to the bottom of his heart?”
  • (To Cinesic Evers in NT volume 3): She uses those techniques that a certain sadistic British princess (who would make a good tsundere) showed us during British Halloween and that we saw all too much of during World War 3.
  • (To Misaka Mikoto in NT volume 3): "She’s right, girl. If you want to get yourself a guy, you need to change into a skimpy swimsuit and have a beer in one hand. All you have to do then is press your chest up against him and undo your bikini. Your point will be even more obvious if you do it near a beachside motel."
  • (To the Anti-GREMLIN Alliance, from NT 8): "Any true fools who aren’t afraid of death will come with me."
  • (To the Anti-GREMLIN Alliance, from NT 10): “Sorry, It looks like I’m your enemy now.”
  • (During his speech, from NT volume 10): “I would like to test the strength of humanity along with all of you.”
  • (During his speech, from GT volume 4): “I came from outside this country. In fact, I got my start as an undocumented immigrant who crossed the Mexican border with means I’d rather not get into here. From there, I learned to read and do math, I successfully modified the election laws, and then the American people chose me to be the third Hispanic to ever serve as president!! If a high school dropout like me can be elected, then anyone has a chance. I carry the hopes of so many people in this great country. Race? Ethnicity? Religion? Gender? Language? Education? Class? They can all eat shit. Here in the best damn country in the world, we go around tearing down those meaningless barriers, so why the hell should we criticize people for the circumstances of their birth!? Here in the land of the stars and stripes, we need to smile and welcome in anyone who shows up at our doorstep, no matter how they got there. And that goes double for these girls who have chosen to take up weapons and risk their lives to save 30 million of our own people! To take back Los Angeles!! And to protect an innocent woman from being blamed for crimes she didn’t commit!!!!!!”
