Hamazura Shiage/Chronology (Shinyaku Toaru Majutsu no Index)

Freshmen Arc
Shiage is out watching a movie with Rikou, a movie recommended by Kinuhata, and they were clearly not enjoying it. The movie scene is actually based off of another series by Kazuma Kamachi, called Heavy Object.

Later, he is forced to split from the rest of ITEM due to an attack by several delinquents. He meets with Hanzou and discusses his plans for the future with Rikou with him. Hanzou cryptically comments that he has a job, but that such a job would conflict with Shiage's plans for the future and then leaves. He then meets Kuruwa and speaks with her for a bit, learning that the job that Hanzou has taken is to protect Fremea Seivelun. Shiage, realizing that Fremea is Frenda's sister, decides to help out Hanzou, while also keeping the rest of ITEM from getting involved, as he does not want to drag them back into Academy City's Dark Side.

Hamazura tracks Hanzou to an underground mall where Hanzou is protecting Fremea from an attacking Power Suit. Shiage defeats the Power Suit and manages to escape with both Hanzou and Fremea and hides out in a private salon that ITEM uses. However, their mysterious attackers are able to determine their locations and attack the building with a massive number of Edge Bees while Hanzou is out searching for Kuruwa. Shiage once again manages to escape, but is separated from Fremea in the chaos. He manages to destroy many of the Edge Bees, and fights Kuroyoru Umidori. However, Umidori is forced to retreat before killing Shiage when she finds out about how Accelerator is rapidly advancing on her position.

Shiage manages to fight his way out of the building, and sees Fremea. However, right afterwards she is attacked by a power suit piloted by Silvercross, while Umidori hurls a car at her. However, Fremea is saved from the car by Accelerator, who was nearby when attacked. Despite Accelerator's intervention though, she is still captured by the Powered Suit, Highway Cheetah.

Shiage asks Accelerator to help him get back Fremea, and after a somewhat rocky introduction, Accelerator agrees. Accelerator, having figured out what the mysterious attackers' purpose was, reveals that Fremea herself had no value on her own. What the attackers (A group calling themselves "Freshmen") wanted was to bring both Accelerator and Shiage together and make them work together. It is explained that though Accelerator and Shiage were both extremely dangerous on their own, they were not dangerous enough to require to be removed. However, now that they are working together, they are dangerous enough that the Board of Directors would be forced to remove them.

After his pursuit vehicle was disabled he was given the "Dragon Rider" power armor and motorcycle to chase after Fremea. He eventually saves her, but loses the motorbike in the process, and defeats Silvercross. Near the end of the volume, he and Hanzou stop an armored suit invasion and Hijacks the FIVE_Over to render Umidori harmless, though she managed to get one final attack that was blocked by Kamijou Touma, who arrived at the last moment.

Homecoming Arc
After Leivinia Birdway decided to move the conversation to Touma's house, he noticed Touma being slightly depressed and suggested alcohol to raise his spirits. Touma is separated temporarily from them and they manage to catch up to him at his dormitory. Shiage decides to call Touma "sensei," after seeing him be associated with and followed by many different girls despite being heavily intoxicated.

During the intro to magic, Shiage thought he might be able to protect ITEM and Fremea better when learning magic might be possible but was told by Touma that since Academy City had altered and change his brain he wouldn't be able to use magic. Shiage zones out of the conversation since he learned he couldn't use magic and had attention problems; this results in Leivinia slapping him.

About further in the conversation, members of ITEM show up continuing on the "Hunt for Hamazura" game. Takitsubo Rikou is the first in locating for Shiage because of his closeness with Frenda, this results in a humorously dark side revealed to Shiage terror. Mugino Shizuri and Saiai show up to conclude the race with Mugino kicking him in the face, Kinuhata Saiai being second and Rikou being last as you had to apparently touch Shiage to not be the loser.

When GREMLIN begin their attack Shiage tells Touma that he will him as everyone in Academy City owes him a lot, he leaves the dorm to help prevent Radiosonde Castle from dropping onto the City. Later he help Touma get to the magical tracking device by stealing construction equipment.

Eve of the Festival
Hamazura Shiage conspires with Kinuhata Saiai in order to have her accompany Kuroyoru Umidori to the Hero's Cave, a dentist clinic in School District 7, after noticing that she has been avoiding chewing with her back teeth. He installs gum into the ports where her nitrogen lances are fired out of, knowing that she would resist.

Shiage first appears with Rikou in the lobby of the aforementioned dentist clinic, waiting for Fremea Seivelun to finish. As Fremea screams, Shiage casually talking to Rikou about jobs that pay people to make children cry. Later, with Rikou, they accompany Fremea back to their dorm before going home. While Rikou tells him that they need money for some detergent, Shiage laments on how there is no sex appeal to her attitude. His lamentations ends when Rikou finally says that Fremea is gone, much to his irritation. He and Rikou later spend the night trying to find Fremea after learning that she has not returned to her dorm in School District 13.

During the Festival
Shiage plays a minor role in the latter half of the arc, but does a crucial part in its resolution.

Shiage first appears alongside Rikou, spending their entire night searching for Fremea, whom they found in a bench in School District 7, unharmed. While carrying the sleeping Fremea in a back alley, they come upon Fräulein Kreutune, who has now acquired the function of wanting to eat Last Order's brain. Believing her to be a drunk, they pay no mind to her. She mistakes Fremea for Last Order, and tries to lunge at her, but quickly realizes it isn't her and runs away. Fräulein's actions frightens Hamazura because he feels that he was just in a cage with a wild beast.

Fremea wakes up in Shiage's back, and complains about "him" getting lost. Since there are loose animals, the trains have been stopped, and the buses have been reduced, as such, they have are stuck in School District 7. Fremea then says that she is hungry, to which Shiage and Rikou take her out. For much of her meal, Fremea manages to annoy both Shiage and Rikou, the former trying to stay the latter's hand. After getting tired, Fremea forced her way towards Shiage's back, forcing him to carry her, annoying them both. Up there, she finds Last Order accompanied by Accelerator and Yoshikawa Kikyou.

Their reunion is cut short as chaos ensues, when Fräulein tries to lunge herself towards Last Order. Fremea, who is still clinging on Shiage's back is thrown down, after Fräulein mows tackles Shiage down to get to Last Order. Fremea and Last Order bear witness to Accelerator attacking her and her invulnerability. As Kakine Teitoku attacks with his Rhinoceros Beetles, Accelerator sends them down the subway tunnel in order for them to escape as he tries to engage in battle with Kakine. Yoshikawa Kikyou then gathers attention towards her, and states that Accelerator has bought them time and that whatever issues they might have they need to escape. Shiage agrees, stating just being in the same same place as them could get them smashed into pieces, but adds on how it would be dangerous to support him without a plan. Kikyou asks if he would support if he did have a plan, but Shiage just averts his gaze. Kikyou asks if he would support if he did have a plan, but Shiage just averts his gaze. Just then, the White Beetles come before them. But their attack never comes, a beetle malfunctions in trying to check the order of "Destroying any and all elements that obstruct our mission," due to the presence of Takitsubo Rikou and her AIM Stalker. As he rechecks his orders, he asks his fellow Beetles to assist him. Here, they list down what they think their mission objective is: "to defeat Fräulein Kreutune and eliminate the objective behind her actions, eliminate anyone who would obstruct the battle between Accelerator and Kakine Teitoku, secure the battlefield, eliminate the recent continuing threat to the City by defeating all dangerous elements," and finally, "to protect the residents of the City from all anticipated dangerous elements." However, they then shortly fire at each other, concluding that they, as well as Kakine Teitoku, are "also" dangerous elements in the City. Beetle 05 is then felled, and near Shiage and the others, asking what he was doing, to which Shiage replies not to ask him. It tried to target Last Order again, but the malfunction has taken hold, and determined that Last Order and the rest of them are not a threat. Beetle 05 tells them that he will save them in order to protect this order list from a fatal contradiction. Getting back up, Beetle 05 eyes' turn from green to red, indicating that he has indeed been lost from the will of the original. Perhaps, this is due to his close proximity to Rikou, at that moment. Moreover, a form of direction had appeared within Beetle 05.

Underground in the subway tunnel, the group flees, whilst Beetle 05 holds the other beetles off as long as his strength could bear it. The beetles concentrated their fire on Last Order, for they determined that she was the quickest method in robbing the reason for Fräulein's actions. When they came upon a locked door and Beetle 05 opened it for them, telling them to go as he fires another shell upon the ceiling, collapsing it upon the other beetles. And when all of them have escaped into another hall, they discovered that the door was too small. However, Beetle 05 paid no attention to this for he did not intend to beat the other beetles in the first place. Beetle 05 slammed into the door, shutting the egress from the other beetles with his body. Shiage questions his judgment, to which Beetle 05 states that it his plan, and that since he has left Kakine Teitoku's control, he can no longer renew his Dark Matter, and will break apart. He tells them that the only way to escape from the enemies that can regenerate infinitely is to block their path. But Shiage would not stand for it and demands for him to come as well, but Beetle 05 will not yield. And Shiage could only feel helpless, as Beetle 05 acts as a wall against the other beetles for them. He is later forced by Yoshikawa Kikyou and Takitsubo Rikou to leave. However, the group finds out later that they have lost the children.

Outside, Kikyou tries to contact Last Order, but she wouldn't answer, and is relieved that she did not, as it eliminates a means for her pursuers to track her location. Shiage asks what had happened, to which Kikyou says that it is most likely that there is someone protecting them from the beetles, to which Shiage assumes as the irregular beetle. As they try to figure out how to find them, Kikyou asks what they should do even if they did, as the beetles are ever close in their pursuit, citing their firepower and armor as a deterrence to their actions. As Kikyou, Shiage, and Rikou brainstorm on how to get pass their armor, Mugino and Saiai appears before them. Saia explains how they got here, to which Shiage explains to them the situation in "30 seconds." Mugino was polite in the beginning but became displeased as Shiage's story went on, and had grabbed Shiage by the collar. She is angry towards Shiage for having no idea where Fremea is, and allowing her to leave with a probably dangerous out-of-control weapon (Beetle 05), and the fact that he has no idea why she was being attack or who was behind all of it. Rikou and Saiai frantically try to stop Mugino from making Shiage worse off in her anger, but later tosses Shiage aside near a tree. Mugino tells that him believing that he will be defeated once he is spotted from whether he's 4 kilometers or 1mm away, as well as his plan on opposing the beetles as nonsensical. She is further enraged after he asks where they could find a means of attacking from kilometers away that can break through the beetles' armor. She tells that they all need firepower that can take out the likes of those beetles 5 kilometers away, and states that it is easier than spinning a pen in her fingers. Shiage still doesn't understand, to which Mugino asks if he thinks the 4th Level 5 is cheaper and harder to use than a rocket launcher, as Mugino as she continues to step on Shiage as punishment.

Mugino then asks Shiage, and asks what had happened to the security buzzer that Shiage gave to Fremea. Shiage's actions seem to indicate he forgot, and as Mugino prepares to deal out punishment, he takes out the GPS tracker to find the security buzzer, ending up next to the multi-level overpass. There, they find Fräulein Kreutune, and was about to witness the battles that was about to occur for her sake. Then, Cendrillon comes up to them, who rudely tells Mugino to point her to their apartment again, angering her. Cendrillon ignored their reactions and tells them that she has left some of her ingredients in back in the apartment, and that she needs them in order to resolve a large problem in the city. Mugino is annoyed and not wanting to deal with the situation took Shiage and told Cendrillon that he will show him the way to the apartment. Then, with all this commotion, Yoshikawa Kikyou tells them that the girls are together and are with a large rhinoceros beetle, though she says that they are safe for the moment. Mugino, unused to having information being given without compensation in return, is surprised with Kikyou's actions, which she points out. She tells them that Kakine Teitoku is trying to kill them, and asks for their help. Mugino says she doesn't care as long as she gets Fremea away from Last Order, but Kikyou notes on what Fremea would feel if that were to happen.

Shiage tries to diffuse the situation, saying that if Fremea's friend is about to be killed, there's nothing wrong with fighting to save her. With that, despite in her displeasure, concedes, and asks where Kakine is, to which Kikyou states that they are in the underground passageways of the multi-level overpass, noting on the behavior of Level 5s fighting. She also states that she also has to deal with Last Order being eaten. Cendrillon then speaks up on how she will be needed to keep the girl from being eaten, surprising Mugino. Cendrillon states that to protect Fremea's friend, they also must protect Fräulein, as is the will of Kamijou Touma. After Mugino translated her words, Shiage recalls the softhearted mood that pulled others together in Hawaii after hearing Touma's name. They then ask Cendrillon on how they could stop Fräulein Kreutune, to which Cendrillon says that Fräulein Kreutune will eat a specific person's brain, and that she left the materials needed to use against her back in the apartment. With that, they all went their separate ways in order to protect Fremea's friends, with Mugino going to the multilevel overpass.

Shiage and Rikou leads Cendrillon back to their apartment, as Kikyou tags along. There, Shiage overhears Kinuhata Saiai complain to herself about doing all the work, even though she handed off the dark side investigation to Mugino, she is missing the Ichihanaransai. She leaps up after being heard by Shiage as she relieved herself by shouting, and beats him up with a wrestling move. As Cendrillon prepares the ingredients left alone, Kikyou asks if this is truly how they could make a human body, doubting the ingredients before them. Still lying on the ground, Shiage asks what they need to do. Kikyou translates Cendrillon's words, stating that they need only to follow instruction using the specified amounts, knead together the excess brain material into a paste that has a similar structure to Last Order's brain. Kikyou states that she knows her brain structure, then sends out the plans to those involved, except Accelerator, who's mobile phone could not reach the message him at the moment.

Shiage asks if this is really Touma's instructions, to which Cendrillon replies that she doesn't know, and that tells that it may be a problem if the replica is too perfect, as such, they should create another replica that is made out of candy, and feed Fräulein Kreutune with it instead.

Shiage takes the replica in a clear bag, and heads out for the multi-level overpass. He is asked by Rikou if the plan would really work, to which he replies that he has no idea, though it does make a bit of sense. He the comments on being stuck behind the scenes, but tells that even if he doesn't like his role, he shouldn't slack off.

It is presumed that Shiage was the one who gave the brain to Fräulein, and later witnesses her embrace with Last Order and Fremea, as well as her change of form. He most likely took Fremea back to School District 13 afterwards.

Agitate Halation Arc
Shiage appears in School District 13 on a stake out near Fremea Seivelun's dormitory with Kinuhata Saiai to watch out for attacks from the remnants of Freshmen. Throughout the day Shiage has as a strange sense of foreboding but paid no heed to it. Seemingly to relieve this feeling, he notes to Saiai that they are becoming complacent, though Saiai states that an attack from them is unlikely after they have defeated Kuroyoru and Silvercross. Shiage states that she isn't taking their mission seriously, to which Saiai points out that Shiage himself as a hypocrite for always is trying to partner up with Rikou. Tired, Saiai asks if they could end their routine as Fremea has the Rhinoceros Beetle as her guardian, attached on her backpack. Just then, right on schedule, Fremea's dormitory turns off its lights for the night. However, they then discover that Fremea turned her lights back on. Saiai tries to call her as she is still awake, but she doesn't answer. Suddenly, the alarm for the emergency exit in the dorm is activated, which confuses Shiage as Beetle 05 could've easily taken care of any enemy. Saiai however, doesn't care about the details and urges Shiage to quickly investigate what's happening.

As part of their investigation, they simply asked the dorm supervisor of what had transpired, and stated that there was no fire nor robber. In other words, they had learned nothing. Shiage and Saiai later hear the sound of explosions as the result of Kuroyoru Umidori's battle with Rensa, who has initiated another phase of her and Yakumi Hisako's plan. Fearing that Fremea is involved, they rush towards the sight of the blast. The both of them suspect the Freshmen, though they are open to any possibility. Suddenly, an exhausted Yakumi Hisako arrives, telling them to stop, though she realizes that they would be the easiest hero to draw using Fremea Seivelun (relating to the Agitate Halation). This confuses Shiage, but Hisako too realizes that words have no meaning to "heroes", and decides to try a more convincing reason for them to give up.

Then, sounds of chaos erupts of all around them. Saiai warns Shiage that they are surrounded, and there they see innumerable cockroaches surrounding them, all under the control of Yakumi Hisako. The two are already disgusted enough but Hisako reveals that she has modified their brains to make them eat anything and everything, even people. The man-eating cockroaches slowly approached them. As Saiai has the Offense Armor, she is protected from the roaches, and suggests Shiage split up with her. Shiage hesitates but Hisako cuts into their conversation, warning them that it is a dangerous gamble as though they may not be able to eat a wall of nitrogen created by her Offense Armor, she may not able to create the wall in the first place. Saiai points out that the conditions are similar to Hisako, as she too has something that protects her and sends orders to them. Shiage tries to stop Saiai from advancing, but Saiai points out that Hisako may have the ability to attack multiple places and that they can't leave Fremea unprotected. Hisako however taunts them of even believing that they can get away, but Saiai is unperturbed. Still confident, Hisako explains the reason she chose roaches is because the disgusting image they sow, causing more mental exhaustion than other insects like termites, and affecting her Personal Reality which controls Saiai's powers. The explanation alone was almost enough to overwhelm Shiage, but Saiai ignores it and tells him to run. Shiage still hesitates, but Saiai asks him if he is willing to let Fremea see the grotesque things that came from the dark side of Academy City. She reiterates that being the one that Fremea trusts is and is attached to the most, he has the obligation to live up to the trust, and that means not allowing her to see the things that the both of them have seen. With a nod, Shiage runs away from the battle, apologizing to Saiai, though she answers that she never even thought he could be any help.

Angry at his own powerlessness, Shiage shouts as he runs away from Saiai and Hisako. After staggering a few times, he comes upon something that crashed from the roofs. It is an injured Umidori, and as Shiage tries to go towards her, Rensa appears before him. She refers to Shiage as a low level problem, and that it would be difficult to convince him that Umidori is her enemy. She concludes that Shiage is expendable to the experiment, and prepares to attack him. Umidori, unable to speak, hastily writes down that Rensa is a cyborg, a more advanced one. Suddenly, Rensa's back opens up and a large mechanical flower opens up from it, performs some sort of calculation, and then folds back within her again. She then fires a nitrogen spear, and Shiage immediately concludes that she can copy esper powers, and that she can construct output points similar to Umidori using her mechanical arms. However, that is not the only thing she can do, as she boasts that she can freely switch through all Level 5's powers other than the 7th ranked, and any esper within 200 meters. Rensa relates on how she will kill him to fix the error and then continue as planned to have Umidori framed for killing Fremea. After some pondering, Shiage is still confused on why the assassins would go out of their way to try to kill Fremea in such a massive scale and frame it on Umidori. Moreover, he ponders on why she hasn't killed the both of them yet, and concludes that Rensa wants them to run away in order for them to draw out Fremea for her. Seeing the cyborg, Shiage assumes that Rensa has to hold back in order for her not to accidentally kill them. Whispering to Umidori, Shiage says that he will charge at Rensa, making her falter and block her vision. Shiage tells Umidori that she needs to stab a spear from behind him, even if she needs to stab it through his body so long it won't kill him. Shiage's plan is under the assumption that she will not use Accelerator's redirection for them to stay alive and escape.

With that, Shiage begins charging towards her. However, though Umidori is impressed by Shiage's bravery, she realizes the absurdity of the plan working under their circumstances, and has come to conclude that Shiage will be abandoning her in order for them to destroy each other. Wanting none of that, she determines that she will kill Rensa but not for Shiage. She does nothing as Shiage charges towards Rensa who prepares to use her arsenal of powers. By the time she realized the truth, it was too late. Shiage is struck down by hundreds of wings of Dark Matter, though not killing him as Rensa has intended. There, Umidori screams due to her feelings. Seeing as Shiage is injured, he cannot lead Rensa to Fremea, therefore, she concludes that she will kill him and use another acquaintance to find Fremea Seivelun instead. While on the ground, Shiage apologizes for not working harder in gaining her trust, making Umidori feel guilty. As Rensa prepares for the killing blow, Shiage tells Umidori to abandon him, as Rensa needs her alive to frame her for Fremea's killing. He suggests asking help from ITEM before Rensa get the chance to use them to find Fremea. But Umidori can only drown in her own guilt, blaming herself for the doom Shiage will have to pay in her stead. Suddenly, Kamijou Touma finally arrives and prevents her from killing him.

Both Shiage and Umidori are on the ground during Touma's domination of Rensa and her eventual defeat after trying to copy the Imagine Breaker. Touma approaches the two of them to check on their condition. Shiage states that he is not going to die right away, but tells him that he'll be a burden. He says that he and Umidori will hide, and Kinuhata can take care of herself. However, he states that the real problem would be Fremea. Shiage hands his phone to Touma, where he can follow the GPS signal of Fremea's security buzzer with it. Touma understands, but tells Shiage that it isn't him that Fremea is waiting for, just the replacement. Touma tells Shiage not to die while leaving him with her. And Shiage agrees with a handshake. Shiage later takes Umidori to a certain hospital to get treated.

After we the events of the arc, Shiage meets the wheelchair-bound Umidori, as well as Kamijou Touma, all three bandaged. Touma asks for Shiage and Umidori's condition as they were the worst off. Shiage states that he will not be long there, but Umidori's stay will take a while. Umidori states that it is not a problem, and shows off the movements of her arms, which is still somewhat awkward. Touma's gaze falls upon Umidori, and in a strangely odd voice, says that she will kill him if he says anything unnecessary. Shiage then asks how much Touma found out. There, Touma states that Rensa was completely destroyed, as such she won't come back to enact her revenge. Touma then says with a heavy heart that maybe the reason she was destroyed was because she lost control and not because of the Imagine Breaker. A silence pass by as Touma ponders on Rensa's fate and her sacrifice to save Hisako. Touma then tells of the involvement of Yakumi Hisako in the Agitate Halation Project and Fremea being in the center, but that is alone the limit of his knowledge and references the dangerous things that were found in the hospital Hisako works in. Umidori then asks if he is satisfied with that conclusion, stating that the truth will never come to light, as the truly dangerous things are still hidden within. Shiage asks if there are still people out there who will use Agitate Halation. Umidori says that it doesn't have to be anyone directly related to the project. Shiage then falls silent after hearing Umidori's words. Touma replies that he knows what the stakes are, and it is the reason why he retrieved all 40 hypothalami that is used for Rensa, impressing Shiage as Touma did not go straight to the hospital. Here, they saw the grim reminder that not everyone can be saved. Seeing them, Umidori asks if what Touma intends to with them. Touma replies that he will have them put into cold storage until the time technology has advanced enough to find a way for them to be truly saved. As Touma leaves, Shiage calls back to him, asking what he is going to do now. Touma replies that he will do the same thing as always: "No matter how many times I reach game over and no matter how many times I must pathetically hit continue, I will not stop moving forward."

Magic God Othinus Arc
In the final recreation of the world by Othinus created specifically to break Touma's spirit, known as the Version_Omega world in-text, where several characters from the original world have been "saved" or have not experienced great tragedy, Ritoku survives and has somehow become part of ITEM as a subordinate. Hamazura Shiage, Hattori Hanzou, Komaba Ritoku, and Fremea Seivelun are first sighted by Kamijou Touma entering a family restaurant where ITEM is in, apparently late. Here, Saiai asks why they are late and why their efficiency is dropping as they gained more subordinates. Shiage blames Hanzou for the shortcut they took, but Hanzou says it is because Ritoku could not leave a vending machine with a roulette alone. Frenda, who is alive in this reality, wonders how Fremea could be so attached to a macho man like him.

St. Germain Arc
Shiage does odd jobs with the help of Stephanie Gorgeouspalace, wanting to make money for him and ITEM without resorting to thievery. After testing a mass production version of the Dragon Rider with Aneri the driver-assistance AI, Stephanie arrives and offers him a job in transporting cargo to TV Orbit in the Dianoid, where ITEM is waiting for him as well, using Power Lifters.

After arriving there, the two prepare to use their Power Lifters to transport a large die-like container to TV Orbit, which is found in the mid-level of the Dianoid. Despite learning how to use the Power Lifter recently, Shiage is able to use it well. As they begin transporting the container, Shiage notices Kanou Shinka slip into the cargo bay. He threatens him that he is the 6th-ranked Level 5 Aihana Etsu, though Stephanie scares him away. After St. Germain seals the Dianoid, preventing people from escaping and entering the building, the elevator that Shiage and Stephanie are in with their Power Lifters. As Stephanie is unable to communicate with TV Orbit on what they should do next, Stephanie decides that they must continue with their delivery even if the elevator has broken down. They escape into the elevator shaft while carrying the large container with the legs of their Power Lifter.

They later break out of the elevator shaft and arrive at their destination. They later deliver the container to TV Orbit, and from there ask what has happened. The two discover that the Dianoid has been sealed preventing anyone from leaving. The woman from TV Orbit asks them if they could use their Power Lifters to break open the emergency stairs as they have done with the elevator doors. Stephanie makes an attempt but fails due to the carbon nature of the Dianoid. Stephanie believes that they should wait for Anti-Skill to come and burn their way into Dianoid, but Shiage is adamant that there is someone behind the sealing of the Dianoid and that waiting is the wrong choice. Seeing it now as part of their job, the two later go down back into the elevator shaft and try to find the source of the sealing of the Dianoid and end it. Stephanie later pushes Shiage in order to give him the opportunity to solve what was happening. Shiage himself encounters St. Germain, at which point Aneri suggests to Shiage that they should hide. Here, Shiage fears for the worst with ITEM encountering the man, and opts to take him right then and there. His plans fall apart as Kamijou Touma falls down upon him. After finding their bearings, Touma, whom has met St. Germain earlier and claimed to be a Magic God, pleads to Shiage to wait until they find a way to deal with a Magic God. Shiage doesn't care about Touma's explanations, oblivious of the true power of a magic god, wanting to see to it that ITEM is safe. Seeing as Touma will not allow him to fight St. Germain, the two begin fighting.

Despite the massive advantage that Shiage has with his Power Lifter, Touma manages to force the fight on his terms, pulling Shiage out of the Power Lifter. Touma has the upper hand until Shiage surprises Touma and hits him in the thigh. Shiage later knocks him out, beating the hero World War III and the one who solved the GREMLIN crisis. While running about trying to find ITEM, Touma runs to him again as they are attacked by St. Germain's Chambord spears that goes through the bodies of people. Shiage believes that he has settled things with Touma, to which Touma replies that he did but says that the St. Germains will not listen to them. As they are enclosed by St. Germains and their spears, Touma tells Shiage to flee and go to his girlfriend as he will handle the St. Germains himself. Guilt-ridden Shiage takes Touma and flees, surprising him. As they flee, they are saved from being skewered by the Chambord spears by the timely arrival of Stephanie.

Hiding in a theater's third story seats, Shiage sees a beam of light pierce nearby, showing to Shiage that at least Mugino is fine. Touma then discusses his plans on saving Shinka, whom referred to himself as Aihana Etsu to Touma. He then discusses the inconsistencies in St. Germain's actions surrounding him, the sealing of the Dianoid, and St. Germain's obsession with Shinka. This leads to Touma to conclude that St. Germain wants Shinka to do something for them. Touma then tells Shiage that Shinka wanted him to search for the "last vestiges" of Frenda in his place. Hearing this, Shiage confirms to Touma that he knows who Frenda is. Touma tells him that the secrets of Frenda may be the key to breaking Shinka free from St. Germain and that they need to search the upper level for clues about her. Hearing this, Shiage agrees and teams up with Touma. After climbing up an elevetor shaft, the two arrive at the upper level, and with the help of Aneri, manage to find Frenda's room. After entering the room, instead of finding bombs as one would expect from Frenda, they instead find birthday presents for every one of her acquaintances, even Shinka. There, Shiage realizes that the strange duality of Frenda's personality. Shiage sees a recording of Frenda dancing for Mugino and vows that he will never let Mugino see it.

Despite all this, Touma finds that nothing here would help Shinka solve how Frenda disappeared. Just then, they see security footage of Shinka and the St. Germains in the basement of the Dianoid, and finds out that Shinka is blaming Touma, who is known for saving people whenever he is present, for not saving Frenda. Hearing this, Shiage is disgusted by the fact that Touma is getting blamed for something that he has never been involved in, and is shocked on how accepting Touma is of the blame. Touma understands that Shinka isn't thinking rationally as he is being manipulated by St. Germain, but is willing to have Shinka take his anger out on him. Shiage tells Touma that the fact that other people using Touma's presence in the incident that killed Frenda and others as if his existence determines who lives, spits on all those who tried to survive. Touma agrees that the world doesn't revolve around him and that he is only fighting for his own desires. In the end, Touma decides to save Shinka despite wanting to kill him, which Touma says is because of his own selfish desires. Hearing this and seeing Touma act, just makes Shiage think that Touma truly is a legitimate hero. Touma is willing to have Shinka fulfill his vengeance on him. He instructs Shiage to save Shinka with his Power Lifter after Shinka loses his reason to fight.

Just then, they are alerted that the Dianoid's graviton-style artificial gravity control device is being tampered with by St. Germain and is likely being turned into a gravity bomb. Shiage wants to prioritize the bomb, but Touma is adamant in saving Shinka. The conversation shifts to St. Germain's inconsistent schemes, with Touma telling Shiage that the St. Germains are not after Shinka or the gravity bomb but something else entirely. Shiage is completely out of the loop as Touma speculates about the structure of St. Germain and explains it in layman's terms. Returning to rescuing Shinka, Touma still wants to go through with his plans, to which Shiage, having enough of it all, knocks Touma off his feet. Here, Shiage tells Touma to stay back as he will be the one to take Shinka's revenge in his place, not wanting Touma to die for the sake of Shinka's life. Before trapping Touma in Frenda's room, Shiage confesses to Touma that Shinka should have a better reason to have revenge on him because he wasn't there to save Frenda back then. Shiage later leaves for the lower level through the elevator shaft again.

Shiage later arrives and tells him that hat he was the one who let Frenda die and that it makes no sense for him to attack Touma as he is a much more suitable candidate for revenge for Frenda. St. Germain tries to intervene but Shinka stops them. Shiage urges Shinka to fight him and he relents, despite the fact that he knows that he is only hurting himself by doing his revenge. Little did they know that Touma has arrived, sneaking into the basement. Not wanting to let Shinka fall into vengeance, he tosses the gift that Frenda prepared for Shinka prior to her death next to him. St. Germain tries to intervene but Shinka stops them. Here, Shinka sees that it was a voice message from Frenda for his birthday. The message has Frenda admire him for being a crybaby, and that she respects him for it as it prevents him doing awful things. There, Shinka is finally lifted from his despair. He casts aside the shield, the name of Aihanu Etsu, and calls himself Kanou Shinka again. He tells St. Germain that he will not accept him. Realizing that their ruse has been found out, destroys Frenda's present, though Shinka remains steadfast. With that, Kamijou Touma and Hamazura Shiage decides to aid him against St. Germain at the same time as their respective group of friends arrive in the basement.

Much of the battle has Shiage, along with Touma, protect Shinka from the attacks of the St. Germains and their plant matter creatures. It is also thanks to Shiage and Aneri that they are able to detect the release of carbon monoxide by the St. Germain's plant matter creatures and has Mugino use her Meltdowner to burn the air to prevent their suffocation. He also calls out Mugino in nearly hitting Shinka with her Meltdowner and references her involvement in the events that lead to Shinka siding with St. Germain in the first place (her killing of Frenda). Finally, with all their combined efforts in delaying the St. Germains, Index and Othinus are able to create a countermeasure against the framework that makes up the St. Germains and is finished off with a punch on one of them by Shinka.

After the defeat of St. Germain, everyone leaves Shiage to deal with the graviton-style base isolation structure, much to his chagrin. Only Rikou remains by Shiage's side. She tries to get close to Shiage but is prevented by Aneri, the AI of Shiage's Power Lifter, making Rikou jealous.

Magic God Invasion Arc
Shiage participates in the Anti-Crime Orientation, roleplaying as a hostage. He, however, is mistaken by Fremea, who is roleplaying a police, as a criminal, much to his chagrin.

Shiage tries to change the subject toward Arrowhead Comet, but she refuses to listen. As they try to cross the road, Shiage gets a message from Aneri. Although the message was just gibberish, the message stopped Shiage in his tracks, preventing them from getting run over by High Priest's destructive chase with Touma.

Salome Arc
On December 4th, Shiage accompanied Rikou to a bank so she could sever ties with the old ITEM bank account. While waiting for her, he was approached by Salome who was targeting members of the Kamijou Faction. Salome attempted to provoke Shiage, taunting over his position as an errand boy for ITEM, however Shiage didn't respond in the way she had hoped. After Salome decided she wouldn't gain anything from attacking him, Shiage watched as she set her sights on the vault as the guards moved in before using her External Offering to attack, causing the building to tilt diagonally.

Element Arc
Around the start of the abnormal December heat wave, Shiage went out for an early morning jog but was soon brought to a halt by the heat. He then ran into an old man who he often met during early morning jogs, who was prevented from walking his dog. The two briefly discussed the abnormal heat and how they hadn't heard anything about it in the media. After Shiage suggested the underground tunnels as an alternative to the hot asphalt for the old man's dog walk, their attention was drawn to a commotion nearby and saw a group of office workers running up the underground stairs, being chased by Elements. As a couple of mantises turned their attention to the two, the old man was pulled away by his dog, leaving Shiage to run from the Elements and the fleeing crowd.

Aleister Crowley Arc
On December 11th, following the incident at the Windowless Building, Aneri attempted to alert Shiage by flashing 'warning' on his smartphone, though he didn't understand what Aneri was trying to warn him about.

Return to England Arc
Following the evacuation of Academy City on December 12th, Hamazura Shiage and Takitsubo Rikou accompanied Aleister and Touma's group on their journey to the United Kingdom in order to seek out Coronzon's influence and seize the demon's achilles heel. Separated from the others during the landing at Dover, they appropriated a car to continue their own journey, with Nephthys and Niang-Niang tagging along with them in the back. On the way to London and with the Crowley's Hazards pushing forward, they picked up nuns of the Agnese Forces, eventually dropping them off at the British Museum after getting caught in the crossfire between the Crowleys and the Divine Mixtures. Not long afterwards, the group saw the activation of Isis-Demeter.

Around the same time as the reproduced Golden Dawn were pursuing Aleister's group, Shiage's group started driving again after the Magic Gods alluded to something emerging. Passing through Piccadilly Circus, they came across and picked up the injured Dion Fortune, who had been caught in the bombing of the Naked Shopping Center by the Lady of the Masquerade Ball's Taphthartharath. She remained with them during their remaining and during the drive up to Scotland, until she reverted to cards along with the other reproductions after Aleister disrupted the flow of power to their grimoire bodies. Upset at the look of resignation on Fortune's face when she came apart and unable to accept the unfair outcome, Shiage declared he'd take her back no matter what.
