Heaven Canceller

Heaven Canceller (冥土帰し (ヘヴンキャンセラー) ), often mentioned as "the Frog-faced Doctor" by Touma and many other people, is an exceptionally-gifted and benevolent physician known by those who were cared by him or informed personel. While he may seem just like any other normal doctor, this medical genius also happens to be an acquaintance of the General Director of Academy City, Aleister Crowley, as he manages the machines that extend Aleister's life span while still supporting the foundation of the city itself.

Appearance
He is bald-headed and his remaining hair has turned grey. He is always seen wearing a doctor's outfit appearing to be slightly fat. His face is his trademark being the appearance similar to a frog. It should be noted that the doctor might even poke fun that he looks as a Frog, as in his ID card he has a sticker that has a frog.

Personality
He loves to be relied upon by his patients and will do his best to fulfill their requests. The doctor has followed the Hippocratic Oath faithfully, even though he calls himself Accelerator's "senpai" and said he has lived through and seen much more darkness compared to Accelerator. He still wishes to help anyone no matter who they are and which side they come from, even after all that he has seen. After Vento's attack on Academy City on September 30th, he displays anger when warning Aleister to stop messing around with his patients, to which Aleister replied the only way for that to happen is to stop the machine that prolongs Aleister's life. However, he could not do so, since even after all Aleister has done he is still one of his patients. In Academy City, he is opposed to Kihara Gensei, with his benevolent methods and adherence to the Hippocratic Oath conflicting with Gensei's desire to advance science no matter the cost.

Background
Before meeting with Aleister in Great Britain, he was the one that came up with the idea of establishing Academy City when he first met Aleister Crowley in a small village in England many years ago when Aleister was on the verge of death from being hunted down by the entire Magic Side. He helped Aleister escape to Japan and helped him establish the city, but instead of taking on the role of the founder, he preferred to stay at a hospital, where he can care for patients like he had always done.

At some point in time, he was able to create a mysterious life support device that can overcome the problems of aging and life limit of a person in the past through some mysterious theory but later abandoned it as well any life-related research all together, it is assumed that Dark Legacy was part of this research. He was also present during Kihara Gensei's presentation of the Crystallized Esper Essence to the researchers of Academy City, confronting him of abuses during his research.

Heaven Canceller is referenced Yoshikawa Kikyou to be able to save Accelerator despite having his head is shot. He later proves this, after Yoshikawa Kikyou wakes up in a certain hospital after an operation conducted by the frog-faced doctor, the Heaven Canceller. He states that even though she was shot point blank with the military pistol, and in a vital artery, she survived because of the efforts of Accelerator, who although, unconscious, used his powers to control the flow of blood in her artery and not allow a single drop to spill, and allowed Heaven Canceller to operate on her artery with relative ease. He says that Accelerator does not look good, as his brain was damage, his verbal and calculation abilities will be affected, a necessity in using his powers, the very reason why he is called the strongest esper. Although Kikyou is saddened by this, Heaven Canceller says that she should not worry, he need only to use the troublesome thing that the experiment has left behind, the 10,000 clones, as so he could regain them using their network to perform calculations for him.[30] Kikyou asks about Last Order, to which Heaven Canceller tells that she is fine and is with a girl that is similar to her, Misaka 10032. Before leaving, Heaven Canceller tells Kikyou that their little escapades have forced the higher-ups to permanently terminate the experiment, though they are letting her go after killing Amai Ao, she is basically unemployed. Hearing this Kikyou is disheartened that she can't live as a researcher anymore. The frog-faced doctor then tells her that there are other paths and begins to leave. However, Kikyou raises her voice and pleads to him to save Accelerator, and that if he was unable to, then she will never forgive him. The Heaven Canceller, responds to her rhetorically asking who she thinks he is talking to. He continues by saying that this is his battlefield, and that will return from it, bringing a patient who has been fighting for his life.

Alone in the room, Kikyou remembers Accelerator's words regarding him: the man slaying 10,000 to saving the remaining ones. She smiles and says that Accelerator was able to do it because he tried.

Academy City Invasion Arc

 * Main article:Academy City Invasion Arc

Before the onset of the invasion, Heaven Canceller checks up on the 10 remaining Radio Noise clones in Academy City, and during his question of whether or not all the measurements for the clones would be enough for the new Tokiwadai Middle School winter uniforms they would be wearing, he witnesses Misaka 19090 unable to confirm, like all the clones present there, that they only need one measurement for the uniforms, leading to a fight as the Heaven Canceller complicates matters by pointing out that even though they are clones, differences in diet and exercise would lead to changes to an invidual.

During the course of the invasion, Heaven Canceller receives Index, as well as Orson, of the Hound Dogs from Accelerator, giving them refuge, and later contacts him regarding the Kihara Amata and Hound Dogs after him and Last Order, warning him to evacuate the hospital. Heaven Canceller says that based on the information retrieved from the Misaka Network, Last Order is still alive and is with an ordinary person, unfortunately they are being chased by a squad of Hound Dogs, though the exact details are unknown. Heaven Canceller then scolds Accelerator for his lack on focus on a single goal, stating that it is impossible for him to destroy Hound Dogs, kill Kihara Amata and save Last Order without a scratch on her, and advises Accelerator to just return Last Order alive, for if she is alive then Heaven Canceller will save her.

After getting rid of the Hound Dogs after him, Accelerator returns to Heaven Canceller's hospital as so he can ambush the Hound Dogs that are after Index and the Hound Dog he spared earlier. Hound Dog members later infiltrate the hospital Heaven Canceller works in to eliminate one of their own (the Hound Dog that Accelerator spared) and Index, and quite possibly everyone else in the hospital. Here, they discover that the entire facility's patients and personnel has been evacuated most likely into it's basement parking grounds. Here, the Hound Dogs (one of which was one of the Heaven Canceller's former patients) get a call from Heaven Canceller who warns them of the Accelerator's wrath and just quit Hound Dog and forget Kihara Amata. However, they do not heed his warnings, to which the doctor tells them not die as so he can save them as long as they are not dead. After the call they are immediately destroyed by the Accelerator in ten minutes.

For most the arc, Heaven Canceller hides in the underground parking space under the hospital. Heaven Canceller confronts Aleister Crowley on one concern: he warns Aleister to keep his hands off his patients. Aleister playfully asks him about what would happen if he would do otherwise, and Heaven Canceller just points out Aleister's role as a patient, like several of his patients in his hospital. In response, Aleister tells him that his actions will no longer be interrupted, cutting his ties with his old friend and kinde enemy.

However, Therestina manages to track them down, and with the proper warrant, takes the children away from Harumi, with the Heaven Canceller unable to do anything.

Abilities
Heaven Canceller is hinted to have a ability that allows him to heal practically any sickness or injury, even if it is terminal. He is said to be so skilled that he can distort God's rules.

He cannot however bring back the dead, patients must be brought to him alive in order for him to heal them and he is also unable to heal specific brain-related injuries, such as Touma's destroyed memories and Accelerator's computation ability; however, in the latter case, he was able to configure Accelerator to control his powers with support from the Misaka Network.

He also is the creator of the "Dark Legacy," a tool discarded a long time ago, probably during his young age, which is now on Aleister's hands and used to keep the #4 Level 5 Mugino Shizuri alive and preserve the brain of the #2 Level 5, Kakine Teitoku after the events of the Volume 15.

Design evolution
Introduced in volume 1, though not getting a design until volume 2, Heaven Canceller is described by Haimura of looking like a quack. According to Haimura, while drawing the doctor, Haimura thought that it would be less interesting if charactes would look like a moe character or good looking guy, because of that thought, eventually lead to the design of Sherry Cromwell and Vento of the Front.

For his design in the Toaru Majutsu no Index manga adaptation, and had him designed to look like a mascot instead of a character.

Quotes

 * "Who do you think I am?" (Said various times to various people when they asked about whether or not the patient could be saved.)
 * “Actually, there’s a close relationship between medicine and the supernatural… I don’t mean that there are ghosts inside this hospital, you know? It’s just that sometimes, due to religious reasons, a blood transplant won’t do, an operation won’t do, and saving one person’s life would end up with that person suing us. Thus, as a doctor, the way to treat these spiritual groups is to ‘follow what the patient says’” (Epilogue of Volume 1)
 * “Hn? Please don't be mistaken though. I prefer to 'do it' than to be 'done in'. And I prefer the delivery platform to the operation table--” (Epilogue of Volume 2)
 * "This is my battlefield, and no matter what, I will return from my battlefield with my patients healed" (Volume 5, epilogue. Said to Yoshikawa when she asked about Accelerator's survival.)
 * "I've seen a hell far worse than any you have ever seen, and I have survived. Don't look down on the profession of a doctor, I've probably seen more blood and tears than you, I just didn't become a tragedy. That is why I'm called Heaven Canceller" (Volume 13, Chapter 6. Said to Accelerator when he accused Heaven Canceller of being only a doctor and not knowing anything about the darkness of Academy City.)
 * "It doesn't matter if her arms are broken, her skin gets torn off, or even if her internal organs are damaged; as long as you get her to me alive, I will definitely cure her. I will protect her life, and regardless of any physical or mental wounds, I will heal it, and let her stand before you whole again" (Volume 13, Chapter 6. Said to Accelerator, telling him to focus on getting Last Order back as first priority, and not to bite off more than he can chew.)
