Kamijou Residence

The Kamijou Residence is the current residence of Kamijou Touma, the main protagonist of Toaru Majutsu no Index. Located on the seventh story of an 8-story student dormitory for boys in School District 7 of Academy City, one can get access to the floor via elevator or stairs.

Touma's room is directly next to his friend and classmate, Tsuchimikado Motoharu.

Exterior
Touma's family name can be seen outside of his room, written on a plate, to designate his ownership of it. The doors have an auto-lock system, although for Touma in particular his is brand new after the events in the Index Arc.

The back of the building also has a balcony for Touma's room, though since the distance between two balconies is only two meters apart it is easy to move from balcony-to-balcony; it can be accessed by entering the room and sliding open the glass door.

Interior
Interior is rather spacious, having enough space for a one-person bed as well as a coffee table and television, the room also contains a refrigerator and enough space for bookshelves, where Touma keeps his books and manga. There is also a kitchen. Near to the kitchen is the door which leads to the laundry room and the bathroom.

It seems that the walls of a room is not thick enough to drown out the sounds of the adjacent rooms, as Tsuchimikado Maika warns Touma after she moves in with his step-brother temporarily that it might get noisy later in the night.

Index Arc
The room makes its first appearance the morning after his duel with Misaka Mikoto on a certain Bridge, where the only resident was Touma wherein he awakes and finds an unconscious Index hanging on his balcony window. After parting ways with one another in that morning they find themselves reunited when he returns to the now empty building due to it being the beginning of summer break and there are no other students there. Touma then did battle with Stiyl outside his room with his flames that later draws Anti-Skill forcing Touma to flee with a badly wounded Index. After the conclusion of the arc, the church allowed Index to live with Touma - along with Touma's concealed memory loss. Index becomes the first guest resident of Kamijou's dorm room.

Deep Blood Arc
With Index now staying with him, she takes control of his bed forcing Touma to sleep in the bathtub. Because he is still an adolescent boy, he locks himself in the bathroom at night to prevent himself from doing something that shouldn't be done because whenever Index gets to the point where she’s in a deep sleep, she sleepwalks and opens the lock of the bathroom and go to Kamijou’s side.

After returning from eating outside, Touma notices a lump in her clothes and discovers that she is carrying the kitten they found earlier despite his protests. Index has decided to keep the kitten and name it Sphynx despite Touma's disapproval, but eventually relents to meet up with Stiyl. To his surprise he finds him outside setting up runes of Innocentius outside of his dormitory room in order to protect Index from anyone who may want to take her, which later proves useless when she chooses to leave of her own accord to investigate his odd behavior and follows the mana trail that Stiyl left leading to Misawa Cram School.

Sisters Arc
After the Deep Blood Arc, Himegami Aisa pays a visit to Touma's room and helps Index with the fleas Sphynx has gotten. Misaka 10032 visits Touma's dormitory to help him carry the juices that he procured illegally from a broken vending machine with Misaka Mikoto, upon arrival it is revealed that Tsuchimikado Motoharu is a neighbor of Touma, and is warned by his step-sister, Maika that there might be some noise from them later in the evening. Index and Himegami (much to their surprise as Touma has somehow acquired another female), are trying to remove the fleas that has apparently infested Sphynx. After a momentary argument dealing with the ethical issues regarding the method both Index and Aisa would try to get rid of the fleas, Misaka 10032 assists them by using her powers to kill the fleas off Sphynx, and leave him relatively unharmed before leaving, much to their amazement. During the night of August 21st, seeing as Touma is once again nowhere in sight, Index decides to leave the dorm and goes to Komoe's house for food.

Three Stories Arc
August 31, 12:00 AM. Touma discovers in the middle of the night that due to his excursion during the summer with the magic and science sides, he has yet to do any of his summer homework, with roughly 24 hours left for him to do it all. Meanwhile, at the same time, Accelerator passes by the Kamijou Residence after defeating a few delinquents trying to attack him after rumors floated about that he was defeated by a Level 0.

After his fight with Etzali, Touma continues to try and do his homework back at his apartment, and is later forced by Index to go out for dinner. After both Touma and Index left the building, Yamisaka Ouma, a magician wearing an Azusayumi gauntlet on his right hand, successfully enters Academy City, after defeating the Anti-Skills, and arrives at the apartment building looking for Index. He uses his magic to jump several stories and attack the dormitory ruining it. However, he discovers that no one is at home and later uses another magic spell to search for her. Assumedly after being defeated he returned with Touma to leave Index behind in Touma's room before leaving Academy City to fight the magician who casted a curse, causing problems for both Judgment and Anti-Skill and to fix the windows Yamisaka broke. Touma returns tired and worn out having forgotten completely that Index was tied up by Ouma again and left at the dormitory, making a commotion regarding what they are going to do by biting him as usual.

Orsola Aquinas Rescue Arc
As ordered by Laura Stuart, Stiyl Magnus went to Academy City and 'kidnapped' Index from the outside of the dorm while she was discussing with Maika on how she was not able to be with Touma while he was at school. This was done as an excuse for her guardian, Kamijou Touma to get involved as well since he is part of the Science side, though according to Index this is unnecessary as Touma would come to his aid even if he did not ask. When Touma later returned to the dorm Maika informed him of what had happened and teasingly asked if this was a lover’s dispute.

Tree Diagram Remnant Arc
Misaka 10032 awakens and leaves a tank for recuperating purposes to seek the aid of Kamijou Touma in ending the crisis of the experiments being restarted.

Touma takes Itsuwa to his home and she cooks dinner for him and Index, where she begins cooking for the two of them. After seeing Itsuwa cook, Touma asks Index to clean the bathtub. Their neighbor Maika was drawn by the cooking and is impressed by the taste, and to her annoyance she returns next door to redo dinner saying "THIS LEVEL OF THING ISN’T GOING TO MATCH UP AGAINST THAT!" After dinner, it is revealed that Index somehow breaks the tub. With no bathtub, Touma, Index and Itsuwa head to a public bath in School District 22. She moved out after Acqua was defeated, due to the threat being now over.

After a long period of time, he "sobers up" after some head biting and then Leivinia Birdway begins the explanation of magic from its organization to capabilities. During one of the discussion breaks, he goes to a restrained Kuroyoru Umidori in his bathroom to give her some food. When Umidori tries to show off her cyborg ability and take his life, Touma displays being shocked by her ability and calmly ignored her attack with his Imagine Breaker. Much to Umidori's dismay, Touma treats her like an appliance and a child; she recoils from him when he then tries to see if she has cyborg cat ears under her hood. After finally finishing the discussion about magic, Leivinia was about to reveal the name of the true enemy when she detected the approach of Radiosonde Castle. She tells the three protagonists that Academy City is about to be destroyed, because it was tracking Touma or more specifically his right arm.
