A Certain High School

A Certain High School is the term used to refer the yet-unnamed high school that the protagonist, Kamijou Touma is enrolled in. In the Toaru Majutsu no Index universe, it is the school in Academy City with the most named characters, next to Tokiwadai Middle School.

The school is located on a hill, and one needs to climb an inclination and a number of steps to reach its main entrance. It is assumed there is also an alternate way into the grounds, as staff members can park their vehicles inside the school grounds.

Appearance
The establishment looks like a typical Japanese-style school building. The school has a large main building, towering several stories and with several other buildings surrounding the main one. Like any standard Japanese school, they have lockers for the students, parking space for the staff, a faculty room, a cafeteria, and an auditorium, and the roofs are apparently accessible to any student in the school.

Around the school there are various areas of interest, such as open areas where students can congregate and consume their lunches; one is notable for being close to a small pond. The school also has a large field, probably used for sport-related events, as well as tennis courts.

Uniforms
The summer male uniform appears to be a white dress shirt coupled with dark blue pants. The winter uniform includes the same dark pants, but the students wear a dark-colored jacket of the same shade. The female uniform is a sailor fuku which comes in both dark blue with white and white with dark blue (the former color is the main color, while the latter is used for stripes and borders) along with a dark skirt.

Students seem to be able to make additions to their uniform if they wish, such as Tsuchimikado Motoharu wearing gold chains.

Toaru Majutsu no Index
Since Touma goes to school here, it is often featured whenever he is going to his supplemental lessons.

Kazakiri Hyouka Arc

 * Main article:Kazakiri Hyouka Arc

The school is prominently featured during this arc, where the second semester starts and Touma is forced to leave Index home to attend his first day of school since losing his memories. Here, he notes that he is quite nervous, as though he feels like a transfer student in a new school.

Later on Index follows Touma, and is presumed by the class to be the new transfer student, but is dragged away by Tsukuyomi Komoe where it is later revealed that Himegami Aisa is the new transfer student. Index later meets Kazakiri Hyouka in a cafeteria, and they become fast friends. Hyouka is later introduced to Touma, and later agrees to go to the underground mall with him and Index.

Daihasei Festival Arc

The school is later used as a battlefield against an opposing team in the Daihasei Sports Festival, where after Komoe was belittled by an opposing teacher, gave Touma and his schoolmates the spirit to defeat the opposing school, giving them a win.

Level Upper Arc

 * Main article:Level Upper Arc

The school is featured prominently in Episode 14 of the Toaru Kagaku no Railgun anime, where Level Upper users were required to attend a special class. Here, a melancholic Saten Ruiko and her friends spend the day relearning about Personal Reality, and discovers the meaning of surpassing one's own limitations. Komoe and Yomikawa Aiho appear during this episode and helps the Level Upper users realize that they can gain their own Personal Reality- their own ability- themselves if they try.

By the end of the day, the Level Upper users have an scan on their abilities, and though they remain Level 0, Ruiko and her friends discover that a few of their attributes increased. Ruiko herself notes that she will do her best after looking at her own results.

Year 1 Class 7
Year 1 Class 7 is the most prominent class in this school featured in the series, being that it is Touma's homeroom. The homeroom teacher is Tsukuyomi Komoe the chemistry teacher, who is beloved by the students of her class.

It is stated that the room lacks an air-conditioning system, though it is unknown if it applies to all classrooms in the high school. From Volume 6 onwards, the entire class knows Index and takes kindly to her.
