School District 7

District 7 (第七学区) is a large school district near the center of Academy City. It is bordered by District 1 and  District 8 to the north,  District 5, 18, and 22 to the east,  District 10 and  District 2 to south, and  District 15 and  District 9 to the west.

Primarily used for middle and high school institutions, the district is the primary setting of Toaru Majutsu no Index whenever Academy City is in focus. Nearly all named Science side characters reside in the district, specifically the protagonists of the stories.

Principles
As stated it primarily focuses on middle school and high school institutions, despite this, the district has several features that separate it from the other districts. For one thing, the district contains the mysterious base of the Academy City's Chairman, the Windowless Building, as well as the special area for prestigious all-girl schools, Garden.

Moreover, what makes the district unique is that despite its main feature for use of middle school and high school students, it is not solely composed of the things that fits its purpose. For example, District 15 focuses mostly on leisure and mass communication facilities, and is mostly composed of it, it has a park, but it is defined and known by its primary purpose. District 7, though its primary purpose being middle and high school education is known for many other things. In fact, one could say that the district is the melting pot of concepts that appear in several districts. It contains an underground complex, which District 22 is famous for, schools like Tokiwadai Middle  that can rival the unique schools of  District 18, and though not as fashionable or up to date, has facilities of leisure such as the Seventh Mist. Finally, what makes the district unique is that it is contains the base of the city's leader, Aleister Crowley, the Windowless Building alone marks the district as having several unique qualities to it. It would not be out-of-place to consider the District 7 as its own city.

Christmas Day Arc
On Christmas Day, the district was the site of the third part of Misaka Mikoto and Shokuhou Misaki's battle against Anna Sprengel, as she made her way towards Heaven Canceller's Hospital where Kamijou Touma was hospitalized after she infected him with St. Germain, as well as Touma's eventual battle with Anna.

Post-Handcuffs Arc
On December 29th, the district was the site of certain activities relating to the Winter Cleaning movement. Around 5.20PM, there was a collision at the South Station between the stationary Delivery Go Round and the prison train Overhunting. A number of the events following the crash and subsequent prisoner escape took place in the district. Around the same time, Aleister Crowley and Kihara Noukan visited the former site of the Windowless Building to access the information network as part of preparations for actions against Anna Sprengel.

New Year's Arc
