School District 12

School District 12 (第一二学区) is the easternmost School District of Academy City. It is bordered to the west by School District 19, School District 6, and School District 23. To the east, it is bordered by Eastern Tokyo, with its entire eastern side surrounded by Academy City's wall. The district's primary feature is its collection of schools dealing with theology.

Principles
The district's focus is religious facilities, occult studies and theology schools, from a scientific approach and perspective. Although the district is known for its collection of theology schools, rather than believing in gods, the idea behind them is to research why humans believe in gods and what is needed to keep people in the special psychological state known as 'belief' in the long-term. Most of the research in the district falls under the fields of philosophy, psychology and architecture. The district is home to the Occult Denial Society (オカルト否定学会), Academy City's analysis of all things unscientific and supernatural.

While the district has many reconstructions of religious facilities, some with elaborate and detailed constructions, they are shallow recreations from a scientific perspective, with no magical symbols or anything that would matter to the magic side. Rather than asking why people believe in Shinto fortune slips, it would instead be asked what psychological conditions lead people to pay money for them when the outcomes are apparently just determined by random chance, with some buildings' reconstructions nothing more than a model on the cycles and patterns needed to efficiently bring people in and take their money.

Land is something which can't be spared in Academy City and as such, it cannot have big shrines and temples sprawling out along the ground like in other places. Instead, most of the buildings in the district are high-rise skyscrapers with multiple floors and no interior walls, providing more space than the average school campus. Most of the religious facilities in the district are housed inside these skyscrapers' floors - for example, a huge temple garden could be built on one of these floors and even though it is all indoors, one could meditate under a waterfall. These buildings do not just contain one type of religious or mythological facility, with a system of openings for people (e.g. university research teams) wanting a type of temple or cathedral similar to that of leasing rooms in a multi-tenant building. It would not be unusual in these buildings for the ground floor to hold a discount store while the second floor houses a church.

Although most of the district's religious facilities are held in or converted from high-rise buildings, there are constructions in the open as well. Lined up in between the concrete and glass skyscrapers rising like bamboo shoots, there are Greek-style temples (with color patterns applied to a temple with project mapping - likely for researching the theory that the Parthenon was not originally white), giant pyramids, five-story pagodas stone monuments and statues of goddesses, a river with naturally decomposing origami dolls floating down it rather than fallen leaves or flower petals, and elevated streets closed to traffic, along which herds of deer might wander. The place has been described as feeling more like a theme park with replicas of famous tourist locations around the world than a research institute for mythology and religion. The streets lined with various religious facilities give a multi-cultural feeling to it.

Ichihanaran Festival Arc
Silvia, Brunhild Eiktobel, and Leivinia Birdway visited the district during the Ichihanaransai. They complained about district's unpleasant structure.

New Year's Arc
On January 1st, many residents of Academy City came to District 12 as part of their New Year's shrine visits. At that time, the Bridge Builders Cabal had also managed to set up a consulate in the district via its acquisition of the Condroniard Republic. Having greeted Touma on New Year's Day, Alice invited him and his group to her new 'secret base' on January 2nd.

Astral Buddy Arc
After retrieving Yuuri Senya's true body, Yuuri Senya, Hokaze Junko, and Shokuhou Misaki visited Toomine Kanari's grave in the district.
