School District 23

District 23 (第二三学区) is a school district in the very eastern part of Academy City. It is bordered by District 6, 5, and 12 to the north,  District 18 to the west,  District 11 to the south, and Eastern Tokyo to the East.

It is the largest District in the entire city, and with good reason, for the  District is used for aeronautics, space development, and airline flights. The district is so large that to travel from one place to another requires buses instead of walking.

Primary Use
District 23 is a unique school district that completely specializes in aeronautical and astronautical engineering. Besides civilian aircraft, this place is where the fighter jets, protectors of Academy City’s airspace, and unmanned helicopters are developed. Half of the things in District 23 are runways, and satellite launch areas, with high perimeters surrounding them. The buildings, which include the control tower and the experimental areas, are rather large, several times the size of the school.

Large portions of the district are covered by flat expanses of asphalt, in order to secure as much space as possible for runways and launch sites. The skies above the district are scheduled out to the second with digital control guidance to allow countless aircraft to constantly move safely through without collisions.

Secondary Use
The district, along with District 2, are one of the districts that can be used to store weapons used in war. Not only that, the district can also apparently handle the chemical Hydrazine that is used for the City's rockets.

A direct railroad line leading from District 23 to  District 3, allows foreigners to quickly access the luxurious hotels and facilities of the district.

Security
Besides the international airport that is used for foreign tourists to arrive and depart, all the other parts on the map are just blank. This blank means that this isn’t a place to recommend for touring.

District 23 not only protects itself, but those of District 11 as well. The security robots have a special communications line with District 23. When they sound the alarm, it’s sent directly to the control area in District 23, the Air Superiority Preservation Control Center, and the Six Wings are then called in to District 11.

Despite its high security, which is at its highest during the Daihaseisai, Academy City has set up a touring route for the district, allowing tourists to ride buses and tour the district, and of course, there are places that are open for its citizens to use, like the airport.

Aside from intentional trouble, the security drones patrolling the district also act to eliminate the risks from bird strikes and windborne plastic bags.

Academy City International Airport
The International Airport is the only airport in Academy City. It was built for tourists from outside of Academy City, though seeing as Touma and Index were able to make use of it, it can be assumed that the citizens of the city can use the airport as well. The planes on the airport, specifically, the Supersonic Passenger Plane can apparently carry out direct flights to Marco Polo Airport in Venice.

A shopping center is located 1.5 kilometers from the airport, it can be assumed that it is located in the district as well.

District 23 Terminal Station
The district has only one station. It is an enormous terminal station that is connected to all roads in the district, and is comparable to an international airport.

There are 8 ordinary train lanes, 5 subway lines, 2 high speed monorail lines and 4 bus lanes at the bus terminal that's outside of the main entrance. Moreover, there are also a special delivery lane and a VIP-only lane that's not opened for ordinary people. The lines for the cargo trains go to the switchyard, where they are serviced and where the trains with a large number of containers could unload.

New Year's Arc
During martial law on January 3rd, Aleister Crowley, Anna Kingsford and Kihara Noukan went to the district, blocked off and being used as a cargo and air force base, under the concealment of anti-recognition magic and used a hotel room of the district's Science Tower as they planned their next move against Anna Sprengel and the Bridge Builders Cabal.
