Toaru Majutsu no Index Wiki

Ironhide Institute of Aviation Technology (鉄身航空技術研究所付属実験空港 Tetsumi Kōkū Gijutsukenkyūsho Fuzoku Jikken Kūkō?) is a subsidiary institute of the experimental airport located next to it in School District 23.[1]


Night falls down over the institute.

Like many areas in the district, the institute is off limits to unauthorized personnel, and is heavily guarded, despite this, buses that lead to the experimental airport pass by the place, and are driven by people instead of being automated, probably to prevent any corporate spies from getting off the bus midway through. The institute specializes in the development of a short runway in Academy City.[2]

The site is apparently surrounded by a 2-meter high, mesh wire fence.[2]

The institute is the location from where Orsola Aquinas points out would be the most optimum place in Academy City to use the Croce di Pietro.[1] However, it is soon revealed that Oriana Thomson had herself be used as bait in order for Lidvia Lorenzetti to use the spiritual item to conquer the city from outside its borders, as it is well beyond what Kamijou Touma, Stiyl Magnus, and Tsuchimikado Motoharu can reach.[3]

The large open space inside the institute is the site of Touma and Stiyl's final battle against Oriana.[4]
