Anti-Art Attachment

Anti-Art Attachment (対魔術式駆動鎧 (アンチアートアタッチメント)) is a Powered Suit developed in Academy City. As the name suggests, it is for use against magic.

Principles
This powered suit can apparently be called upon when needed and can apparently arrange itself around the user automatically. During Kihara Noukan's confrontation against Shundou Toshizou in Celestaquarium, containers that had the parts of the Powered Suit dropped around Noukan. These containers are also very powerful, easily destroying Molar Tooth, large floating spheres that can block tank shells. After landing, the containers open up and the parts of the suit, things from arms, weapons of various kinds, ammunition, and armor, float around the body like some pseudo-transforming robot. The amount of weapons that is used for this powered suit is described as in "the level of building a fortress". It can either apparently attack the target automatically or in an as of yet unknown method.

The parts and weapons of the unit can apparently be swapped out depending on the circumstances. It can weigh more than twenty tons in all, but is capable of flying, in a way which seemingly ignores gravity, using light rocket boosters which can propel it at speeds of over Mach 20.

The unit can also make use of a tactical armor-piercing drill, made of tungsten steel and running through the entire unit from front to back, dozens of meters long. Achieving speeds using the same electromagnetic acceleration as a railgun or mass driver, it produces immense destructive power through its rotation, being capable of breaking into an underground silo or destroying a military base. The drill's rotation can also be used to transmit extremely high-speed high-frequency vibrations. These vibrations can be used to convey the user's or another's will, and with the unit connected to Aleister Crowley, it can deliver his willpower in a strange form capable of killing a Magic God such as the weakened High Priest.

The Anti-Art Attachment's primary function is more an application of medical technology than military technology. A form of external cyborg attachment, it forms a link between the user and another individual, allowing the user to remotely draw on their power. Noukan makes use this connection to utilize Aleister Crowley's power and secret techniques.

Due to the fact that Kihara Noukan's role is to target beings like Ladylee Tangleroad, Fräulein Kreutune, and Aiwass, it is likely that this suit was created for his use alone. Noukan has a hangar for the Anti-Art Attachment in each of the twenty-three School Districts in Academy City.

Mental Out Arc
Kihara Noukan is first seen using the Anti-Art Attachment during his confrontation with Shundou Toshizou at the Celestaquarium, with the containers being dropped through the roof and destroying the Molar Tooth before being deployed for the execution.

St. Germain Arc
During the events instigated by St. Germain at the Dianoid, Noukan selects equipment for the unit in preparation for the upcoming confrontation with the true Gremlin. After Aleister weakens the Magic Gods, Noukan uses the unit's catapult to launch the crucified body of Zombie into their midst.

Magic God Invasion Arc
As the High Priest attempts to crash the Arrowhead Comet into Academy City, Kihara Noukan uses the unit, equipped with the tactical armor-piercing drill and connected to Aleister, to deliver Aleister's willpower in a form which kills the Magic God. Noukan and the Anti-Art Attachment then destroy the comet before it can impact the city, meeting it in a collision at over Mach 20.

World Rejecter Arc
That night, Aleister has the Anti-Art Attachment overhauled and prepared for Noukan's battle against Kamisato Kakeru, though he implies in his conversation with Noukan that he wouldn't be able to win with it. Later, Noukan uses it during the confrontation, but due to its connection with Aleister and his conflicting desires, it proves a valid target for World Rejecter and is subsequently erased by it.
