Aleister Crowley

Aleister Crowley (アレイスター＝クロウリー Areisutā Kurōrī?) (12 October 1875–1 December 1947 officially), born Edward Alexander Crowley (エドワード=アレクサンダー=クロウリー Edowādo Arekusandā Kurōrī), is the founder, leader, and General Superintendent (統括理事長 Toukatsu Rijichou?, lit. "General Superintendent") of Academy City who holds power greater than that of the Board of Directors. He is referred to as the greatest magician in history and magic's greatest embarrassment, who had quit magic in order to analyze science and technology. He is the de facto leader of the Science Side as the ruler of Academy City, and his actions and plans continually subvert the magic side and often moves the actions of the protagonists.

He resides in the mysterious Windowless Building, floating upside down and connected to wires, inside a tube of red liquid.
