The Magician's Academy
MA Project
まかでみWAっしょい!
Magician's Academy revolves around Takuto Hasegawa, who attends a magic academy that is not marked on any map. During a summoning spell exam, he accidentally creates a girl named Tanarotte, who happens to hold enough magical power to destroy his country, but fortunately Tanarotte professes undying loyalty (and love) to her "creator."
