Macademi Wasshoi!

Takuto Hasegawa studies at a magical academy hidden from ordinary society. During a summoning examination, a mistake that should have ended in failure instead produces Tanarot, a mysterious girl whose enormous magical power is wildly out of proportion with her innocent appearance.

Tanarot immediately declares absolute loyalty to Takuto, turning his already unusual school life into chaos he can barely manage. Gods, demons, and fellow students are pulled into one absurd conflict after another while Takuto tries to understand what Tanarot really is and why she possesses power no one can properly measure. Nearly every attempt to contain the problem only creates a larger one.
