Headmaster
From Puyo Nexus Wiki
Headmaster is the principal of Arle's school in Madou Monogatari: Hanamaru Dai Youchienji. In one point of the game he is possessed by Devil and freezes everyone in the school into statues except Arle. When Devil escapes, he rewards Arle with the Magical Dictionary, which can be used to read gold plaques.
