Kaito Hijikata

Smart but blindly self-indulgent, because of his obsession with accumulating a big-breasted harem he finished a 3-year Summon Director course in one year, so was taken under the wing of the world's premiere Summon Director champion, and placed as a lecturer in an elite academy dedicated to Prister competition.

Although a thoroughly shameless pervert, he turns out to be competent at both teaching and training Prister and their owners for the most important tournament in the world.
