Fujishiro Shark

Initially summoned by Sun's father to target Nagasumi during a pivotal family visit, this Seto Group member eventually adopts the role of Nagasumi's P.E. instructor. Driven by the grim belief that consuming the source of chaos resolves any conflict, he frequently attempts to eat the protagonist to hasten everyone's return home. Though often found napping, this character can shift between a human form, a mere shark head, or even a full shark.
