Izumo

A brilliant philosopher with a deep love for the natural world, this dual-natured half-demon transforms into the powerful Gyuo once night falls. Possessing the rare expertise required to craft Shikon no Tama, he becomes a target for a group of frog-demons seeking to manufacture counterfeit jewels. To replicate the true gems' potency, he explains that one must harvest specific human souls representing courage, friendship, wisdom, and love, leading him into a complex web of deception.
