Yuushi

ユウシ

Daki's foster father and utter lunatic. He treats Daki more like a tool than a daughter. Able to control bugs as his daughter can, he appears to be a sort of demon, once trying to eat Chikei's desires. Yuushi is constantly getting in Qwan's way of consuming the 'Essential Arts of Peace'. [Spoiler] Later, it revealed that his true form is a spider demon. He took interest of Daki's power and took her from Bug Forest (by taking advantage of Touda's favor to cure Daki's illness ).
