Nasara

An intellectual life form that suddenly appeared in the Demon Realm. It used to wander the Demon Realm, swallowing matter or other life forms on instinct and absorbing their knowledge. But now she seems to lead a leisurely life as a member of a detective agency in Yomihara.

Though she has assumed the form of a human woman, her body is composed of countless tentacles capable of transforming into various shapes. She possesses little in the way of emotions as a living creature and does not show hostility toward others unless they are enemies or prey. However, it is said that once she is provoked, she retaliates and continues her assault until her opponent is utterly destroyed.
