Renoir

The Sixth-Ranked School Youkai. Renoir is a tsukumogami (a youkai born from a very old inanimate object) that haunts paintings in the art room. This being an era when no one has any room in their heart for showing interest in paintings, Renoir finds itself sleeping a lot. Renoir very rarely interferes with the other school youkai's hunts, so they tend to dote on it like a younger sibling.

Spoiler

Renoir is a boy. He is often mistaken for a female due to his lack of masculine features. He's usually fast asleep, but once in a while, he will wake up and pull a human into one of the paintings.
