The third brother of the family. He is the son of the demon Satan and represents the corresponding sin of Wrath.
Sanen takes on the role of the constantly angry class president among the sisters. She is known for giving out rapid-fire scoldings, which makes the other sisters scared of her. Because of this, no one is willing to talk back to her, which means she is surprisingly lonely. She'll sometimes intentionally try to do things that should anger the other sisters, but they never scold her back, which leaves her even more lonely.
