Satan

Satan is a little creature in the series Grimoire of Fantasy

Status
Satan is a deceased demon who used to be a ruler of Hell. During the two chapters of the first story, he seems like an enjoyable creature until he joined plans with Lilith who is now betraying her occupation as a Priest in Heaven.

Lilith hasn't been spotted as a bad person to Karin and the others and they seem all calm even when some of them had suspicions on each other.
