Bible Black Vol.6バイブルブラック

To have all the sex and power he could ever want, Minase made a pact with the demonic university nurse, Miss Kitami. Through their special induction ceremonies, the two converted Shiraki, the most popular girl in school, Miss Takashiro, the art teacher, and the three girls from the school's magic club. Now Kitami has a new plan, to take all these girls and go after Imari, Minase's neighbor and childhood friend. Minase must either help Kitami convert Imari with a ritual orgy or fight the dark lust growing inside of him and protect her.
