After getting into Hell, a sexy deviless, instead of taking your soul, offers you to work for her, seducing girls to take them to her. She will send you to a strange city where girls arrive unwillingly, desperately looking for a way out. Will you follow the devil's lead or help the famous girls in trouble? In any case, you must become the principal of the “Waifu Slut School” and making your own choices, decide your fate and the fate of your waifu.
