After an unexpected attack by Demon at the Dark Forest, Corina, a young NEKO maid, is saved by a succubus. Corina reaches Deadwood Village and looks for a job at the Devil's Deen Hotel. There she meets the owner: Carmilla, the succubus that saved her. She also needs a helper.
Alone and feeling bad about her community kicking her out for being a NEKO, Corina accepts to make a pact with the succubus. Now, both have 30 days to Collect Fragments of Desire and Create Imprisoned Souls to pay the evil Demon Belzebuth.
Will both of them be capable of seducing a lot of people while managing a hotel? Or will they be forced to pay the dept by being eternal sex slaves for Belzebuth?
