About the book: 2019 / I am the thirteenth witch in the family and a mediocre adept. He is the lord of Hell. How did I manage to imprison him in a magic circle? Don't know. Demons are dangerous seducers, and I stood in his way. He put his mark on my body. If Asmodeus finds me, he will come for my virginity, and then I will be his toy, a bottomless source of energy. My only chance to survive is to make the depraved demon fall in love with me and subjugate me before he takes away my innocence. To hunt a demon, I go to study at the highest magical academy for gifted witches. After all, where there are sheep there is a wolf. But which student is a false adept and a true pervert? For the sake of my own freedom, I must find out. I have a faithful familiar and a magic book with me. Ready for demon selection!
