Lilim is a collective name for the daughters of the demon lord. Unlike ordinary succubi, they not only feed on male energy to maintain their existence, but also look for a partner for their whole life among people. However, none of the living men can live with her for a year, since the essence of lilim draws out all the life force. Our heroine decided to challenge nature and loneliness by creating a superman with whom she can pass the infinity, because he will generate for her an unimaginable amount of energy than she can absorb.
