A story where the protagonist is a male villain's daughter!? Reincarnated as 'Leon' in a poor baron's family, he finds himself living in the world of 'that otome game' he played in his previous life. This is a fantasy world where the land floats and airships traverse the skies. However, Leon cannot enjoy it honestly because he knows it is the world of that otome game with its vague settings. In this world, Leon is reborn as a 'mob,' a character without a name in the game. In the academy, it is normal for girls to have personal servants, who are subhuman slaves. Boys are not allowed to have subhuman companions and always struggle in the dating scene. However, the male nobles who are the targets of the otome game are always surrounded and pampered by girls. Seeing this, Leon's anger grows at the unfair circumstances. Believing he has been reincarnated into the vague world of that otome game, Leon uses his game knowledge and underhanded tactics to overcome various difficulties to secure a peaceful future! However, that was not the case. * Already published as a book by GC Novels. 13 volumes in total [Completed] Audio books are also available!
