One day, a high school student, Minase Reito, who had been living in modern Japan, is suddenly reincarnated in another world as Lars Feldia, the son of a count. In addition to the unfamiliar situation of being reincarnated, Reito is bothered by the fact that the boy to whom he is reincarnated is a bad boy, and is hated by everyone. Nevertheless, as he lives his life as Lars, the number of people who are important to him increases, and he feels the need to develop into a fine person as Lars. Even though he is hated and feels malice every day, Reito resists and lives against irrationality in his new world. This is a otherworldly fantasy about a boy who is reincarnated as a hatred child. *Although the title mentions “villain”, the world in the story is not the same as the world in the novel, manga or game. We apologise for any title deception. Also, the early part of the story is as the title and synopsis suggest, but from the middle of the story onwards, it will be a simple royal road otherworldly fantasy.
