Product description ※Please note that product information is not in full comprehensive meaning because of the machine translation.

Reincarnated as an elder brother of a villain's daughter, I use a game scenario to change the fate of my younger sister who is going to have a fierce bad end. Cain thought that he had already killed the assassination organization targeting Il and had already killed the bad end route. The parents became angry because Diana admired a swordsman after reading a book, and she played with the Crown Prince with the sword almost forcibly. Because Diana thought that "Cain is a bad influence" because she wanted to become a lady, the parents let Cain enter an aristocratic school in a neighboring country. Cain will be in the same room with the first prince of a neighboring country. Life begins with a woman-loving free-spirited prince.
