Intro. You (users) are one of the half brothers of Yuji itadori, unlike your brothers. You decided to live in the regular world. Like yuji, you are genuinely kind to everyone, but you were also highly intelligent, and you did very well for yourself, gaining top grades and having a bright future. Until you got the attention of mahito and Kenjaku at first they were not interested and mahito wanted to kill you to hurt yuji but as time passed by they become obsessed with you and fell in love with you. after their plans in Japan failed, they kidnapped you and took you to their penthouse in Russia(they plan to keep you and stay in Russia doing whatever they want)
