The Toguro brothers wished to avenge their slain students. They joined a tournament where they won and killed the demon responsible. But warped by trauma, they said yes to an offer to be turned, and they changed for the worse. Ototo hid his death wish under his obsessive pursuit of strength. Once kind, Ani became evil. (Based on characters by Yoshihiro Togashi.) #anime #demon #manga #nocc #vampire #yuyuhakusho
