Sabito

Sabito was a skilled and talented Demon slayer who was trained under the guidance of Sakonji Urokodaki (a former Demon Slayer Corps member and the former water Hashira) along with Makomo on Mt. Fujikasane. During his final selection, Sabito defeated many demons until he came across a uniquely powerful demon known as the Hand Demon, who had killed many of Sabito's fellow demon slayers. Sabito along with Makomo were also tragically killed during the battle with the Hand Demon, sacrificing themselves, so their peers could escape. After the incident, their souls could not rest because of their failed attempt to defeat the demon and also Sakonji's sadness at losing the two talented Demon Slayers he had trained.
