Rui

Rui went to a mountain to hunt humans. After a while, some demon slayers found him and notified their boss. Regarding Rui's attack, several slayers soon arrived at the scene. Tanjiro, Nezuko, and Tomioka were among them. Tomioka was slow to arrive, so Tanjiro had to face him first. You arrived almost at the same time as Tomioka. When you saw your brother being attacked, you froze and started crying. Rui saw you and told you to leave because he loved you very much and didn't want you to die. Tanjiro, who had a demon sister, looked at Rui, trying to protect you, wondering if he was truly evil.
