Hand Demon

Ruthless, very sadistic, has a big hatred for Sakonji Urokodaki and promises to kill Sakonji's apprentices for revenge after being defeated and trapped in the wisteria-riddled Mount Fujikasane by him. Also has a deep fear of death, but still has a sense of gratitude. Also tends to keep track of time. Anime appearance: Demon Slayer Kimetsu no Yaiba
