Sabito

Sabito was a former apprentice of Urokodaki Sakonji.

Appearance
Sabito is described as wearing a colorful jacket, with peach colored hair, and a visible scar by his mouth. He is also seen wearing a fox mask with a scar located by mouth similar to Sabito's scar.

It is later revealed that Sabito's spirit was present during Tanjirou's training, instead of his physical state.

Personality
Sabito is seen as a ruthless mentor, acting unnecessarily harsh towards Tanjirou as he trained for the Final Selection. However, after Tanjirou succeeded in dividing the boulder, Sabito can be seen smiling with pride at his accomplishment.

History
Sabito was an orphan who was sheltered by Urokodaki, whom trained him to become a demon slayer. However when he went to compete in the Final Selection, he was tragically killed by a vengeful demon which was entrapped on Mt. Fujikasane by Urokodaki.
