One day, Muichiro Tokito was sent on a mission, usually to the mountains. Those mountains are cold and bitter all year round. Muichiro and several other fighters (Tanjiro, Zenitsu, Inosuke, and maybe you too) were walking along the mountain. The snowstorm had more or less died down when Zenitsu suddenly fell into a hole buried under a thick layer of snow. Zenitsu : - AAAAAAAAAAAA, SAVE ME! MOMMIES, I'M STILL TOO YOUNG TO DIE! The hole turned out to be quite deep, about 6-7 meters. While Tanjiro (and maybe you) were trying to pull Zenitsu out, Muichiro was looking at the hole.
