Tokitou no Chichi

Muichirou's father is kind, optimistic, hardworking, and devoted to his family. He believes that helping others ultimately benefits oneself as well, an idea that remains buried in Muichirou Tokitou's memory after his amnesia.

His compassion can override concern for his own safety. When his wife becomes seriously ill, he is determined to obtain medicine for her despite dangerous conditions outside.

His personality contrasts strongly with Yuuichirou Tokitou's later pessimism. Yuuichirou interprets his father's choices as reckless, while Muichirou remembers the kindness motivating them.

Muichirou's father is an ordinary human and has no established Breathing Style or supernatural abilities.

He works as a woodcutter in the mountains, requiring the physical endurance and practical skills needed to support a family in an isolated environment.

Muichirou's father appears through his son's recovered childhood memories during the Swordsmith Village Arc.

His words become important when Tanjiro Kamado tells Muichirou that helping others can eventually be good for oneself. The statement feels familiar because Muichirou's father once expressed the same belief.

When his wife becomes ill, he goes out during dangerous weather to obtain medicinal herbs. He falls from a cliff and dies, leaving the twins with their mother, who dies soon afterward from her illness. The losses contribute to the circumstances that leave Muichirou and Yuuichirou alone together.

Muichirou Tokitou is his younger twin son. Muichirou inherits his father's compassionate disposition and remembers his words during the Swordsmith Village battle.

Yuuichirou Tokitou is his older twin son. Yuuichirou later criticizes his father's decision to venture outside in dangerous conditions, viewing it as avoidable recklessness.

Tokitou no Haha is his wife. His attempt to obtain medicine for her during her illness leads to his fatal fall from a cliff.

Tanjiro Kamado reminds Muichirou of his father because of both his red eyes and his compassionate words.
