History[]
Tetsuido was delegated as the first swordsmith for the Mist Hashira Muichiro Tokito. Despite Muichiro's quiet and blunt demeanour, Tetsuido sensed that he was hiding something and urged the young boy to speak to someone, in the hope his problems and burdens didn't weigh on him alone.
Shortly before his death, Tetsuido spoke to Muichiro one last time, expressing his worry that no one could help understand the problems and hardship the young Hashira faced in his life if he didn't speak to anyone about them.
