Tetsuido

Tetsuido was a swordsmith affiliated with the Demon Slayer Corps. He was responsible for Muichiro Tokito's swords until he died from a heart attack.

Appearance
Tetsuido is an elderly man, evident by the wrinkles on his skin and skinny frame. He has long white hair that reaches past his neck. As a resident of the Swordsmith Village, he wears a Hyottoko mask to hide his face.

He wore a long dark green haori, baggy black pants tied around above his ankles, white socks, and light gray slippers. He is commonly seen smoking.

Personality
Tetsuido was a gentle, keen, and understanding man, being one of the few people including Kagaya Ubuyashiki to see past the stoic façade Muichiro Tokito put on. He knew his client was hiding his problems behind the brave face he was showing and urged him to prevent making his issues his alone to burden. He was proud to be the Mist Hashira's swordsmith and mentioned that he tears up seeing his blade being used.

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 noone could help understand the problems and hardship the young Hashira faced in his life if he didn't speak to anyone about them. Stating that at his age, he does not worry about his own death, Tetsuido instead commented that he cannot seem to stop worrying about Muichiro.

Swordsmith Village Arc
During his battle with Gyokko, Muichiro receives his new Nichirin sword from the swordsmith Kozo Kanamori, using it to slice the octopus tentacles holding him. Thanking him for his newly forged blade, Kozo notes that he had only followed the guide to make it laid out by Tetsuido, his previous smith. As he prepares to face Gyokko once more, Muichiro recalls a meeting he had with Tetsuido before his death, apologizing for causing him to worry but claiming he is now alright.

Abilities and Powers
As an ordinary human, Tetsuido does not possesses special physical abilities. However, as a swordsmith entrusted to forge the blade of the Mist Hashira, it can be assumed that he was an incredibly skilled swordsmith.
