The third season of Demon Slayer is currently airing worldwide, and the new episodes provide us with more details about Tanjirō’s adventures in the Swordsmith Village. The season has also introduced us to some new characters, those living in the famous Swordsmith Village. One of them is an old swordsmith connected to Muichirō, the Mist Hashira, whose name is Tetsuido and who appeared only as a flashback. In this article, we are going to tell you who Tetsuido is and what happened to the old swordsmith in the story of the Demon Slayer manga and anime.

Tetsuido was a supportive character from the Demon Slayer manga and anime who appeared briefly in a flashback scene during the Swordsmith Village Arc. He was an old and experienced swordsmith who made blades for Muichirō Tokitō, the Mist Hashira until he died from a heart attack in his old age. He worried about Muichirō, and aside from creating his swords, he also acted as a friend and often talked to him.

The rest of this article will focus on Tetsuido and his fate in the Demon Slayer: Kimetsu no Yaiba series. Tetsuido was one of the most interesting additions to the Demon Slayer lore, and it only makes sense that the fans want to know what happened to this kid, so we have decided to compose this article. This article will contain some spoilers from the Demon Slayer: Kimetsu no Yaiba manga, so be careful how you approach it.

Tetsuido helped Muichirō in more ways than one

The story actually needs an introduction so that you know how Tetsuido even got the chance to appear. Namely, when Gyokko appeared in the Swordsmith Village and showed off his morbid human sculpture, after having commented how he disliked the taste of swordsmiths, he targeted Kotetsu and Kozo next.

Still, Muichirō Tokitō stepped in front of him to protect the two swordsmiths. Gyokko then started his fight with Muichirō, but he soon managed to trap him in his Water Prison Pot, after which he targeted Hotaru, who was, at the same time, working on restoring Yoriichi’s blade for Tanjirō, as he had promised after Tanjirō found the blade in the Yoriichi Type Zero doll.

Hotaru was so concentrated on repairing the blade, in fact, that he completely ignored Gyokko’s and Hantengu’s attack on the village. Gyokko pestered him all the time. He even attacked and injured him severely, but despite his mask broken, his body injured, and losing one of his eyes, Hotaru kept working on the blade until he managed to deliver it to Tanjirō.

And while Kozo tried to protect Hotaru, Kotetsu showed his bravery when he went for Gyokko’s pot to free Muichirō, who was on the verge of death. It was, indeed, thanks to Kotetsu’s bravery that Muichirō managed to free himself. He also managed to awaken his Demon Slayer Mark in the process, and this moment in the story gave us a glimpse into Muichirō’s past.

Namely, Muichirō had a memory problem we have already talked about; due to the trauma he had experienced as a child, especially witnessing his twin brother’s death at the hands of a Demon, Muichirō got amnesia and was lightheaded for a long time. As Kotetsu was freeing him from Gyokko’s water prison, we received an insight into his childhood that showed us what happened to him and his brother back then.

And while the story of the Tokitō twins is certainly interesting, we have already written about it, so we won’t be repeating ourselves. What is important here is what followed after Muichirō’s release.

Namely, the Mist Hashira then engaged the Upper-Rank Five in combat, but Gyokko was still a tough nut to crack. The Demon was surprised that Muichirō managed to escape his Blood Demon Art, but his focus was still on Haganezuka, whose determination to finish restoring Yoriichi’s blade both angered him and fascinated him; this happened even though Muichirō had awakened his Demon Slayer Mark, which should have been an obvious warning sign for Gyokko.

As the Demon continued attacking the swordsmiths and Muichirō, Kozo Kanamori delivered to Muichirō his mended Nichirin Sword, where the real fight began.

With his new blade, Muichirō remembered yet another thing from his past now that his amnesia had been cured. He remembered his early days as a Demon Slayer and his earlier visits to the village. Namely, it is known that each Demon Slayer is assigned a particular swordsmith who is in charge of creating and repairing their swords; the swordsmith can change (as Haganezuka’s past shows), but this is not common.

In Muichirō’s case, the swordsmith in question was Tetsuido. Now, Tetsuido was, when we saw him, a very old swordsmith with a lot of experience, we assume. He also seemed to be quite wise and was fond of Muichirō, whose troubles he knew about. Tetsuido was worried about Muichirō because of the amnesia that had been troubling him and because he thought the young Hashira was pushing himself too hard.

Still, he was there for him, and aside from forging his blade, he also helped him by talking to him and giving him advice, which is why Muichirō cared for him as well and respected him.

When Muichirō came to the village in the current arc, we discovered that Tetsuido had died of a heart attack, which is not surprising, seeing how old he was. This saddened Muichirō, but during his fight with Gyokko, he expressed his gratitude to his old swordsmith and thanked Kanamori for giving him a new, powerful blade.

Sadly, we know nothing else about Tetsuido as his story was presented only to further expand Muichirō’s story, but he was an important character and a character who had a profound influence on Muichirō, which is why he absolutely deserved this short article in our opinion.
