Tengen Uzui, the former Sound Hashira, is a fan-favorite character in Demon Slayer, which has been revisited in the latest episode of the anime, Demon Slayer: To The Hashira Training. While Demon Slayer fans are eagerly waiting for the next episode, they have already seen the preview of what the season will offer in the movie itself.
Although Episode 3 of Demon Slayer: To The Hashira Training was mostly filler, fans aren’t complaining since they get to see one of their favorite Hashiras before he retires. The episode titled “Fully Recovered Tanjiro Joins the Hashira Training!!” is exactly what it says on the label. It depicts a recently recovered Tanjiro ready to swing his sword.

It also shows Tengen Uzui in action before he retires from the Demon Slayer Corps. Although Tengen will make appearances in Season 4 of Demon Slayer, it will be limited and brief. Hence, fans are preparing to say goodbye to a well-loved character.
Episode 3 Was Like a Final Farewell To Tengen Uzui

“Fully Recovered Tanjiro Joins the Hashira Training!!” honors retiring Hashira Tengen Uzui, who most recently had a significant part during Demon Slayer’s Entertainment District Arc, in addition to Tanjiro’s unwavering battle spirit. This is never a bad thing, and in their first season, Uzui and his three wives were very interesting characters.
Even though Uzui is no longer employed by the Hashira department, he is nonetheless skilled in training the demon slayers until they bleed. While the Demon Slayer Corps continues to pool resources, Uzui fervently trains the masses.

Will Fans Get To See Tengen Uzui Again?

In short, yes, fans might get to see cameo appearances from Tengen Uzui in Season 4, but it will be very brief. Considering that Tengen is not a major character anymore, it will be a rather good surprise if he does feature in the next episodes.
Episode 3 of Season 4 takes a breather from the fast-paced nature of the previous seasons and puts Tanjiro into training shoes. The best part of the episode is undoubtedly when Tengen mock-battles his trainees and shows off his amazing powers. So, in the end, Tengen Uzui still scores!
