As ufotable's ongoing television rebroadcast of Demon Slayer: Kimetsu no Yaiba progresses, Episode 25, titled Tsuguko Kanao Tsuyuri, brings fans right back to the grueling rehabilitation training at the Butterfly Mansion. With Tanjiro Kamado pushing his body to master Total Concentration breathing even in his sleep, the episode balances intense physical growth with trademark comedic character dynamics before the monumental shift toward the Mugen Train arc.
Originally created by Koyoharu Gotouge in Weekly Shonen Jump, the manga has sold over 220 million copies, establishing a modern dark-fantasy standard. Studio ufotable has continuously elevated the source material since the 2019 Tanjiro Kamado, Unwavering Resolve Arc, leading up to the monumental Infinity Castle theatrical trilogy. Amidst the intense training sessions, Episode 25 highlights Tanjiro's unwavering determination alongside Zenitsu and Inosuke's reluctant struggles with their own regimens under the watchful, delightfully provocative guidance of Insect Hashira Shinobu Kocho.
