Fans were delighted by the rare sight of Master Ubuyashiki, who is usually serene, openly expressing such heartfelt joy. Reactions included, "I love this scene where Master Ubuyashiki wears his emotion on his sleeve," "Of course you'd get overexcited when something that hasn't changed in 100 years finally does," and "This is probably the most emotionally high-strung moment for Ubuyashiki in the entire series."

The "Demon Slayer: Kimetsu no Yaiba" anime series is based on the manga of the same name by Koyoharu Gotoge, which was serialized in Weekly Shonen Jump from 2016 to 2020. Set in the Taisho era, the story follows a boy, Tanjiro Kamado, who fights against demons after his family is slaughtered.

The TV anime "Demon Slayer: Kimetsu no Yaiba Tanjiro Kamado, Unwavering Resolve Arc," which began airing in April 2019, quickly garnered attention, and its sequel, "Demon Slayer -Kimetsu no Yaiba- The Movie: Mugen Train," surpassed 50 billion yen in worldwide box office revenue. Today, the total global circulation of the original manga has reached 220 million copies, making it one of the best-selling and most iconic works in the history of Japanese manga and anime.

The TV anime has aired sequels after the initial "Tanjiro Kamado, Unwavering Resolve Arc," including "Entertainment District Arc," "Swordsmith Village Arc," and "Hashira Training Arc," while the final episodes are being adapted as a trilogy under the title "Demon Slayer: Kimetsu No Yaiba The Movie: Infinity Castle." The first installment, "Demon Slayer: Kimetsu No Yaiba The Movie: Infinity Castle - Part 1 Akaza's Return," which has been screening since July 18, 2025, has earned over 31.4 billion yen in box office revenue within its first 52 days.
