Full Comments from the Cast

Seeker: Umehara Yuuichirou

It is a great honor to be involved with the historic Ansatsu Kyoushitsu. Recording with my senpai (senior colleagues) as one of the assassins was a truly enjoyable experience. There were many comedy scenes where I had to hold back laughter during recording, and I hope that energy and momentum will reach all of you. Seeker, the character I played, is an assassin yet possesses a charming side, so I believe he will surely be perceived as captivating. Please look forward to Gekijouban “Ansatsu Kyoushitsu” Minna no Jikan.

Futoshi: Yamaguchi Kappei

I participated as Futoshi. Recording alongside the assassin team as a regular at the izakaya “Azusa” was a genuinely fun time. The pacing and atmosphere of our exchanges were fantastic, and it felt like it was over in a flash! I’m truly looking forward to seeing the final result.

Mario: Yamaji Kazuhiro

When I heard I’d be playing a character targeting Korosensei, I confidently thought, “Leave it to me!” But as I performed, it seems my heart was the first to be shot through. That teacher effortlessly dodges both bullets and scripts—it’s as if he’s aiming for laughter right from beyond the screen. 10 years later, I thought the target’s location might have changed… but no, he’s still right in the middle of the readers’ hearts. Ansatsu Kyoushitsu is truly a terrifying work. A celebratory cannon (or rather, celebratory gun), *Don*!

Chanta: Toochi Hiroki

This is Toochi Hiroki, and I had the pleasure of participating as Chanta in Gekijouban “Ansatsu Kyoushitsu” Minna no Jikan. For such a popular work as Ansatsu Kyoushitsu, and a theatrical film at that! I approached the recording with great enthusiasm. My character is one of the assassins targeting Korosensei, and the other voice actors, my companions, were truly splendid! It was incredibly fun. Everyone, please look forward to it!

Sengoku: Inada Tetsu

I’ve had the opportunity to appear in two previous anime adaptations of Matsui Yuusei-sensei’s works, so I vaguely thought it would be great to appear in Ansatsu Kyoushitsu too—a dream I thought unreachable, but it came true in an unexpected way! Now that this has happened, I’d certainly love to appear in Matsui Yuusei-sensei’s next anime adaptation as well. But before thinking about the future, first and foremost: please watch this Ansatsu Kyoushitsu!

Comment on the Third Ending Theme for the Re-broadcasting TV Anime “Ansatsu Kyoushitsu”: Kaeri no Kai “Spica”

This song was created with the wish to depict not only ‘graduation’ and ‘parting’ as its core themes, but also the hope that lies beyond. Spica is one of the brightest first-magnitude stars in the night sky, forming part of the Spring Triangle. We hope this song will shine like a beacon, guiding people who experience various partings in spring to meet again.
