Assassination Classroom has announced new opening (OP) and ending (ED) songs and artists for its 10th anniversary rebroadcast. This will be the first of three major projects (or ‘missions’) for the 10th anniversary celebration, while the other two are yet to be announced. It will include the rebroadcast of all 47 episodes from April 2025.
The new opening theme song will be “Kiiro Shingo” (“Caution”) by Sora Tomonari, while the new ending song will be “Tsuki no Fune” (“moonship”) by ATARAYO. Both of the artists commented on their upcoming songs:
New Assassination Classroom 10th Anniversary Rebroadcast OP & ED Artists Comments
Sora Tomonari
I am Sora Tomonari, and I am honored to be in charge of the new OP for the TV anime Assassination Classroom. This series was my absolute favorite Jump work during my childhood, so when I received the offer, I was overjoyed. As a proud graduate of Class 3-E who deeply loves Koro-sensei, I am truly happy to be able to contribute to this beloved series through music!

ATARAYO
Ever since I was a student, I have loved Assassination Classroom. I enjoyed both the manga and the anime adaptation, and it became an important part of my youth. I feel truly honored to be involved in this way—thank you so much.
“Tsuki no Fune” is a song that depicts a person’s growth and inner strength. I hope that everyone watching the anime will enjoy listening to it as well.

Crunchyroll streams the anime, describing the story:
Forget about homework and pop quizzes. The students of Class 3E have a far more important assignment: kill their teacher before the end of the year! A tentacle-d sensei that moves at Mach 20 is out to conquer the classroom after destroying seventy percent of the moon. In addition to reading, writing, and arithmetic, the murderous monster behind the lectern will teach his students everything he knows about the assassination game. Should some eager beaver prove to be a quick study in killing, he or she will save Earth from extinction – and collect a hefty reward.
The series also has two live-action movies: Assassination Classroom (2015) and Assassination Classroom: Graduation (2016).
