Sakurazaka46 and Yoshihiro Togashi's Hunter × Hunter have teamed up for a special collaboration music video. 

The video was created as the 57th installment of JUMP MV, a collaboration project that pairs Weekly Shonen Jump manga series with artists from Sony Music Group. It features Sakurazaka46's "Unhappy birthday Koubun," originally released as the group's 13th single in October 2025.
