“Monster Strike” (Monst), and the hit anime series “Bocchi the Rock!” are set to collaborate for the first time.

“Bocchi the Rock!” has garnered immense popularity since its debut, with its charming portrayal of Hitori Goto, an introverted high school girl who dreams of joining a band, and her journey with Kessoku Band.

“Monster Strike,” a behemoth in the mobile gaming scene, is known for its strategic gameplay and frequent collaborations with popular anime and manga series and brands, which include a recent team up with potato chip manufacturer Calbee.
