C4 Connect has officially announced a collaborative crossover between its popular smartphone idle RPG Houchi Shoujo and the currently airing TV anime Seitokai ni mo Ana wa Aru!. The special in-game event is scheduled to launch on October 27, 2026, bringing an unexpected genre blend to mobile screens.
In this narrative crossover, the student council members are suddenly whisked away into the world of Houchi Shoujo right on the eve of their school festival. Players will guide the characters through backstage mishaps and surreal obstacles in an alternate realm. Ahead of the official launch, a pre-registration campaign kicked off on October 20, offering users a chance to secure up to ten collaboration gacha tickets alongside other physical prizes like MetaPad devices.
Broadcast and Franchise Background
In addition to the in-game quests, a special TV commercial celebrating the collaboration is set to air across Japanese networks starting October 31, 2026. The pairing brings together C4 Connect's long-running idle RPG franchise, active since 2017, and Muchimaro's hit romantic comedy manga serialized in Kodansha's Weekly Shonen Magazine.
