C4 Connect has announced a collaboration between its mobile RPG Houchi Shoujo: Hyakka Ryouran no Moehimetachi and the currently airing TV anime Seitokai ni mo Ana wa Aru! The in-game collaboration event is set to launch on October 27, 2026 at 12:00 p.m. JST.
Student Council Members Swept Into Another World
The collaboration’s story centers on the student council members of Fujinari High School, who are suddenly transported into the world of Houchi Shoujo just as their school’s cultural festival is about to begin. Stranded in an unfamiliar land, the girls must navigate a series of chaotic incidents while pressing forward on their adventure — blending the slice-of-life school atmosphere of the anime with the fantasy setting of the game.
