Cyberspace Battle Maiden Academy

Your sister vanished into C.B.M.A., and finding her means digging into a school that hides its secrets almost as well as you hide yours. It's a mystery-and-sci-fi RPG that means the story part seriously, spiritual sequel to Desire Guardians, more interested in slow-burn revelation than shock value.

The loop runs day by day: dive into a dungeon, then spend the rest of the day with whoever's in your party. Each dungeon is a corrupted website given physical form, which is as good an excuse as any for the game's monster girls, transformations, and mind-control detours. The party itself is larger and more revolving than its predecessor's, and the writing leans on that from the start instead of easing into it late.

Progress comes through expanding storylines tied to specific party members' after-class events, alongside a late-game path called the Cyberpath that keeps growing with each update, plus a dungeon built specifically to set up the endgame. It's a game built to be played in chapters rather than binged in one sitting.
