Quartet is a series collection, not a single campaign. Two full RPGs sit beside rebuilt versions of RAY and SUN so the whole mixed-media project can be played in one place.
Hinako Shirai, an injured former ballerina, accepts Reflector powers and journeys into the Common where emotions take physical form.
School bonds, Fragments, and turn-based Reflector battles.
The foundation for series terminology, world rules, and recurring characters.
Hiori Hirahara and Ruka Hanari explore Reflector conflict inside the Common in a condensed 3D retelling of the anime story.
Character-driven chapters, Memory Shards, and emotional confrontations.
Rebuilt with new prologue/epilogue material so it sits cleanly beside the games.
A squad fights ash corruption and Testa creatures in a world where young women known as the Eroded are transformed.
Party formation, school events, and Second Light-style battles.
The discontinued live service becomes a self-contained console scenario with 24 story events.
Ao Hoshizaki awakens at a school surrounded by water, where girls with lost memories explore Heartscapes and search for a way home.
Real-time combat, dates, crafting, facilities, and bonding.
The crossover finale — Quartet adds eight party members from RAY and SUN.
