COSM-GAME BLUE REFLECTION Quartet
BLUE REFLECTION Quartet is a single-player RPG collection that brings four stories from the BLUE REFLECTION series together in one release. Players can experience an enhanced version of BLUE REFLECTION, a playable retelling of BLUE REFLECTION: RAY, a rebuilt BLUE REFLECTION: SUN, and an expanded BLUE REFLECTION: Second Light. Across the collection, students form bonds, explore worlds shaped by emotions and memories, and fight supernatural threats through several party-based battle systems. A shared Reference database and Gallery connect events and character relationships across the series, while features such as higher-resolution textures, faster movement, autosave, and event fast-forwarding modernize the included works.

Platforms and availability
BLUE REFLECTION Quartet supports PC, PlayStation 5, Nintendo Switch, and Nintendo Switch 2. The PlayStation 5 version supports offline single-player play. Nintendo Switch and Nintendo Switch 2 are separate products with the same game content, but save data and additional content are not compatible between the two versions, and the Nintendo Switch edition cannot be upgraded to the Nintendo Switch 2 edition.
Gameplay and setting
BLUE REFLECTION Quartet combines four different experiences rather than presenting one continuous campaign. BLUE REFLECTION follows Hinako as she forms bonds, gathers emotional Fragments, and fights supernatural beings called Sephira. RAY lets Hiori and Ruka explore the Common, a world formed from the collective human unconscious, while collecting Memory Shards that reveal its story. SUN rebuilds its main story using the battle systems of Second Light and adds 24 character events. Second Light combines exploration of the otherworldly Heartscape with relationship building and party battles, while Quartet adds eight battle characters from RAY and SUN. The Reference database connects major events and character relationships across the complete series.
