Blue Reflection is a role-playing game, which follows a day cycle: in the morning, the player character goes to school, and sometimes meets other students on the way. Scenes occur during school, some of which involve questions from the player character's classmates, which affect their relationship to the player character depending on the player's answers;[1] close friendships with characters enables additional support benefits during battles, and affects their attitudes towards the player during story sequences.[2] The player can also interact with characters by messaging them through an in-game mobile app, which also allows the player to view character profiles and play minigames. After school, the player is allowed to move around freely; they can choose between various activities, including spending time with the classmates and creating items. After the player is done for the day, their character returns home, and the day ends with her going to sleep.[1]
The player can also try to solve classmates' problems during their free time.[1] The cause for their problems sometimes reside outside the real world, in the Other World; by visiting it, the player can seek out emotion fragments, which cause defects in the real world. After finding the fragments and overcoming challenges in the Other World, the player learns about the thoughts of the character they're helping, is returned to the real world, and receives reward items and fragments.[3] Different missions include different rewards; some give the player growth points, which the player can invest in their characters' attack, defense, support, or technic stats, making them stronger and teaching them new skills. The fragments the player acquires can be equipped to the characters' skills, giving the skills additional effects. In addition to the rewards, some missions give the player evaluation points; the story progresses when the player has acquired enough of them.[4]
While exploring the Other World, the player sometimes encounters monsters, leading to a battle,[3] wherein the three characters in the player's party fight through a turn-based system.
