Yandere Traits Edit
It's initially assumed that Miyuki is obsessed with Shinichi, the playable character. However, Miyuki reveals that she's actually obsessed with the player, aware of her existence as a visual novel character. She believes that since they played through her route first that it must have meant that they genuinely loved her. However, near the end of Aoi's route, she lashes out at the player by killing Eru the cat and Aoi, and breaking Shinichi's limbs. She calls them out for daring to play through another route when they had her. Before she kills Shinichi, she begs for them to say that they love her, which they can choose to do or to say that they hate her. To ensure that they don't play through Aoi's route again, she calls "God" and reprograms the game, making it impossible for them to restart the game or load another file.
