Mayuri Shiina

As a second-year student at Kasensou Private Preparatory Academy, this cheerful optimist is known for her dreamy, slow-paced way of speaking. Though she struggles with complex ideas, she prioritizes enjoyment and hates conflict. A lifelong friend of Rintarou, she carries a nostalgic habit of reaching toward the stars, a gesture nicknamed the "Stardust Shakehand." While her sunny disposition is infectious, her tendency to interrupt conversations with sudden movements often catches those around her by surprise.
