Shiena Amamiya

Shiena is a first-year student at Sachigahara Academy and a good friend of Ryumi. Outside of school, she works as a part-time model and is known for her eye-catching fashion sense—a natural influence from her parents, both of whom are renowned fashion designers. Bright and sociable by nature, she finds herself on the verge of failing her classes, which leads her to proactively seek tutoring from the protagonist, Jun. Her assertive personality and slightly mischievous behavior often cause misunderstandings around her, making her a lively and essential supporting presence in the story.
