園部 ひかり

Sora's younger sister. A third year student at Seiryu Academy and Makio and Seiji's childhood friend. She is a gentle and kindhearted girl who hopes to enter nursing school after graduation. She is in the same class as Makio, and has recently become extremely concerned by his sudden change in attitude toward herself and Seiji.
In reality, she and Makio had begun dating just before his mind was tampered with. She has no knowledge of Seiji's true nature, nor of his role in causing Makio's strange behavior./
