Сора Ніімі
As Kakeru’s devoted younger sister and a first-year student, this spirited girl frequently haunts the protagonist's apartment, often demanding free meals or jokingly threatening to move in permanently. While she possesses a playful, somewhat selfish streak-especially when teasing the serious Miyako-her loyalty to her brother remains her driving force. Once her latent abilities awaken, she joins forces with Miyako and Kakeru to actively assist in their ongoing supernatural investigation.
