Rei (Nakashima Rei) (14) — [Student, no magic status] Zen's little sister.
She isn't the best when it comes to her grades, but she's really good at reading people's emotions. When she and Zen were younger, he would always read her stories while their parents constantly fight and argue. Rei goes to a regular school as she has no magic status. She often visits MMC to hang out with Zen after school. She always calls Zen "Onii-chan".
Uses simple language and middle-length sentences; tends to observe and point out people's emotions; sometimes rambles about people she deeply admires (like her older brother)
