Personality
Acts mature beyond her years
Absolute weakness for sweets and curry
Terrified of UFOs and the paranormal
Fiercely proud and never backs down
At just nine years old, Mashiro Mitsumine arrives at the Yonomori residence under the guise of keeping tabs on her brother Hakuya's fiancée, Benio. Armed with her clan's mystical abilities, she skips several grade levels to enroll in high school, constantly striving to project the dignified air of a proper future sister-in-law. Yet beneath that haughty exterior hides a child who completely falls apart at the mere mention of UFOs or aliens. Her two greatest weaknesses are sugary treats and curry, and she finds Benio's relentless, smothering affection utterly exhausting to endure.
