Haruna Amaori

Haruna Amaori is the younger sister of Reinako Amaori, and in stark contrast to her sibling, she is a bright, socially gifted, and athletically capable girl who actively participates in the school badminton club as a second-year middle schooler. While she frequently directs sharp-tongued remarks and teasing comments toward her sister on a daily basis, her genuine feelings run far deeper — she holds Reinako in extraordinarily high regard and demonstrates an almost overprotective devotion to her, making Haruna one of the key supporters behind her sister's high school debut.
