Aihara, Yuzu

藍原柚子

Yuzu, a self-proclaimed Gyaru and only child, transfers to an all-girls school following her mother's remarriage. She is outspoken, daring, and somewhat shameless. She is frequently seen wearing her uniform in a manner that violates school rules. Unfortunately, this draws the attention of the Student Council President, who enforces the dress code. Yuzu eventually returns home to discover that she has become the older sister of the Student Council President, Aihara Mei.
Although she initially shows irritation toward Mei, her concern for her sister evolves into infatuation and deep care. While rebellious at school, she has good intentions and often acts to protect Mei. Additionally, her closest friend at school is Harumin.
