Yuzu Aihara (藍原 柚子,Aihara Yuzu?), née Okogi (小此木,Okogi?), is the main protagonist in the manga Citrus. She has a younger stepsister, Mei Aihara, who moved into her house after her mother married Mei's father Shō Aihara.
Yuzu is a teenage girl with dyed chestnut blonde hair. She has emerald green eyes, and has two piercings on each ear. She is very fashionable, and keeps up with the latest trends. Her natural hair color is brown, and during the 17th and 18th chapters of the manga she temporarily wore a jet black wig.
Yuzu is a self-proclaimed gyaru. She is a daring, outspoken, and an often shameless girl who enjoys dressing up, wearing make up and customizing her school uniform, which clashes with her school's rules, often leading into problems with the Student Council. She emphasizes on what relationships have to be like to cover up her own inexperience of them. She attempts to be as girly as possible, and detests the academy's no make-up policy. From the beginning of the manga she is portrayed as a "dumb blonde", yet slowly as the manga progresses her more domestic and caring attributes are manifested. She is a creative cook, and often will cook for herself and Mei when their mother is busy working.
Despite her attitude, with hard work, she is shown to be able to get good grades in tests. Despite Yuzu acting like a child at times, she does her best to make the people she cares about happy. She is considerate, yet clumsy and brash. She is incredibly bubbly, and her optimistic side often manifests itself in her conquests for Mei. She cares not for school rules or upper class views, and she's more interested in what society on a whole thinks of her.
After finding real love she became considerably happy about it wanting to show her affection more. However, she found out the hard way that not everyone will approve of her relationship with Mei, leading her into a state of depression and resulting in failing her exams. It wasn't until she got encouragement from Mei that she snapped out of it.
