|“||Seriously, how nice that both the president and Yuzu are so busy! Not even participating in the field trip! However, being able to focus on something without even paying attention to your surroundings, I'm just a little jealous.||”|
Himeko is a teenage girl of short stature, with her most noticeable feature being her thick and bushy eyebrows. Her plum hair (black in the anime) is tied up in two short twin ringlets. Her eyes are magenta (dark purple in the anime). In school, she wears a neat uniform, yet outside of the academy she dresses in extravagant dresses and over-the-top outfits. She is rarely seen wearing anything casual.
She has a rather stuck-up and stubborn personality, and despises people who don't follow the school regulations, the most common objects of her disapproval being Yuzu Aihara and Harumi Taniguchi. Despite taste for sticking to the rules, she seems to enjoy lolita fashion, as she is usually seen wearing that kind of fashion when not in school.
She gets extremely jealous and over protective of Mei, and absolutely abhors Yuzu's close relationship with Mei. It is popularly believed that Momokino harbors intense romantic feelings for Mei, and often emphasizes her relationship Mei by continuously referring to the fact that they were both childhood friends. Despite her seemingly possessive-like personality, she does have Mei's best interests at heart as she begrudgingly accepts Yuzu's attraction towards Mei, however, that does not stop her from frequently complaining about Yuzu's constant breaking of school rules. She's also scaredy, quickly clinging to Mei after hearing Suzuran's screech (although claiming to be protecting Mei).
- In Japanese media (such as anime and manga), characters of high social standing, such as Himeko herself, are commonly depicted with ringlets.
- Despite being the first to find out about Yuzu's crush on Mei, Himeko appears to be unaware of it in the Drama CD. Additionally, she continues flirting with Mei, but she seems to be aware that Yuzu and Mei are dating, as she was unsurprised when Matsuri said so.
- Although it could be due to drawing inconsistencies or evolution in Saburo Uta's art style, Himeko's eyebrows appear to be becoming thicker.
