Akane is a described as a beautiful young girl with a nice voluptuous and curvy figure, with a beauty that would rival a model. She's of average height that is 165 centimeters, and has short brown hair. She used to have a long hair in her childhood days.
Akane can be classified as a tsundere, being rather short tempered especially with matters regarding Saito, and even go to massive, exaggerated tangents to chastise him even for somewhat minuscule matters. A serious and competitive person by nature, she is generally irritated by constantly losing to Saito in tests and his overall lazy demeanour.
She's not, however, a bad person and is generally friendly with others. Akane is nonetheless easily embarrassed and has shown difficulty to express herself properly at times, mostly with Saito, which results in unintended actions for which she feels badly after calming herself down.
Living together with Saito, forces her to retrospect herself, and be more willing to concede and cooperate, resulting in less hostility and lowering more of her guard.
More than anything she's laser focused on achieving an undisclosed dream, and is willing to marry Saito to achieve it.
She is Saito Houjou's fellow classmate and rival. When she's not speaking, she possesses a beauty that could be compared to that of a model. However, whenever she encounters Saito, they end up in constant disagreements. She harbors a strong competitive spirit, is diligent in her efforts, and values her family. Additionally, she has a dream she is determined to achieve, even if it means marrying Saito.
