A member of the original Maken-ki (at Tenbi). These days, she serves as the academy's school nurse and the object of the male students' fantasies, because her unbelievably large breasts. In the manga, she's shown to be acutely aware of how they think of her and is self-conscious because of it. Whereas in the anime, she fails to realize why she gets so many visits to her office.
In the AWA fics, Aki is allies with the All Worlds Alliance.
In the XP4 fics, Aki debuted in XP4 Heroes Coalition - Mission Chronicles.
In the TWA fics, Aki debuted in the Twisted World Animania - Maken-Ki!.
Aki is a rather tall young woman with bright blue hair (more purplish in the 2nd season and OVA) and light brown eyes. She has a slender, curvy figure and giant K-cup breasts. With her buxom bust and voluptuous body among all woman in Tenbi Academy, Aki is obviously become a fantasy subject to all the male figures in the academy.
Her primary and common attire consists of her wearing a large white lab coat which she keeps open, since she is a school nurse of the academy. Under the lab coat, she wears a pink strapless top which is openly laced down the middle that reveals a lot of her cleavage, along with a very short brown skirt. The aforementioned short skirt does have a tendency to ride up on her whenever she stretches or bends over, in which case she is typically seen wearing green panties.
Matching her slightly naive immodesty, Aki typically wears very revealing clothing, with her typical skirt being extremely short, usually riding up whenever she would stretch or bend over revealing her panties, and one of her swimsuits was a simple sling bikini which was thin enough to reveal her nipples.
In a flashback in the 5th episode of Season 2, it is shown that Aki had already developed large breasts at the time she was 12 in elementary school.
Aki is one of the benevolent, gentle figures and she is very kind with all the students and all the school staff. She is shown to be a very naively immodest person (i.e. a clothing kultz) when situations arise. A running gag of this personality quirk of hers is the fact that she is constantly shown revealing some part of her body - most commonly her panties - unintentionally.
Aki has never had a relationship and is still a virgin even with her veteran figure, and is in no hurry to change that fact, as seen in season 2 episode 5 OVA where she makes Takeru her boyfriend in order to prevent her mother from finding one. She does want a relationship but would like to sort the matter for herself. When Minori Rokujoureveals her virginity to Takeru Oyama and Kengo Usui, she is mortified, and begs the boys to keep it to themselves. Takeru said she would be a good bride and that he want marry her. After that, she blushed and was really happy to hear that.
