The most beautiful girl in school and a recognized beauty in society, she stands at a very tall 172cm and works as a professional model. She seems to have inherited her figure from her mother and her overwhelming height from her father. As a celebrity, she uses the stage name Akina Anna. Her weight is estimated to be in the early to mid-50kg range. To the public, she is a cool beauty who exudes an unapproachable aura with her mature appearance and professional modeling career, but in reality, she is a natural airhead who is hard to leave alone. Contrary to her mature looks, she sometimes shows an overly innocent side, as if her thinking stopped at kindergarten. While she doesn't lack common sense, she occasionally shows a strange sense of things. Also, as is common with this type of character, she isn't good at flattery and often makes the atmosphere awkward. She has a bizarre habit of teasing her friends or those she considers close. She might hint at wanting a friend to throw away a snack wrapper for her. Seeing her friends clean up after her when she stuffs candy wrappers in her pockets only to spill them messily, or her just dumping the task on them, seems to be her way of showing closeness. Notably, this behavior of dumping tasks completely disappears once her feelings for Ichikawa surpass mere liking. However, while the frequency has decreased significantly, there are still scenes where she whines like a child for him to do something. She is so unreserved with her friends that she is told to mind her distance, to the point of being a nuisance, but she is actually quite shy. In particular, she has almost no interaction with seniors or juniors and has no male friends at all. Toward people who aren't family or friends, she acts so formal it's almost like she's putting on an act. Her public 'cool' image is actually her default state in front of people she isn't close to; her attitude changes 180 degrees from how she treats friends, becoming very cautious. However, because she is fundamentally gentle and kind, she is very good at becoming close to people she meets for the first time despite her shyness, and once she does, she often sheds that formal layer. Due to the combination of her shyness and gentle personality, she finds it very difficult to say no. When someone makes a burdensome request, like hitting on her, she usually escapes the crisis by ignoring them or feigning ignorance, but she is weak against someone who aggressively pushes to the point where it's hard to shake them off, making them her natural enemy. There have been many such cases where she would have been led away if not for a friend's help. While she seems like a typical airhead, she has a very sharp eye despite her childlike personality. She secretly observes her surroundings very well while pretending not to. She is extremely afraid of being a nuisance to others or, further, being hated. For example, during a group presentation, when she realized her paper was such a mess that a friend had to remake it from scratch, she kept a dark expression and eventually burst into tears, leaving her friends confused as they didn't know the reason. Her extraordinary observation skills stem from this negativity. Because she knows she causes a lot of trouble for others, her habit of being overly conscious of others' opinions to minimize that trouble developed into sharp observation. Furthermore, this observation skill works in a negative way; if a bad situation occurs, she first blames herself and feels immense guilt. To make matters worse, if it's revealed that she really was the cause, directly or indirectly, she becomes half-dazed or hits rock bottom, murmuring nothing but "I'm sorry." She is a huge glutton, often seen snacking on chips or treats in the library, of all places, making her friends dizzy. Even though bringing snacks to school is prohibited, she stubbornly pulls them out from somewhere and eats them, showing incredible greed for food. Not just snacks, her basic meal portions are easily two to three times that of others, and it's a mystery how she maintains her figure despite eating that much. She says she jogs and does indoor exercises consistently, but she reacts very sensitively when her weight is about to be revealed, suggesting she maintains it by a very thin margin. Moreover, she stuffs the trash from her eating into her pockets or spills it, causing a nuisance to those around her. Dumping snack wrappers on close friends to throw away is already a daily occurrence. Her friends usually just accept it or even play along. She likes mint chocolate ice cream.
