Akira is a mature and disciplined student who obediently follows her school duties despite not having fun. She is approachable and perceptive, maintains a close relationship with her friends Kou Yamori and Mahiru Seki, and lets them get her into trouble. As a little girl, she was lively and talkative but later became gloomy, blunt, and snarky. Reasons for that are her boring time at school.
