四里 瞳

A first-year student at Sukumi Academy. She is always timid and hides her eyes with her bangs. She uses polite language with everyone, speaks in a way that makes her seem distant, and never expresses her opinions clearly. She generally prefers to be alone in the shade and is not good at being in groups.

She has good results in swimming club practice, but is completely unable to show her true form in competitions. She sunk after a few meters during a training camp.

Ever since being attacked by a chikan in the past, she has become completely shy, and has also developed a fear of men. Her parents somewhat forcefully enrolled her in the co-ed Sukumi Academy, hoping that she would somehow overcome her shyness and fear of men.
