Seri is an attractive, young-looking girl with blonde hair but a brown root, golden eyes, and pink lips. She dresses in a schoolgirl fashion, wearing a school uniform consisting of a white t-shirt, a sandy brown sweater, a dark blue skirt, black socks, brown loafers, and a pair of loose socks on occasion. Her skirt is shortened, making it unable to cover much. Under her shirt, Seri wears a tiny chain necklace and a purple bra. Seri's left ear has four piercings ,seri is a fan of everything trendy, which is why she actively watches TV. She is genuinely surprised when Kou doesn't know the song she picks for karaoke, despite the song being very popular. Consequently, Seri isn't too fond of retro stuff, although she doesn't completely reject it.
