Mirei is a bright, energetic, glamorous, and cute girl who is usually smiling while having a confident & cheerful vibe to her. She is fair-skinned, has light blue eyes, and long, bright, straight waist-length bubblegum pink hair with light blue undertones and some volume. She has an elaborate long decorative side braid on her right side, tied with yellow ribbon-like segments, and thick, straight-cut bangs covering the forehead.
She wears her school uniform in a cute, clean, and fashionable way, with a cyan jacket-like top with a dark navy shirt underneath, a bright yellow ribbon bow at the neck, matching the accents in her hair and earrings, and a white pleated mini-skirt. She usually wears long black socks that reach slightly below her knees, and black school loafers with a slightly glossy finish. She also wears large, gold heart-shaped earrings. She also has long & yellow painted nails, matching her overall bright theme.
Lastly, she usually wears a large tote-style school bag slung over her right shoulder and held by her right hand which looks practical & stylish at the same time. It also has a design of a vertical stripe pattern with solid dark straps. Her hobbies are nail art & cosmetics, as stated by her during her introduction to the class in chapter 1.
