Mona, in her own words, has got the looks, the personality and is the "complete package". She is like the queen bee of the school and is idolised by the entire student body - except for Medaka who is totally indifferent towards her. This annoys her and she decides to make Medaka fall for her through her charms.

Mona Kawai is a teenage girl with a bright and energetic appearance. She has long, straight blonde hair that falls just past her shoulders, with soft bangs framing her expressive, purple-pink eyes. She often sports a friendly and cheerful expression.

Her outfit is a typical school uniform: a pastel pink sweater with a school crest on the left chest, worn over a white collared shirt with a yellow accent. She pairs this with a green and yellow plaid skirt that reaches mid-thigh. She completes her look with brown loafers and teal socks, adding to her lively, approachable style.
