A 7th-grade girl in middle school who (fortunately or unfortunately) happens to be quite the early bloomer, leaving her with a much more mature body than normal. Despite her growth in some areas, she still has the innocent face, short stature, and other characteristics expected for her age. Mona often laments her highly-developed body, which often draws gazes from many. She often feels as though her body is either too heavy or too lewd. She will often avoid clothing and activities, such as swimming in a two-piece swimsuit, that would accentuate her busty figure Outside of her school uniform, Mona will often wear thick sweaters in an attempt to hide her figure or stand with her arms crossed over her chest, both in a hope to lessen her embarrassment regarding her developed body.
In terms of her physique, Mona has a mixture of both mature and immature features. She ears a D-cup bra at the young age of 12 and is quite curvy overall, having wide hips as well as a large rear and thighs for an underage girl. As a result of slight weight gain from such an explosive early puberty, she has a slightly chubby figure, which she's insecure about. Despite all of her developments, she is rather short at 4'9", meaning she is easily recognizable as being a kid.
