Ai-chan from Getsuyoubi no Tawawa series

https://tawawa.fandom.com/wiki/Ai-chan

A pretty young Japanese woman who stands at just 149 centimeters tall (4 feet and 10 ) and weighs about 50 kilograms (approximately 110 pounds).

She has well-maintained brown silky hair with a nice smell of shampoo which she styles in a bob cut, with the addition of two braided strands behind her ears. During her middle school days as class representative, Ai-chan had much longer hair that she arranged into two ponytails on either side. She also wore glasses back then and currently only wears them at home. Her eyes are described as light-green and big with long eyelashes. Her skin is fair and flawless. She’s usually not wearing any jewelry and barely any makeup as well.

Her overall body is quite slender with a flat stomach and thin legs and just like her mother and sister, she is quite uncommonly curvy, often getting her a lot of attention, unwanted or not. Her breasts are exceptionally large for someone of her size and age and are the main obsession of several characters throughout the series. Her bust growth is a recurring topic of discussion, showing little to no sign of stopping as she went from H-cup at the start of high school to now filling K-cup bras. This unusual feature gave her the nickname “Ai-chan”, a play-on-words with “Ai” meaning love in Japanese but also with the letter “I” in English, her cup size when she first met Onii-san. From her first day, she’s considered as the bustiest girl in her school and her reputation has even spread to other local schools as well.

Ai-chan is most usually seen wearing her school uniform throughout the series, consisting of a white shirt covered with a black jacket while wearing a navy skirt. During winter, she usually wears a beige sweater and a peacoat. Given her impressive bust, she’s unable to close her jacket and her white shirt is most often drawn with large creases showing how much she strains the fabric of her uniform. This eventually leads to her accidentally popping her buttons that she usually saves as gifts to Onii-san every Monday as offerings. Ai-chan has also been shown to struggle to find fitting bras that aren't too overpriced and to wear the prettiest ones on Mondays just for him. She can also be seen at a local bakery wearing a close-fitting white and blue waitress uniform with a blue apron and skirt that emphasizes a lot of her curves. Ai-chan also wore dozens of different outfits, usually underlining her imposing assets, either intentionally or not.

In the light of her striking appearance, Onii-san described Ai-chan’s looks as “youth taking a corporeal form” while her best friend Volleybu-chan couldn’t help but notice how immensely popular she was with boys in their school as dozens of them have confessed to her. Meanwhile, girls have shown to express mixed feelings of jealousy and fascination towards the busty schoolgirl.
