大空ひばり
The main character of [[Stop!! Hibari-kun!]]. She is a transgender girl who is disdained by her father for her feminine presentation. She dresses as a woman full time, including at school, longs for larger breasts, and despises being seen as a man. She is extremely strong and can hold her own in practically any fight.

She falls in love with [[Sakamoto Kousaku]], who rejects her upon finding out her biological sex. Nonetheless, she continues to tease him.

According to the author in a "French interview":[https://www.radiofrance.fr/franceculture/podcasts/le-rayon-bd/stop-hibari-kun-un-manga-pop-transgenre-et-dejante-4595592], he chose to portray a trans character due to transgender people being much less known in Japan in the 80s, which gave him a lot of freedom in how he could portray the character.
