Yuriko Shinonome (東雲百合子)is Chiharu Shinonome's younger sister.
Yuriko wears the Zashono Academy uniform, with a pink sweater instead of a vest and purple skirt with red shoes.
She is almost the exact opposite to her sister for 2 reasons. Unlike most of her family, her breasts are not very developed, only reaching a B-cup. In contrast to her mother and sister's F-cups which continue to get bigger throughout the series. This is something she is very jealous of.
The other difference is that, unlike her sister, she not only openly confesses that she likes Densuke Mifune, but constantly makes amorous advances towards him. Being an athletics star, she is very proud of her soft, toned butt, and will flaunt it in front of Densuke to seduce him. Often jumping on him in such a way that she deliberately presses her crotch against his face, as well as forcing his hands onto her breasts so that he can not pull away.
