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. One is that unlike her family; her chest is not very developed, only an A-cup which has finished growing. Compared to her mother and sister's F-cups which continue to get bigger throughout the series. 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 him in such a way that it deliberately presses her crotch against his face as well where she moves his hands to her breasts and holds his wrist in place so he can't pull away. In one instance, Yuriko and Chiharu's breasts are temporarily switched by one of Kyoko Morooka's experiments gone wrong. It's notable that during this time that Chiharu has smaller breasts Densuke doesn't think about her at all, while he is suddenly obsessed with the flirtatious, and now quite busty Yuriko. While Yuriko is in possession of her sister's breasts, she keeps Densuke captive in her room and forces him to play with her breasts for hours until the procedure in reversed. It's heavily implied that Densuke would much rather be with Yuriko instead, but stays with Chiharu because of her larger breasts.
