柳瀬 詠歌

Chouji's younger sister who often teases and verbally abuses him, along with their cousin Ryou. In school, she is known as a gentle, academically-achieving, athletic wonder. But in reality, there's more to her than meets the eye.

She's madly in love with her older brother even to the point of always masturbating while thinking of him no matter the place whether is it at home, school, public toilet, etc. Her abnormally high sexual desire for Chouji is permanently affecting her life so at one point she'll try to get rid of her 'Nii-san addiction'. Needless to say, a lewd brocon like her can't really accomplish such a feat so her attempt at doing that will instead lead to a disaster of epic proportions.
