Shed that Skin, Ryugasaki-san!

Story

Ryugasaki-san is a lizardgirl. Her tongue is like that of a chameleon's, her hands are like that of a gecko's, and she even has a third eyelid! Due to her unique biological makeup, she sheds her skin multiple times a year. This wouldn't ordinarily be an issue, but she suddenly finds herself (or rather, her skin) the target of a classmate's affections. The peculiar Yugami-kun has a particular interest in reptiles, and Ryugasaki-san's unique physiological features have caught his inquisitive, meticulous eye. Thus begins the story of a budding romance between two very unusual individuals.
