Nanatsuiro Drops

based on the eroge by unisonshift. we've got our main character, tsuwabaki, a normal student, but one day he bumps into a weird guy with “not cosplay ears” who gives him a drink. it transforms tsuwabaki into a chibi lamb! the teacher explains everything, and the teacher tells him the only way he can get back to normal is to find a chosen girl and have her catch the 7 stardrops. the only thing is, is he can't tell his true identity.
