A version based heavily on the anime with completely different scripts from the original.

Nanatsuiro Drops is a dating simulation/adventure game based on the anime of the same title. It tells the story of Masaharu Tsuwabuki who is transformed into Yuki-chan, a toy lamb every night because of a can of soft drink. To break the spell, he needs a special girl to collect all the stars bits that fell into the city during the night of meteor rain. To his surprise, this girl happens to be Akihime Sumomo, a classmate whom he hardly knew. There is one more catch, if he lets her know that he is Yuki-chan, he will be stuck as Yuki-chan for the rest of his life.For players who preferred pairing Masaharu up with heroines aside from Sumomo, here is your chance, since several other classmates make their appearance in this game, exploit every possibility and view all the different storylines.
