Sumire is a 17 year old high school girl who wants nothing more than to make friends with her new classmates. She's so dissappointed that they all seem to hate her, calling her a pervert, a dirty old man, creepy, weirdo... alas, what is a poor lifesized puppet to do in this cruel world.

Soon however, she gets accepted by her class and starts to change the futures of her classmates with 'her' unbridled enthusiasm.
