Synopsis
Eleven-year-old Takasumi Takane is promised a new bicycle if his exam results place in the top 100, but he ends up at 112th. He lies to his mother, claiming he got 92nd, and shreds the answer sheets. While returning from cram school, he accidentally breaks the old bicycle meant to be handed down to his younger sister, Tamaki, angering her. She then accuses him of lying, and he starts viewing her as a nuisance. One night, searching for his missing dog, Chris, at a shrine, Takane meets a young man named Yoyogi. Yoyogi inexplicably possesses the answer sheet marked "92nd." He proposes a trade but threatens to return the sheet to its rightful owner unless Takane gives him something he doesn't need. Takane offers his sister, Tamaki. At that moment, Tamaki arrives looking for Takane and Chris. Yoyogi transforms Tamaki into a shining object and swallows her. Realizing his mistake, Takane wants to save her. Yoyogi agrees to restore Tamaki if Takane beats him in a race using his broken bicycle. Can Takane win the race and rescue Tamaki?
