Takane no Jitensha

Takasumi Takane, an 11-year-old boy, lies to his mother about achieving 92nd place in exams, when he actually ranks 112th, and destroys his answer sheets. On his way home, he accidentally breaks the family's old bicycle, which was meant to be given to his younger sister, Tamaki. Tamaki becomes upset with him, accusing him of dishonesty, and Takane starts to resent her. Later, while searching for his lost dog, he meets a man named Yoyogi, who possesses the altered answer sheet marked as 92nd. Yoyogi offers a trade but demands something Takane no longer needs. Takane suggests his sister, but Tamaki appears, looking for him and the dog. Yoyogi transforms her into a glowing object and consumes her. Takane realizes his mistake and resolves to save her. Yoyogi agrees to return Tamaki if Takane can beat him in a race using the broken bicycle.
