Takane soll zu seinem Geburtstag ein neues Fahrrad geschenkt bekommen, allerdings nur, wenn er bei dem anstehenden Test in der Schule die Top 100 erreicht. Doch zur gleichen Zeit spielen sich mysteriöse Vorfälle in der kleinen Stadt ab. Was haben diese zu bedeuten und wird Takane sein neues Fahrrad bekommen?

　　高澄高岭（坂本真绫 配音）的母亲答应她，如果他能够在接下来的模拟考里获得年级前100名的名次，就给她买一辆自行车。遗憾的是，成绩公布后高岭只考了112名，但是由于实在是太想要自行车了，高岭偷偷的扔掉了试卷，向妈妈撒了谎。虽然得到了梦寐以求的自行车，但高岭却没有想象中的那么开心，更糟糕的是，刚拿到自行车没多久，高岭就把车给弄坏了，这让原本等着接收哥哥的二手自行车的妹妹十分愤怒，她向妈妈揭穿了哥哥的谎言。 　　晚上，高岭推着破破烂烂的单车来到神社，发现了一个神秘的小店，店主告诉高岭，自己有100名以内的考试试卷，要高岭拿妹妹来交换，高岭同意了。

An 11-year-old boy, Takasumi Takane, will be given a new bicycle if his exam results are in the top 100, but his results put him in 112th place. He tells his mother a lie that he placed 92nd, and he tears the answer sheets apart. On his way home from cram school, he accidently breaks the old bicycle that he is supposed to hand down to his little sister, Tamaki. This angers Tamaki. Furthermore, Tamaki accuses him of telling a lie, and he begins to think of her as a nuisance. One night, when he goes to a shrine to look for his missing dog, Chris, he encounters a young man named Yoyogi. Somehow, Yoyogi has the answer sheet marked as “92nd." Yoyogi proposes a trade, but threatens to return the answer sheet to its original owner unless he is given something Takane doesn't need.
