AOYAMA Ryuhei must deal with the fact that two of his students at a special high school for the learning impaired; Takashi and Yuya have just disappeared. He set out to look for them with his fellow teacher, KOBAYASHI Daisuke. After searching for both students almost everywhere they could imagine they would go, the teachers are amazed to see them flying over in the balloon. Takashi and Yuya are scolded after that but Ryuhei does not feel so strict to his students. He believes that teaching is not just teaching students but giving them back what they give the teachers.
