A new book for high school students. If you don't like it, don't criticize it. This is a dragon who traveled to the ordinary world and saw his future self in the past. He has learned magic for 16 years, but he has learned it for nothing. Now he comes here to learn mathematics that he doesn't know at all. Isn't this nonsense? At this time, it depends on how he can turn things around. Only if he continues to live, will he find that the world is still a little different.
