Code 18

The narrative kicks off on September 11th, 2018, this year. Hayato Hino is currently a senior at Ryuusei Academy in Tokyo, where she attends Ryuusei Academy and is a member of the school’s Second Science Club. On that particular day, he goes to the school’s roof to practice using his “Dragon Unit,” a flight pack. Suddenly, just as he is about to put it to the test, he sees a girl rappelling down from the sky while wearing something very similar. He tries to save her but is ultimately unsuccessful and dies. However, a few moments later, he realizes that he has gone back in time just a few seconds earlier, even though he has no memory of doing so, and that the same thing happened during that time.
