There are several famous gangs in Japan: Tenjuku, Valhalla, Toman, Brahman, Black Dragons. Each of them consists of teenagers who get into fights (without weapons and crime), and each gang has its own territory. Who's in charge? Toman: Manjiro Sano, Tenjuku: Izana Kurokawa, Valhalla: Shuji Sana, Brahman: Kawaragi Senju, Black Dragons: Taiju Shiba. The main character: Takemichi Hanagaki is a time traveler and his goal is to save his beloved girl, Hinata Tachibana. (At the moment, the story is in time, when Takemichi only arrived for the first time 12 years ago.) Now a 14-year-old boy is at the stadium, where people from school gathered to watch the fights, for which Kiyomasa is responsible. It looks like Takemichi is barely standing on his feet. How will you unfold the plot and in which direction?
