"Jonan City" is a rural town in the Kanto region. There were five young men who grew up in this small town. Katagiri Ren, Miyagi Taisei, Fujita Hideto, Takasaki Shinya, and Obayashi Yusuke. They were the 26th generation members of the Jonan Ikka biker gang, which has a long history in this town. They were known to the public as "delinquent".

But above all else, these 18-year-old boys were bound together by a strong bond. Their way of life shone with the greatest brilliance, brandishing the "now" as their everything, their excess energy, and the crosses in their hearts that they could not bear.
