The scum living in the present bark loudly as they chase their dreams! A story of young people rising up while living on the border between life and death.

Tatsuya Ukyo gets caught up in trouble and is threatened by Kuki, the boss of the Kuki group, and is forced to fight at "Dragon Heat (DH)", a gambling fighting arena located in an underground facility in the city.

Former yakuza underling Kazuma Kiryū has recently been released from prison after a lengthy incarceration and is trying to piece his life together and distance himself from his yakuza past. Unfortunately, Kiryū's problems slowly escalate as he is pursued by a former associate, the baseball-bat-wielding psycho Gorō Majima, who has a grudge to settle with Kiryū.

In 1970s-era Japan, three children, Kazuma Kiryu, Akira Nishikiyama, and his younger sister, Yuko Nishikiyama, are raised together in Shintaro Kazama's Sunflower Orphanage. In the summer of 1980, Yumi Sawamura, a young girl whose parents were accidentally shot and killed during a gang's shootout, joins them in the orphanage. Following a yakuza tradition, the honorable Kazama secretly raises orphans whose parents he has directly or indirectly killed. In return, the children love him as a father and he eventually inducts the teenage Kiryu and Nishikiyama into the Dojima Family, a Tojo Clan affiliate of which he is a senior officer.
