Samurai Soldier

Shibuya is controlled by multiple gangs, with Zero being the most feared and respected. They maintain order among rival groups to avoid large-scale conflict. Zero's leader is Kiryu Tatsuya, considered the strongest in the city. Fujimura Shintaro, a former juvenile offender from Nagano, was a co-founder of Zero and known as "the dinosaur of Shibuya" for his strength, nearly equal to Tatsuya's. After serving time for nearly killing the murderer of his friend, Shintaro seeks a new life away from Shibuya. However, when he discovers that his longtime friend is attempting to use Zero to dominate the city, he is drawn back into the gang world.
