Revenge: Blood for Blood (2011)

Tamaki (Hitoshi Ozawa) and Kudo (Kazuya Kimura) were once senior and junior classmates during their student days. Even after becoming a yakuza and a detective respectively, they continued to respect one another. However, the police undergo a complete restructuring, shattering the fragile balance that had existed between the organizations. Launching what they call the “Minami Purification Operation,” the police move to eradicate the criminal underworld. The ailing boss of the Yamashina-gumi dies following brutal interrogations, forcing the organization into dissolution. After completing his prison sentence, Tamaki gathers the scattered former members once more and swears vengeance against the police—to settle the score for the murder of his boss.
