Okite: Law of Blood(2013)

The protagonist is a former ordinary person who married the daughter of a yakuza boss and became unwillingly entangled with the underworld. The portrayal of the yakuza world, its organizations, and its characters from the perspective of a man not yet fully steeped in violence is fascinating. The Ryusei-kai, led by Yajima Joji, is targeted by yakuza organizations from both the east and west. Known as the “Mobsters” and feared, the secret to their strong unity lies in a blood oath stronger than family bonds. Daisuke, who becomes the adopted son-in-law of Ryusei-kai executive Kitagawa Shunzo, is drawn from an ordinary life into the world of violence.
