Sinopsis
In the near future, society has sunk into corruption, stripped of all hopes and dreams. In this world, the no-rules underground fight scene known as "Yaoyorozu" has reached the height of its popularity. Brutal street fights break out anywhere and everywhere, driven by money and desire. Jin Matsuriya, a delinquent boy who has been surviving by stealing on the streets, gets caught up in this violence. But his potential as a fighter is overwhelming... A hard-hitting battle action series begins, as an abnormal monster smashes everything in his path.
