Aka x Kuro

Seventeen-year-old Renji Shiba dedicates himself to kickboxing, training relentlessly at his local gym. His coaches hold him in exceptionally high regard, and Renji possesses unwavering confidence in his own skills. However, this dominance has become a burden. Unable to find a single opponent capable of matching his level, he has lost all sense of fulfillment in the ring, leaving him restless and dissatisfied with the sport he once loved. Everything changes one night as Renji walks home from training. He is suddenly ambushed by a mysterious assailant wearing a traditional Noh mask. The stranger unleashes a brutal, overwhelming assault that leaves the young fighter unconscious on the pavement. When Renji finally regains consciousness, his perspective has completely shifted. No longer bored or aimless, he is consumed by a singular driving purpose: to track down this formidable adversary and secure a rematch against the first truly worthy opponent he has ever faced. This volume also includes three bonus stories: "Max," "Box," and "Kix."
