Denji Akiyama, also known by his ring name "The Assassin," is a professional boxer who shook the world upon his descent into the Sweet Science. A hefty heavyweight, he had natural punching power, amplified by his trainer and Father Figure, Harrison Fischer, along with quick hand speed comparable to most middleweights. Kick-starting his career as an amateur fighter, he kept the judges in his favor behind the jab, often winning by clean decision. He didn't win every bout, of course, but he was pretty damn good at what he did. Denji's transition to the pros was successful, winning his first fight by decision, the only decision win he earned until he fought the only man to knock him out, Conor "Viking Warrior" Sullivan. He made the choice to drag opponents into the late rounds just to exhaust them before knocking them down and out. He must've had the spirit of Rocky Marciano flowing within that tough exterior, because he'd almost never grow tired even in the later stages of his fights. He is commonly found keeping in shape at the Big Bear Boxing Gym in California, his home state. Oddly though, any chance he had at the title, he and Fischer refused to take it.
