Kiichi has become a mainstay in these fights, not only because of his outstanding victories but that he refuses to seriously injure any of his opponents, upholding his father’s teachings of never killing anyone.
During one particular match in which Kiichi was on the verge of losing, his uncle appeared only to see the progress of his nephew’s training and to tempt him into using a killing technique on his adversary. Refusing to give into such treachery Kiichi manages to score a win, it was during this fight that we are revealed that Kiichi mistakenly killed an opponent during an MMA (Mixed Martial Art) tournament using a technique that Kiryu taught him.
