Yé serves as a supporting character within Shanghai's Qing-Bang triad organization and maintains a friendship with protagonist Kenshiro Kasumi. During the "Game of Death" storyline, Yé was slated to compete in a martial arts challenge. Kenshiro Kasumi intervened, disguising himself as Yé to replace him in the fight against an opponent named Goran. While operating under Yé's identity, Kenshiro employed the "Gate-Shattering Finger Strikes" technique during this combat. This substitution underscores a protective dynamic between Kenshiro and Yé, implying Yé might have been unable or unwilling to face the challenge directly.
