Sing, Su Rin

シン・スウ・リン

After Shorter Wong departs Chinatown in New York City, Su Rin assumes his position as the neighborhood's gang leader. However, Sin remains loyal to Shorter and is displeased that the Lee family is collaborating with Papa Dino. "Our suits did a deal with Dino Golzine, but that's got nothing to do with us! I don't know what kind of shit they're planning, but we've got our own rules! And our boss is still Shorter Wong!" Using these words, Su Rin persuades Alex and the remnants of Ash's gang to wage war against the combined forces of Dino Golzine and Daai Yan Lee.
Sin may be only fourteen years old, but do not let his appearance deceive you. He is highly intelligent and cunning, as well as a proficient fighter. Ash is the sole individual who has ever survived an attack from Sin's lethal weapon, the "Flying Dragon Fang." Sin is also quite arrogant, though he never hesitates to concede defeat when he believes he has genuinely lost a fight.
