Jin Soon is a member of the vigilante gang, the Knights. His history is unknown before a decade ago, though blood tests prove he's nearing his tercentennial. In 4119 he enrolled at Juneau's Anatali University, majoring in ancient literature and AI programming. After meeting Trent and the other Knights, Jin has tagged along painting calligraphy and developing his line of synthetic monkeys, Project Bobo. Passive in opinion, he takes a backseat to Trent and Sacha, who are two hundred and sixty years younger.
His wisdom and intelligence aren't his only assets—Jin's combat skills are unequalled among the Knights and Justice. He is a practiced, graceful swordsman.
Fun Fact — Rumored to have mastered of a rare Shinjitsu ribbon technique, said to dazzle foes into incontinence. Reliability of the claim is questionable.
