Ghost Crew

Operating more like a gang of thugs, their leader Hwangyeon Choi, is known for smashing their opponents' bikes when they lose in a race. He and his crew play dirty, often cheating in order to win. In order to stop Vinny from winning, Hwangyeon put a kids toy in Vinny's wheel causing him to suddenly stop and crash. After he won, he and his crew beat Vinny up and used a sludge hammer to destroy Vinny's bike. He was going to using the same tactics with an umbrella on Jay but Jay saw his shadow creeping up behind him and avoid sleazy attack. Hwangyeon's older brother, Sungho, takes care of any injuries the crew gets, likely not out of concern but to save face.

Their competition uniform is all black, making it easy for them to use shadows to their benefit and launching their attacks on the rival teams.

His brother asked the Sabbath crew to teach his crew a lesson for messing with XXX. Wooin and Joker were meant to leave Hwangyeon a long but forgot and broke his nose. For the longest time, they did not know who ordered the attack but upon thinking about it further, Hwangyeon realised his own brother was responsible.
