joker

Joker is characterized by his reserved personality, but he preferred to observe others silently rather than speaking much or initiating. However, Wooin notes that despite his quiet demeanor, Joker has a short temper, and he is known for his honesty and bluntness, which stands in stark contrast to Wooin's personality. Joker dislikes unfair fights or races, often holding back and quitting, which may explain his infrequent participation in racing events. He exhibits an unpredictable nature, easily getting distracted during races, such as when he stopped to save an injured puppy which he soon took care of it and he adheres to the law to the extent that he stopped at traffic lights during races, even though he is an underground club fighter and associates with Wooin as his friend. Despite rarely giving his best while racing, Joker is perceived as both aggressive and vulgar man who can be quite violent around people he's fighting with, yet there is an underlying politeness and gentleness to him.

He's the undefeated champion in the underground cage fights scene. He seems to be doing it for the money to take care of his family. He has two younger siblings, but it is yet to be revealed if his parents were still around since it appears he was most likely the one taking care of them financially, as shown he also cooked for his brothers with the money he earned from illegal fight club and other shady works with Wooin and his crew.

He's mostly shown working closely with Wooin and are often seen together when the latter is mainly up to something like schemes and seeking for entertainment. Besides, Joker also had no problems taking orders from Wooin, which may or may not imply that Wooin had sort of an authority over Joker.

Joker is very tall, he usually towers over every one around. He has light blue (almost white) hair. He has a tattoo of a dagger on his right cheek, right below his eye, and a scar running from the left corner of his mouth to his jawline. He wears two dangling earrings on his right ear. During competitions, he wears a matching black windbreaker with the word Sabbath running down left front panel. The words and logo, adorning the back of the jacket, is burnt orange in color. During races, he wears a white helmet with the Sabbath crew logo on one side and a joker sticker on the other.
