Gangryong's martial arts master, who taught him EOTL. As a master of EOTL, one of the Heavenly Five Paths and a traditional martial art, Yoochun opposed Reunion goals, and became their greatest enemy, leaving a lasting impression that still affects Gangryong's life at the school. A fan of anime, he liked to imitate some of his favorite attacks. Yoochun did not believe that a practitioner of EOTL would benefit from artificial ki, as EOTL relied more on refinement of ki than on quantity. Latter it is revealed that Yoochun also uses Northern Broad Strike to give him a better chance agaisnt Yuri. He is assumed to be killed by Yuri.
Techniques:
* Lightning Fist - Uses metal element to create lightning, has a stun effect, the effectiveness depends on the user's skill which can produce either a current that stuns the opponent for a long duration of time or a current that lasts only for very short time. This also depends on who the opponent is because if they are powerful enough, dispersing the effect with their own Ki would be quite easy. * Thunder Break - Uses enemies Ki to create lightning, it disrupts an enemies Ki flow, the effectiveness of the technique depends on many separate factors, the user's skill level in the art and current condition when using Thunder Break, and the opponent's toughness and body density, with these factors the effect of the disruption can be very damaging or very weak. * Heaven's Void Lightning Brand - Long distance attack that uses lightning in a similar form to Arts of Heaven's Riches Spacial Void Fist to scar Vera[2] * Northern BroadStrike - A "formless" fighting style, and an external martial art, said to rival Heaven's Riches internal martial arts; Lightining Tiger uses to be able to fight Yuri on a more equal ground.
