Ha Jinsung

Ha Jinsung (하진성, Ha Jin-Sung) is a High Ranker of the Ha Family, and a member of FUG.

Background
Ha Jinsung was originally from the Ha family, but at some point he defected to FUG, where he trained Viole and Karaka. He was amazed at Viole's talent to mimic anything he saw once and continually brags about Viole's talents to others. Little is known about Ha Jinsung's backround. From a brief flashback in chapter 116, it seems he fell in love with an unnamed woman who was sold as a slave to the leader of a branch family. In his anger, he annihilated the entire branch, but the woman died as well. This event may have caused him to hold a grudge against the Great Families, leading him to join FUG.

Appearance & Personality
Ha Jinsung is a tall, slender man with brown hair and brown eyes. He is approximately half a head taller than Viole. Jinsung has a perm which most people find cheap and funny. Jinsung has a carefree and fun-loving attitude, although this also serves as a mask to hide his true intentions. Since meeting Baam, his character has mellowed slightly to the point where he feels regret at the FUG's treatment of Baam.

According to Hwa Ryun, he respects Viole's decision to stay with Team Tangsooyook.

FUG Arc
Ha Jinsung first appears as Yihwa finds out that Viole is meeting Hwa Ryun at Regular Karaoke. At first, he wonders if Yihwa is another new member of FUG. Yeon soon realizes that the three of them are FUG members, and he soon notices her Yeon Family hairpin and accuses her of being a spy from the 10 Great Families. Viole tries to defend Yihwa by saying she is his teammate, but Yihwa denies this, prompting Jinsung to prepare to attack her. Viole ends up knocking her out to protect her.

Hwa Ryun then suggests that they take Yeon back to Viole's lodging to chat. There, Jinsung introduces himself to Wangnan and Goseng and asks if they bully Viole, although he eventually ends up going on and on about Viole being a genius. All throughout the conversation, Wangnan responds to his antics nervously.

After Jinsung leaves to see Viole on the roof, Hwa Ryun informs Wangnan that Jinsung had actually come to eliminate all seven of Viole's current teammates to get him to form a better team, but had changed his mind for now, as he respects Viole's decision. She warns him that many FUG members currently have complaints against Viole's current team.

Later, he goes to the roof to see Viole.

Epilogue，Path
Jinsung is troubled when Viole gets hurt from protecting one of his teammates during the test. He tells Team Tangsooyuk that he wants them to leave and that he would guarantee safety from FUG. Wangnan is visibly troubled by this but later returns to tell him that they would be walking their own paths and taking Viole with them, regardless of FUG. After Wangnan leaves, Karaka appears to question Jinsung's motives. He replies that letting Viole have friends simply increases their hostages.

Abilities & Powers
As a member of the Ha Family, Jinsung is proficient at martial arts and also incredibly strong. Not only is he a member of a Great Family, but he is a High Ranker, which heightens the standards one would expect of him. Additionally, even the Elders and Slayers of FUG are wary of angering him, speaking volumes about his strength. In fact he is such a monster that Hwa Ryun stated that even a Slayer would have trouble against him in a serious fight.

Floral Butterfly Piercing Technique (화접공파술, or "Hwajeopgongpahsool"): As the one who taught Viole this trademark FUG technique, Ha Jinsung is a master at using this technique. The technique allows one to transfer a shock of Shinsoo through vibrations from oneself to a targeted object, vibrating the target's inner Shinsoo and destroying it from within. Jinsung was able to completely obliterate a rock golem with what seems like an offhand touch. He states that the technique takes decades to learn, though Viole easily defies this.

Notes and Trivia

 * He is higher up in the Ha family tree than Ha Yuri Zahard.
 * Jinsung tells Wangnan to buy him cigarettes. Wangnan returns with lollipops instead.
 * As the lollipops were Chupa Chups (as commented on by Jinsung), this was a reference to their 1980's ad campain, featuring slogans like "Smoke Chupa Chups" and "Stop smoking, start sucking." This is in line with SIU's other reference to older candies, which were the prize in the 28F test.
 * Jinsung buys clothes for Viole every season, much to Viole's chagrin.
 * Ha Jinsung joined FUG to get his revenge on the Great Families. Though he is very strong he is not a Slayer.
 * He is strong enough to kill an entire branch of Ha family because his love was sold to a branch family head. Though it lead to her death and she became his reason of joining FUG.

Quotes

 * (About Viole, to Wangnan) "He copies anything he sees once!"
 * (to Yu Han Sung) "Rage dulls the senses. I feel like those dull senses have come alive today."
 * (to Karaka) "Doesn't the fact that Viole is making more friends, mean we have more hostages to use?"
