Yu Han Sung

Yu Han Sung (유한성, Yoo Hahnseong; or "Yu Han-Sung") is an Advanced Ranker and the former Test Director of the Second Floor. He is a well-known Ranker partly because he declined to be a High Ranker. He is also well-known as "The Genius Wave Controller" as stated by Lo Po Bia Ren, a member of Zahard's Royal Enforcement Division Assassin Unit. He is a key member of FUG in capturing the Irregular Twenty-Fifth Baam and forced him to become a Slayer Candidate. He was the main antagonist of Part I. He plays an important role as a character because he is well versed with several details surrounding the main story of Tower of God.

Notes and Trivia

 * Despite his feminine appearnce, he is actually a "male". Author SIU confirmed this in his Q&A with fans at NAVER fancafe in 2010.
 * Yu Hang Sung is an important character in the entire story of "Tower of God". Even though he did not appear much at the beginning of Season 2, he is close to important main stuff.  His role can be seen in the fact that his Data Form was able to convince Khun Eduan's data on the Hidden Floor of Baam's existence and was able to persuade Evankhell to go along with some of his plans.
 * According to author SIU himself, Yu Han Sung is deeply connected to Hendo Lok Bloodmadder.
 * SIU stated in his Q&A 2010, that Yu Han Sung is very close to being a High Ranker, which means that would make him be in Advanced-Ranker category. This was later emphasized in his encounter with Lo Po Bia Ren. According to Ren, Yu Han Sung rejected High Ranker's position by coming to Evankhell's Floor.
 * SIU also stated if Yu Han Sung didn't mess around on Evankhell's Floor, his rank would have been similar to Ha Yuri Zahard, who is a top 500 High Ranker. This statement might explain Yu Han Sung's action of rejecting High Ranker position; he was avoiding to be promoted to High Ranker by playing and messing around.
 * He is capable of doing all Positions.
 * Rak referred to Yu Han Sung first as "Golden Turtle" and later as "Coffee Addict Turtle".
 * He is the endorser of the Maxim coffee brand as seen in a vending machine.
 * It is yet unknown how Han Sung obtained knowledge on V whilst still a D-rank Regular.
 * According to SIU, he just loves every instant foods.
 * As suggested by SIU, Yu Han Sung's name has a meaning. Yu-Han in Korean means finite. Sung is a suffix that means having characteristics of. This hints that Yu Han Sung life is finite, which would make sense given his connection to Hendo Lok Bloodmadder.
