Yu Han Sung


 * "Sometimes, because they conceal themselves, they appear smaller than they actually are"


 * - Yu Han Sung to Lo Po Bia Ren

Yu Han Sung (유한성, Yoo Hahnseong; or "Yu Han-Sung") is a High Ranker and the Test Director of the Second Floor. Notably, he is a key member of FUG in taking Viole to the top. He is the main antagonist of Part I. As a member of FUG, he also seems to dislike the Zahard Family. However, like many other members, he may have his own personal beliefs.

Appearance
Personality== Yu Han Sung is a man with long blonde hair. He is said to be over 500 years old. He is drawn quite feminine or rather, androgynous. He always wears robes, usually blue and yellow.

Personality


Yu han Sung has been seen as an extremely intelligent and perceptive person. He is addicted to instant food, which is the cause of many jokes directed at him. Behind this simple outer shell however, is the fierce and deadly "Submerged Fish" who destroys those who may pose a threat to the Tower. It has been discovered that the "Submerged Fish" attitude was merely a façade, he tried to make it look as if he was trying to hurt the Regulars, so they could climb the Tower more easily.

Also, like many geniuses in real life, he probably recognized and admired Koon Aguero Agnis' talents but relished the thought of crushing him  as he likely couldn't tolerate the existence of another "genius", due to his own pride and ego.

Despite of his abilities that could easily grant him a better job on higher floors of the Tower, Yu Han Sung remains as the 2F Floor Admin to fulfill FUG's goals. He claims that one must "weed out those who will bring harm to The Tower". However, he is recognised for his strength which Lo Po Bia Ren stated "impressed even the Vice Commander". SIU stated than if Yu Han Sung didn't mess around in Evankhell's Floor, his rank would have been similar to Yuri's.

Yu Han Sung has been described as a chairman by SIU. As in: he makes people "fight each other for his advantage".

Tower of God: Part 1
Yu Han Sung is one of the Rankers proctoring the tests on the Second Floor. He directly proctors the Door Test, in which the Regulars have to rely on a few scant clues to select the "correct" door out of twelve identical doors. The real answer to the test was in fact to open any door before five minutes were up.

Later, Yu Han Sung discussed the results of the Crown Game with Lero-Ro. He stated, that the Floor of Test was to filter the dangerous, not the skilled, and then pointed out that Baam failed to triumph in the Crown Game due to Yu Han Sung sending Hwa Ryun in.

Later, Yu Han Sung observes the Hide-and-Seek Test with Lero-Ro. He is in charge of grading the overall team. He talks to Lero-Ro about Koon performance, cryptically noting that Regulars would have to drop off "excess weight", signifying their comrades, as they climbed higher and higher up the Tower. He also reveals his cruel side, as he states that he wanted to destroy Koon due to his multi-faceted personality.

When he announces the results of the Position Test, Mauchi becomes angry; Yu snaps his bones with Shinsoo. Koon then comes down and says that he wishes to get a test from the Guardian, to which Yu replies that he is insane and that to get such a test one would need to be an Irregular. When Baam reveals that he is an Irregular, Yu allows him to see the Guardian. Afterwards, he tells Baam that he has been trying to destroy him all along.

Before the Final Test, he tracks down Ren and engaged him briefly, before stating that their goals were the same and that there was no reason for them to fight. He reveals his power to Ren as the "Submerged Fish" of the Second Floor.

During the Final Test, he reveals to Evan that everything had been planned by the Guardian and that the seemingly unusual events were part of the test. He also seems to have some connection with Rachel and Headon.

Tower of God: Part 2 - The Return of the Prince
He is contacted by the 20th Floor director, Augusgus, who refers to him as "The Submerged Fish".

Later in a flashback set three days after Baam's presumed 'death', it is revealed that the rings given to the Regulars were custom-made with tracking devices. As he hands over Baam's friend list as he states "Starting from today we will start your training to become a Slayer. For each and everytime you show a shred of weakness we'll kill one of your friends. You will know how many survived, once you've climbed The Tower... Jyu Viole Grace-nim" before walking away to reveal a woeful Ha Jinsung.

Powers & Abilities
Yu Han Sung is a powerful High Ranker of FUG and apparently a genius Wave Controller. An example of his strength is his ability to easily summon and control an enormous fish close to the size of a White Steel Eel. It can be considered that he was an incredibly powerful genius when he climbed the Tower. Ren stated that Yu Han Sung possessed power that even shocked RED's Vice Commander. He is at the standard of a High Ranker's strength. It is funny to note that when Yu Han Sung said he didn't want to fight Ren, it wasn't him being afraid of Ren's power, but rather the political consequences of battling against a RED member.

Shinsoo: He is a master of Shinsoo manipulation, mostly known for his position of Wave Controller. He was also able to sense that Koon had extra Regulars hidden in his bag, after he passed the Door Test.

Anima: His favourite animal to control as an Anima, is a gigantic fish he nicknamed "Submerged Fish" after his Sobriquet.

Wonsulsa: It is unknown if he is a legitimate Wonsul user, or whether he learnt Wonsul naturally.

Dansulsa: He is apparently a Dansul user.

Notes & Trivia

 * Rak referred to Yu Hang Sung first as "Golden Turtle" and later as "Coffee Addict Turtle".
 * According to SIU, he is deeply connected to Hendo Lok Bloodmadder.
