Karaka

Karaka (카라카, Kahrahka) is a Slayer in FUG. His secret hideout is located on the 97th Floor.

History
His history is unknown for the most part, however, it is known that he was trained and tutored in martial arts by Ha Jinsung for some time. During the time Karaka was a Regular he received special assignments from FUG while he was taking his tests. Depending on the nature of such tasks, Karaka would assassinate a specific Regular during the test, help a specific Regular to pass the test or fail all the other Regulars and pass the test alone. It is said that the goals those assignments was probably to violate or mock the rules of the test.

Appearance and Personality
Little is known about Karaka's true appearance, as he has only been seen hidden in shadows or in an armoured suit. The only detail known for certain is that he has striking yellow eyes and hair. Karaka also owns a ring with Zahard's symbol on it, like Ja Wangnan.

Karaka appears to be one of the more hard-line FUG members, advocating swift action against Zahard no matter what moral issues stand in the way. Also, he seems to put his own agenda over that of FUG's. He apparently already has the to mess with the Elders of FUG. He is one of the youngest Slayers (슬레이어 중에서는 아직 어린애정도지만: a Slayer, but yet a child among them), "a rising star of evil".

FUG
Ha Jinsung saw him hiding in the shadows, noting that he was on the Floor too.

Epilogue, Path
Jinsung called him out and greeted Karaka before saying they should move elsewhere as the Guardian was watching. Karaka referred to Ha Jinsung as "master" and spoke to him respectfully but then stated his mistrust for him, adding that some Slayers and Elders of FUG were beginning to doubt Jinsung, before ending by saying that Viole's teammates should be cleared out of the way. However, Jinsung retorted that if they kept them, there would be more hostages to use against Viole in the future. He finished by telling Karaka he had a plan, to leave it to him and also to tell those Slayers and Elders the message. Karaka politely agreed he would and left. On his way out, he ordered Poken to gather some trustworthy Regulars to watch Viole's teammates in secret, and if they showed any suspicious behaviour, he was to kill them all.

Tower of God: Part 2 - The Workshop Battle
It is later revealed during the Development Tournament of the Workshop Battle, that Reflejo intended to give Karaka the Thorn after implanting Viole within it. It is likely that Karaka planned this.

Closure
After the end of the Workshop Battle, he received a brief and unexpected visit from his old teacher, Ha Jinsung, who gave him a warning. After Jinsung left, he mused about Viole and the possible problems he may bring. After Poken told him that he had a message from the "Submerged Fish", he told Poken "this time, no mistakes".

A Month
His underling Pedro informed him of the advancement of their plan to obtain the Thorn as well as resurrect a former Slayer.

The 'Name Hunt' Station
Having come to the Hell Train, Karaka connected to Pedro's memories where he discovered what had occurred up to that point, including that Ha Yuri Zahard was on the train.

Powers and Abilities
While he has never been seen in battle, he can be assumed to be very powerful as he is a Slayer of FUG and his teacher was none other than Ha Jinsung, a High Ranker in the top 100 of the rankings. SIU noted that he has much potential and is already quite skilled.

Notes and Trivia

 * SIU mentioned that he is one of the driving forces of the Tower of God story.
 * Karaka is assumed to be male, though due to the particularism of the Korean language, their gender remains unspecified.
 * As a Slayer, Karaka is a highly respected member of FUG with many loyal and relatively powerful subordinates, such as Poken and Pedro. His ranking is currently unknown but Jinsung said he is climbing them quickly.
 * According to SIU, Karaka is a character that will appear often in Part 2. That is, of course, often for a Ranker.
 * Poken calls him "My God". (All Slayers are supposedly treated as Gods by FUG members.)
 * According to SIU, Karaka chooses to wear a mask because he's ticked off at Ha Jinsung.
 * SIU planned for Karaka to appear without a mask but, because there were a lot of new faces at that time of the story, he decided to make him wear a mask in order for him to look more mysterious. He also had to change the drawing of the chapters he appeared in.

Quotes
