FUG




 * "Why are you so shocked? Did you really think that we were nice people?"

F.U.G (퍼그/FUG, Peogeu) is the most dangerous and secretive criminal group in the Tower lead by Grace Mirchea Luslec. Their official members explicitly (though not all the time) wear the "Mark of the Slayer".

FUG is often compared to the Walhaiksong because of their opposition to the 10 Families. However, whereas the Wing Tree which is more of a "social club" centered around several members, FUG is a "religious organization" centered around a single faith:  to kill Zahard and the heads of the 10 Great Families. Although the relationship between the two organizations are not that good, there are a few members who are associated with both groups.

Although FUG’s true motives are not clearly known, it is true without a doubt that they exist in the shadows of the Tower, hoping to accomplish their objectives.

The 10 Families forbid anyone within their Families to enter FUG and they consider it an important duty to eliminate their members, who are known to hide within the shadows of the Middle Area. Despite its dangerous status, it does not mean that they hold enough influence to challenge Zahard and the 10 Families. As long as the 10 Family Heads hold the contracts with the Tower’s Guardians, FUG’s influence cannot overcome the Family Heads. In particular, Zahard holds such a contract that prevents the inhabitants of the Tower to kill him. In order to bypass such matter, the organization awaited a long time for someone free from the Guardian’s Contracts: an Irregular (such as Jyu Viole Grace) or a power source (such as Enryu's Thorn) not bound by the contract and incorporate them to their ranks.



Slayers
Within their infrastructure, FUG has 11 Slayers (슬레이어, Seulaeiyeo). The origin of the name is very simple: "One who kills" Zahard and the 10 Families.

There are presently 7 Slayers active: 5 have unknown whereabouts, 2 are acclaimed as "devils" and the remaining 4 positions are vacant. All are supposedly very powerful.

"In FUG, there are those who have a grudge against 10 Families and Zahard, those who envy what they possess and those who want to change the Tower. A Slayer is a GOD who fulfills their wishes."

Slayers are treated as walking Gods by FUG members.

Organization Information
FUG is an organization dipped in shadows. They are a group, so they can be called an organization. They have no visible physical forms or headquarters, but at least one headquarter is known: Bayroad. As it is a place hidden in the Tower, we can assume that the other places of gathering or control of the group are as secretive (the Wine Glass on the 2nd Floor might have been one as well).

Structure
The structure of FUG is slowly appearing as the story goes. At the top are the Slayers who are considered living gods. The number one Slayer is Grace Mirchea Luslec, also called "God of the Devils". Then there are the Elders, who take decisions with the active Slayers on the great plans of the group, for example appointing specific personnel for delicate missions. Then there are High Rankers who hold specific positions and power within the group (ex: Ha Jinsung who is the martial arts teacher of the Slayer candidates). Slayers command over executives (probably at least at the level of a Ranker. Ex: Karaka commands over Poken). Executives have dormant Regular agents planted on different Floors that wait, sometimes for a thousands of years, until they are called to accomplish their missions (ex: Reflejo). Finally the executives can recruit Regulars that are fervent believers in FUG (ex: Xia Xia).

Though there seems to be a structure and a head to the organization, that doesn't prevent dissensions among the group. As for now, a splinter centered around a few Slayers and Elders has decided and put forth a plan in order to alienate the powers of Jyu Viole Grace and the Thorn.
