Grace Mirchea Luslec (그레이스 미르치아 루슬렉, Geuraeiseu Mireuchia Luseulaek) is Slayer No. 1 and the living "god" of the most dangerous and secretive criminal group, FUG, in the Tower.[1]

Although FUG’s true motives and goals are not clearly known, it is true without a doubt that they exist in the shadows of the Tower, hiding and corrupting. People call Luslec the "God of the Devils" (악마들의 신, Ahkmahdeuleui Shin) or "Demon King" (마왕, Mahwahng; 魔王).[1]

Even though the FUG has a dangerous status, the influence of Luslec's group can never surpass the Family Heads of the 10 Great Families, as long as they hold contracts with the Tower's Guardians.[1] Nevertheless, Luslec holds a rank that surpasses a few of the Family Heads. This is because he represents the "Absolute Darkness" of the Tower.[1]


Luslec was one of those that helped the 10 Great Warriors climb the Tower.[1] Garam Zahard stated that he was a warlord serving under the irregular 'V' who was part of Zahard's original 12 companions.[2] No one knows how or why he fell and became the leader of a such a dangerous group; although the author hints that it has something to do with how Zahard became king and the forgotten civil war his master fought against Zahard and the 10 Great Warriors.[3]

In Part II, it is revealed that Twenty-Fifth Baam had joined FUG and adopted his family name, becoming Jyu Viole Grace.
