Grace Mirchea Luslec

Grace Mircea Luslec is Slayer No. 1, the living 'god' of the most secretive and the most dangerous organization in The Tower, FUG. The objective of FUG is unclear, but it is a known fact that they hide in the darkest parts of the Tower and corrupt people. Because of this, people call Luslec 'the god of devils' or 'the demon king'. Luslec is said to have been one of the helpers that climbed the tower with Zahard and the 10 Great Warriors, and it is unknown why that Luslec became corrupted enough to become the leader of FUG. As you can tell from the rank, he is a superb warrior and the giant black hook he wielded is said to have pierced all. In spite of this, Luslec's rank exceeds that of some family heads because he is the one and only symbol of 'absolute darkness' in the tower.
