Madoraco

Madoraco (마도라코) is a High Ranker with the sobriquet "Grey Catfish" known for being a master businessman. He was working with Io and Punk raising money from the tournament for their Workshop research but betrayed them in the end. A silhouette that looks like him was shown among part of the FUG faction that oppose Jyu Viole Grace gaining the Thorn, it is confirmed that he is truly a member of FUG in the tournament conclusion arc.

Appearance and Personality
He's a short man, has pale pink hair that is combed back and a pair of black horns protrude from his head. His skin is pale, his eyes are yellow and he has a huge mark in his mouth that makes him seem to have a smile at all times. Also he dresses in a black suit, which together with the wand he carries, gives him the appearance of a magician.

He is a calculating man and is particularly interested in money. According to the Moderator's Factory, he is allied with dangerous people.

Appears before the Workshop Moderators telling them they could earn a lot of money to complete their research by using a betting system in the Workshop Battle and not to worry about if the director finds out, as he would take care of everything. Then he tells his subordinates that soon Jyu Viole Grace would be in his hands.

His silhouette is later seen amongst the Slayers and Elders in FUG who oppose the young Slayer candidate being granted Enryu's Thorn to be used as a weapon.

Closure
Meanwhile Madoraco watches on and muses about how Viole's friends were attempting to escape during the Workshop Battle. He thinks of making a move even if there will be some collateral damage. Suddenly one of its subordinates enters his room to tell Madoraco that a messenger from the Tournament area had arrived; he questions who the messenger is. He then receives the messenger and later converses with his attendant, saying that the information they received from Reflejo via Cassano was more useful than holding the deal with the Workshop Researchers and ordered them to prepare the solution as they were going to hit them before they escaped. He finishes by saying it was time to end the tournament.

Shortly afterwards Viole defeats Reflejo with Enryu's Thorn, Madoraco sends one of his Rankers to the Archimedes' tail to drop the dissolving solution to create their ultimate weapon. Seeing the solution being dropped, Punk and Io confront Madoraco with the latter revealing that he had given their promised reward to someone else, since he had received a better offer. The two Workshop moderators are riled and draw their weapons but Madoraco knocks them down.

At Madoraco's location, a figure appears and greets Madoraco, unnerving him. After conversing about Gustang's involvement in the current affairs, he tells all his FUG associates to withdraw and meet back at their headquarters. Madoraco
