Demiqas

Demiqas is a Human Monk-Outlaw and the guild master of Brigandia, a guild located in and formerly in control of Susukino. After targeting a young Druid named Serara, a member of the Crescent Moon Alliance who had gone on a quest alone prior to the Catastrophe, Shiroe's Party ventures to Susukino to retrieve Serara and put an end to Brigandia's reign of terror.

Appearance
Demiqas is a Monk and uses claw-like Brass Knuckles as his weapons of choice. He has a large build with dark skin and long purple hair and wears armor made of leather and lined with fur.

Personality
He is brutal person and he is willing to kill anyone outside of his guild -- or even those within -- to get the what he wants without hesitation, which is why he is so obsessed with Serara, who managed to escape from his grasp. He seems to only play the game to conquer and has little tolerance for people that will not follow his orders. He is notorious for looting and pillaging unsuspecting travelers of their items and PKing them, even prior to the Catastrophe. His second-in-command is a Sorcerer named Londark, although the two don't seem to get along too well and the guild is split between them.

After his defeat at Nyanta's hands and another one at William Massachusetts', Demikas appeared to have turned over a new leaf as he took a Lander as his wife despite her henpecking him often; unlike how he would PK any of his subordinates, who irritate him the slightest, he now shows to be more tolerant where his wife freely nags him. However, despite being reformed, he still holds a grudge against Nyanta and Shiroe; oddly enough, he seems to hold nothing against Naotsugu, who was with them as well.

Rescuing Serara arc
Demiqas first appears when Brigandia raids and burns down a caravan trying to leave Susukino. When a member of the guild begins to act reluctant, he teleports behind him, knocks him aside and orders the others to strip him of his gear and kill him. Upon hearing that Serara and Nyanta are nowhere to be found, he sends a large group of his men to hunt them down and bring them to him.

Later, Demiqas is seen parading down the streets of Susukino, showing off his pillaged items. He along with the rest of his guild confront Shiroe and his group outside the city's walls in order to capture Serara and Nyanta. Enraged by Shiroe and Nyanta's taunting, he accepts the latter's one on one challenge and engages him in a fight. In frustration, he orders his men to attack only for them to be blockaded by Naotsugu. He is then stopped by Shiroe's Thorn Bind Hostage and reduced to one point of health by Nyanta. After losing Londark and the Healers, he desperately lunges forward in hopes of killing Shiroe. He is cut short, however, when Serara hits him with her staff, killing him and sending him to the Cathedral while he swore revenge on the former Debauchery Tea Party strategist and laughed maniacally. In the light novel, he is killed by Nyanta with his and Shiroe's combo, and Londark is killed afterwards by Shiroe.

Libra Festival arc
Demiqas is seen looking at the full view of Susukino in gloom from his defeat when he is approached by William Massachusetts of Silver Sword. Whether this is before or after his duel with the Assassin is unknown.

Gold of the Kunie arc
After Brigandia lost control of Susukino to Silver Sword, the guild disbanded and most of its members left the city. Demiqas, however, chose to remain in the city and took a Lander as his wife, who now henpecks him constantly. He still harbors a deep grudge towards Nyanta from his defeat, owning a punching bag in the shape of a cat that is able to constantly dodge attacks. Despite his grudge, he is forced to aid Silver Sword's and Shiroe's joint raid party to defeat the Raid Boss for the Abyssal Shaft quest after he barged into Silver Sword's guild hall in search of a fight.

During the battles in Abyssal Shaft, Demiqas refuses to work with the others, claiming that they were too slow, and annoys the other members of the party. He realizes, much to his frustration, that Shiroe was assisting him by buffing him and slowing down the enemies. Unable to do anything while William had his eyes on him, Demiqas instead resorts to taking his anger out on the monsters and the surrounding environment, much to the amusement of the Silver Sword members watching him.

When the raid party fights Ruseato of Seven Prison, Demiqas rushes into battle like usual, and listens to Shiroe's explanation about the Shadow Vanguard. After Junzou tells them to pull the Shadow Vanguard without defeating them, he yells back that he already knew. While fighting, Demiqas looks back at Shiroe and admits to himself that he wasn't as good as the Enchanter, so he would take the time during this raid to train, get stronger equipment, and refine himself in order to defeat him. However, as he is thinking this, Sasameyuki's scream catches his attention after Tarutauruga enters the fray, and is then further shocked when Ibura Habura, too, joined in. After several attacks from the three raid bosses, only he, Shiroe, and Naotsugu are left alive. Seeing Tarutauruga about to attack Shiroe, he leaps forward and kicks Shiroe out of the way, satisfied with seeing the dumbfounded look on his nemesis' way before he was crushed by Tarutauruga's attack.
