Demiqas

Demiqas was the guild master of Brigandia, a guild located in and 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 therefore 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, although he still holds a grudge against Nyanta and Shiroe; oddly enough, he seems to hold nothing against Naotsugu, who was with them as well.

The Depths of Palm
Demiqas first appears briefly in The Depths of Palm where Brigandia raids and burns down a caravan trying to leave Suskino. 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.

Escape
In Escape, 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 breaks sanity and lunges forward in hopes of killing Shiroe. He is cut short however, when Serara hits him with her staff, killing him and presumably sending him to the Cathedral while swearing 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. The first trail ended in failure, after it was revealed that Raid Bosses had gained intelligence and were now capable of leaving their territories to aid each other, when the party faced not one but three Raid Bosses at once. After reviving, they undertook the quest again, with Demiqas attracting the attention of Ruseato's Shadow Soldiers long enough for Shiroe to reach the end goal.
