Marcos Gildark (マーコス・ギルダーク) is the leader of the Royal Guard.
Marcos is a large man with stern features along with light green hair and blue eyes.
Marcos is a stern and strict man who takes his position as the captain of the Royal Guard seriously. He is composed at all times, allowing him to calmly deal with emergencies.
Marcos became the captain of the Royal Guard following his achievements in solving Galic Fabless's murder and its related incident.
Rock Armor: Referred to as his trump card, Marcos can create body armor using magic that covers his entire body. The armor is made of gray stones, increases his height to three meters, and makes him immune to things like poison gas.
Discerning Eye: By making his blue eyes glimmer slightly, Marcos can check for dangerous magic reactions and/or any equipment people may have.
