Dormas

Dormas (ドーマス) is one of the Four Heavenly Kings of the Bosse Kingdom, known as "Swordmaster". He was Bojji's original swordsmanship instructor.

Appearance
Dormas is a tall man with shoulder-length, red-blond hair and brown eyes. He wears a long, light blue tunic cinched with an even lighter blue belt, khaki pants, and knee-high black boots.

Dormas has lost his dominant hand from the wrist-down, and has replaced it with an articulated metal hand of unknown origin. This hand is similar to a plate mail gauntlet, and is affixed to Dormas' wrist by unknown means.

Personality
Dormas is dedicated and well-intentioned, but also arrogant, easily-lead, stubborn, and a bit thick-headed. He deeply idolizes King Bosse, to the point where he based his personal sword-style on Bosse's overwhelming, physically-dominant fighting style.

The qualities that allowed Dormas to become a master swordsman and one of the Four Heavenly Kings are, paradoxically, the same qualities that make him a very poor teacher. His stubbornness and inflexibility meant that he couldn't adapt his teachings to Bojji, and indeed Bojji seems to have learned very little from him in spite of his years of dedicated teaching. However, that same dedication allowed Dormas to quickly master sign language, and become one of the few members of court who could communicate with Bojji as well.

Similar to Hilling, as he grew accustomed to Bojji's disabilities Dormas also became colder and more distant, unable to cope with his feelings of personal failure over Bojji's lack of growth.

Dormas previously put loyalty to the king above all else, even his own moral compass. This ultimately lead to him being manipulated into attempting to assassinate Bojji, an act he immediately and deeply regretted.

He appears to be the youngest and newest of the Bosse Kingdom's Heavenly Kings, because of this he is ignorant of the kingdom's early history, and does not know of Lady Miranjo.

Plot
Dormas is the Swordmaster of the Four Heavenly Kings and Bojji's original swordsmanship instructor. After the death of Bosse, Dormas quickly found himself caught up in the various plots consuming the Bosse Kingdom, and was ordered to kill Bojji by the newly-crowned King Daida. Ultimately Dormas attempted to follow this order, though he immediately regretted it.

Forced to face what he had done by Hokuro (a guardsman accompanying him on his journey), Dormas first pretended to have no regrets, only to later sacrifice his own dominant hand in penance while fighting with Hokuro.

Still at-odds with the young guardsman, Dormas allowed Hokuro to return to the Bosse Kingdom to report what had happened, only to secretly follow and save Hokuro from his own execution. During the chaos of their escape, the two encountered King Bosse reincarnated into the body of Daida. Bosse gave the two men a secret mission: Destroy Miranjo's Underworld portal, located deep below the Bosse Kingdom's castle.

While attempting to complete their mission, Dormas and Hokuro encountered King Desher and a detachment of the Order of the Underworld, who had used the portal to invade the Bosse Kingdom's castle. Dormas resolves to hold them off himself.

Master Swordsman
Dormas is a genius swordsman who has mastered the blade and created his own sword style. This style was modeled after the physically-dominant, unrelenting fighting style of King Bosse himself. Bosse was so impressed by Dormas' swordsmanship that he made Dormas a Heavenly King, and appointed him Bojji's personal sword instructor.

Even after losing his dominant hand, Dormas remains a masterful swordsman. He has acquired an articulated metal hand to replace the one he lost, and seems to have adapted to it easily.
