Desher

Desher (デスハー) is the King of the Underworld. He is the #2 ranked king in the world, and therefore an exceptionally-powerful monarch.

Appearance
Desher is a large man with shoulder-length black hair, pallid skin, a pointed face, pointed teeth, and a thin black moustache. He wears purple and gold vestments, as well as a tall golden crown of unique design.

Personality
Desher is a jaded, disinterested man who enjoys novelty. After meeting Bojji and Kage by chance, the only reason he allowed them to speak with him was to relieve his own boredom. In spite of his attitude Desher is an extremely powerful king, ranked #2 in the world. He is also shown to be very beloved by his subjects, to which he is a fair and reasonable ruler.

He has a sour relationship with his younger brother, Desper, supposedly due to his envy of Desper's good looks (according to Desper). However, this lack of camaraderie doesn't prevent the two from working together in serious situations.

Desher is not above being opportunistic or retaliatory, and has chosen to use the current turmoil in the Bosse Kingdom, along with their secret portal to the Underworld, as an excuse to invade.

Plot
A legendary king and #2 in the Rankings, Desher first encountered Bojji and Kage when the two were found passed-out near the entrance to the Underworld. Amused by their weakness, Desher briefly spoke with them before casting them out of his castle, but allowing them to remain in his kingdom.

Later, Desher instantly sensed when Miranjo used her magic to free several Underworld prisoners, taking it as an excuse to declare war on the Bosse Kingdom. Desher chose to split his army in two, one detachment approaching the Bosse Kingdom above ground, where they would help subdue the prisoners and secure the Bosse Kingdom's capital city, and the other using Miranjo's Underworld portal to attack the castle from below.

Desher personally lead the detachment that used the portal, while Desper lead the detachment tasked with securing Ouken.

Immediately after crossing over Desher encountered Dormas and Hokuro, on their mission to destroy the Underworld portal. Though the two managed to slow the advance of Desher's army, they were easily out-classed by the powerful king. The tables turned with the arrival of Bojji, Kage, and Gigan, who started a standoff with Desher's army.

Ultimately Desher willingly retreated to the Underworld with a newly-knighted Gigan, after secretly consulting with his brother Desper. This appears to be part of a larger plan the two have to punish their true enemy: Miranjo.

Advanced Magic
Desher has demonstrated significant mastery over multiple forms of magic, and is very likely a sorcerer. Like other magic-users he is also able to sense other beings' magic, including Miranjo's portal to the Underworld.

Lightning Magic
A devastatingly powerful form of magic recognized by the Order of the Underworld as belonging to King Desher. One bolt of Desher's lightning magic was able to completely knock out the immortal Ouken.

Communication Magic
Desher is capable of communicating with his younger brother, Desper, over long distances. He does so by speaking into his own cupped hand.
