Desper

Desper (デスパー) is the younger brother of the King of the Underworld, Desher, and Ouken.

Appearance
Desper is an average-height man with blond hair, brown eyes, long eyelashes, and a thin moustache. He wears a red coat with a white fur collar, white hose, and enormous black bloomers with gold details.

Personality
Desper appears to be a typical dandy, obsessed with his own appearance and favoring the finer things in life. In spite of his outward appearance Desper seems to be a capable and resourceful man, and has gladly taken on Bojji as his apprentice (for a price).

Desper believes his older brother, Desher, is deeply envious of both Desper's abilities and Desper's good looks. This is a dubious claim, as Desher's abilities seem to rival or exceed Desper's, and Desher appears to be comfortable with his own appearance. In all likelihood Desper may be the one who is envious of Desher. The two have an antagonistic relationship.

In spite of their fraught relationship Desper is loyal to his brother, and won't hesitate to cooperate with him to protect the Underworld.

Though Desper appears to be a very frivolous person, he cares deeply for Bojji and shows enormous empathy for the young prince, even going so far as to stage a "fake" fight to help Bojji gain confidence in his abilities.

Demigod
Desper is a demigod, or a human/god hybrid. In contrast to his brother King Desher, Desper inherited a very small amount of his father's power. This power manifests as the ability to sense the strengths and weaknesses of anything he touches, including living beings. He prefers to use this ability to sense the hidden strengths in people, and then help them develop and master those strengths.

In Bojji's case Desper was able to sense that the young prince has absolutely no physical strength. He was also able to sense that Bojji had excellent speed, accuracy, and intelligence, which Desper then trained Bojji to use in a new personal fighting style.

Desper's ability to sense strength & weakness is so great that he's able to discern weak bonds between molecules.

Communication Magic
Desper is capable of communicating with his older brother, King Desher, over vast distances. He does so by speaking into his own cupped hand. The two are able to hear each other and converse freely.
