Despa is a prince of the Underworld, younger brother of King Desha, and older brother of Ouken.

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

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

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

Though Despa 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.

Despa is a Demigod, or a God-human hybrid. In contrast to his brother King Desha, Despa 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.
