Despa is a prince of the Underworld and the middle child—younger brother to King Desha and older brother to Ouken.
At first glance, Despa comes across as a total dandy obsessed with his looks and luxury. But he's actually sharp and resourceful underneath all that, which is why he took on Bojji as an apprentice (though naturally he charged a fee). Fans often note the contrast between his superficial persona and his genuine capability.
Despa insists that Desha is jealous of both his abilities and his appearance, which is. probably not accurate. Desha's actually way more powerful and seems perfectly content with how he looks. Odds are Despa's the envious one, even if he won't admit it. The two brothers have a genuinely tense dynamic.
That said, Despa's loyalty to Desha is real. When it comes down to protecting the Underworld, he's all in, regardless of their personal friction.
The thing that makes Despa interesting is how much he genuinely cares about Bojji beneath the vanity. He showed real empathy for the young prince—even went so far as to stage a fake fight just to help Bojji build confidence in himself.
As a demigod (half-god, half-human), Despa inherited only a fraction of his father's divine power, which puts him in stark contrast to his brother. His ability lets him sense the strengths and weaknesses of anything he touches, living or otherwise. He's best known for using this gift to find the hidden potential in people and help them develop it.
