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

Later, Desha instantly sensed when Miranjo used her magic to free several Underworld prisoners, taking it as an excuse to declare war on the Bosse Kingdom. Desha 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.

Desha personally lead the detachment that used the portal, while Despa lead the detachment tasked with securing Ouken.

Immediately after crossing over Desha encountered Domas and Hokuro, on their mission to destroy the Underworld portal. Though the two managed to slow the advance of Desha'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 Desha's army.

Ultimately Desha willingly retreated to the Underworld with a newly-knighted Gigan, after secretly consulting with his brother Despa. This appears to be part of a larger plan the two have to capture the Demon.

Desha remained in the Underworld during the remainder of the events in the Bosse Kingdom, though he assisted Despa several times by sending his lightning bolts to attack enemies.

Toward the tail-end of the confrontation, Desha was shown meeting with a judge, and accepting his new rank as the #1 king in the world. Not one to waste time, Desha immediately ordered that he be taken to the Divine Treasure Vault.

After entering the vault he decides to use his treasure to save his brother, choosing a Demon girl who heals his brother by giving Ouken his humanity and mortality back, but in exchange Desha loses his memories.
