Erya Uzruth

Erya Uzruth (エルヤー・ウズルス) was a worker and the leader of Tenmu. He and his slaves volunteered to explore and investigate the mysterious large tomb.

Personality
Being confident of his own skill and talent, Erya is very arrogant. He looks down on people weaker than him in public. He also believes that humans are the most superior race, and it is natural that other 'inferior' races should obey humans.

Background
From his human supremacy ideology, people guess that Erya came from the Slane Theocracy. He bought magic caster elven slaves and treated them as little more than expendables. Though elven slaves are quite expensive, Erya have all pay to himself and thus can afford new slaves whenever he wants.

The Invaders of the Large Tomb Arc
After the exploration of Nazarick's affiliated tombs is finished, Tenmu decides to explore the underground portion. Passing through a corridor without any monsters or traps, they eventually encounter training lizardmen and Hamsuke. Hamsuke challenges Erya to a duel to test its own progress as a warrior. Erya is beaten and killed by Hamsuke's martial arts. His body is then dismembered by the elven slaves.

Abilities and Powers
He was a top-class warrior comparable to Gazef, Brain, and Gagaran. It was confirmed that Erya was stronger than Brain in the past tournament of Re-Estize Kingdom.

Elven Slaves
Erya cares very little about the elves, to him they are just tools which he can can discard and easily replace. He cruelly uses them to satisfy his lust and depravity. When they are unable to accomplish a given task, he often uses violence to remedy his disappointment.

Imina
Erya holds the half-elf woman with disdain as much as she does for him. Due to his upbringing in the Slane Theocracy he views her as second class citizen compared to main stock humans. He harbored perverted intentions for her wishing to use her as a replacement for one of his elven slaves, often imagining her at his mercy.
