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 buys magic caster elf slaves and treats them as little more than expendables. Though elf 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 skill. His body is then dismembered by the elf slaves.

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

Trivia

 * In the web novel, Erya is killed by Brain Unglaus, as Brain became a vampire under Shalltear Bloodfallen.
