Background / History

Ulbert was a member of the group that became Ainz Ooal Gown. He openly teased Mu Fengyu while also expressing confidence in his abilities, and he favored bold retaliation when Storm Horn pursued Peroroncino. He supported Mu Fengyu's plan to infiltrate Storm Horn's base with a World-Class Item, opposing Touch Me's more cautious approach 2 10.

During the group's reorganization into a guild, Ulbert initially resisted Touch Me's proposal but accepted its practical advantages. He declined the guildmaster position and instead nominated Momonga, citing Momonga's frequent activity, fairness, and meticulous nature 40.

As a damage dealer in Momonga's squad during the Great Tomb of Nazarick raid, Ulbert received major spell amplification from Momonga before using Great Calamity against the final BOSS 45 52 54. His attacks remained central to Ainz Ooal Gown's competitive-event tactics, where he could erase enemy parties or secure monsters with overwhelming area damage 63 65 68.

After arriving in the New World, Ulbert reappeared alongside Bukubukuchagama, apparently having previously died. When the group debated whom to revive with Cecilia's Flower, he argued that logistics-oriented companions were more valuable than additional combatants in prolonged conflicts 118 120.

Later, under the human identity “Mr. Odel,” Ulbert investigated a decadent auction house. Repulsed by its exploitation of enslaved women and the desires of its clientele, he formed a soul contract with Alya, healed her, and chose to destroy the establishment 125 129. He subsequently sent Alya to the Slane Theocracy with tools to incite a demonic catastrophe, assigning Demiurge to ensure her survival 130 131.

Appearance

Ulbert is a demon who normally presents himself as a human magic caster. His undisguised body was embarrassing enough that he immediately hid behind a flower to dress after reappearing 118 125.

• Uses the human identity Mr. Odel and claims to be a fifth-tier magic caster while operating among nobles 125.
• Wears a mask when entering the auction house, following its anonymity rule despite dismissing the practice as trivial 125.
• Can perceive the strongest desires within human hearts 125.

Personality

Ulbert is blunt, disdainful, and impatient with excessive caution. He was eager to retaliate against Storm Horn and dismissed Touch Me's concerns over risking a World-Class Item, though he eventually accepted the need for structured guild organization 10 40.

His combat confidence is matched by a pragmatic strategic outlook. Despite possessing exceptional destructive power, he advocated restoring logistics personnel before frontline fighters, arguing that Nazarick needed sustainable resources more than additional damage output 120.

Ulbert holds human greed and exploitation in deep contempt. He found the auction house and its patrons disgusting, yet treated Alya with a limited degree of consideration: he healed her, allowed her to seek her friends, and stated that he would not force her to act against her wishes 125 129. This does not extend to general mercy; he watched a royal capital fall to demons with little visible concern and encouraged Alya's revenge 130.
