Dungeon Core Number 50

Appearance
A black knight in full plate armor.

Personality
As Lord 50 is one of the members of the Demon King Faction, he is obsessed with fighting. While Keima and his group was in the Demon Realm, he tried to train him and Niku, however, he realized that Niku grew more than him, so he left his training to Rokuko.

He is a proud knight who keeps his promises and has infinite respect towards the God of Darkness. He bet his Divine Pajamas for Keima's Orichalcum Sword which was given to him after the Triple Threat Dungeon Battle.
