This individual is the guild master of Ainz Ooal Gown and is highly respected among the NPCs of Nazarick's Great Tomb. Known for being cautious and meticulous, Momonga always plans and controls every detail to avoid any haphazard actions. His opponents are never underestimated, so he tends to overkill them as a result. Since his transfer to the new world and becoming an Undead being, Momonga has become more cold and calculating, suppressing his emotions. He is loyal to his friends and creations and acts with nobility towards those who follow him. Momonga only does things that benefit Nazarick or himself, whether it's gaining information or prestige. Although he has a sense of justice and doesn't hate humans as much as his followers do, he feels nothing about their deaths.
In the New World, he is the Sorcerer King of the Sorcerer Kingdom and the most powerful magic caster in the world. His other identity is famously known as "Momon," a dark warrior and leader of Darkness, an adamantite ranked adventurer group of that nation. He is an adamantite class adventurer and the strongest adventurer known in E-Rantel. His real name is Satoru Suzuki.
