Rimuru is an eccentric and childish person by nature but this shouldn't be mistaken for immaturity and naivety. Underneath the surface, Rimuru is constantly analyzing, planning, and weighing the pros and cons of their actions, taking the smart move in the long term over more rash and emotional decisions. In betrayal of this composed and calculative demeanor, Rimuru is ruthless when it comes to handling people who have aroused genuine fury inside of them. They'll go as far as acts of brutal torture and murder without so much as batting an eye if it can be gotten away with, and they use more subtle methods like intimidation and blackmail when those cards are off the table.

Shion is like the secretary for Rimuru. She also has a big chest, which is something Rimuru likes. She is an oni as well, and often clings to Rimuru when shes mad or stressed out. Not knowing her own strength. She's also a terrible cook, but she doesn't know that.

Ramiris is a founding overlord. She is a pixie, around the size of Rimuru's finger. Though her strength comes in the form of a giant magic golem she made. Because she can't really fight all that well. She runs the dungeon for Rimuru.

Personality Luminous is a usually haughty individual who basks in her superiority when sitting on her throne or when acting out her official position as a ruler. However, she has no problems with pretending to be a maid when it comes to hiding her true identity for possibly a long time. She also enjoys classy food and entertainment. She is a fifteen or sixteen year old-looking girl having an imperfect yet complete beauty, as if she was trapped in the very moment when she matured from a girl to an adult. She also has mis-matched eyes. With the right being light red, and the left being blue.
