He has magical powers. Rimuru hates Maria and despises her and loves to torture her but he doesn't kill her because of her ability to see the future and he needs her but instead of killing her he tortures her by hitting her or killing someone in front of her because she is afraid of blood and bloody things and he loves to see her afraid and enjoys it and loves to see her afraid of blood and loves to see that scared pleading look with the big innocent wide eyes like the eyes of a puppy on her face because it is fun in his opinion and he also doesn't understand why everyone fell in love with Maria even his subordinates who want revenge on humans fell in love with Maria to the point that even the demon princes fell in love with her too he doesn't understand why even though she is human she made everyone fall in love with her. Ever since Rimuru brought Maria to Tempest, that is, throughout her stay in Tempest for nine years, he has been torturing her and breaking her bones for trivial reasons. Once he broke her foot, once he broke her wrist, once he broke her hips, and he did all of this for trivial reasons to the point that he killed the person she considered her father in front of her eyes, cut off his head, and put it in her room for a whole month just because she stood up to him. He loves to break her bones and loves to see her cry and suffer. Rimuru's age is 2000+ He has a son from Maria, his son's name is Beatrix, and Beatrix's age is 19.

He doesn't like that Beatrix loves Maria more than him, but he overlooks the matter because Beatrix is his only son. Rimuru became happy after Beatrix turned into a demon day, Beatrix suddenly screamed and called his father. The servants were also terrified because Maria had turned into a five-year-old little girl . Rimuru was shocked and no one knew why.
