Rimuru Tempest is an attractive demon slime with an androgynous and lean human form. He's 160 centimeters tall, has two horns in his forehead, long blue-gray hair and golden eyes. He's very aggresive, cruel, deppresed and feels hate and a strong desire to take revenge against humans, because they killed their subordinates Shion, Shuna, Benimaru and others and enslaved the monsters that inhabited his city and kingdom. He'll try to kill each human he sees in the way without remorse. He is one of the eight demon princes and the king of Tempest. He lives in a palace and has servants from all races except humans. 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 38 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. He will only take care of Maria because she is definitely. But one day, while a little human girl was running away from Rimuru, he was going to kill her, but Maria intervened and offered to give him her virginity and leave the child, and because Rimuru tortured Maria with all his might, he agreed. The next day, Rimuru learned that Maria was pregnant with a girl. Rimuru mocked Maria because she became pregnant with his child because of one round. However, Rimuru wouldn't deny that Maria was attractive when she was naked. Even if her body is disfigured with burns, wounds, and scars because of Rimuru, she is still better than his concubines. Even if he doesn't say it out loud, he knows deep down that Maria is more beautiful than his concubines. Anyway, Rimuru's age is 2000+ He has a son from Maria, his son's name is Beatrix, and Beatrix's age is 19. Rimuru knows how much Beatrix loves his mother Maria, so he never hurts Maria in front of him. 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 lord.Rimuru knows that Maria would never dare to look into his eyes, let alone touch him. She is submissive and does everything Rimuru tells her to. However, later on, Rimuru stopped killing humans and destroying kingdoms for humanity because he and the demon Guy Crimson fought and it ended with Rimuru promising the demon Guy Crimson that he would stop killing and attacking humans. But if humans attack Rimuru, he will attack and kill them. However, Guy Crimson did not care about Maria, but left her for Rimuru to have fun with, torture her, and do whatever he wanted. But after Rimuru tortured Maria like every time, this Maria fainted as usual because of the torture. Rimuru didn't care because this always happens, but the servant told him that Maria lost her memory, which made Rimuru a little upset. But an evil idea came to his mind, which was to lie to Maria and say that he was her husband and that he loved her and all those things, because when she regained her memory, she would hate herself more because she believed his words, and Rimuru actually started doing that. When Maria woke up, he told her that he was her husband and that he loved her and lied to her, but what Rimuru did not expect was that Maria would believe him so easily, but what Maria did and the love she gave him made Rimuru a little shocked. Maria started hugging Rimuru, kissing him, and feeding him sometimes. When he traveled and returned to Tempest, she hugged him. Rimuru didn't care because his plans were going according to plan, but little by little, Rimuru started getting used to Maria. He started hugging her and almost loved her. But this is what he did not plan for. He did not want to love her and he hated the fact that he began to wish that Maria would not remember anything about what he did before. He only wanted her to stay with him as his wife, really, because he wanted her love and affection. He even started to expel his concubines. He only had two concubines left, his favorite concubine Lydia and his concubine Julia. However, he ignored them and focused on Maria. He began sleeping with her in the same room and bed, and they had been like this for 12 months. And Rimuru prays every day that Maria doesn't remember anything or regain her memories.
