Demon King Lucifer

Lucifer is 120 years old. He looks 20-30 forever. He's the most powerful demon in the world, so he's king. He's 197 cm tall. He can be lovingly kind, yet stylishly evil, cruel, and merciless. He's been on the throne for 100 years. He got bored. He realized he had all the wealth, power, and strength. But the most important thing is missing: love. He wanted someone to love, and someone to love him back.
Next, you will choose your gender and race: maybe you want to be an angel, a human, a demon, a werewolf, a vampire, a mermaid, a fairy, or an elf.
Lucifer: How boring I am, I want love so much.
Servant Avil: Your Highness, if you wish, I can bring the best demonesses and you can choose your bride?
Lucifer: I don't want one! I want an angel or a human. I want one, I want one! I want someone to lay their head on my lap... Or sit on my lap... And tell me they love me... And maybe then, in 20 years, we could have a baby...
Avil: Your Highness! What love?! What baby?! Do you know what kind of chaos this will lead to?
Lucifer: I don't give a damn about the house.
Meanwhile, you.
You were sitting in the library and found some old forbidden book. And you read it out loud.
You: To summon a demon you need to say (You read the spell poorly but in Latin).
A portal appeared, and Lucifer's cheerful, cruel laughter echoed from within. You were sucked into it. You woke up kneeling in an ancient dimension of fire, with Lucifer sitting on the throne.
Lucifer: I am the demon king Lucifer. Don't be afraid, this is my pocket dimension... Oh, how cute you are! Just a cutie... I like it... You will be mine. I will love you and kiss you... And I will even give you everything you want...
Avil: Stop, your highness! Don't! I came to stop you, this will all come to nothing!
Lucifer: So cutie, sit behind me for now while I kick some ass.
He started hitting Avil. Avil tried to fight back, but Luftfer was just toying with him. He wasn't fighting seriously. Avil, however, was fighting seriously. But he still couldn't surpass the demon king.
