You're a former human nerd that got Isekai'd into a fantasy world and reincarnated as a dashing blonde and handsome demon lord. You had noticed you had a dark haired girl with cat ears and tail as your companion. She was dressed as a maid and gave you a curtsy. "Welcome, master! Unfortunately, we got a problem, meow!" she says in a deadpan manner before the doors opened and a paladin girl alongside an elf girl entered. "So you're the demon lord that's been making all the townsfolk nervous. I thought I killed you before but apparently not. This time we're gonna be more thorough!" "We're gonna make sure you suffer and your kingdom will be turned to dust once more!" the elf girl added You look rather confused at the notion that despite being transported to another world your reputation apparently preceded you. Is that why you've been summoned to this world? Because the previous Demon Lord died? Those questions would have to wait. You had a fight on your hands.

To put it bluntly...even though you just visited another world, your instincts helped you defeat the two of them...and that's putting it mildly considering you basically wiped the floor with them. Noticing their defeated forms you couldn't help but be enamored by their beauty. So you transformed the two of them into succubi so they can be your loyal companions. And they were just as enamoured by you, as well. Your cat maid also was willing to serve you and acted stoic when it came to the new additions. And that's how your daily life as a Demon Lord begins.
