His Mistress is His Ex-Wife - Chapter 299: Partners in Crime

This legend tells the tale of the protagonist, Kuroki summoned to protect the demon king from the hero.

Kuroki, unbeknownst to him, suddenly came to another world. He was summoned by the demon king, Modes. The territory which the demon king overrules was in the midst of being destroyed because of the hero. He had no choice but to bow before Kuroki.

“Please save us, Savior Dono!”

Kuroki nodded, deciding to save the demon king due to an unexpected turn of event.

The story begins similarlly—a mid-level corporate worker dies and awakens in another world as a 19-year-old—but from there, Eren follows a very different path.Erik, a mid-level office worker, had a simple dream:“Graduate college.Get a job.Screw MILFs.”But reality wasn't so kind to him. Due to his hastiness, he forgot to check the company's background and accidentally enlisted himself into a black company—a corporate hellhole that literally made employees work to death.Such was the fate of our protagonist, Erik.Exhausted after working nonstop 12-hour shifts for seven days straight, he lost his grip on reality and met a meaningless death, collapsing onto his desk in an office nobody would mourn.Yet, reality wasn't entirely cruel either.He suddenly transmigrated into the body of an 18-year-old—young, energetic, muscular, and brimming with vitality. And best of all?He woke up sleeping right next to someone!“What? I'm transmigrated sleeping right next to my step-aunt?!”Even crazier: in this new world, beauty standards were completely reversed. Here, the pinnacle of femininity was a skinny figure with small boobs and an even smaller ass, and women who didn’t fit that mold—busty, curvy MILFs—were mostly ignored, discarded, and lonely.“How crazy is that?” Eren voiced, grinning from ear to ear.But all of that was about to change, since he was here now. He'd make all MILFs his—starting with his deliciously thick, step-aunt.

In a world where Spirit Summoners bond with legendary heroes to save civilization, I awakened as F-Rank—the absolute weakest.While my classmates summoned knights, saints, and mythic champions, my summoning glitched. The circle turned red, and when the smoke cleared, I was staring at the Tyrant Empress—a Calamity-tier villainess who nearly destroyed the world 800 years ago.Everyone calls me cursed. Dangerous. A threat that should be eliminated.They're right to be afraid.Because the Tyrant Empress wasn't the only one who answered my call.And unlike the others, my strength is forged in pleasure.Through forbidden dual cultivation with my villainesses, I grow without end.My name is Cade Marlowe, and I don't summon heroes.I only summon villainesses.
