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.
