F-Rank and Kicked From My Party, Now I'm Being Trained as the S-Rank Succubus's Pet
(2025)A novel by Leon Kageyama
They threw me away. She picked me up. Now, my power is hers to command.
Kicked from my party and left for dead in a gutter, I was just another F-rank failure. Then she found me. Lilith. An S-rank adventurer of terrifying power and ungodly beauty. Her offer wasn't salvation. It was a contract, whispered with a predatory smile: serve her, and she would grant me a purpose.
My new life is a grueling series of "training" sessions designed to shatter my limits and reshape my will. Lilith’s methods are unconventional, her demands absolute. She seeks to forge me into the perfect instrument for her power. But in the crucible of submission, a unique, world-breaking talent awakens within me. I am no mere servant—I am a Resonance Catalyst, a living amplifier who can magnify my master's demonic power to godlike levels.
Our dangerous alliance is challenged by Ephilia, the Saint of the Blade, a holy knight sworn to save me from my dark pact. Yet the more she witnesses our dynamic, the more her righteous fury twists into a dangerous, obsessive curiosity. Worse, a ruthless hunter from Lilith’s ancient past emerges from the shadows—an enemy armed with a sacred power designed to unmake demons. He is here to erase my master from existence, and I, her force multiplier, am all that stands in his way.
From the weakest link to a Demon Lord's ultimate weapon, this is a dark power fantasy about forging strength in the fires of absolute submission and loyalty.
This novel is intended for mature audiences and contains explicit scenes, an overpowered protagonist (eventually), a dominant Demon Lord heroine and unconventional power dynamics.
