Torture Princess: Fremd Torturchen

Kaito Sena has endured nothing but hardship for as long as he can remember—and even death refuses to grant him peace. Just as his bitter life reaches its end, he finds himself summoned by Elisabeth Le Fanu, the infamous figure feared as the "Torture Princess." Before her, Kaito is confronted with a brutal ultimatum concerning his second life: he may serve her faithfully as her personal butler, or he will be subjected to a long, agonizing death by torture. Faced with such a merciless choice, Kaito has little option but to pledge himself to her side. Now bound as the Torture Princess's butler, he accompanies Elisabeth on a relentless campaign, their shared purpose nothing less than hunting down and eliminating the fourteen ranked demons whose devastating power has plunged the world into chaos and ruin.
