Ghoul ga Sekai wo Sukutta Koto wo Watashi dake ga shitteiruグールが世界を救ったことを私だけが知っている; Only I Know the Ghoul Saved the World

“I’m not a hero. I’m a monster that devours monsters.” In a chaotic world where ferocious monsters run rampant, there was a “monster” who inherited the title of “hero” in the holy city, the last bastion of humanity on the brink of extinction. Alice, a rookie adventurer, was attacked by a large pack of dog people (Kobolds) during her first ‘dungeon’ exploration. The one who saved her life was Leon, the third-generation “Savior” hero, who, despite having the body of a monster (Ghoul), possesses a human heart. “I’m nothing but a defiled ghoul who keeps on killing monsters.” “No, you’re the only hero who can save the world.” For some reason, Alice, who admires him, applies to become Leon’s disciple.
