Ghoul ga Sekai wo Sukutta Koto wo Watashi dake ga Shitteiru

A young adventurer named Alice is rescued by Leon, a third-generation hero with the body of a ghoul, during her first dungeon exploration. Despite his monstrous appearance, Leon has a human heart and dedicates himself to killing the monsters that threaten humanity. Alice, impressed by Leon, decides to become his disciple. Leon sees himself as a monster who destroys other monsters, not as a hero. He holds the title of "Savior" in the holy city, the last refuge of humans in a world overrun by dangerous creatures. As the holy city faces the threat of extinction, Leon and Alice's relationship begins as Alice seeks to follow in his footsteps.
