Kai Shinjo lives a double life that most people wouldn't believe. By day, he is the invisible, brooding outcast of his high school class. By night, he is a lethal professional assassin. But everything changes when an otherworldly summoning rips him and his classmates away from their mundane lives and drops them into a dangerous realm of swords and sorcery.

When a mysterious woman named Leonora labels the group as Hero candidates tasked with slaying the Demon Lord, it seems like the start of a typical power fantasy. Everyone expects a grand awakening, but Kai gets stuck with Appraisal—a skill everyone dismisses as completely useless for combat. While his classmates scramble to flaunt their flashy new blessings, Kai isn't bothered. He doesn't need a shiny superpower to be a threat. Equipped with his cold-blooded precision and the deadly instincts he honed in the shadows of the real world, Kai begins to navigate this new land on his own terms. Who needs to be a hero when you can be the one pulling the strings from the dark?
