The strongest assassin gets transferred to another world with his whole class

Aragi Kai, a high school student by day and a skilled assassin by night, is despised by his classmates for his aloof demeanor. Suddenly, he and his entire class are transported to a fantasy realm of magic and swords. A woman named Leonora greets them, declaring them “Hero Candidates” tasked with defeating the Demon King. Each student receives a unique Divine Protection—some gain combat powers, while Aragi is granted the ability to analyze others. Mocked for his seemingly useless skill, he secretly leverages his assassin’s expertise and sharp judgment to navigate this new world from the shadows.
