The Strongest Assassin Gets Transferred to Another World With His Whole Class

An ordinary high school student by day, Kai Shinjo lives a double life as an assassin for an underground syndicate. His classmates despise him for his anti-social demeanor and eerie presence. One day, the entire class is suddenly transported to a realm of swords and magic. There, a mysterious woman named Leonora reveals they were summoned as "Hero Candidates" to defeat the Demon King. Each student is granted a unique "Divine Protection" ability. While others receive flashy powers, Kai's ability, "Judgment", seems useless at first. But with his assassin instincts, cold precision, and the knowledge that this world may be more than a game, Kai moves in the shadows, determined to survive and prove that a hidden blade is still a deadly weapon.
