The students, all of whom are skilled in various forms of combat and espionage, are divided into classes based on their proficiency and specialization. The narrative primarily follows a group of students in Class 7, considered the lowest-ranking class due to their perceived lack of talent. Despite their underdog status, the members of Class 7 possess unique abilities and unconventional methods that set them apart from their peers.

The protagonist, a seemingly ordinary student named Kaito, is revealed to have a mysterious past and latent skills that make him a formidable assassin. Kaito’s calm demeanor and strategic thinking often place him at odds with the more aggressive and competitive students in higher-ranked classes.
