Saikyou Ansatsusha, Class Ten'i de Isekai e

Kai Shinjo lives a double life as a high school student and a nocturnal assassin, his reserved nature setting him apart from his peers. When his class is suddenly transported to a fantasy world filled with swords and magic, they are told they have been summoned as potential Heroes to fight a Demon Lord. Each student is given a Blessing, but Kai’s ability, Appraisal, appears ineffective. Despite this, he uses his assassin training and calculated approach to operate discreetly in the new environment.
