High school student by day, by night an underworld company assassin. He has a taciturn personality and an eerie vibe, and his classmates hate him. One day, without warning, Araki and his entire class are transported to another World. A world of sword and sorcery. During their confusion, a woman by the name of Leonora arrives and tells them, "You are Hero Candidates summoned to defeat the Dark Lord. Please help us." Leonora bestows each of them with special abilities. Amidst powerful blessings like telekinesis and explosion, the blessing granted to Araki is Appraisal. It allows him to view the specs of his target, but, partially because he was already ostracized by his classmates, they mock him for having a skill that's useless in combat. However, as a skilled assassin with the ability to calmly assess the situation, he begins to move behind the scenes in the other world too.
