Anti-hero at the Bottom of the Job Caste System

In a world where the value of existence is determined by occupation (class), the protagonist awakens to the skills of a “thief” and is persecuted as a “harmful designated class”. One day, he is saved by Aoi, the head of Shinobi Street, a town where people who are also persecuted gather, and decides to become his friend. However, the peace is fleeting, and the city of Shinobi is attacked by a mysterious group, and his friends are killed one after another. At that time, Hitoshi’s skill, which he could only watch, awakens and acquires the “skill to steal the skill of the dead”. Hitoshi uses this skill and vows to take revenge on the mastermind who killed his friends.
