Synopsis

A figure from the protagonist's past life appears, seeking vengeance for their previous death at his hands. The protagonist, now much stronger, refuses to fight, instead forcing his former foe to make a public confession of his past wrongdoings. Following this, the protagonist is informed of a unique and challenging dungeon inside an existing one in Los Angeles and is requested to investigate it, with the local parties requesting to purchase the loot while also hoping to learn the protagonist's fighting techniques. It is revealed that the dungeon houses a drake almost at a dragon level that the local players failed to conquer.
