Summary
The story begins with a human auction, where young girls are sold off to wealthy old men under the watchful eye of Marquess Collide. Under the command of the kingdom, Lugh Tuatha Dé began to investigate Marquess Collide with the help of the mage Dia Vicorne, his assistant Tarte, and his intelligent sister Maha. Dia and Tarte, who had infiltrated the auction as a slave girl and a maid respectively, start killing the auction’s attendees and staff, and set the enslaved girls free. After that, Marquess Collide tried to run away and save herself, but Lugh and Maha managed to locate and snipe her from afar.

After this, a flashback of Lugh's previous life as the greatest assassin in his former world is shown, where he was taking out members of a crime syndicate along with his rookie assistant. After killing the targets, the Assassin decided to depart, but his rookie assistant suggested that they should kill every single criminal on sight, but the Assassin replied that they were only hired to kill specific members so he will depart now. As they tried to escape, the Assassin and the rookie were intercepted by a drone, which forced them to improvise in order to avoid it. As day broke, the Assassin contacted the organization where he announced his intent to retire and become a mentor to future assassins in Japan. Using fake passports, the Assassin and the rookie reached a nearby airport and took a flight to Japan. Unfortunately, their plane was attacked by a fighter jet deployed by the organization, and the Assassin realized that he had been set up. The Assassin first thought that he could save himself but then sees that a missile is launched to destroy the airplane during its course. Once the Assassin died, he encountered a Goddess. The Goddess gave him two choices. First, to be reborn as a completely different person, and second, to accept her request and be reborn with his memories intact to assassinate a hero. The Goddess wanted the Assassin to take the second choice because she needed him to kill the Hero of another world.
