The World's Finest Assassin Gets Reincarnated in Another World as an Aristocrat: Season 1

Lugh and his female companions accept a contract to assassinate the corrupt nobles assisting a slave auction, with two of the girls disguised as a slave and a maid. During this time, a flashback of his previous life shows he was training a rookie while simultaneously taking out members of a crime syndicate. 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 wh

The Assassin agreed to kill the Hero simply because he wanted to experience the happiness he could not have in his previous life due to him suppressing his emotions. The Goddess allowed him to choose special powers and abilities, but warned him that he only had eighteen years after his birth to kill the Hero before the Hero brought chaos into the new world. She also told him that there was a slim possibility he could save the world without actually having to kill the Hero. He is then reborn as a

In attempt to measure Lugh's magical potential, Dia gives him a Fahr stone, a special gemstone that can measure a person's magic capacity. Lugh's power is so vast, however, that the Fahr stone ends up exploding. This gives Lugh the idea of using Fahr stones as makeshift grenades. Over the following weeks, Dia and Lugh become emotionally attached to each other. Lugh proves to be an exceptionally fast learner, not only learning how to synthesize metals, but also how to create weapons. He and Dia e

Using his mana vision, Lugh attempts to find someone who can be both his personal servant and his assistant during assassinations. Sure enough, Lugh finds such a person in the form of Tarte, a girl from a poor background, who had made her way to the Tuatha Dé region in hopes for a better life after being abandoned by her family. After rescuing her from a pack of wolves, Lugh brings Tarte to his home and gets permission from his father to train her as an assassin. When he reaches the age of 12, L

Lugh has produced a large collection of Fahr stones thanks to the spells Dia taught him and reports to his father, revealing that all this time, he has been observing Tarte and can say with full confidence that she is not a spy from a rival region. Lugh's father tells him that it is time for Lugh to face him in combat in order to prove he is ready to perform assassinations. Despite Lugh's youth and experience from his previous life, Cian proves to be a formidable opponent. Afterwards, Lugh joins

As Lugh and Tarte begin their lives in the Balor region, Maha and her friends work hard to make a living in the merchant town Milteu. Unfortunately, they are captured by a group of bandits and taken to an orphanage, which turns out to be a front for a prostitution ring. There, all the girls, except Maha, are forced into prostitution under the heel of the local noble, which deeply traumatizes them and even causes one of them, Noine, to scar her own face with a sickle if it means not having to wor

As Lugh continues his life as Illig Balor, he comes up with the idea of opening a cosmetics shop in Milteu in order to both increase profits for the Balor family and fund his assassination duties. He also introduces lotions, moisturizers and sweets to the new world, giving his shop, Orna, a massive boost in sales and a huge advantage in the market in only six months after its opening. However, spies hired by rival businesses attempt to infiltrate Lugh's home to discover the secrets of his succes

Having established a prosperous business in Milteu, Lugh decides to return home and continue his training as an assassin. He leaves Maha in charge of Orna, knowing that she plans to expand the business into other regions, and promises he will come to visit. On their way home, Lugh and Tarte are attacked by a pack of wolves, but Tarte easily kills them and Lugh observes that monster attacks on human settlements have become more frequent, suspecting that the Hero will show up soon. Upon his return

Lugh's first target as a fully trained assassin is Count Azba Venkaur, an aristocrat who has been selling military secrets to neighboring kingdoms in exchange for vizein, a drug that he distributes throughout the kingdom. Using Maha's information network, Lugh decides to investigate the count by himself and determine whether or not the target truly deserves assassination. Lugh and Tarte visit Pisear, the second-largest merchant town in the kingdom, and take down a criminal group selling vizein,

Lugh and Tarte spend a full month on a deserted island as part of their assassin training and upon returning to the mainland, Maha gives them information about a divine treasure, a tool of immeasurable power, that Lugh has been trying to purchase for some time. This divine treasure, a magical spear called Gae Bolg, is in possession of Setanta MacNess, a renowned warrior suspected to become the legendary Hero. Lugh also discovers that the Viekone region is involved in a war and rushes to Dia's ho

Cian explains that it was Dia's father who ordered the assassination on his own daughter as an attempt to stop the civil war currently afflicting the Viekone region. Since the Tuatha Dé family has always had the option to reject missions depending on their interests, Lugh realizes that Dia's death will ultimately fail to stop the war and deduces he can use this mission to save Dia. Tarte, acknowledging Lugh's feelings for Dia, helps him reach the Viekone region in a way that helps him conserve h

Lugh and Dia's father come up with a plan to fake Dia's death and safely sneak her to the Tuatha Dé region. Unfortunately, the arrival of Setanta MacNess thwarts the plan before they can enact it. As Setanta is the wielder of Gae Bolg, Lugh knows that he will not survive a direct confrontation with him, so he fires a magnetically propelled tungsten projectile into the atmosphere and stalls Setanta long enough for it to obliterate him. Afterwards, the Tuatha Dé family adopts Dia under the guise o
