A pair of girls brazenly interrupts a human trafficking auction organized by a marquess. Sniper Lugh puts the escaping marquess in his crosshairs.
After the assassin accepts the goddess's request to kill the hero and chooses his skills, he is reborn into a new world and given a name: Lugh.
Lugh begins learning magic under the tutelage of the genius mage Dia, who marvels at his incredible potential before teaching him his first spell.
Lugh continues his search for someone possessing mana. Later, he goes hunting in the woods, where he finds a little girl beset by hungry wolves.
After a special test, Lugh's father Cian takes him along on assassinations as he guides him toward becoming a full-fledged member of House Tuatha Dé.
Maha and other young orphan girls without a home eke out a living in a mercantile city. One day, they are abducted and forced to work in an orphanage.
Entrusted with running a shop by the Balor Trading Company, Lugh begins making and selling a moisturizer that quickly becomes a popular product.
Having found success and built many connections through his cosmetics brand, Lugh leaves Maha in charge and returns to his family home with Tarte.
With Tarte in tow, Lugh heads to a merchant city to investigate whether his target — an aristocrat suspected of drug trafficking — deserves to die.
Learning that Dia's family is involved in a civil war, Lugh rushes to her side. Seemingly unfazed, she asks him to take her into town for the day.
Lugh is tasked with an unexpected request from Count Viekone: assassinate his daughter Dia. After pressing Cian for details, Lugh accepts the job.
Before Lugh can enact his escape plan with Dia and her father, a powerful, spear-wielding knight attacks the castle and challenges Lugh to a duel.
