## Synopsis

The greatest assassin on Earth knew only how to live as a tool for his employers—until they stopped letting him live. Reborn by the grace of a goddess into a world of swords and sorcery, he's offered a chance to do things differently this time around, but there's a catch... He has to eliminate a super-powerful hero who will bring about the end of the world unless he is stopped. Now known as Lugh Tuatha Dé, the master assassin certainly has his hands full, particularly because of all the beautiful girls who constantly surround him. Lugh may have been an incomparable killer, but how will he fare against foes with powerful magic?

His goal is to live according to his own will and obtain happiness, even though he has become a tool of the goddess. He has the mentality to kill whether in his previous life or after reincarnation, but since he was educated by the Tuatha Dé family after his reincarnation, he has some hesitation and guilt about murder. Since he reincarnated with the knowledge and experience of his previous life left behind, he has acquired various skills such as cooking.

He grows into an assassin who can even kill gods by creating a synergistic effect with the skills, experience, and knowledge he inherited from his previous life as an assassin, as well as the secret arts and magic of his family. At the same time, he searches for a "*happy way of life*" that he could not realize in his previous life. He holds the record for being the youngest Tuatha Dé to master the technique and pass the exam (*the previous record holder was his biological father, Cian*).

Lugh possesses all the five basic ranks for skills: S, A, B, C, and D. Merely possessing an S-Rank skill is enough to put someone among the strongest people in the world, making him possibly the most powerful assassin in the world.

 **D-Rank:【***Mysterious ability*】Described as an ability the gods did not intend or don't realize the potential of. Was said to be his final trump card, though the condition and use of this skill will become obsolete if the details of this power are revealed to others; though the Goddess is an exception, as she saw what abilities he chose. Ability acquired from the goddess before complete reincarnation.

> "*Ever since I was born, I've never had such thoughts. However, that wasn't due to a deficiency on my part... It was simply due to ignorance and abstinence. I abandoned my own thinking and simply allowed others to control my body... and pass it around freely.
> I now assassinate through my own will. And I take full responsibility for the significance and reasoning behind each act, and that is why I can keep walking from here on out as well*"

As the best assassin in his previous life, his assassination skills surpassed even his father's in his current life. His knowledge and wisdom combined from both worlds, it was able to help him defeat his father, who was known to be the greatest assassin in their family's history, despite him being much younger.

* Quick Chant - It allows the user to perform multiple incantations at once in quick succession with better efficiency.
* A special magic that is used by Lugh, a (Spell Weaver + Rapid Recovery) This magic is created by Lugh. This skill shines as it allows its user to train with inexhaustible stamina.
* When given the choice of picking his elemental affinity, Lugh chose Total Affinity. This allowed him to use the four basic elemental affinities; Fire, Water, Earth, and Air. The only drawback was that their growth rate would be halved.

* *Earth Magic: Metal Creation* - A technique that generates a gun (with a modern-style rifling) and a bullet (precisely only a warhead. No gunpowder is required because it fires with fire attribute magic) on the spot, and fires with fire attribute magic at any time. Because of the specifications that assume magic, there is no need for a trigger, and it does not exist. It can shoot continuously at the speed of a semi-auto, but it is unknown if it has a magazine. However, there is a high possibility that the magazine does not exist because there is a music college that solves the necessary magic attributes and magical power consumption, and the magazine can be created by adding and changing the technique.
* *Cannons* (with special structures such as materials for increasing power and rifling) and cannonballs (precisely only warheads. No gunpowder is required because they are fired with fire attribute magic) are generated on the spot, and fire can be fired at any time. A technique that bomb is bombarded attribute magic.

As far as the TV animation version was broadcast, the power of the prototype technique's firing exceeded the durability of the gun barrel, and it was damaged with just one shot.
* Also, in the anime version, on top of being equipped with wheels, (because generation is earth magic and firing is fire magic) there is a tendency to depend on the caster for both generation and rapid-fire performance of shooting and bombardment, so generation and Considering the attributes necessary for bombardment, it seems that the technique and functionality are based on the premise of loading other than magic.
 「***Gungnir*** *(グングニル)*」Assassination magic and one of Lugh's strongest attacks. First, Lugh summons a 100 kg heavy tungsten spear. Then, he casts on it an earth spell that alters the target's gravity to give it a negative value (multiplied by -2), making the spear accelerate upward at 19.6 m/s2. After 3-4 minutes (the spear now being 1,023.5 km aboveground), the gravity spell is canceled, causing the spear to free fall on the planet at 4,480 m/s (nearly Mach 14) and generate a massive shockwave and devastating explosion upon impact from the kinetic energy of the projectile impacting at very high speeds.
* Based on the space weapon "God's Staff/rods from God" that was developed in the world of Lugh's previous life it is a matter-based weapon compared to nuclear weapons. The *spell weaver* turned into *dynamic force reversal* magic was used to solve the cost problem of transporting a large amount of metal to the satellite orbit, and the wind magic was used to create the atmosphere. It is an improvement that prevents aerodynamic heating during re-entry. It instantaneously released the energy of 111 shots from a tank gun, it has kinetic energy equivalent to approximately 11.5 tons of TNT (48 GJ).
 「***Railgun***」A superior attack to Cannon Strike and even Gungnir. A superweapon with rifle-sized rounds packing twice as much strength as a tank cannon. Concentrating all of that power into one point boosted the piercing power significantly. With so much kinetic energy contained in an object the size of a bullet, all external elements could be ignored.
* A typically designed as a weapon, that uses electromagnetic force to launch high-velocity projectiles. The projectile normally does not contain explosives, instead relying on the projectile's high kinetic energy to inflict damage, in terms of target effects, increased terminal velocities can allow the use of kinetic energy rounds incorporating hit-to-kill guidance, as replacements for explosive shells made of tungsten.
 「***Mystic Eyes of Tuatha Dé***」A pair of eyes that Lugh acquired from his father through surgery, which allows long-distance vision. Objects in motion appear far clearer and even allow a stronger sense of depth perception. It also allows him to see mana. Normally, mana was something one could only sense, yet now he could faintly make out its flow within his body.
* A secret magic/mystic eye that collects the best of the Tuatha Dé family's medical technology.
* A substitute that was completed under the human experiment of many death row prisoners.
* There are elements similar to skills, but it is a substitute that can be acquired through surgery.
* It enhances general vision and visualizes magic, such as unusual long-distance, night vision, deep vision, and dynamic vision.
* On the other hand, since the amount of information from vision increases accordingly, it takes time to get used to it.

Lugh excels in cooking due to the amalgamation of his previous and current life experiences. In his last life, he had to impersonate a chef to get close to a target; the benefit of this was improved cooking. Because of his father's knowledge about medical, Lugh can performed medical experiment.
