Lugh Tuatha Dé

Lugh Tuatha Dé (ルーグ, Rūgu) is the former master and legendary assassin who was killed by his organization and was reincarnated into House Tuatha Dé by the Goddess to kill the hero, the main protagonist of the series. In his previous life, he was touted to be the best assassin in the world.

Appearance
He has spiky silver hair and silver eyes. He wears an assassin outfit that looks like a normal aristocrat dress. During his youth, he was described to be handsome and had many girls and proposals chasing after him.

A crimson aura flows in his left eye whenever he is ready for battle or assassination.

Personality
As a master assassin from his previous world, he is ruthless in killing his targets. He has shown a calm and collected demeanor even during life-threatening situations. This façade only falls apart whenever any of his fiancées tease him, especially Maha. He is described to be a kindhearted person as shown when he saves Tarte from dying alone in the cold and telling her he needed her. He saved Maha and Tarte from dreadful situations, gave them a purpose, and raised them to be capable people even without him present. Despite being tasked with killing the hero, he actively looks for an alternative to save her instead, empathizing with the hero for the pressure put upon her by the world.

He is a sharp person who can easily figure out people's true intentions, even if the other person is a supreme deity like the Goddess. He can also easily manipulate any person and gain their trust. Despite being a wise person, he is seen by many who know him to be a very dangerous person. His motto is to avoid killing innocent people and to annihilate the entities who would or might come in the way of his mission of killing (or saving) the hero.

He is always shown to be proactive and knows how to take advantage of the situation, such as when the Headmaster gave Lugh and his group a mission to befriend the Hero and gain her trust. He is extremely wise thanks to the experiences of his prior lifetime and knowledge gained from the present world; however, because of that, there are times where he overestimates his own abilities, to which he acknowledged that he still has much to learn. He is also an accomplished cook and dancer, which are skills he learned and cultivated.

He can be a little dense when it comes to women's feelings towards him, like those of Maha and Tarte, mistaking their affection for admiration. He was open to their affection after realizing that he uncharacteristically got angry at anyone who approaches them in the wrong manner. After experiencing his first "nightly emission", Lugh made it a point to go to brothels to release his pent up sexual tension, rather than accepting Maha and Tarte's offers of sex; not wishing to make them feel like it's all they're useful for. Though he does later learn Tarte was hurt by his choice; believing her physique wasnt attractiveness enough. He does start relenting after consummating his romance with Dia.

Even after his reincarnation by the Goddess, he still retained his old personality and his knowledge from his prior life as an assassin in his previous world, but as he became an assassin for the Tuatha Dé, his inner personality suddenly started to change as his life story progressed; although he was able to manipulate both those who were weaker than him and those who had a harsh childhood or youth to join his side and work for him, he treated them like his own family (brother/sister) and friends since in his world he treated his subordinates and himself as a tool for the organization before his assassination on the plane with his apprentice and he is currently trying not to repeat such actions. This is especially due to the fact he swore a lifelong oath to protect the innocent, his family, his friends and those who loyally work with him like Epona, Maha, Tarte and Dia. This is where he began to have a moral conscience regarding his life work after his father Cian taught him about justice and their work as assassins for humanity and other noble causes, though he will not hesitate to kill his allies if they betray him and his family.

Background
In his previous life, Lugh was an elderly man known as the world's greatest assassin and was expecting to retire and become an instructor for recruits after one last mission. Throughout his time as an assassin, he has employed uncountably various and different tactics to achieve his objectives. In the past, he has even used his body as a form of seduction to assassinate his targets.

On his way back, he realized that the assassination organization doesn't need him anymore and wanted to eliminate him by causing his plane to crash. That only saddened him as he had always been loyal to them and would have even taken his own life if they had told him he was no longer needed.

As he died, he was transferred to a different realm where he met a Goddess who offered him to reincarnate with a new life or retain his memories and knowledge and reincarnate in a different world, where he must kill the hero. Wanting to live for himself, the man agrees to the second offer, chooses his skills, and is reincarnated as Lugh Tuatha Dé, heir to a clan of assassins.

Skills
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.

Master Assassination
As the best assassin in his previous life, his assassination skills surpassed even his father's in the current life. With 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.

Rapid Recovery
S-Rank : 【Rapid Recovery】 Increases the recovery rate of the user's stamina, mana, healing, etc. The recovery rate is increased by a factor of 100. This multiplier can be increased with training. Ability acquired from the goddess before complete reincarnation. Lugh reasoned this was the best choice in order to match or exceed the hero's own stamina.

Beastification
Granted by Epona.

S-Rank : 【Beastification】 When invoked, it transforms the user into a half-beast. The skill grants the user the Idiosyncratic abilities pertaining to their animal while also enhancing their physical senses and capabilities.

My Loyal Knights
S-Rank : 【My Loyal Knights】 Grants the ability to give some of one's skills to exactly three people. Once each person is a "loyal knight", the blessing would be revoked if they ever lose a battle or if they deny an order made by the master. The skill can not be given a second time to the same person. Through this skill, he is bound to the hero while also receiving much of her innate strength.

Multi-Chant
S-Rank : 【Multi-Chant】 After obtaining My Loyal Knights Skill from Epona, Lugh attained a S-Rank called Multi-Chant. It allows him to perform multiple incantations at once.

Spell Weaver
A-Rank : Described as the ability to invent new spells, granting limitless possibilities. Ability acquired from the goddess before complete reincarnation. Lugh saw only having access to 100 spells as a handicap; so he decided on a creation of his own spells to give him an edge.

Squire's Devotion
A-Rank : 【Squire's Devotion】 While this ability is active, every ability of both the user and the master is greatly enhanced. Additionally, should the master die, the user can revive them in exchange for their own life. It also allows Tarte to telepathically contact Lugh up to a range of 200 meters.

Martial Arts
C-Rank : 【Martial Arts】 Grants excellent hand-to-hand combat capability and enhanced reflexes. Ability acquired from the goddess before complete reincarnation. Lugh reasoned an assassin needed hand to hand combat skills; kills won't always be single long-range strikes on targets.

Quick Chant
It allows the user to perform multiple incantations at once in quick succession with better efficiency.

Mysterious D-ranked 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 is revealed to others; though the Goddess is an exception, as she saw what abilities he chose. Ability acquired from the goddess before complete reincarnation. D rank called Dick god he can impregnate every creatures he fuck even women gods

Cooking
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.

Magic Attribute
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 drawbacks was that their growth rate would be halved, as well as not having an affinity for the rarer elements of Light and Dark.

Normal

 * Earth
 * Wind
 * Fire
 * Water

Spell Weaver + Rapid Recovery
This magic is created by Lugh. This skill shines as it allows its user to train with inexhaustible stamina.

Gun Summoning / Gunfire
This magic can be used by many but in the case of Lugh, he can summon a large number of guns (including cannons like those he use during Cannon Strike) at once with massive firepower that is capable of destroying a mountain.

Cannon Summoning / Bombard / Cannonfire
Lugh summons a cannon that fires a round the size of milk bottle that flies up to 500 meters away. as noted by Dia Viekone that nothing will be left of someone that takes the hit head on.

Cannon and Rifle Volley
During Volume 2 Lugh created another Anti-Hero Spell that rivaled gungir in firepower. Rifle volley is when Lugh summons 2 rifles or cannons of varying sizes as lugh once summoned rifles that are normal sized, and rifles the size of cannons, or straight up large cannons. The spell is first casted with the spell "Arrange" which positions them behind or near Lugh all aiming towards his target. Powered by fahr stones that wiped out an entire goblin and orc army.

Gungnir
One of Lugh's strongest attack. 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 minutes (the spear now being 1,023.5 km aboveground), the gravity spell is cancelled, causing the spear to fall back on Earth at 4,480 m/s (nearly Mach 14) and generate a massive shockwave and explosion upon impact. An alternate version of this spell was used in Volume 4 when lugh used the spell on the beast God Riogel, but instead of sending a rod to orbit, He sent the beast god to orbit, and in volume 6 he used the spell on himself to breach the holy land.

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.

Mystic Eyes of Tuatha Dé
A pair of eyes that Lugh acquired from his father through surgery, which strengthen his eyesight and allows for long-distance vision a greater distances, dynamic visual acuity (objects in motion appear far clearer), depth-perception, and low-light vision. It also allow him to see mana, which normally was something one could only sense, yet now he could make out its flow within his body and perceive it in other people.

Dia Viekone
Lugh first met Dia as his teacher in the ability to use magic. She was impressed by his skills with magic. Learning that they can create new magic together, she started to get interested in magic even more and every new magic creations deepened the bond between herself and Lugh. During her short stay with Lugh, she would often feel lonely and come to Lugh's bed and use him as a body pillow to fall asleep. Being older than him, she liked to think of herself as Lugh's big sister, but instead, she became something akin to his little sister in many situations.

She is Lugh's main love interest throughout the series. Nonetheless, she is not too possessive of him and allows him to have a few mistresses, although she does not want other girls to make a move on him before she does, as shown when she finds out that Lugh had already kissed Tarte many times, even though it was for healing. She has made it clear that other than Tarte and Maha, she would be greatly upset if he cultivates any more romantic relationships. Due to her close relationship with the other fiancées, she actively supports his relationship, but would still get jealous and lonely from time to time.

In volume 3 she had her first time with Lugh in a love hotel in Milteu.

Tarte
Lugh's first assassination assistant, Tarte is a mage saved by Lugh who wholeheartedly entrusts herself to her savior. Even though she had gained Tuatha Dé's trust, Lugh had sworn to kill her if she turned out to be a spy or a traitor, but he sincerely believes in her. She hates anyone who speaks ill of Lugh and would not hesitate to kill such individuals. Lugh sees her as a potential partner who will never betray his trust.

She is shown to have strong romantic feelings for him, and even dreams of Lugh doing perverted things to her, to which Lugh is fully oblivious. As of volume 3, after Tarte asked for him to give her an actual kiss rather than their normal routine, he gladly did so, requiting her love for him.

Maha
Lugh's adopted sister, Maha is yet another mage saved by Lugh's actions, although, at that time, he was known by his alias, Illig Balor. She serves as the CEO of Lugh's cosmetics brand whenever Lugh is absent. She is also trained by him in assassination and torture. She always helps him in every way possible despite their limited time together, even it is for an assassination. He gave her the sole authority of managing his brand, fully trusting her capabilities, even supporting her action of adopting children with a poor background. However, after realizing he had inadvertently placed too much pressure on her, despite Maha not complaining, he helped lessen her loads.

Lugh admits that out of anyone, Maha was the only one capable of having him around her thumb, admitting she was the best though not elaborating in what way. Her appearance and demeanor are the most woman-like of his fiancées. After the son of Balor proposed to her and asked for Lugh's blessing, he uncharacteristically got jealous. Noticing his subtle change, Maha rejected the proposal despite potentially being the most influential and richest woman in the world, and getting back her father's company. She explains that "I'm yours" to Lugh and teased him for getting aggravated on her behalf. Lugh knew that he should think more of Maha soon as if he continues to procrastinate on the matter, she might eventually be taken away. They have gone on numerous dates together and even shared a couple of desserts, feeding one another, much to Lugh's embarrassment.

Like other girls, she also has romantic feelings for him that she made clear since volume 1. In volume 2, Lugh kissed her on the cheek twice after she requested it despite not expecting him to go through with it. She was happy yet embarrassed by the action, pouting during the date that she might not focus on work on that day. After collecting herself, she ended off by saying that she should be more adventurous next time since he was already willing to go to this extent for her.

In volume 3, she warned him that if he doesn't keep her close, she might run away. Fearing such a dreadful possibility, he asked if there was any way that he could avoid it. Cheekily she told him that there was only one way of tying down a woman to which he quickly changed the subject. Having her fill, she continues by saying that she's a patient woman though she won't wait forever, which Lugh took her warning to heart.

Goddess
Lugh doesn't trust the goddess.

Epona Rhiannon
Lugh was tasked with killing Epona. That being said he was willing to befriend her to prevent the world's destruction.
