Lugh

Lugh is a thief who possesses three legendary treasures, as well as a member of Iscariot opposing the Magic King. Initially appearing during Iscariot's assault on the Royal Bilbia Academy, Lugh has since become both an enemy and occasional ally to Arata and the Trinity Seven.

Personality
Lugh is a very candid and nonchalant young woman who often appears emotionless, although not quite to the same degree as Arin. She herself has noted that she has never been good at expressing emotions. Furthermore, she can be quite incongruous and oblivious to current events. After Levi craftly used a hoax of her Final Spell, Lugh would not realize Levi's deceit until after Master Liber revealed that she had been fooled. Nevertheless, Lugh is dedicated and loyal to her goals and allies, willing to fight and support them in dangerous times. She has shown genuine concern toward her comrade Hijiri, once defending her against an attack from Akio. Moreover, Lugh has even aided her enemies, choosing to continue supporting Arata in his clash against Abyss Trinity.

However, despite her seemingly impassiveness, Lugh has displayed various emotions on certain occasions, such as becoming embarrassed in perverse situations. Following Arata accidentally falling on top of her and touching her chest, she was quite flustered and even more surprised after he ignored her afterwards. Additionally, as a thief, she has a great love for treasures, able to sense them even if their presence is hidden. Lugh would even become willing to marry Arata so she would inherit his treasures as his wife. She also been shown to have a mischievous side, sometimes acting in a crafy and humorous manner. In once instance, she would attempt to defeat Arata after defeating the patrollers in Sky Library as promised.

Lugh has a great deal of confidence in her combat abilities, even ranking herself as the second strongest person in the world. Throughout battles, she usually remains as her calm self, able to quickly ascertain enemies' aptitude, as well as decide on the best course of action to fight. After being trapped by Selina and Lieselotte's magic, she would choose to break one of her legendary treasures to escape as her better option despite the decrease in strength. Lugh can also be quite ruthless sometimes, willing to use extreme and violent force to defeat her enemies. During her assault on the Royal Biblia Academy, she would significantly incapacitate Levi causing serious damage, as well as nearly killing Selina. Due to her great strengths, Lugh can be arrogant on some occassions, however, she can also be greatly surprised by unexpected events.

History
Some time ago, Lugh managed to sneak into the Sky Library and steal three legendary treasures, becoming a Magic King Candidate. She would also eventually join Iscariot where she met Master Liber and Hijiri.

Assault on Biblia
She battled Levi while the other members of the Trinity Seven were at the Royal Liber Academy. When she defeat Levi. When she was bound by Liese, she overloaded her [Virtus Arm] "Light Piercer Brionac." She had to chose between either breaking one of her weapons or continuing being unable to move.

Ildanach
Known as the "God of Light", Lugh is a master of high-speed "Luminescence" or Ildanach from the Invidia Archive, as well as a Magic King Candidate. Considering herself as the second strongest person in the world, she was even described by Yui as stronger than the Trinity Seven. Lugh's Ildanach magic allows her to become the "equivalent of light", able to move at the speed of light. As such, she is able to evade almost any physical attacks from touching her. Furthermore, her quick reflexes helps protect her from ambushes, capable of  fending off sudden surprise attacks from Levi and the Royal Akasha headmaster.

Additionally, Lugh is very skilled swordsman, able to wield a katanna in each hand proficiently during skirmishes. Along with her Ildanach magic, her swordsmanship becomes more difficult to defend against, being able slice through anything at the speed of light, as well as split herself into multiple copies to perform simultaneous strikes instantaneously. During her tag team battle with Hijiri against Arin and Yui, Lugh easily shattered Yui's magical defense.

During battles, Lugh usually possesses a calm and collected demeanor, generally able to quickly rationalize her next move in battle. During her fight against Levi, she determined against using a "Last Crest" that risked the user's life was unnecessary as she was a Magic King Candidate. Lugh also possesses a strong sense for treasures, able to detect their locations even if they are hidden.

However, Lugh's Ildanach magic is notably weak against Lieselotte's and Selina's Logos Art magic, particularly the latter's binding spell which can imprint "a single moment of light onto film". Another method that has been proven to be effective against her is trapping her from all directions to prevent her from moving, as demonstrated by Levi's Final Crest hoax, and later her use of threads.

Mythical Armaments
Stolen from the Sky Library, Lugh posseses three legendary treasures, available only to those who have mastered a thema, which allows her to fufill the conditions to become a Trinity. Upon summoning the Mythical Armaments, Lugh's speed and power becomes greatly enhanced. She was able to substantially wound Levi instantly without the latter's realization, as well as forcibly removing Selina's binding spell quite easily. Lugh herself has commented that she can never seem to fully control her strength when in this mode.

However, if any of the armaments become destroyed, Lugh becomes unable to summon then for a while.

Iscariot
Hijiri Kasuga - As a member of Iscariot, Hijiri is a comrade of Lugh with the same objective of stopping the Magic King. The two seem to get along very well with one another, treating each other in a friendly and respectful manner. Lugh, in particular, seems to care for Hijiri's well being, becoming concerned over her unstable health and even willing to fall along with her if she ever tripped, much to Hijiri's astonishment. She would attempt to defend Hijiri from an attack from Akio, eventually leading to her capture. Although, on other occasions, Lugh has also been shown to be sometimes intimidated by Hijiri's behavior, once becoming frightened during Hijiri's first meeting with Anastasia-L. Nevertheless, Lugh and Hijiri both appear to care and trust one another. Notably, their teamwork has been described as focusing on the offensive.

Royal Biblia Academy
Arata Kasuga - As a Magic King, Arata is an enemy of Lugh, a member of Iscariot. In their first meeting, Arata accidentally touched her breasts after suddenly landing on top of her during Iscariot's assault on Biblia. Embarrassed by their initial encounter, Lugh would become surprised by Arata's later nonchalance to the event, as well as mistake his action as an attempt to make her his mistress. The two would later again meet during their mission to Sky Library, where they would mostly get along despite being adversaries. Even after Lugh attempted to betray him, Arata would continue to treat her in a friendly and jestful manner. Lugh would also begin to become more accepting towards Arata, supporting him in his battle against Abyss Trinity. Notably, after Arata gained possession of Judecca, Lugh declared that she would become his wife, as the husband's belonging would also belong to the spouse.

Trinity Seven
Levi Kazama - As members of Trinity Seven and Iscariot respectively, Levi and Lugh are adversaries due to their individual own views of Arata, the Magic King. First encountering one another during Iscariot's incursion on the Royal Biblia Academy, Levi would fight against Lugh to protect the school albeit with great difficulty. Lugh, while considering herself the superior fighter, would come to respect her skills and abilities, causing her to becoming serious for their battle. Likewise, Levi would also treat her in a courteous and friendly manner, as well as acting crafty during one portion of their skirmish much to Lugh's confusion. Even after being defeated, Levi would not seem resentful and continue to behave amiably as always.
