Royal Officer AcademyEdit
The First Princess of the New Kingdom Atismata and Lux's friend and fellow classmate. In their initial encounter, Lux accidentally bumped into a naked Lisha that led to his temporarily arrest under her decree. Due to the downfall of his former empire, Lux was initially belittled by Lisha and the two dueled in a mock duel, where they were interrupted by an Abyss but Lux managed to rescue her from harm. After the duel, Lux became the first person to see Lisha's belly tattoo that resembled Arcadia Empire's insignia, reminding him of the Old Empire's atrocious acts towards her, garnered his sympathy. Nonetheless, both later become friends as they study in the same class. Lisha planned on having him act as her personal knight. During Velvet Barth's attempted rebellion, Lux protected Lisha from Velvet and defeated the usurpers easily. In the process he exposed his secret identity as the Black Hero to Lisha but she kept it hidden from the public, further solidifying their bond. Lisha is also responsible for Lux's Drag-Ride's upgrades, including his Bahamut. He also said that it's okay if the people of their country or the people of the whole world would not accept him, since he can fight as long as he has Lisha's acceptance.
A mysterious noblewoman who hailed from Einfolk House of the Ymir Theocracy. She captured Lux after the bath incident. She then tooknotice of the fact that he carries two Sword Devices, and that one in particular is black, prompting her suspicions towards Lux as the Black Hero. During his welcoming party game, Lux hid inside the girls changing room where he accidentally saw Krulcifer in her underwear, but she also took advantage of the situation to make him serve her for a week. During the week, Lux had to work as Krulcifer's "boyfriend" in an attempt to remove herself from the interest of suitors set up by her adoptive family. During a mission to the Ruin Garden, Lux learned the truth about Krulcifer' as one of the Ruin's few survivors but that doesn't stop him from protecting her from harm. This became more evident during his later duel against Balzeride for her sake. Since then, Lux has become Krulcifer's tease subject and love interest.
The Einfolk Household initially had a poor first impression toward Lux (by this time the Seven Dragon Paladin representing The New Kingdom). After Mel Gizalut kissed Lux's cheek, she then explained the Einfolk Household's decision about the engagement. Even though they scolded Krulcifer because of her awful prank, the Household praised her for choosing Lux to be the candidate and they now approve of the two having a relatioship.
Lux's childhood friend and fellow classmate in the Royal Officer Academy. Seven years ago, Lux met Philuffy and played a lot together because of the Aingram House's association with Lux's mother. Due to that relationship, especially when Philuffy was one of very few who sympathised with Lux after his mother's death, Lux and Philuffy have a very close relationship together. They usually address themselves via their nicknames: "Lu-chan" and "Phi-chan". Additionally, Philuffy was the reason Lux staged a coup against his very own country, as he wanted to prevent her becoming one of Old Empire's experimental subjects.
The Royal Officer Academy's principal who is also Philphie's older sister and Lux's acquaintance. Due to a longtime friendship between the Arcadia and Aingram families even after the former's downfall via a coup, Lux was spared from his imprisonment and he joined the Royal Officer Academy under Relie's recommendation.
The academy's strongest student and one of Four Great Noble's prestigious member, who was also infamous for hating men. Unlike most students, Celis strongly opposed Lux's enrollment in the academy at first, despite him saving the students during her absence. Lux interacted with Celis under his cross-dressing moniker as Luno, at one point going shopping and having a picnic together. He realized that she is a normal girl behind her proud demeanor, and her "man-hating" reputation was actually due to her lack of interaction with men aside from her father. In a mock duel between both Lux and Celis, which is later interrupted by both Poseidon and Heiberg Republic's plot (with Celis' friend Saniya being revealed as a spy), Lux protected Celis from harm while learning that his grandfather's (Wade Roadbelt) died as an unintended consequence of Celis's actions. He forgave Celes and claimed that he would never hate her.
Lux and the Triad have a mutual respect for one another. The Triad are usually friendly with Lux after his enrollment into the academy. They even brought gifts for him while he was in the hospital, which he later repaid them by buying them gift afterwards. Lux trusts them enough to asks them for help when he went to fight Balzeride Kreutzer, even revealing his identity as the Black Hero. However, like most of the girls at the academy, the Triad don't mind making Lux perform requests for them. One request involving Lux having to wear a girl's uniform during a watch-out, excusing it as for the sake of the academy and not for their personal interest (which it was). While the Triad don't seem to hold any romantic feeling for Lux, they enjoy teasing him about how popular he is and the situations he get's into with the other girls.
In the light novels, there are more hints towards the Triad girls having a romantic interest in Lux as in many events the tend to blush from his actions as well as show jealousy whenever other girls are being intimate with Lux.
Lux's younger sister and one of his surviving siblings following the fall and demise of the Old Empire. Due to her unknown illness, Lux is willing to do anything for her sake even when he had to be chore prince for the kingdom. However, his selflessness and benevolence worries Airi as she view that his very attributes would cause him into some troubles that even nearly endanger his life. Additionally, Airi is among the few who knows Bahamut's strength and weaknesses.
Aeril is Lux's distant relative. Over 1000 years ago, Arcadia house was divided into main family and branch family. Along her sisters, Aeril was the last survivors of main family, 13th generation. Pioneers of Lux who was from branch family rebelled against Mmain family, the branch family then revived Empire Arcadia (Arcadia Teikoku) which Previously, its name had been Holy Empire of Arcadia (Shinsei Arcadia Shokoku).
She was initially disguised Coral Esther, an aide of Greifer Nest from Vanheim Principality. At first sight, Lux somehow got attracted to her. However, she who disguised as a bishounen technically was a beautiful bo. As Coral, she aided Lux a lot during his position as one of the Seven Dragon Paladins because she viewed him as a kind, upright, and strong boy.
During Holy Arcadia Empire Arc, Lux was betrayed by Aeril when the latter drugged the former and, like his fellow Dragon Paladins, being abducted to the Holy Arcadia Empire. In the same arc, she was also given a "right" to use Lux by her elder sister Listelka who then noticed her little sister's affection towards him. As the story progresses, however, Aeril eventually turned against her sisters and aided Lux in his battle against her former allies.
The vice captain of the Dragon Paladins and also Lux's rival. Despite being fellow Dragon Paladins who have survived the infamous Baptism and having a mutual hatred towards Fugil, they have conflicting ideologies. Whilst Lux wishes to save everyone he holds dearly, Singlen on the other hand wishes to rule the world through apathy towards others. For the most part, their hatred against each other are mutual: Lux loathes Singlen due to his use of amoral methods for his own gain, whilst Singlen belittles Lux for the former prince's naivete in keeping his dream alive. Nevertheless, though, Lux is respected as a worthy warrior by Singlen.
In Volume 14, both Lux and Singlen had to work together in order to stop the Holy Arcadia Empire from invading Avalon, only for them to turn against each other when Singlen betrayed Lux during their mission.

In Lux's perspective, Balzeride was no different to the Arcadia Empire's corrupted aristocrats mostly because he (Balzeride) viewed women as mere tools. In the fated duel, Lux had a rough battle against Balzeride because of the latter's Divine Drag Ride Aži Dahāka's ability that absorbed Bahamut's ability (Reload On Fire), though the latter ultimately prevailed.
