The Shadow Skill manga and anime series has a varied cast of characters originally created by Megumu Okada.
Elle was saved, but Diaz' body was severely weakened by his ordeal, to the point that he had to give up on being a warrior, instead devoting himself to crafting his Black Wing boomerangs.
With his dedication and signs of promise, he quickly catches the attention of the 57th Sevaar, Scarface, who decides to help Gau improve, albeit only indirectly.
Voiced by: Akio Matsuoka (Japanese); Greg Ayres (English) Fia Arcana (フィアー・アルカナ, Fiā Arukana), also known as Faulee (フォウリィー, Fourii) and later takes the title Faulink Meijer the Plasmatizer (ブラズマタイザー・フォウリンクマイヤー, Purazumataizā Fourinku Maiyā), is the daughter of a famed Sui Rem, a sorcerer who uses magical talismans in battle, who was also a master of Shadow Skills.
Gau overhears this and fights and defeats Louie, blasting him off the cliff where they stood overlooking Elle and Faury, consequently aborting their own battle.
In the manga, it was emphasized that Faury was a bad cook, and was also revealed later in the series (after the point where the anime ends) that she was also married.
Kyuo returned to Kurda and tried to hire a group of thugs to help her hunt down the King of the Moon, but they had other things in mind (a young defenseless girl alone in a bar, you get the idea).
It startled everyone, therefore, when Kyuo admitted that she wanted it dead, not captured – a desire counter to the purpose Septias played in society.
During the hunt, Kyuo showed a remarkable talent for setting traps, as well as handling a series of chakram-like rings called chulinks.
These rings are an integral part of a Septia's abilities and duties, serving as focal points to activate and control their traps.
It was Kyuo's efforts in the end that saved them, her traps pinning the demon-beast in place until the sun rose, and the King of the Moon's powers waned to the point where it could be, and was, killed.
It was also revealed that Kyuo possessed horrific scars on both arms from the early days of her training, a result of mishandling her chulinks.
Later on, she met Lohengrin, a Vaar who specialized in Open Skills, who fell madly in love with her but whose affections she did not seem to notice.
He fought side-by-side with Kai Shinks and Vy Low, the 56th and 57th Sevaars Crimson and Scarface, eventually becoming close friends with both.
He succeeded and was able to save Elle's life, but as a result of the extra battles that he fought in, his body was greatly weakened and had to give up his dreams of becoming a Sevaar.
Diaz won the battle ultimately, but he also died moments later, his body finally succumbing to the ravages of his injuries.
Shortly after his death, he was bestowed the title of "The Sword of Ashlianna" by Princess Lilivelt Lu Biju, the highest honor ever granted.
Though Diaz had indeed earned this title, its bestowment was politically motivated as well: because of Shere Kahn and Ren Fuuma's machinations, war was threatening to break out between Kurda and the other cities.
By granting the title of "The Sword of Ashlianna" to a Kurdan citizen, that war was immediately averted, as no one desired to go against the Holy City's decree.
Later on, however, it was revealed that on Diaz' death, his soul had been deliberately sealed by Darkness into his Black Eye until such time as Kai Shinks could restore his body.
During Gau's battle with Ren Fuuma, the efforts of Kai, Darkness, and Lunaris Umbra finally bore fruit.
That is the last we see of Diaz until a mysterious dialogue between Darkness and Lunaris about someone who suddenly disappeared because his mission was over, to bring courage to a boy.
Voiced by: Mitsuru Miyamoto (Japanese); Jason Douglas (English) Vy Low (ヴァイ・ロー, Vai Rō), the 57th Sevaar known as Scarface, is the most powerful warrior in the history of Kurda.
Receiving the title of High-Sevaar at the age of 16 when he defeated King Eva Stroll, the 55th Sevaar Hawk Eyes, in combat, he became the heir to the throne and a role model for the new generation of Vaar to follow.
Like all Sevaar, he tends to put up an aloof air whenever he is in public, not even glancing at his own wife, Folstise, the Ordo Codex of Juliannes.
Voiced by: Yasunori Matsumoto (Japanese); John Swasey (English) Scribe Lohengrin (スクリーブ・ローエングリン, Sukurību Rōengurin), or "The White Lightning", is seen in minor roles in Shadow Skill parts 1 and 2.
He wears big, red, cherry-like earrings which play a role in Gau's most crucial fight at the end of the series.
Despite being the closest associate of his successor Scarface, he was responsible for giving him his famous scar when they fought in a duel before Vy Low became the 57th Sevaar.
He is of Screb Lohengrin and guardian of his grand-niece Kyuo Liu, whom he took under his wing after her grandfather was killed when the monster known as the Moon King massacred the rest of their group of demon-beast-hunters.
Voiced by: Yuri Amano (Japanese); Monica Rial (English) Glad Di is the Commander of the Juliannes Imperial Guard.
