Description
Elle Ragu holds the title of the 59th Sevaar of the warrior kingdom of Kurda, a rank she achieved at the age of fourteen, which is three years before the main events of the story. She is known by the fighting epithet Shadow Skill, which is also the name of her signature martial arts style.

Elle was orphaned as a child when her parents died from a rampant disease. She contracted the same illness, and her older brother, Diaz Ragu, embarked on numerous dangerous missions as a mercenary to fund the medicine that saved her life. While Elle survived, the toll on Diaz's body was irreversible, weakening him to the point where he had to abandon his own aspirations of becoming a warrior. He instead became a blacksmith, forging weapons such as his Black Wing boomerangs. Elle carries a profound and persistent sense of guilt over this, believing that her brother was more deserving of the Sevaar title than she is.

In terms of personality, Elle is known for her impulsiveness, a tendency to start brawls, and her heavy drinking. These habits result in immense property damage and keep her in a perpetual state of financial debt, with any money she earns quickly going towards paying off damages or bar tabs. While she is not particularly intellectual in general matters, she is a genius in combat. Her fierce confidence often manifests as a declaration that her kicks are invincible, though this ego can be a tactical vulnerability. This is balanced by an unwavering loyalty to her adopted family and a determined drive to protect the stability of Kurda.

Elle's primary motivation as a martial artist is to repay her brother for the sacrifices he made for her, with a sense that her achievements and strength are a way for her brother to live through her. Early in the story, she rescues a young boy named Gau Ban from bandits who slaughtered his village. Although Gau initially intended to steal from her and learn her techniques, they eventually formed a genuine sibling bond, with Elle becoming his mentor and guardian. She trains him in the martial arts with the goal of making him a candidate for the rank of Sevaar.

Her most significant relationship begins as a rivalry with Fia Arcana, later known as Faulink Maya. Fia believed Elle had murdered her father, a master of the Sui Rem talisman arts, and sought vengeance using forbidden talismans. After a confrontation in a collapsing mine, Elle saved Fia's life, prompting Fia to question the truth of her father's death. It was later discovered that another disciple, Louie Francil, was the true killer. This event transformed their enmity into a deep, sister-like friendship, with Fia often acting as Elle's moral compass and the brains to her brawn. Another close ally is Kyuo Liu, a Septia demon-beast hunter whom Elle and Gau help to defeat the King of the Moon. Kyuo's expertise in setting traps proves invaluable, and she joins their group, later becoming a moral support for Gau.

Throughout her journey, Elle participates in arena battles, thwarts assassination attempts from other ambitious warriors, and mediates conflicts between Kurda and neighboring nations. Her role involves balancing her duties as a Sevaar against the legacy of her brother Diaz, who sometimes intervenes to help her against powerful entities like Darkness. Her development is intertwined with mentoring Gau Ban; as he grows and emerges as a formidable warrior, she must reconcile her role as both a fighter and a guardian.

As a fighter, Elle's abilities are superhuman. Her martial art is the Kuruda Ryu Kosappo, a discipline that emphasizes kicks and footwork. This style is categorized under Eigi (Shadow Skills), which stands in contrast to Hyogi (Open Skills) that focus on punches and throws. Her signature techniques include Sword, a flaming ki-enveloped kick; Dagger, a vertical front kick; Chainsaw, high-speed revolving kicks; Boomerang, a neck-grappling spin kick; and Blade, an aura-enhanced roundhouse kick. She can employ energy-based defenses like Shield and counter mental intrusion with a technique called Kabuto. As a Sevaar, she also has access to powerful techniques like Cannon, a disintegrating energy blast, and Kamui, hyper-acceleration that erases her presence. Her physical capabilities include city-level destructive power, massively hypersonic speed, extreme endurance, the ability to create solid afterimages, and regeneration through a technique known as Zenryoku Kaiten.
