Description
Fuuko Kurasaki, known in the Accelerated World as Sky Raker, is a Burst Linker who was born with a hereditary genetic defect that resulted in the absence of her legs from just above the knees. Her parents chose to allow her birth despite this condition, a decision she quietly resented while growing up. From infancy, a Neurolinker was used to monitor her health, and she later received biocompatible prosthetic legs, which she typically conceals beneath high knee-socks to protect the artificial flesh.

Her personality is complex, blending refined politeness with a hidden, almost sadistic inclination to tease her friends and push them into challenging or dangerous situations for their own growth. She is known to smile while tying rival Burst Linkers to high places or dropping allies into the middle of enemy formations. Despite her willingness to help others without expecting anything in return, her eyes often carry a hidden sadness, reflecting her lingering regret over her prolonged separation from her closest friend, Kuroyukihime. This sadness is balanced by a deep, if occasionally obsessive, affection for her younger comrade Utai Shinomiya, the Ardor Maiden. In the real world, Fuuko is a gorgeous young woman whose beauty rivals that of Kuroyukihime, possessing long, flowy light brown hair and a tall, curvy figure.

Fuuko’s primary motivation in the Accelerated World is the pursuit of true flight. This desire originated in her childhood when she read a science fiction novel about children genetically engineered to live in a weightless environment. Subconsciously, she longed to visit such a world, and this wish manifested as her Duel Avatar, Sky Raker. For years, she was known as "the person closest to the sky," using her Enhanced Armament, the Gale Thruster jet pack, to achieve extraordinary jumps and short-distance flights. Her obsession with attaining true flight drove her to a drastic act: she repeatedly begged her friend Black Lotus to permanently cut off her avatar's legs to reduce its weight and increase her will to fly, a request that was ultimately granted.

In the story, Sky Raker serves as a crucial mentor to the protagonist, Haruyuki Arita and his avatar, Silver Crow. After the villainous Dusk Taker steals Silver Crow's wings, Ash Roller brings Haruyuki to Sky Raker at her isolated home atop the virtual Tokyo Tower. She refuses to restore his wings, explaining that such loss is permanent, but reveals she can teach him a power called the Incarnate System, which allows a Burst Linker to materialize their willpower. Her training method is characteristically harsh but effective, involving throwing Silver Crow off Tokyo Tower and forcing him to use Incarnate to climb back up. This role connects to her past as a founding member and the deputy leader of the original Nega Nebulus legion, where she was known as the Air Element of the group's elite "Four Elements." In battle, she was a formidable strategist, earning nicknames like "Astro" and "ICBM" for her terrifying tactics, which included dropping Ardor Maiden onto enemy strongholds from great heights.

Her key relationships define much of her character arc. Her bond with Kuroyukihime, the Black King, is her most significant. They were inseparable friends and comrades until Fuuko's obsession and her request to have her legs severed created a rift between them. This was compounded by the failure of an assault on the Imperial Palace and the subsequent disbanding of Nega Nebulus, after which she retreated into a self-imposed retirement in the Unlimited Neutral Field, losing contact with her old friends. She also maintains a unique rivalry with Blood Leopard from the Prominence legion and a mentor-like relationship with Rin Kusakabe, the Burst Linker behind Ash Roller, whom she considers her "child" in the Accelerated World.

Fuuko experiences significant development throughout the narrative. Her reunion with a reformed Nega Nebulus, facilitated by Haruyuki and her student Ash Roller, begins to heal the old wounds. A major breakthrough occurs during the Hermes Cord Vertical Race. Silver Crow correctly deduces that her avatar was never meant for short atmospheric flights but for combat in the weightlessness of space, representing her deepest childhood wish. Upon this realization, her avatar's legs spontaneously regenerate, resolving her lifelong psychological block and fulfilling her true desire. With this growth, she fully rejoins the legion and rekindles her friendship with Kuroyukihime, becoming an active and powerful member of the reborn Nega Nebulus.

Notable abilities include her mastery of the Incarnate System, a power she understands more profoundly than almost any other Burst Linker. She uses it not only for attacks but also to propel her ornate wheelchair. Her signature ability, prior to her legs' regeneration, was the Gale Thruster, a jet pack-type Enhanced Armament that allowed her to launch herself incredible distances, reaching heights of up to 350 meters, a feat that earned her legendary status before the advent of true flight. After regaining her legs, she is able to combine her existing power with her newfound purpose, becoming an even more formidable force.
