Fubuki Sumiye, also known as Fubuki Sumie in Japanese media, stands as a central figure within the Beyblade Burst series narrative. His passion for Beyblade ignited in childhood, sparked by witnessing Shu Kurenai's battles; this early inspiration forged his dedication and instilled a rigorous work ethic from a young age. By age 9 during Beyblade Burst Evolution, he had risen to become Beigoma Academy's strongest Blader, succeeding Valt Aoi as leader of its BeyClub. He later passed this leadership to Toko Aoi when departing for advanced training in America. Physically, Fubuki possesses striking blonde hair and red eyes. His typical attire includes a black shirt featuring the red Beyblade logo, baggy blue trousers, black and blue sneakers, and a light blue pendant around his neck. His personality blends intense calmness with near-obsessive dedication to training, often rendering him oblivious to distractions during practice. He firmly rejects the notion of innate genius, believing true strength comes solely from relentless effort—a philosophy fueling his initial rivalry with naturally gifted bladers like Aiger Akabane. Despite his reserved nature, he shows deep loyalty, notably supporting Aiger through periods of emotional turmoil and corrupted resonance with Turbo Achilles. Fubuki wields the defensive Beyblade Emperor Forneus 0 Yard, specializing in high-speed counter maneuvers. Its documented techniques encompass Emperor Guard (deflecting attacks via its 12-bladed layer), Emperor Drift (drifting on the stadium rim to build momentum), Ultra Emperor Drift (executing trajectory shifts akin to Counter Break), and Emperor Crash (harnessing opponent power for amplified strikes). His launch style integrates Shu Kurenai's Crux Boost methodology, enhancing rotational speed and power. His journey across official media reveals significant evolution. Early in Beyblade Burst Turbo, he clashes with Aiger, initially dismissing him as an amateur before gradually acknowledging his potential through successive battles—a series yielding wins, losses, and draws. Training under Shu in America further refined his strategy, transitioning him toward cooler, analytical battling evident in team engagements with Aiger. Key narrative arcs include his participation in the Luinor Cup Battle Royale against Lui Shirosagi and complex interactions with former ally Suoh Genji, where confrontations exposed underlying tensions over their divergent philosophies on strength and rivalry. Fubuki's relationships define crucial aspects of his path. His foundational mentorship under Shu Kurenai deeply influenced both his technical skills and ideological outlook. His rivalry with Aiger evolved from antagonism to mutual respect, culminating in Aiger later citing Fubuki among the four most influential figures in his early Blading career during Beyblade Burst Surge. Interactions with Suoh Genji reveal layers of past camaraderie and subsequent ideological fractures, highlighted intensely during their emotionally charged semi-final match in the Luinor Cup. Fubuki ages chronologically from 9 in Evolution to 11 during Turbo. His legacy endures through the narrative's thematic emphasis on perseverance, impacting storylines beyond his primary appearances.
