Tetsuya Kurodake channels his boundless energy into the Magic World as a Buddyfighter whose infectious enthusiasm mirrors his unshakable bond with the Demon Lord Asmodai. A carefree novice evolves into a resilient competitor, his growth marked by edible bananas sprouting endlessly from his hat and a vibrant green-and-yellow jacket capped with orange buttons that shift expressions with his emotions. Early struggles reveal tactical gaps in his deck-building, costing him matches against rivals like Gao Mikado and Rouga Aragami until mentor Baku Omori refines his strategy, unlocking victories over Noboru Kodo and Sofia Sakharov. The Gaen Cup finals test his resolve when Sofia’s mind games push him to the brink, but Asmodai’s cunning interventions reignite their trust, cementing his rise from underdog to contender. Emotional fragility surfaces when confronting Terumi Kuchinawa’s memory-altering powers, triggering a raw breakdown mid-duel, yet he persistently initiates rematches to strengthen bonds over rivalry. Asmodai’s guidance blends mentorship with mischief, teaching through riddles and pranks while their camaraderie deepens. Later, as a Buddy Police recruit, he clashes with Hundred Demons operatives and Yamigedo’s threats, his mixed results underscoring enduring challenges. His deck evolves into the 72 Pillars archetype, synergizing with demons who mirror his flair for dance and theatrics. Combat becomes a stage for rap verses, breakdancing strikes, and humor to lighten tensions, even as setbacks against Gao or Zanya Kisaragi test his resilience. Internal conflicts emerge when loyalty to friends clashes with ambition, driving reckless decisions to confront impossible odds in tournaments, aiming to inspire allies. While joy and friendship remain core, strategic refinement and emotional growth gradually align these ideals with competitive triumphs. Relationships with Terumi and Asmodai weave threads of redemption and trust, while cross-world crises like the Omni Lords’ schemes expand his role as a linchpin in Buddyfight’s ever-shifting battles.
