The portal to the Duel Spirit realm shimmered like liquid glass as Kaito and his friends stepped through. The air was thick with energy, charged with the raw power of countless battles fought across time. The landscape was a swirling tempest of colors—spirits, cards, and memories blending into a vast arena beyond reality.
"This is the birthplace of dueling itself," Jaden said, eyes wide with awe. "Where all began."
Kaito felt the weight of destiny pressing down on him. The First Duelist's challenge was clear: he must prove himself not just as a duelist, but as a guardian of the very essence of the game.
From the swirling mist emerged a figure cloaked in flame—an ancient spirit that radiated a fierce, almost primordial power. "I am Ignis, the First Flame," it declared, voice echoing like thunder. "To claim your legacy, you must face me in a duel that will test your spirit and your heart."
The Duel Disk on Kaito's arm ignited with blue flames. "I'm ready."
Ignis's deck was unlike any Kaito had encountered—cards that burned with searing energy, monsters forged in the fires of creation, and spells that altered the battlefield itself.
The duel began with a fiery blast as Ignis summoned Flame Sovereign – Pyraxis, a colossal dragon wreathed in fire and ancient magic. Kaito responded swiftly, calling forth Blue-Eyes White Dragon, its icy blue scales shimmering in stark contrast.
Each turn was a test of wits and will. Ignis's flames licked at the edges of Kaito's defenses, threatening to consume him. But Kaito's bond with his deck—and with his friends—kept the cold fire of determination burning bright.
"Azure Monarch Dragon, Valtherion! It's time!" Kaito shouted, fusing his dragons into a majestic being of ice and flame. The clash of powers sent shockwaves through the spirit realm.
The final moments were a blur—a fierce exchange of attacks, spell counters, and heart-pounding decisions. When the dust settled, Kaito's Neo Blue-Eyes Ultimate Sovereign stood victorious, the flames of Ignis's deck extinguished.
Ignis bowed his head in respect. "You have earned the right to carry the First Flame's legacy. Protect the spirit of dueling, Kaito."
As the arena faded, Kaito knew this was more than a victory—it was a promise. The legacy of the Blue-Eyes was alive, and so was the future of Duel Academy.
