Every battle in GKOI is a clash of skill, reflex, and spirit. Step in as a Traveller and fight through 1-on-1 duels in dynamic Arenas inspired by the Path of the Koi — from magical cities to ancient temples where light and shadow collide.

Win matches to earn $GCoins, unlock loot-box Shields that boost your combat stats, and collect Powers and Battlecards to unleash devastating combos, elemental finishers, and seasonal rewards.

As your mastery grows, your Spirit Koi evolves — granting new elemental strikes, healing surges, and energy bursts that can turn a fight in seconds. To advance through the story, defeat the Five Guardians, each testing 5 different Virtues.

Only those who conquer all five can face Lady Kurayami and her Lava Dragons in the final showdown. Defeat her to challenge Empress Amaryū herself — and unlock the ultimate transformation into a Golden Dragon, the pinnacle of power in the GKOI Arena.

Fight. Evolve. Ascend. The legend is yours to forge.
