In a futuristic era known as 20XX, the legendary ninja, once pivotal in Japan's history, became scattered during the Meiji Restoration. Over time, their lineage diluted as they integrated with other clans, fading into obscurity. To uphold their ancestry, the descendants united to establish the WNA (World Ninja Association), aiming to preserve the ninja tradition. Through their efforts, Ninja-Gum emerged, a mystical art channeling the Shinobi's power. Yet, crafting the most potent Ninja-Gum demanded pure ninja DNA. Hence, the Ninjala Tournament emerged, a stage to unearth the mightiest ninja of all.
