On planet KOA Z-7, life doesn’t rely on air… it relies on Qi, an energy that keeps you alive and can either transform you… or destroy you. Measured through HUD wristbands, it’s your countdown clock. When it drops below 3%, you shut down. Five Corporations control its flow and weaponize it. Their armies clash for dominance over the Ma-Na Core, fractured after the meteor impact. As the world sinks into despair, a rebel squad known as Ma-Na Kaku rises in the shadows. Each member bears the mark of Qi: some wield it to fight, others pay for it with years of memory. Among them is Aika, a young woman who seems ordinary… until her connection with Qi ties her to forces far older than she imagined. Their journey leads to battles against biomechanical final guardians, colossal beings bonded to their masters through the Core’s energy. Skies crack open with storms of metal and light as armies fight for control. And through it all… a cat is always watching. No one knows why, but where there’s a cat… Qi still flows. Ma-Na Kaku is a realistic, epic, and devastating anime where every choice burns, every power has a cost, and every step might be your last. Would you survive in the MA-NA KAKU universe?
