11 partes Continúa In a world submerged beneath endless oceans, humanity has adapted to survive. Cities of glass and steel hover above the water, while others thrive deep beneath the waves. Evolution gifted humans extraordinary powers to navigate this new reality: some command water, others harness bioluminescent energy, and a rare few possess abilities tied to the senses.
Fifteen-year-old Kai is an orphan who lives in the sunken slums of Aquarion, scraping by on odd jobs and scavenging in the ruins of the old world. His unique power is both a gift and a curse-his hearing is so sharp he can detect whispers from miles away, even hear the faint hum of ocean currents. But Kai has a secret: he cannot speak. His voice was lost in a traumatic event he barely remembers, leaving him isolated and misunderstood.
When the annual Aqua Trials are announced-a grueling competition held in the floating city of Zenith with a prize of 50 billion gold-Kai sees his chance to escape poverty and start a new life. The Trials are open to all, but they are perilous, designed to test the limits of human ability. For Kai, the stakes couldn't be higher.
