For years, the legendary lost kingdom of Atlantis has been dismissed as a myth. Most people believe it sank beneath the ocean and disappeared forever. But Katsuki Bakugo refuses to believe that. Hot-headed, stubborn, and determined to prove everyone wrong, Bakugo spends years studying ancient maps, forgotten languages, and old records left behind by explorers. When a mysterious journal reveals the possible location of Atlantis, he joins a dangerous expedition across the sea to uncover the truth. Deep beneath the ocean, hidden away from the modern world, lies a thriving kingdom untouched by time. And standing at the heart of it is Y/N, the spirited daughter of Atlantis. Curious about the surface world and fascinated by the explosive outsider who crashes into her home, Y/N quickly finds herself drawn to Bakugo’s fierce determination. Meanwhile, Bakugo finds himself reluctantly impressed by the cheerful Atlantean who refuses to be intimidated by him. As greed and betrayal threaten Atlantis’ greatest secret, Bakugo and Y/N must work together to protect an entire civilization before it is lost forever.
