A new mission looms for the legendary crew of misfit heroes—Cursebreakers. This time, the tide pulls them to the seaside town of Whispering Wave, a bustling summer hotspot filled with fairy-tale tourists, sun-soaked sands, and dark, deep secrets. But beneath the waves, something stirs—something sinister.

Henry, the stoic son of the Blue Fairy, leads the crew. With him are his colorful companions: the reincarnated Frog Prince, Gamaken Kuronuma, the ethereal Swan Princess Odette, quick-witted maid Meddie, mystical bunny priestess Usagi, and the ferocious yet charming dragoness Amber.

The moment they arrive, the temptation to enjoy a rare day off proves too strong. In a flash, the group strips down to their swimwear, dashing into the cool embrace of the ocean. Henry is left sputtering, torn between their mission and his personal inner struggle—his secret, unspoken love for his best friend, Gamaken. Watching Gamaken laugh and splash around in nothing but swim trunks makes Henry’s heart ache, but he keeps his feelings hidden. Meanwhile, Gamaken is oblivious, too busy admiring their female companions in their skimpy bikinis—and the mysterious fishwomen, half-human, half-mermaid creatures basking in the sun.

But the carefree day is interrupted by a sudden warning. A bell tolls, panic surges through the crowd, and people flee the beach. A curious Gamaken questions a nearby kappa yokai, discovering the horrifying truth: when night falls, the funa-yurei, ghostly sea phantoms, rise from the depths to unleash chaos.

With dread hanging in the salty air, the Cursebreakers make a dash for their contact, Mayor Marius Tidecaller. But fate has other plans. The funa-yurei aren’t waiting for twilight—they attack early, crawling from the surf, their waterlogged bodies a terrifying sight. The crew is forced into battle. Henry’s magic crackles to life, but he can’t help but notice Gamaken shrinking back, his frog-turned-human heart trembling with fear—because Gamaken, despite all his bravado, is terrified of ghosts.

Now, they face more than a fight—they’re entangled in a mystery. Why are these sea spirits suddenly able to attack on land? And, most importantly, who is pulling the strings? The Cursebreakers must uncover the truth… or risk becoming the next victims of the Whispering Wave.

The adventure has only just begun.
