Elisa, a flightless fire fairy, spends the majority of her time alone working as a swordsmith, vastly underpaid and living only to survive. She believes the rest of her eternal existence will be full of boredom in a village she hates. Until one day, a group of wanted pirates destroys the forge, demanding the necklace that she bought off a trader years ago. Elisa refuses to hand over her possession to a group of criminals, and she's dragged onto the deck of The Violet Skull. As the Captain of the most infamous ship on the high seas, Flyn Barun has hunted treasures since he was a boy. He's carved out a name for himself in a world determined to destroy him. However, one wrong move sends his entire life spiraling, and he's suddenly no longer the master of his fate. Flyn desperately needs Elisa's necklace to unlock a centuries-old treasure. If he doesn't complete this hunt, the lives of his crew, and possibly more, are on the line. He has no choice but to bring Elisa with him. Elisa despises Flyn, but she quickly realizes there's more to this treasure hunt than he's letting on. And regardless of the animosity between the two, they make quite the team. While battling other pirates, sirens, and witches, a villain with ties to the treasure threatens the peace of the realm. Elisa and Flyn are forced to make sacrifices that push them closer together. But will it be enough to secure their survival, or will they join the fallen sailors at the bottom of the ocean?
