Castle Swimmer hooks you from the start and doesn’t let go. It’s devastatingly charming with a hint of sweetly heartbreaking.”—Katie Cook, author of Nothing Special

From the moment Kappa tumbles into existence on the ocean floor, his life’s purpose is already decided for him: He is the Beacon, a light to all sea creatures, and destined to fulfill their many prophesies. In high demand and under immense pressure, Kappa quickly realizes that fame and glory are small compensation for a life of predetermined self-sacrifice.

Unable to resist the call of destiny due to a magical yellow cord that appears from his chest and pulls him inexorably to any sea creatures he swims by, Kappa ultimately finds himself drawn to the Shark kingdom, where he is immediately imprisoned. The Sharks’ prophecy states that the curse maiming their people will only be lifted once their prince, Siren, kills the Beacon. But when Prince Siren decides to defy fate and help Kappa escape, Kappa realizes that there might be more to life than fulfilling endless prophesies, leading to a raucous adventure as big and unpredictable as the ocean itself—and a romance that nobody could have predicted.

Episodes 1-19 of Webtoon's Castle Swimmer Season 1 is collected in this stunning graphic novel, which also includes a never-before-seen bonus chapter featuring Kappa and Siren.

Two mermen reject their destinies and embark on a raucous adventure as big and unpredictable as the ocean itself—and a romance that nobody could have predicted—in the stunning second installment of the hit Webtoon series Castle Swimmer.

The sharks want Kappa dead, and time is running out for Prince Siren to save him. Queen Susca knows Siren doesn’t have the courage to kill Kappa, and for the sake of the kingdom, she’s willing to do the deed herself. As tensions run high, neighboring queens pay the sharks a visit to offer an alliance, and while they might just be the means of escape the two mermen have been looking for, it’s unclear if they can be trusted.

Siren will do anything to get Kappa to safety—even if it means never seeing him again, and even if all Kappa wants is to stay by his side. Yet escaping the queen’s spear will take all of Siren and Kappa’s courage and cunning, and there’s no guarantee they’ll both make it out alive.

This beautiful graphic novel collects episodes 20-41 of Webtoon's Castle Swimmer and includes a never-before-seen bonus chapter featuring Kappa and Siren.
