Castle Swimmer: Volume 3

After leaving Siren to recover from his wounds in the shark castle, Kappa finds himself out in the big wide ocean once more. Minutes into his newfound freedom, another prophecy intervenes, pulling him towards a giant demigod crab scuttling along the ocean floor. As Kappa tries to figure out why he is drawn towards this crab, he comes across three magic-wielding octopi with a tragic past and uncovers more about his greater purpose as the Beacon.

When Siren finally leaves the shark castle a month later, Kappa is long gone. Alone in the greater ocean that he's only ever heard about, Siren quickly finds that he's unequipped to fend for himself. After having his supplies stolen by some thieves, he luckily finds himself in the company of a young fish and his mother and joins them on their travels. As they teach Siren to fight and tough it out in the wild, he begins searching for a cure to his curse.
