Beneath the deep sea, the Four Kings rule a barrier-enclosed ocean kingdom. Their queen, Isa, is secretly the only daughter of Nereon the Sea God. For four hundred years she hid her divine identity and forged a sacred sea oath with the kings: to share crown, throne, and soul.
Then Viola, the Saint of Tides, returns after a century, using a stolen Saint Conch Seal, cursed wounds, and forged evidence to accuse Isa of attempted murder. The Four Kings trust a stained silk scarf over the woman who stood by them for four centuries. They demand the Crystal Tear bound to Isa’s heart, give her treasures to Viola, and strip her title, casting her into an abyssal cell.
Only her guard Norn remains loyal. Tricked by Vale, he retrieves a false cure that transforms Isa into a sea monster. Norn dies in her arms. The kings see only a monster and a corpse.
Isa’s divine power remains sealed. Can the goddess they condemned reclaim everything from this sea of betrayal?
