Evelyn, a girl suffering from severe school bullying and labeled a powerless Rank‑Zero outcast, awakens her sealed SSS‑Rank Sea‑God bloodline on the brink of death. As her ancestral relic *Tears of the Sea God* breaks the shackles, she learns she is a descendant of the Sea God, and her mother was poisoned to death by the shadowy Tide‑Eater Cult.
Shedding her inferior, bulky outer shell, Evelyn conceals her true power and returns to the academy as an A‑Rank water mage. On the academy trial grounds, she strikes back hard at those who once tormented her. Meanwhile, she teams up with night‑watch knight Kyle to uncover the truth behind her mother’s murder.
As clues unfold layer by layer, the seemingly amiable headmaster reveals his true villainous identity. When the long‑buried deep‑sea power fully awakens, she wields the authority over the oceans and declares war on the conspiratorial cult. Yet the real mastermind behind everything still lurks in the shadows. Her path of vengeance is far from over, and the Sea‑God daughter’s battle has only just begun.
