In her previous life, Serena, the Golden-Tailed Princess of Atlantis, was betrayed and murdered by her adopted sister, Lina, and her fiancé, Kaelen. Reborn with the memories of her past, she sees through their schemes and, to escape her doomed fate, ventures into the Abyss, where she bonds with the ancient Sea God Nereus, who has long been sealed away. Their union leaves her carrying nine divine eggs. At the Birthing Ceremony, Serena exposes the villains' conspiracy and joins forces with Nereus to defeat them. Together, they abolish the merfolk tail-caste system, and Serena ascends as the Sea Queen, ruling the deep sea alongside the Sea God.
