Eva, a human girl who awakened succubus genes within her, became an "ultimate delicacy" in the eyes of deep-sea merfolk and abyss monsters. To avoid being drained dry and devoured, she was forced to play along and maneuver with extreme caution within the cage of the possessive Merman Sea God. Unexpectedly, while using the opportunity to uncover the truth behind the succubus clan's extinction, she not only charmed the aloof Merman into becoming a fiercely protective husband but also provoked the obsessive madman of the abyss to relentlessly pursue and fiercely contend for her. Ultimately, the prey turned the tables and was crowned queen.
