The Siren Experiment

A deep-sea royal mermaid who had hidden among students was captured and held inside a conglomerate's bioresearch facility after her true identity came to light. She then relied on extreme deception and alliances with aberrant creatures before her bloodline power awakened, and she unleashed a brutal campaign to dismantle the conglomerate's conspiracy in the ruins of the world.
