After My Sister Pushed Me Into the Sea,I Awakened as a Mermaid

My sister pushed me into the radioactive ocean to die.I woke up as a Mermaid Queen with the power to control minds and clean the ocean.Monsters became my pets, and I sucked the poison right out of the world.I led my army to crush my ex and my sister on their "fancy ark."But I found out the apocalypse was just an alien setup.The real war for Earth has just begun.
