My Little Sister Is Actually Cthulhu

Evil-god cultists, potions, kindred, mutants, dinosaurs, starships, divine seeds.

Dark nothingness pants and heaves, the so-called gods feast ravenously, and their followers pray with devout fervor.

As seven stars align and five Earths hang in the familiar sky, people suddenly discover that the end of the potion system is slavery to the gods.

Will people choose to become slaves to these so-called gods? Take up technology and fight back? Embark on their own path of evolution? Or inherit the legacy of the divine race that perished protecting this world?

"Big brother, you're his incarnation. Which side are you going to take?"

Looking at the unnameable monsters surrounding his sister, the human champions on the other side, and the enormous starship in the sky, Su Ye declares, "I am myself, not his incarnation. Draw your sword, my sister. Today, I fight for humanity!"
