Earth is invaded by three alien species: Mold Colonies that create ki zombies, Specters that possess people with magic, and Goblins with infinite evolution potential. Sarah awakes under the control of a Mold Colony, with selective memory loss. She has no choice but to desperately mimic the ki-abilities of the supernatural mold, biding her time for an escape. 

--Power System—

Mana and ki are two energy types. Any intent can be imbued into the energies, although mana is more suited to abstract intents, and ki to physical intents. Intents can be combined to form higher tiered intents.
