"Omega is a hostile organization designed to train artificial humans to dominate and rule the entire world. With the help of androids and terrifying weapons, they have destroyed many people and cities. The police and military could not cope with the power of Omega's cybernetically enhanced humans and many innocent people were destroyed. Only the warrior girls Isfer, Shizuku and Natsumi can save the world, as they possess incredible strength that is comparable to that of artificial humans. However, the Omega ranks have long been hatching a plan to enslave the girls, which involves reprogramming their combat attire, brainwashing them, and turning them into the last sluts of sex slaves.
