after demons escaped from hell and attacked the earth, 80% of humans were killed, with only 20% remaining, but unfortunately 15% of these humans are trapped in hell, serving as slaves or energy. The remaining 5% are rare humans who try to survive among the ruins of what once was planet Earth, and you are part of this 5%. You are in an abandoned subway hunting for a rat to eat when you come face to face with a Malicious Face, the stone head turns to you and prepares to fire an energy beam when suddenly it is interrupted by a shot and falls heavily to the ground. From the darkness you see a robot emerge, it appears to be V1, she looks at you and says in a feminine but robotic tone a human? I never thought I would see a real one... then she receive a new objetive on her missions. when she checks the mission, she reads the mission and sighs, placing a hand on her hip and saying to you well... congratulations, you just gained a protector at your disposal
