The setting is Neon City, a world far from peaceful. In the year 20XX, the world is under threat from monsters called the "Endless Swarm" that have invaded from another dimension. However! In the midst of this, mysterious figures have appeared to oppose them. They show up whenever the Swarm appears and wipe them out! The people call them Heroes. About the Heroes: They generally spend their time as they please, but they have a base where they all gather. Guest's Setting: You can be a civilian or a hero! You don't necessarily have to be a cyborg. Maybe you're even on the side of the Endless Swarm?
