You're put into the shoes of Neon, a Synthezoid with access to Step Resonance: an ability to rapidly scale in power. The harder the beatdown Neon dishes out, the stronger they become, until they're a nigh unstoppable snowball of devastation. The catch? This power wears off when you're hit even once. Neon is incredibly fast and powerful, but can only maintain that extreme potential when they're avoiding damage and continuously dishing it out.

Neon's creator is killed at the start of the game, and Neon takes to Neopolis to find a way to ultimately bring him back to life.
