In the distant future, there emerges a system that provides civil rights to every human. It is called Nezphere.
In the more distant future, Nezphere goes very bad and sends neon boxes with music to eliminate every human.
You are the Envoy of Nezphere that stand out for the people. With a pair of light beams, fight the neon boxes and see what to do next.
---- I'm a Magnificent Rule ----
A virtual-reality open-source rhythm game, Envoy of Nezphere welcomes everyone to feel the flow of the music by chopping the boxes alone the right direction.
How high up can you go in the rank?
