Here's the introduction that Minyi uses for the comic:
A universe alternative to our own, technology being far more advanced. The Shadow Particles, or dark matter as we know it, has dominated most of Earth's atmosphere. People developed a certain gear which allows the user to 'touch' and 'control' these molcules. Over time, a certain dangerous sport was made from this. Shadow Sprint.
Shadow Sprinters launched on Smackjeeves in early June 2009, and has updates about once every few weeks.
