In a world where technology has advanced beyond imagination, crime, and corruption have become the norm. Instead of fighting the problem, the government has become a part of it. The common people were left helpless and afraid until a group of rebels emerged, calling themselves "Code//MK."
Code//MK was a group of former marines and special forces who had decided to take matters into their own hands. They believed that the only way to eradicate crime was by using unconventional methods. Their identities were concealed behind mecha helmets that made them look like robots, and their motto was to fight fire with fire.
