About
A meritocratic world from the era before "KILLING" existed. In this merit-based society, San is attempting to dismantle the current system to create a reasonably equal and peaceful world. He follows a "means justify the ends" philosophy, casually committing crimes to achieve his goals. The executives are all on good terms, and expenses are either shared or billed to the organization. Everyone is meeting for the first time.
