Haiku wakes up in a post-apocalyptic world where humans no longer exist. After the extinction of the human race, machines were the only intelligent beings left to inhabit the planet.
Four artificial intelligent beings soon evolved and developed a world of order and stability. Programs and machines lived in peace for many years, until the virus spread.
It corrupted the programs first, then after, the machines. The machines could not function without the correct programs and so the world began to break down.
It's up to Haiku to restore order!
