"crime is the only way now"

It is now the year 2225 and the Earth has turned more sophisticated than ever. The law systems, technology, and even the civilians have changed drastically from the past. Criminals are now being sent to space station countries known as Isles and given the duty of defending the world from extraterrestrial invasions. No one wants to be "Sent" except Mercy. Mercy Hahn is the most wanted criminal in the world, setting a record of a total 178 crimes and murders. The only thing she ever wanted was being sent to the Isles, and her wish comes true and with it, she drags a young man named Ryker into her problems. Maybe they're just little nuts.
