Myther

It is the near future, and the night sky over Tokyo glitters with LED light. One of the screens, five stories high, shows a woman tucking a device behind her ear. A voice makes a promise. “Want to become a new you? Meet MYTHER—the device that will design your perfect self and make all your dreams come true.”

Meanwhile, inside one of these buildings, someone is committing a savage and inexplicable murder.

The shining land of Japan is full of beautiful people, thanks some would say to Ideva, the company that developed the Myther. Representing the forefront of AI technology, this curved piece of metal contains a custom-built neural interface designed to help you become the ideal version of yourself, and eliminate the weaknesses that are holding you back. But it’s become clear that something is going wrong, and Kyo, an agent with the top-secret National Special Intelligence Office, has been assigned to unravel a series of bloody deaths that all seem to revolve around the device that has changed his world. Yet how can anyone protect the public when all the powers that be want to do is cover it up, and everyone’s loyalty is in question…?
