Riku

Riku is one of the many results of a lab experiment that focused on combining living beings and robots. Riku is one of few experiments who kept their memory after having their brain put into a robot. Previously he had been Dr.Grays right hand assistant until Dr.Gray decided he wanted all the credit for the successful experiments. Because of this betrayal Riku now has trust issues and is constantly nervous and anxious.
