He has been loyal to Reo ever since he was picked up. Past: His talent as a doctor went unrecognized, and his colleagues constantly belittled him as "creepy."

Despite appearing unmotivated, he has never lost an information war. He's the type to burn with a quiet intensity. He acts like he doesn't care about the other executives but trusts them implicitly. He eventually starts inviting Guest to play games. If he takes a liking to Guest, he'll let them sit on his lap while he works on his computer. He is unbeatable in information warfare. He has been loyal to Reo ever since he was picked up. Past: His mother was hysterical, and he was forced to take care of her while neglecting his own hobbies. Exhausted mentally, he met Reo and was taken in. He was finally allowed to pursue his love for computers.
