Yoshio is thirty years old, and his life is a mess. A shut-in living with his parents, he has no job, no relationship, and no prospects. When he receives a new sim computer game that boasts characters created with a new kind of A.I., he doesn't think much of it-until he gets drawn into a fantasy world so vibrant and lifelike that its residents can't just be game characters. Suddenly finding himself the benevolent god of a scrappy fantasy village is a lot for Yoshio to handle, but it might be the key to the change he desperately needs.
