Playing a virtual reality game your Japanese parents created might be fun for some, but not for Haru Motoyo. See, Haru is quiet, reserved, and generally a shy kid. His twin sister Millie is distinctly different, with a peppy attitude and always up for an adventure. What will happen when the two of them play The Game of Tengoku together? And most importantly, what happens when an immoral engineer from the video game company threatens to trap the twins inside the simulation of reality forever?
The adventure is waiting.. are you ready to take on The Game of Tengoku?
