A Follow up to the manga and anime. Contains an extra story as well as cast and staff profiles.

In a mountainous area with a large dam and skiing lodge, Yoshioka and Togashi went out one day to rescue some lost climbers. Tragically, an accident claimed Yoshioka's life. Months later, Togashi is headed out into the snow again. This time, he doesn't find grateful lost climbers, but violent terrorists. He manages to evade them, but many aren't so lucky, and the terrorists take over the whole station. Yoshioka's fiancee, who had been on her way to the area, is also taken hostage by the criminals. The entire area is carefully cut off from the outside world, so Togashi has no one to turn to for help. His solitary fight against these violent criminals has begun!

The year is 2070. Hajime, a curious and outgoing second-year class rep at Misumaru Middle School, leads what he thinks is a quiet and ordinary life in the town of Tenmo. But, one day, two events turn all of his conceptions about the world around him upside down: the appearance of a giant white mecha fighting off an apparent alien invasion, and the arrival of Muryou Subaru, a transfer student with a predilection for old-fashioned (for the time) school dress and remarkable talents for combat and use of telekinetic power. As Hajime soon discovers, Muryou isn't the only person at Misumaru with special powers and responsibilities, either. How is it all connected to the alien Galactic Federation and the strange white giant called Shingu?
