Plot
Ayato Kamina and his classmate Reika Mishima are in middle school and are a young couple, still dealing with some awkwardness. However, the sudden appearance of visitors from an alternate dimension, the "Mu", tears the two apart. All of Tokyo is enveloped in the giant hemispherical Absolute Barrier, which looks very similar to Jupiter, and they become separated into the world inside and the world outside.
Three years later, Ayato, who was left inside, has become a high school student. He has been taught that the world outside has been obliterated and feels as though his memories of Reika are a distant vision. But one day, invaders from outside attack, and Tokyo is engulfed in the fires of war. And as Ayato runs about in confusion, a woman appears before him. The woman says her name is Haruka Shitow and tries to take Ayato outside the Absolute Barrier, saying, "I'll tell you the truth."
