Spoiler warning....

When Teru awakens he realizes that the shinkansen he is in has crashed and that all his classmates are dead. He remembers returning from a school trip to Kyouto and just before the train entered a tunnel he saw something amazing. He frees himself from the chairs trapping him and finds a lighter in the pocket of his dead teacher, a little later he discovers a flashlight in the conductors cabin.

He finds nothing but dead bodies and when he investigates the tunnel he discovers that the tunnel is blocked on both ends.

Back in the train he finds a radio and from the garbled sound he makes out that the country is in a state of emergency. Suddenly he hears a voice and when he investigates, a semi-conscious girl grabs his ankle. When he finally manages to wrestle her free from the jumble of fallen chairs, somebody picks up his flashlight. It's Nobuo, a boy of the other class. While Teru is glad that he's not alone anymore, Nobou seems disturbed that others are alive too in his personal hell.

They make it to the restaurant wagon where there are food and drinks. The girl, Ako, comes to and Teru manages to light some liquor and create a light. Nobou slowly slips more and more into psychotic behavior.

Thus starts one of the most exciting manga stories of the moment. For the most of the first two volumes the three teenagers are trapped in the tunnel.
What has happened? What was that flash of light Teru saw just before the train entered the tunnel? Why is it getting so hot? Slowly the story unfolds.
Through the volumes we follow Teru and Ako in their desperate struggle to survive in a post-apocalyptic Japan.

The artwork is superb, and the dazzling use of colors in the cover art is sure to catch your eye.
