Dragon Head

Teru (Satoshi Tsumabuki, Sabu) wakes up after his train crashed in a tunnel. He finds himself surrounded by his dead classmates, and the tunnel has completely collapsed. He soon realizes he is not completely alone. Two other students have also survived the crash. Nobuo (Takayuki Yamada) has gone completely insane in the crash, sick of being bullied for so long by his classmates. Ako (Sayaka) is unsure who to trust, but mostly just wants to escape Nobuo's violent revenge.

Although Teru and Ako believe that they will be rescued if they just wait long enough, Nobuo belives he saw a strange red flash just before the train crashed. He is convinced that the world is destroyed, that they are the only three that have survived. After a fight, Teru and Ako escape from the collapsed tunnel through a tube that leads into the world above, although neither of them know what to expect once they reach the surface.
