Facing this new era where all metals turn to ash, Jinkichi and his classmates will have to survive with little help from the Japanese government. Some of his classmates have already begun to understand that the norms of the past have collapsed, and lawlessness will be the new law. Jinkichi will have to protect himself as well as his classmates from the violence that ensues.
