Scientists predicted an imminent meteor impact on Earth that would
annihilate civilization, but contrary to their prediction, the meteor
missed Earth. Though avoiding immediate destruction, humanity found that
the meteor left behind something in its wake, something that would
change the course of civilization forever: a new form of bacteria that
ate through all known metals.
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.
