Republic of San Magnolia.
Every day, it was invaded by the unmanned weapon <Legion> of the neighboring empire.
However, in response to the attack, the Republic side also succeeded in developing the same type of weapon and rejected the threat with barely any sacrifice.
Yes-ostensibly.

The truth is that no one was dead.
Outside all 85 parcels of the Republic. <The 86th ward that does not exist>.
There, boys and girls branded as <Eighty Six> continued to fight as <manned unmanned aircraft> day and night.
A young boy, Singh, who leads young people to the dead, and Rena, a girl who became < command controllers (handlers) who take command of them from far >in special communications.
The story of a fierce and sad battle between the two and a farewell begins!
