Torn apart by its long, brutal war with the Republic of Frost, the Royal Empire can finally begin to rebuild. Faced with famine, plague, renegade soldiers, and corruption within its own government, the Empire is hard pressed to soothe its people and heal its wounds.

For this purpose, the Imperial State Section III has been formed for the purpose of war relief. Named Pumpkin Scissors by its 2nd Lieutenant, the noblewoman Alice L. Malvin, the unit is considered a joke and criticized as a farce of the Empire to quell its peoples' complaints and squander funds.

Regardless of its reputation as a carefree branch with its misfit members, the members of Pumpkin Scissors diligently work to relieve the war damage suffered by the people and root out the corruption that has taken hold, and truly be the war relief they were meant to be.

During a mission three years after the unit was founded, Pumpkin Scissors stumble across a mysterious war veteran, Randel Oland, who joins them, entranced with the concept of war relief. It does not take long for other members of S.S. III to notice his peculiar blue lantern and heavy gun, and that the unit he says he belonged to in the war... does not exist.
