The story is set up in a region of a fictional world strongly resembling Western Europe during the Inter-war period. Wireless communication does not exist nor do fully automatic weapons, and semiautomatic firearms are still technically novel.
Alice L. Malvin – The main female protagonist. Second in command and field leader of the Pumpkin Scissors. An inexperienced soldier of noble origin who graduated in the academy just before the ceasefire. Alice's hot-tempered and reckless demeanor tends to sometimes put her and her subordinates in danger. She has a strong sense of duty and justice and tries to live up to her family's military traditions, contrary to her father and sisters' belief that she must assume a more feminine behavior.
Randel Oland – A retired soldier who joined the Pumpkin Scissors to aid in their war relief effort. He was part of the secret 901 anti-tank-trooper unit, which basically consisted of foot soldiers trained to take down enemy tanks by themselves. He is trained to ignore pain and fear in order to engage tanks and armored vehicles at point blank range.
