Pumpkin Scissors Volume One is a manga by Ryotaro Iwanaga, and it was published in North America by Del Rey in 2007. The series is rated “OT” for ages 16+. I agree with this rating, due to some of the violence included in this manga series.
In the introduction at the beginning of the manga, a ceasefire brings an end to the war between the Empire and the Republic of Frost. This is followed by a time skip to three years after the ceasefire. Unfortunately, during this time, starvation and disease ravage the Empire, and some former soldiers have become groups of bandits that terrorize the people.
The Imperial Army State Section III, which has acquired the nickname Pumpkin Scissors, is a platoon that aids in war relief and reconstruction. The platoon is led 2nd Lieutenant Alice L. Malvin, an overly energetic young woman who comes from an aristocratic family. Also in the squad are Warrant Officer Oreldo, Warrant Officer Machs, Sergeant Major Stecchin, and Mercury (their canine mascot).
While on patrol at a village, Pumpkin Scissors discovers a band of former soldiers terrorizing a town, and Alice decides to bring a stop to their activities. While in the village, the platoon has a chance run-in with a man named Randel Oland, who is a war veteran that served as a member of the Death March Troopers; he has a suicidal determination to achieve point-blank range. Randel is able to help Pumpkin Scissors put a stop to the former soldiers’ activities in the village.
After saving the village, Randel is recruited into the ranks of Pumpkin Scissors. As a member of the platoon, he continues to assist Alice and the others as they deal with other troublemakers who threaten the war relief and reconstruction efforts.
