Майн

Mine is a self-proclaimed "Genius Sniper", as well as being a sharp-tongued and quick-witted member of the assassin's group, Night Raid. She is often quick to anger, and easily irritated with those she does not know well. Despite this cold exterior, she has shown to be warm and kind to those she has opened up to. Mine wields a powerful Teigu in the form of a rifle called the "Roman Artillery: Pumpkin" that fires highly concentrated piercing shots of spirit energy. Her proficiency in its use allows her to strike any target with extreme precision. When Pumpkin's user is in a dangerous situation, the power of its shots is​ magnified.

Manga spoilers: Tatsumi and Mine retired from service and settled down away from civilization where they married and had a child.
