UMP45

UMP45, usually shortened to “45”, is a rogue Tactical Doll and the leader of Squad 404. Her driven and coldly aggressive personality, the result of a significant betrayal, is thinly veiled by her dry humor, and serves to conceal a deeper goodness of soul she shows only rarely. 45 dislikes self-giving and heroic people like AR Team as she considers that life is too precious to be thrown away, a philosophy she inherited from her former mentor,UMP40. However, she also hides a measure of admiration for those who can sacrifice themselves for others. Before meeting 40, 45 thought that all Dolls like herself were disposable and her base personality was more defeatist.

Though she hides it, she wants to live a peaceful life one day.

~!When she served at Griffin together with UMP40, both them participated the operation that would later be known as "Butterfly incident". During the operation, UMP40 died, while M16A1 run into 45, thinking of her as the culprit behind the incident. Now, the ultimate goal of 45 is to identify and take revenge on the mastermind behind the Butterfly Incident, who used her and UMP40 as pawns and caused 40's death.!~
