(Since I like Millie so much I decided to make the past version of her)

Mildred Knolastname[12][13] (née Haymurder[1]), more commonly known as Millie, is an assassin at I.M.P, Moxxie's wife, and one of the main protagonists of Helluva Boss.

She is the exciteful powerhouse of the I.M.P gang who always fights alongside Moxxie.
Tho, this is Millie from past so she doesn't know Moxxie, Blitzø and Loona yet
