This is a parody of The Great Dictator, Charlie Chaplin's first talkie.

who is this girl? i’ve seen various pictures of this nazi anime girl with a very specific hairband (i’v provided another pic of her below) but i can’t for the life of me find who she is. this post does say it’s this Yukino girl but i’ve looked her up and can’t find any other art of her that uses this design.
