Last season we had Izetta The Last Witch, which gave us basically WWII, but with a lot of cosmetic influence from WWI.
This season we have Tanya The Evil. People have had a lot fun calling it a show about a Loli Nazi, but really the War we're currently watching is more of a delayed WWI.
But.... a theory I've seen presented in the comments section of the site I've been streaming the Dub on is that basically Tanya will be the Hitler of this alternate history.
Imagine it, this season ends with the Empire being defeated, lots of climatic stuff happens. Then the final after credits scene is a jump several years in the future, an teen Tanya gives a rousing speech to disillusioned veterans. Ad it ends with them raising their hands saying "Hail Tanya".
That would be chilling.
