Some really strange ideas I have about what things (themes, characters, entire series) relate to what non-anime things and some arguments on why or what I really mean. I'm really going for non-obvious and wacky stuff, so there might be some reaching. But it's amusing -- to me.

I think...	Is related to...
Tanya von Degurechaff from the Saga of Tanya the Evil	Friedrich Nietzche's Übermensch because of their (he who reincarnated as she) denial of God, and general self-reliance.
Kobayashi's Dragon Maid	Heinlein's A Stranger in a Strange Land since both seem to cover a lot about how the daily lives in their societies are shaped from the viewpoint of a stronger immigrant.
Char Aznable from Gundam	The Red Baron from the First World War, since both: have red craft are noblemen are exceptional pilots serve an authoritarian regime are known by popular nicknames (on both sides of their war) that mention redness
The magic in Witch Hat Atelier	programming (in the non-AI world) since both seem to be about carefully crafting well-organized runes to craft anything you can imagine, and all you need is a specific tool and a good instructor. Ok, I say that because I'm a programmer (a white (pointy) hat), but having to complete the circle after lining up components could just be completing a circuit, so it's electrical engineering.
