My favorite thing about Fate in every single NanoFate doujin in existance is that, by all means, she SHOULD be the typical cool, collected beauty, yet in just a couple of pages it's made obvious she's just a giant nerd
She spent four years in almost total isolation with a parent who hated her, with nothing but books to entertain her, plus, she was a math prodigy, like all child mages in the series. What else could she be other than a huge nerd?
