She makes me think of a character from a webcomic i read called
Gunnerkrigg Court, Katerina Donlan.
Kat's a normal human, an engineering prodigy who repairs and makes robots, robots who grow to see her as an Angel. As the comic progresses, Kat's technical skills and comprehension of basically any kind of systems steadily increases. IDK if there's some weird thing where the robots' religious belief in her is having an effect or if its something else, but at one point a different character who is sort of between this world and an invisible spirit world encounters Kat and she looks like this:
From a fantasy standpoint, I view Ame's character similar to that image, unseen and invisibly hidden behind a cute girl next door, very slightly pon but smart gremlin gamer detective. Amelia Watson is inevitable. And thankfully, apart from Small Ame, she's a sweetheart and has adopted an admirable profession focused on truth and justice... while still being a bit of a renegade and unpredictable.
