The guys who hate Erica should remember something. She is a 10 year old girl. A young 10 year old girl who was raised with much pride, responsibility, and noblesse oblige. You guys are literally expecting a 10 year old girl to act like a mature seasoned 30 year old women. Hell, she isn't even old enough that determined her goal and personality in life yet.
I think you guys are expecting too much from a young impressionable 10 year old who has the fate of her people weighing on her shoulders. Right now she's still trying to figure herself out, let alone other people, especially when you consider how empathic she is. If anything, she is too mature for her age to be considering all of these complicated socio-political matters while being inexperienced and equipped with only the knowledge of a 10 year old noble girl.
Like, really, I don't understand what you people expect of little kids. Not all 10 year olds are reincarnated NEETS, Fujoshi's, and Otakus you know.
