Veeeeeeeery long and colourful hair (most times). There's blue, red, green, pink, purple and what-do-I-know-how-much haircolours a animegirl could have. WHITOUT EVEN DYEING THEM.

Yeah, it's totally normal that your father has brown hair, your mother has black hair, your brother is blonde, and your having long purple hair, that touches the ground.

Yeah, seems legit.

And it's so logical too that no animegirl or boy ever gets to the hairdresser. I mean, do they do it when we don't look.

I don't think so.
