>>712967838localization isn't retarded at all. The name "Homura" is completely retarded and unfeminine sounding everywhere outside of Japan.
The name "Pyra", is much more fitting for her character to western audiences.
It sounds playful, youthful, sexy, and has a regal/fantastical edge to it. Perfect for her character.
As a western guy, "Homura" sounds like a Japanese way of saying 'tommorow', or something trivial like that. Not representative of her at all.
