I don't know if I've missed this somewhere in the manga... or if it's addressed in the anime, and this is utterly pointless, but...
I was wondering - is Bianchi supposed to be a first name or a surname? Because I've been reading, what, almost-300 chapters under the impression that it was her first name. Then I looked in up on
behindthesurname, which says that it's an Italian SURNAME.
Since Gokudera decided to take his mother's surname (right?), I presume Bianchi has something different. And because the Japanese tend to call people by their surnames, well, it's possible that Bianchi is the family name...
Or perhaps this is something everyone else already knew. So, yeah, Bianchi: first name or surname? Do we know what her full name is?
