It was confirmed in an interview that the idea for The Last came from SP.that's filler I only deal with the manga and the last.
if you bring up the anime it'll take me a whole weak to round up her misleading character due to the absurd amount of the fillers regarding her.
SP are hinata fans I can even swear that the last was their ideas since it's far from a shonen anime more like shojo.
and the main issue is why the hell does her fillers have better animation than the canon episodes people actually want?
