Yeah I'd have to agree with this. Not even sure why Hinata-hime was even a ninja to begin with. Her demeanor and overall personality is anything but ninja-esque
Innocent? There's no such thing as innocence when your a shinobi especially in his case, the Saninn are one of the reasons why the leaf village triumphed in the Second Ninja War.
I don't think Hinata's "innocent." She grew up in the Hyuga clan, and you can't really be "innocent" as a member of the Hyuga clan - she probably understands shinobi politics better than most.
