Just wondering about two things:
First off, its shows that Naruto has only taken 7 D missions and one C mission. Did they decide to keep the A mission to wave country a secret? I guess its not official because the wave country couldn't afford it.

Another thing is the five parts Kabuto splits data into: Taijutsu, Ninjutsu, Genjutsu, Tool, and Blood. I was wondering about that last thing, blood. At first I thought it had to do with summoning, since those usually include blood. But perhaps its has something to do with advanced blood lines.
