Silver Carnival Omnidexterity (Earth) gives two extra limbs, not only does that mean double attack rate, but also un-orthodox angle of attack, and limbs with higher strength, speed and endurance (compared to arms). The last bit is cheery on top.
It's better than that, at least later. Hinata has (or can get) long hair. Chakra hair control techniques + this = jyuuken with thousands of limbs. Plus, this should make "full body jyuuken" easier... Actually...
@FixerUpper does this make "fullbody jyuuken" easier?
As to the update:
1) Shells - like in the disney cartoon? I'm not sure how to picture this, sorry.
2) So, unintended consequences. A hyuuga eye stolen, from the middle of Konoha. That's a big blow. One that could, potentially, down the road, lead to Hiashi becoming Hokage.
3) I sure hope there are more Hyuuga watching Gaara now. And some Hyuuga watching Hyuuga who watch Gaara. Because when your operative dies when tailing a subject, it's not a reason to stop watching the subject.
4) Orochimaru, or, I guess, Kabuto, with Byakugan is scary. The scariest possibility? It being implanted in Kimimaro, who has the bone release which seems to be Otsutsuki related, with the eye mutating as a result.
5) At least our strength was acknowledged. Though I seriously don't get "they'll hate me for it". Like, at all. Hinata brought a security concern to her father. He sent an operative to investigate. The mission went FUBAR. How is this at all Hinata's fault? Even irrationally.
6) I like this Hanabi. We should definitely train with her and try and recreate the twin jyuuken style.
7) On the paths - committing to any one path is not the best option, I feel. We should advance on all of them. Right now, though, we need to:
a) Not fall to a distraction
b) Be able to fight Gaara
c) Be aware of what's going on.
