@eaglejarl @Paperclipped @Velorien : Do we know whether Snowflake can use Kei's Shadow Element techniques? Has Kei told us anything on the subject? (If she hasn't, I am not suggesting that Hazō should ask - that seems like treading perilously close to Nara secrets, and the kind of thing we should probe at in a proper plan - but if she doesn't consider the answer secret Hazō might already know.)
Context here is that back when we were asking Oro about how non-standard elements worked, he said this:
The other interpretation is that what Oro is saying is a trivial inference is that the Shadow Element works because it draws its "seed" from the entities on the other end of Thinker bloodlines. Oro was describing nonstandard Elements as working because the bloodline draws in a tiny amount of nature chakra to create a seed of the Element, which then allows aspecting the rest of the chakra. Given that Kei also has a Thinker bloodline, it doesn't seem unreasonable that what he was actually saying is "you have to have a Thinker bloodline to use Shadow Element, but it doesn't have to be the Nara's", and he was calling that a trivial inference because he's Oro.
But in that case, it raises the question of whether Shadow Clones - which lack the bloodline in question - can use techniques hypothetically dependent on it. It wouldn't be definitive if they could - there are other explanations - but it would be evidence towards Shadow Element being learnable by anyone. And if they can't, I think that would be very strong evidence that the Shadow Element requires a Thinker bloodline to use.
As an aside, @Shrooms, you were talking about the Nara teaching all their genin Shadow Element. It occurs to me that Shadow Element not being a bloodline doesn't necessarily mean they're not born with it; if it's genuinely a human-learnable Element just like the other, Nara could be born with it just like other ninja are born with Fire or Earth, and even if it does depend on having a Thinker bloodline the affinity being heritable doesn't seem out of the question.
Context here is that back when we were asking Oro about how non-standard elements worked, he said this:
One interpretation of this is "The Nara already have a Thinker bloodline, so they can't also have a Shadow Element bloodline, so it should be trivial to infer that Shadow Element is not a bloodline Element". The problem with this is that it requires the Nara to have been hoarding an entire human-learnable Element from everyone else for hundreds of years, and somehow for the secret never to have got out. It's possible, certainly, but it doesn't seem that likely."Your sister learned the Nara's Shadow Element, I presume?" Orochimaru asked, as he inspected various vials. "They are the only non-standard element users in Leaf, and I do not believe you have traveled far enough to find another clan so willing to share their secrets."
"Yes, Lord Orochimaru."
"The Shadow Element is not a typical example, as it is not anchored to the Nara's bloodline. But that should be a trivial inference, given that you already know about the Five clans.
