Okay I'm going to post a bunch of facts here about the Yin Seal and its uses because we seem to have some misconceptions among some of us. A few that I've seen throughout this thread have no idea what Hyakugou even is. So let's do some facts:
- The Yin Seal is used by Tsunade to store chakra over a period of time.
- Tsunade can release the Yin Seal to use Byakugou and increase her strength and healing abilities dramatically.
- Tsunade uses the Yin Seal continually to maintain her youthful appearance, but also replenishes it. Sakura says that this means that she can't use the chakra from it as much or as often.
- Sakura can also obviously store her chakra in a similar seal called Byakugou by Shizune. She has been doing it for three years.
- Sakura just enabled the seal and increased her power and perhaps speed to epic proportions.
- Sakura doesn't have to charge the seal now. She doesn't have to hold back.
And now for some conclusions:
- We thought that the Yin Seal must always be visible on the forehead. Obviously not as Sakura has been using it to save chakra over three years and we have not seen it. Tsunade uses the seal to keep up her appearance, explaining why it's always there for her - she's using it 24x7.
- The Yin Seal can therefore be thought to appear when its chakra is used, but probably not otherwise.
- When the Yin Seal's chakra supply is released en masse, it becomes enhanced in a byakugou-like technique.
- Sakura is just using the chakra, she has not completely released the seal.
- So maybe she can enhance herself further.
- Last point, we have no reason to believe it is permanent. As nice as a blue mark would be, I doubt it will be permanent for Sakura since she doesn't need to look like she's 26. She's just 17, after all.
So there we go. The way I see it, anything beyond that goes deep into speculation, prediction, and educated guess.
Nicely said my friend. I very much agree with this.
If she's just using the seal, I'm sure she may have something more in store for us to see. I can't see this being all she has to offer for some reason. I think she has more.
