Well if Sakura's Hyakugou ability does indeed grant her enhanced speed and regeneration of the same calibre as Tsunade's Byakugou it makes me wonder how she would do in a battle against either of the two depicted Raikages. One of them has been proven themselves to be capable of resisting almost every usable attack in existence. Their only weakness being a scar on their chest which they unintentionally inflicted themselves. Then you have the other who is capable of such absurd levels of mobility that not even the Sharingan can follow it; and yet he's stated to possess chakra amounts equivalent to that of a bijuu's and his durability is quite exceptional as well.
I'm not sure. Would Sakura be capable of defeating any of the Kages now? I know this question is diverging somewhat from the currently dicussed topic but I'm just curious on what everyone's opinion on the matter is.
I believe "Hyakugou" is not Sakura's ability, but is the name of her seal. She dips into the chakra reservoir to enhance her strength/speed.
So, what we see in this chapter is the creation of a seal, her ability to tap into three years of saved up chakra. We have not seen the release yet. Right now, there are many possibilities about Sakura's powers and how she will use it. She may have planned on using a couple of techniques once she was finished creating the seal.
It's unclear if Sakura right now knows Tsunade's "Byakugou no Jutsu", as Tsunade said herself that she was the only one who knows that technique. But who knows, maybe Sakura has been training to use it without her knowledge! Many predictions believe she will release Tsunade's "Byakugou".
I also saw a few posts calling Sakura's seal the "Yin Seal". I'm not sure how different Sakura's seal is from Tsunade. Yes, Sakura is using the seal differently from Tsunade, but I do not know if the Tsunade's seal and Sakura's are the same. I believe Tsunade's seal is the "Yin Seal" (can someone confirm this?)
Sakura's seal is not called the Yin seal, only "Hyakugou" from what I've seen.
