Naruto hits him with the rasenshuriken, they try to seal him and be blocks it before they can. Naruto after hitting him with the rasenshuriken is questioning how it was possible for him to gain a scar if he’s really impenetrable.

This alone confirms that no, the rasenshuriken isn’t penetrating his lightning armour, and that was the whole reason for the “make the Raikage hit himself because that was the only way someone penetrated the armour he scarred himself.“

No he did not regenerate from that otherwise the entire debacle wouldn’t make sense…

Its basic narrative literacy

Shunsui says Hitsugaya will surpass him in 100 years, so do you think that statement extends to his adult form?

I question whether Shunsui’s statement is talking about the power output that comes with growing up or whether that statement also includes the techniques, skills, battle IQ and experience that comes with 100 years of development.
