if pein can absorb wind(rasen shuriken) he can absorb fire amaterasu can be extinguished. tobi warped it away...ninjutsu doesnt work against pain...legends are sumtyms bogis. they said susanoo couldnt be broken and danzo whiped it with wind.give a explination why pein cant absorb amaterasu
No he cant absorb it.
Madara warped it away he didnt put out the flame(thats not the same thing)
The reason why pein cant absorb it is because its not an ordinary chakra based jutsu..simply that. I will say pein could keep it away from him by pushing it away using shinra tensei. And thats also what danzo did, he pushed it away from him. Kinda like gaara blocking it with sand.
But only that caster can stop absorb it.
