Maybe he's not caught up in the manga? Or just watches anime?how did you not now that
Well it can't be the anime since Nagato hasn't been introduced yet and if he has not caught up in the manga that I'm perplexed as to why he would stop reading halfway to ask the question when there are more chapters and the Manga is online and avaliable to read at any time. Not paying attention is probably right.Maybe he's not caught up in the manga? Or just watches anime?
That, or he just hasn't been paying attention.
what do you think about the 6 peins?are they real humans or puppets controlled by nagato?
