Hello. I am not reading the manga (yet) but I have a question. There is a lot of fanart of Madara's human form, but Madara has said that when he transforms into a human, there is some resemblance with Natsume. Does this happen in the manga? And if it doesn't, does anyone know where this human form originated? (I am talking about this one, by the way http://www.zerochan.net/861314#full ) Thank you.
It's just like MM-Rosiie said (though I think that the girl Madara transforms into isn't exactly what Reiko looks like, just really looks like her) but this form you linked is a design made by a user in pixiv. At least I think so, since I saw that picture there :) If you want, I can link you the picture (you're only able to see it if you have logged in pixiv). I didn't say anything new, but hope this helped even a bit!
