Yeah, I loved the chapter as well. However, it seems that Kishi did an art mistake again with the eyes. But are we certain now that his EMS replaces his MS? Or can he go Sharingan -> MS -> EMS? Or is his only powerup from base Sharingan to EMS? I loved the Hokages, Hiruzen was a bit lackluster...but I don't mind. Loved Minato, think he will get more love next chapter or the one afterwards. Tobirama was an "evil" badass, and we actually got quite a political conversation between him and Orochimaru. But as Orochimaru said, Tobirama was at fault. The star of this chapter was of course Hashirama, the strongest dude in the Narutoverse reminds me of Goku, and hence also of Naruto. Tobito did say that he saw Hashirama within Naruto. However, it was in fact Hiruzen that was called the God of Shinobi and not Hashirama. But I don't mind!
EDIT: A quick check on the Naruto Wiki gave me this: "Hashirama shares the same nickname as Hiruzen Sarutobi and the Sage of the Six Paths. They were each known as the "God of Shinobi" (忍の神, Shinobi no Kami)."
Also who could have known that Tobirama was acting as the older brother?
