Actually I would think that Minato's space/time jutsu would make achieving sage mode EASIER. He could just teleport away, gather chakra, and teleport back to a fight. Not every opponent can chase after him, after-all. However, I did not expect him to know Sage Mode anyway. =p

Good chapter anyway! Though the encounter felt like it was missing a little flair to me. Good to know that the 2nd hokage knew space/time ninjutsu as well though. Basically proving that Orochimaru's little dolls were shit compared to their real counterparts. Or that Kishi can be pretty dumb.
