Manga chapter 671 :o

[Zabuza]

Holy s#1^ this one was AMAZING. One thing that still makes me wonder is what the heck happened to rikuduo's brother.Any answers/theories? and i really do not agree with the concept of giving sasuke the 6 path's power and some people are theorizing that madara is the reincarnation of Rikuduo's brother (I hope this is not true cause i want them to do a spin off  about the rikuduo and his bother O.O)
