Loved this one too. This medium to fast paced writing style since the last few chapters suits the series. Good work Kishi Sensei.
Gai is really a beast, Madara acknowledged his power and strength.
The flashbacks were Kakashi's dad's words coming true, Gai surpassed him because he never paid much attention to his strength. That is what I interpreted anyway.
Naruto and Sasuke suddenly get up and move, which is pretty cool as we didn't see any wake up dialogues and stuff which would have wasted panels.
Madara is already looking like trash.
Naruto's entry. OMG!
Naruto has Kyuubi Sage Mode Eyes but no Sage mode markings, some kind of perfect sage mode, I guess. We'll have to wait for 673 now. Also, I think he can control
and manipulate nature energy perfectly now.
The markings on their (Naruto and Sasuke) palms are a real good cliffhanger and I am seriously hyped for the next chapter.
