In the last page of 666 madara said i've seen you somewhere but when is that does this mean madara knows gai loong time ago or in thsi war or what plz explain!
I do hope we get to see the power of the 8 gates.
I remember back during the Chuunin exams when Gai explained that opening the 8th gate would grant you power and i quote " Greater then that of a Hokage, at the cost of your life ".
It makes sense. Madara hasn't acknowledged any of the ninja on the battlefield other than the main characters, also Guy is at a sizeable distance in that scan- it looks like it's coming from the Hachibi if anything.
