Itachi is alive, dont want to capture 8 tails, so he fight to death against B 1on1
place: Kumo training zone
Itachi has mangekyou and is completly healthly....
B can use max power of 8tails
my opinion: Hachibi is good, but we saw that Amaterasu from Sasuke got him + Itachi has Susanoo too.... for me
