Minato is filled with regret during his confrontation with Obito. He thinks if only he had recognized Obito as the Masked Man during the assault on the Hidden Leaf Village, he could have stopped the attack, and maybe Kushina would not have died. The next day is the anniversary of Minato's and Kushina's deaths. Obito taunts Minato as a weak shinobi and seals every shinobi inside a barrier in order to destroy them all!
I sense two Nine Tails,
one light and one dark, yo!
أشعر باثنين من الكيوبي، أحدهما نور والآخر ظلام، يا صاح
Los Kyubi de la luz y la 
oscuridad juntos están.
Los Kyubi de la luz y la 
oscuridad juntos están.
Percepisco due Volpi, 
una di luce e una di oscurità, yo!
