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.

Para teleportar tudo, precisaríamos
de um de nós para cada bomba.
