Only after saying goodbye to Nagato did Shisui suddenly remember that the Eight-Tails still seemed to be sealed away.
He immediately went to the stone sphere containing the seal. A blade flashed, and the sealed stone sphere instantly fell apart. The fully manifested Eight-Tails burst out of the seal with an angry roar.
Only after roaring did it discover that all traces of the enemy were long gone. Only Shisui remained, staring at it with a strange expression.
This left Killer B utterly bewildered. He hurriedly asked what was going on, only to learn that the war was already over and even Madara Uchiha had been captured.
After hearing Shisui's answer, Killer B sank into utter frustration. He had been sealed away almost as soon as he arrived on the battlefield, before he could do much of anything. Now that he had finally escaped the seal, the war was over. He had never had a chance to show what he could do!
Fortunately, Killer B preferred peace, and the end of the war was a good thing for the shinobi world, so he did not dwell on it too much.
Watching Killer B leave alone, Shisui set off to complete his final task: notifying the Allied Shinobi Forces. He then appeared before the Five Kage, far from the battlefield.
Everyone froze at Shisui's sudden appearance, inwardly startled:
Had the battle already been decided?
Minato Namikaze stepped forward and asked with a slightly anxious expression:
"Shisui, how is the battle going over there?"
Shisui said:
"The battle is over. Naruto and his companion have captured Madara Uchiha and are taking him back to Konoha to deal with him once and for all. The Ten-Tails has also been properly dealt with. The Fourth Shinobi World War is completely over."
Everyone present immediately
