After the cancellation of the Edo-Tensei by Obito the fights and clashes evolved quite rapidly.
After freeing himself from Kabuto's control, Itachi tasks himself with breaking the Impure World Reincarnation. He traces Kabuto to the Mountains' Graveyard. Along the way Itachi is found and joined by his younger brother, Sasuke.
They locate Kabuto, but know they cannot kill him if the Impure World Reincarnation is to be released.
After taking precautions to protect himself from their genjutsu, Kabuto takes advantage of their unwillingness to kill him by bombarding them with all the abilities he's acquired for himself: the pilfered abilities of the late Sound Four, the research of Orochimaru, and a Sage Modehe's trained to perfection.
The Uchiha brothers defend themselves, helped particularly by their Susanoo. Ultimately, Itachi traps Kabuto in the endless loop of Izanami.
Defeated, Kabuto is compelled via genjutsu to release Impure World Reincarnation, sending Itachi and the other reincarnated shinobi back to the afterlife.
This allowed the various Ninja troops to move towards the final battlefield where Madara Uchihaa and Tobi(Obito) faced the current five Kage as well as Naruto Uzumaki and Killer B.
During the fight the identity of Tobi was then revealed, under the surprised eyes of Kakashi and Guy, he was Obito Uchihaa!
"Obito..."
"Kakashi sensei, do you know him?" Sakura asked.
Says Sakura with surprised, Naruto also looked at Kakashi with astonishment.
"He was on the same team as me..."
Guy also became serious, he tapped Kakashi's shoulder and raised his thumb with a radiant smile.
"Kakashi, he is no longer the Obito you knew. He's an enemy now! Don't let yourself be down and show the power of your youth."
"Guy sensei you're awesome!"
Lee cried out as all the ninjas gathered in front of Madara and Obito.
"Guy You're right..." Said Kakashi as he removed the frontal protection hiding his Sharingan, then everyone followed Naruto Uzumaki and entered the battle once again.
Just as the Allied Shinobi Forces are about to strike the two Uchiha, both then summoned the Ten Tails, which possessed immense and destructive power, the pair use the beast's power to blast all the attackers away.
The fighting became completely one-sided, with Madara and Obito inflicting heavy damage on the allied ninjas every second.
Under Madara's ruthless strategy, the Ten Tail launched destructive Tailed Beast Ball on cities hundreds of miles away.
. . . . .
In the headquarters
"That far away?"
"It's so much greater than
all the previous Tailed Beasts!"
"What power!"
"It's wobbly from just that little counter..."
"Unbelievable! Such a far-off city
destroyed in an instant! It's been acting strange for a while, it seems to be aiming far away!"
"So all the cities, and people are within its range of fire? Then that means
the evacuated Feudal Lords, everyone protecting the villages...plus all the citizens of
each nation aren't safe?" Says Inoichi who was connected to some kind of sensor Helmet.
Shikaku then raised his head towards Inoichi with a calm facial expression.
"Our shinobi on the battlefield are fighting to protect everyone else...Those two are trying to eliminate our reason for this war."
At the same time on the battlefield the Ten Tails bent down, contracted his huge body and raised his mouth in the air before launching another Tailed Beast Ball.
Neji seeing the direction of the attack couldn't help but stop for a moment.
"That's the direction of--!"
. . . . .
"Th-This is..." Ao exclaimed surprised
"What's wrong, Lord Ao?!"
Seeing Ao in silent, Shikaku and Inoichi immediately understood the situation.
"Please listen to me calmly."
"Here, eh?"
"Well, Shikaku... What do we do?"
"Just keep doing what we must do. It will be our last act, put me through to everyone on the battlefield."
Shikaku then explained his plan to Shikamaru, everything was silent for a moment, then they heard a huge explosion.
. . . . .
In the headquarters everyone was resigned to dying, but suddenly when they thought it was the end, the Ten Tail attack suddenly disappeared and reappeared tens of miles away, then a man with short black hair a male face appeared out of nowhere before the astonished eyes of Shikaku and Inoichi.
"How is that possible?" Saiys they all with a surprised face.
"Shikaku, did you bring some booze with you?"
Hearing this question Shikaku's arms trembled and a smile appeared on his lips.
"How could I not bring a bottle for the Hokage."
