A Hole in the Heart: The Other Jinchuriki
Gyūki notifies B who had stopped for yet another bathroom break that Naruto was far ahead them, to the beast's exasperation Motoi catches up to B and informed them that he had been sent to assist them. As they proceed towards the battlefield, a small faction of the White Zetsu Army nearby plotted an ambush on the duo. Kabuto who had also located B decided to enable another one of his special war potentials in order to capture Killer B. As the coffin emerges from underground — comically uncovering the White Zetsu in the process — the contents of the coffin is revealed to be Fukai, the previous jinchūriki of the Eight-Tails. As the two parties converse, Fukai advises them that he was not in control of his body and that they needed to escape but B notes that without Gyūki, he did not pose as much a threat as he would have. Fukai, however, enters Version 2, shocking B and Motoi.
