Ōnoki was considering how to break through the White Zetsu Army's encirclement and join Kakashi and the others.
For now, they could not get through, and more and more White Zetsu were attacking the Second Division.
As for Kakashi and the others, although their numbers were considerable, they were likewise surrounded by the White Zetsu Army, with Impure World Reincarnation Ninja adding fuel to the fire.
So getting them to come to their aid was hardly possible.
As for why Mifune could lead the Fifth Division through the enemy encirclement while Ōnoki and the Second Division could not...
The first reason was that Mifune and his men had caught the enemy off guard. Before Obito Uchiha could even react, they had already joined Kakashi and the other surviving troops.
The second reason was that Mifune commanded the entire Fifth Division. Although their numbers did not exceed twenty thousand, they were not far short.
As for Ōnoki, the Second Division had split its forces before coming to reinforce the Main Battlefield. Kurotsuchi had taken the other half of the ninja force to reinforce the battlefield in the Land of Waves.
After all, Hyuga Hiashi's side genuinely needed reinforcements as well.
So Ōnoki had effectively brought only a little over ten thousand ninja to reinforce the Main Battlefield.
They had fewer men, and the enemy was prepared.
That left them unable to join Kakashi's Third Division as easily as the Fifth Division had.
Faced with this situation, various thoughts passed through Ōnoki's mind as he considered what to do next.
Should they force their way through the enemy blockade and join their allies?
Or should they establish defenses where they stood and fight the enemy directly?
Ōnoki hesitated. Both decisions had their advantages and disadvantages, and he found it difficult to decide
