Yuhara had actually been thrown around pretty badly. A tailed beast's physical attack power was absurdly exaggerated, something that could be judged from their sizes alone... Yuhara was of normal human height, while the Seven-Tails currently stood between fifty and sixty meters tall. In other words, it was a genuine monster—the kind that could stomp a person to death.
By comparison, the fact that Yuhara had not been killed by a single swipe of its tail already showed how tough and resistant his body was.

A tailed beast's physical attacks were already lethal, let alone a technique like the Tailed Beast Ball. So when they saw it, their instinctive reaction was to retreat as quickly as possible... Dodging it was certainly the right choice. The problem was that they could not dodge it.
The Tailed Beast Ball was this world's equivalent of a nuclear weapon, with an extraordinarily wide attack range. More importantly, the Seven-Tails seemed to intend to release it at close range, with the goal of completely cleansing the weak ninjas below its feet, who were as insignificant as fleas.

Because he might not be able to escape the Seven-Tails' attack range, Yuhara decided to attack it instead. If he could not
