The Ninja's Surprise

Tsunade was a Master at what she did.

She trained so many people.

As a final test, they were told to try and immobilize her.

With a bit of luck, strong rope and good form- they did it.

Once they left- expecting her to get loose on her own- a rival male Ninja showed up and used a strange ability to remove her clothes under the ropes!

She was now naked and immobilized...

"Nice. I can loose a few ropes her and there to have some fun with you."

Tsunade immediately regretted her choice of test.
