Spoiler:

Hana stood at in the training grounds. She was close by a small stream. Fish glinted as they darted past her shadow that was upon the water. Hana watched them closely for a moment. They looked like glints of jewelry. After a few moments of looking into the water she turned around. It was time to start training after all.

She then began her first jutsu. She began to form bone armor underneath her skin. Basically she would use it to protect her vital organs. Meaning her ribcage would be formed so it would be more of a wall instead of a cage. There would be no way to penetrate. Her skull did the same. Her bones would become as hard as titanium.

She had done this before a few times, but she needed to master it. She wanted to be able to form it before every fight. This would give her amazing protection. She was able to form extra bones, repair them, and strengthen them. This would help her so much with this technique. Hana began to grow faster and faster with each time she redid the jutsu. Finally after a good hour she was able to form it at the speed she wanted.
