Medaka
It was a brutal battle. With every exchange of blows, walls collapsed and the ground shook in fear. This was a battle of masters, so there was bound to be property damage. At the very least, no one got in their way.
For every blow she delivered to him, he returned 20. He was as fast as Shinobu and was more than skilled enough to put that to use. Even so, she had the advantage when it came to stamina. While his damage stayed, hers faded thanks to her healing factor. He had speed. She had endurance. It was a battle that could last forever.
Which is why she decided to use that move.
She stood atop a building, planning on using gravity to aid her attack. He stared at her, understanding this to be a do or die move. But even so, he awaited the attack with courage. She shot downwards, shattering every window that she passed on her decent and breaking every bone in her body. When she turned around, it seemed he managed to dodge the attack.
"I am impressed," she said, turning to him with a satisfied smile. Blood dripped from her arms and legs. An experinced fighter could see her condition, so there was no doubt Ito could assess her pain. "You are the first person to dodge that attack."
She was painting, tired from the battle. He could finish her off now if he had the strength. If not, she would begin recovering. Such is the nature of her gift from Shinobu, the promise to live.
She slowly walked over to the ninja and reached out her hand. Each step felt unimaginably heavy, even with the pain receptors in her brain turned off. With a gentle smile she said, "how about we get you to a doctor. It seems we went a bit overboard in our sparring session."
