S ranked sharingan jutsu training

Rika slowly opened her eyes. She always felt tired, and had a hard time getting up some days. She knew this wasnt healthy, but she just couldnt help it. Looking to the window, she noticed it was around nine due to the angle of the sun. Rika forced herself out of the bed and rolled out. She lived alone now, and it hurt her just to walk around in her home. She missed company, but knew she wouldnt be much fun anyway. She walked through her home and wondered at how empty it had become. So much stuff that had been in here had hurt her and so she had gotten rid of it. Rika stepped into the shower. After allowing the water to heat as hot as her body could stand it, she stepped into the water. The hot water streamed down her body in predictable patterns and she could trace the exact path with her finger due to the sharingan in her eye. These cursed eyes again. They would never leave her alone. Every time that she noticed what they were doing it hurt her. She was never going to get away from the power they held and so she tried to learn to deal with that pain.

After her shower she, she got out and got dressed. She started brushing her hair. This process normally took a while due to her long hair but it was abnormally easy today and it dried quickly. Once finished getting ready, Rika left her home and walked through the village. She moved quickly but her eyes noted every face that moved through the street. Another uncanny ability of the eyes. She noticed they were all people she didnt know. All of the people from her childhood had dissapeared from her eyes while she was in the anbu, and, for all she knew, could be dead. The only person she had kept with her through all the time was dead and was never comming back. She decided not to walk on the street and jumped to the nearest roof. She jumped from roof to rood and made it to the training area in no time.

Once she reached the training area, Rika had already made up her mind she was going to master this new jutsu today. She had worked on the basics of it already and had the hang of starting it. Today it was going to be finished. She knew she only had a few tries so she made them count. She activated her sharingan and her eyes took the normal form. Three black circles overlapping and a dot in the center. She then started to focus on a tree in the distance. She used the sharingan eye to focus her chakra into a swirling mass similar to rasengan. However, this wasnt near her body. Rika focused even harder on the spot and crushed her chakra closer and closer together. This took alot out of Rika and she lost it. The chakra swirled and lost its power. Rika was tired so she sat down. After a pretty long wait, she stood up again and started the jutsu again. She focused on swirling the chakra and moved the chakra around. This time, she collapsed the chakra in on itself until it reached nothingness. The middle of the tree collapsed in on itself and completely dissapeared. The tree was not only destroyed it just ceased to exist. Rika collapsed. She was so tired she could barely move. It would take more practice to make this jutsu not take so much out of her, but Rika had mastered the jutsu and use it when she wanted. Like other sharingan jutsu she named it after a diety. The name of this technique is Kamui, or God's Magetsy.

Figuring that she needed to make it usable a third time, Rika decided to come back and try it again without knocking herself out. She stood in the middle of the field and stared at a tree across it. She activated her sharingan and it took her normal magekyou shape and turned a dark red. And so, she started her training again. She began to focus her chakra into a tiny ball inside the tree. The ball began spinning, slowly at first, but then it got faster and faster until it was similar to a rasengan. This chakra was invisible however and wouldnt do any kind of damage until the jutsu was completed. She swirled the chakra even faster and began collapsing it. A clear ripple in the tree appeared and she noticed it went wherever she looked. This could be used to target better. Locking back onto the tree, the collapsing continued until it went in on itself and the tree's trunk ceased to exist, blowing the shattered pieces away. This still took a tole on her body but she continued. Starting again right away, Rika concentrated on another tree, and again began to swirl that chakra. She moved her eyes around this time and watched the swirl go wherever she made her eye movements. She then focused back on another tree and collapsed her chakra. It once again went in on itself and whatever she looked at ceased to exist. She wondered what effect it would have on a human body; however she wouldnt test it until battle. After the second one was finished Rika was extremely tired again, but she promised herself she would get three in this time, so she tried again. Going through the steps again, Rika focused on her next tree target. She collapsed the chakra and once again the jutsu succeeded. Rika didnt get to admire her handywork however because she collapsed from exhaustion. She awoke a few hours later and walked slowly back to her home to get some rest.
