Noboru woke up in the dead of night unable to sleep. In just a few hours he'd have to activate his doujutsu. He thought back to when he was younger, and when he watched his sister do the same.
__________________________________________
"Mikan, do not stop now; I will not accept failure!" Sejin yelled.
Mikan was on her knees struggling to catch her breath. She looked up at Sejin with disdain, and hatred in her eyes. She tried to get up, but she fell again coughing, and wheezing for air. She looked at her little brother Noboru and smiled. He was on the sidelines watching her attempt to awaken the Kiidogan.
The lead Jonin Rubin was also interested in the Kosutta clan's visual prowess. As expected of every member of the Kosutta clan Mikan had to endure a grueling sparring match with the head of the clan on her 13th birthday. On the other side of the building watching the bout was Noboru's sensei Minaka, Minori and Natsuki were present as well. The three of them were Kosutta genin that had already undergone the Mock Exams, and unlocked their Kiidogan.
Sejin would push her to the breaking point physically, and mentally, at which point her body will have one of two options. Either it will awaken the Kiidogan as a last resort... or it won't.
Noboru, and Mikan being the heirs in the clan, desperately needed to awaken the doujutsu. Noboru watched his sister Mikan with content as she stood back up. She looked back at Sejin before charging at him as fast as she could.
She sent a few kunai flying towards his chest.
"Infinite Rotation!" Sejin yelled, and his hand began to twist chaotically. Every kunai that encountered Sejin was deflected spiraling through the room destroying wood, and cracking the ceiling.
"Air Current Dance: Quiet Step," Sejin stepped forward, and in an instant he'd closed the distance between himself and Mikan.
The quiet step allowed the user to close small distances between themselves, and their opponent by shrouding them in a thick black mist, and briefly enhancing the body allowing for a single quick step toward an enemy.
With his rotation still active he brought his fist straight into Mikan's stomach.
"Too easy." He muttered before hearing his own bones crack as Mikan's knuckles crushed into his face. Sejin flew hard to the other side of the room...it took him a second to catch his breath before standing back up.
'I see.' Sejin thought. 'She used the kunai as a distraction while I focused my attention on them. She used a shadow clone to charge me while the real Mikan hid behind it waiting for an opportunity to strike.'
"I've underestimated you Mikan," he said glaring at her.
Sejin took out two smoke bombs from his pocket. He threw them up and used wind style to break them.
"Ninja Art, Wind Nature Rotation!" He yelled.
Instead of completely dispersing, the smoke from both bombs remained confined in two finite spheres spinning incredibly fast. Sejin's chakra control was so developed that not only was he capable of spinning the spheres, but he was also capable of moving them.
Rubin the lead Jonin began to worry.... he thought about calling out to Sejin to stop before he felt a tug on his leg.
"Don't worry Rubin. He's not trying to kill my sister... You see that smoke?" Noboru said pointing at the white spheres, "if he was he wouldn't have used smoke bombs in his rotation. The whole point of the smoke is to make them easier for Mikan to see."
After hearing Noboru's explanation Rubin was relieved, but a bit embarrassed he couldn't figure that out for himself.
'This kid.' He thought. 'Is something else.'
Rubin focused his eyes back onto the fight. Sejin slammed his foot into the ground and threw his arms forward, and without hesitation the deadly spheres of smoke went flying towards Mikan.
Mikan ran avoiding the spheres the best she could; jumping, and gliding through the air as often as possible. Both the spheres of smoke, although guided by Sejin, worked interchangeably together creating a devastatingly challenging opponent. Sejin focused his chakra, and the spheres moved even faster.
Mikan felt the skin on her back twist into a knot before being ripped off her body. She screamed in horror, but it didn't stop her. She put her hands together and managed to wield the proper hand signs.
"Wind Style: Retrieving Wind Technique!" A gust of wind beneath her feet appeared, and propelled her far from the white sphere of smoke. Mikan was incapable of slowing herself down; she looked ahead, and saw she was flying into the second white sphere.
Noboru watched his sister maintain a collected look as she was right between both of Sejin's destructive weapons; one in front, and one in back. Regardless she wielded more hand signs.
"Shadow Clone Jutsu!" She yelled.
A perfect clone appeared in the air beside Mikan, and without hesitation it grabbed her and threw her out of the way of the sphere leaving the clone to take the impact. Mikan flew into a nearby wall, and both spheres collided sending sharp gusts of wind all over the room.
"Ninja Art: Earth Style, Mud Wall" Rubin yelled as a giant stone slab erupted from the ground protecting both Noboru, and himself.
He looked at Noboru with concern as concentrated wind decimated the entire building. After the spheres disappeared, Rubin receded his mud wall. He studied the room waiting for the smoke to clear. Waiting to see what happened.
'There's no way she got out of that unscathed. The impact from hitting the wall alone should have decimated her body...Unless.'
The smoke cleared and on one end Sejin was bent on one knee gasping for air. On the other end Mikan was standing straight... but something was different about her. She had a blue aura channeling through her body. It was wicked, and intense...It wasn't entirely chakra...
"A lightning shield?!" Sejin yelled, "Rubin, what exactly have you been teaching her?"
'Fire, Wind, Lightning, Water, Earth.' Noboru thought to himself. "Every chakra nature has an opposing counterpart. Earth will always beat Water, and Water will always beat Fire; the same concept should apply here; wind always beats Lightning... but then how did she...?"
Noboru crossed his arms quizzically for a moment. Rubin watched the boy struggle to figure it out.
"Oh...so there is something you don't know huh?" Rubin asked with a sarcastic grin on his face, "Noboru, it is true that Lightning release is mostly inefficient against Wind release... that's because wind is a natural electrical insulator. At the same time however, lightning can potentially surpass the penetrative force of wind by increasing its vibration frequency high enough. This allows for lightning to oust wind to some degree... it's likely your sister was saving this jutsu for this very moment as it was the only defensive technique at her disposal that could've deflected the blast."
"To be gifted in two chakra natures, and at such a young age, " Sejin said. "Your defense is ingenious Mikan. I'm quite surprised, however you can only maintain your lightning release at such a frequency for so long..."
Mikan ignored him, and charged across the room, and tried to punch Sejin in the jaw, but he was too fast. He was already sending sharp gusts of wind through his palms at Mikan's body.
Sparks of lightning, and wind flew with each matching strike. Multiple Kunai in Sejin's pouch then erupted in a flurry of chaos, and began to spin wildly around the two combatants. Sejin used them like coordinated drones launching them at Mikan one after the other.
Mikan took out her own kunai, as well as some wire strings, and danced through the air managing to counter every kunai thrown at her all the while fending off Sejin with his own taijutsu attacks.
"Her taijutsu is incredible!" Rubin said, looking down at Noboru, "even I didn't teach her how to do that."
Noboru, and Rubin continued to watch Mikan as she flipped through the air, overpowering Sejin. Eventually the kunai weren't spinning anymore. Confused, Sejin jumped back a few feet and tried to launch all the kunai directly at Mikan, but they wouldn't budge.
He looked up and saw that he no longer had control over them. They were suspended in mid- air loosely attached to wire strings, and the worst part is they had paper bombs attached to them. There was a long-winded silence as both combatants stared at each other. Noboru began to wonder if his father was still going easy on her.
He began to imagine... the best of the clan... outsmarted by a mere 13-year-old girl. Mikan launched all the exploding kunai at Sejin, and she wielded the right hand-sign signaling all of them to explode.
"Kiidogan!" Sejin yelled, awakening his doujutsu. Noboru looked on as the explosions from the paper bombs began to collapse on themselves. Sejin was moving his hands back and forth again containing the explosion into a finite sphere of white spinning wildly -just like he did with the smoke spheres earlier.
"Enough of this!" Sejin yelled, "Wind Style, Retrieving Wind Technique!"
Out of nowhere Noboru felt a gust of wind beneath his feet. Rubin tried to reach out, but Rubin himself felt a gust of wind hit his chest sending him against the wall. As he had been lifted up, and thrown high into the center of the room between the two combatants. Again, Sejin stomped on the floor and threw his arms out forcing the exploding sphere towards Mikan's little brother.
"Wait!" Mikan yelled as the spinning flash of light began to consume him.
The last thing Noboru saw was Mikan's eyes...They were purple...'Those eyes' He thought. "I guess that's good." He said as everything faded to black.
