Chakra enhanced strikes, it is canon that Itachi could do it at seven... to destroy a boulder. It wasn't Tsunade level but it was present. Naruto technically did this when he used Kurama's chakra. In my mind, it is a basic technique but the level of it and the skill it unique to Tsunade and Sakura, a medical version of it...

I suck at action but I think in this case I did a damn good job, and I finally flesh out Mika's skills out. We get to see what he is capable of, something I was unsure of before but know now. I drew my inspiration from Shikamaru and Kakashi's fighting styles, two characters I dislike though I adore Kakashi's fighting style.

"Come at me with the intent to kill!"

Mika shivered just a bit as he watched leaves descend on the breeze. Kakashi was in front of him, smiling falsely with his body entirely at east. 'Other than the assassination and class spar and fighting Kabuto to learn evasion, I have never been in an actual fight. This is... not going to be easy. Just use my brain... just use my brain.' Without hesitating, he threw a series of kunai at Kakashi, who caught them easily, just as Mika moved with a shushin to reach Kakashi with his blade out. Kunai met tanto, slash, slash, stab.

Mika started to sweat almost immediately in the cool air as he fought Kakashi. His mind moving at a million miles an hour, eager to show what he could do. 'I need to push all of my skills together... but how?' Without thinking, Mika channeled chakra into his leg and kneed upward, which Kakashi blocked with his own knee.

The man's eyes went wide, he cringed ever so slightly. "That actually hurt, very nice. Not everyone can augment their physical strength with chakra, a medical ninja indeed. Tsunade would be proud."

With flipped back, throwing shuriken out at Kakashi before Shushining away into the woods around him. With a slightly rusty hand, Mika started to set up traps, moving from place to place with a body flicker not even bothering to mask his movements. He was going to do well, show Kakashi what he had and the man would hopefully recommend him for Chuninship.

'My knee stings, that strike was really hard. Not Gai hard, but still...' Kakashi said, smirking, waiting for the boy in question to get done with his trap making. He had no idea what the boy was doing exactly, but he knew enough about medical jutsu to know it wasn't poison. That was a bit too advanced for him at that point, so really he didn't have too much to worry about...

Or so he thought before a kunai bearing an explosive tag rocketed at him.

Throwing a kunai, Kakashi forced the explosive tag to pin against a tree before it exploded, causing the tree to crumble... and five other kunai to come at him from various directions. Want to laugh, Kakashi leaped up, dodging the various weapons with grace and ease and -" UH!" He said, not entirely dodging the strong fist that grazed his cheek. Mika was there, looking at him with calculated efficiency, fist raised.

As Kakashi flew back, away from the boy, he was forced to dodge in mid-air four more kunai, this time grabbing one and deflecting them all, only for Mika to be there again, foot flying towards Kakashi's chest, doing more than grazing it. The chakra-enhanced strike sent him flying back, his ribs aching.

"How'd you do that, your shushin couldn't possibly be that advanced..." Looking around, Kakashi quickly found his answer in the number of Kunai around. "You replaced with a kunai, replacing with something that small would require extreme chakra control. Very, very good indeed, medical training was not wasted on you at all." Mika then did something that surprised Kakashi. Going through a familiar set of signs, he said. "Hidden Mist Jutsu." And breathed out a long stream of Mist that covered the entire clearing. "Very, very good. You mastered it well, but it is not quite as thick as Zabuza's, and your no master of the Silent Killing technique." A dozen rocks, from each and every direction, flew at Kakashi, he easily dodged them all but one, one go through and smacked into his left bicep. 'If that had been a kunai, I would have been in real trouble, that was where an artery is. His mastery of the shushin, reminds me of what Shisui was capable of, less refined but the boy's chakra control and skill with evasion as a medic make him a natural at using it for things like this. With the silent killing, he will be exceedingly deadly...I may have made a monster.'

A kunai flew at him once more, he heard it and naturally caught it, only for it to have a light bomb that exploded, searing into his eye. He could not help but flinch and recoil, the pain intense, so intense he barely dodged Mika's sword swing that caught his hip pouch and cut in half his Icha Icha."

"Damn." The boy said, panting.

Kakashi raised one hand, the other rubbing his eye. "Enough... you're good, very, very good for your age and in general. You are easily Chunin level, hell I would say you are as good as Sasuke, just in a vastly different way."

Mika nodded, releasing the Mist.

Across the clearing, he saw a pissed off Sasuke and Stunned Sakura. "How did you do that? I thought you were a medic?" Sakura asked.

Mika shrugged. "I refuse to be helpless, I have been training and I was already really skilled in the academy. Think how much better I would be if I had someone sparring with me... Kakashi, I am asking a lot but can you arrange for me to get a sparring partner? Beyond Kabuto who only helps me with my evasion? I am basically self-taught in more advanced taijutsu and kenjutsu."

That only made the boy's skills more impressive to Kakashi. "I will do what I can... you are good, kid, do not doubt your skills. If you master that trick with the shushin in the Hidden Mist... you will reach Jonin in a year, tops."

That made the boy flush.

Kakashi wondered how much stronger the boy would have been with a real teacher, and maybe a sparring partner. It would be amazing to see...and it was totally worth the death of his beloved book.

'I was going at low jonin level, but for him to manage to force me into such a situation... with his limited experience. He reminds me of a Nara...he reminds me of Shikaku. Note to self get his IQ tested... The kid's strategy was masterful, interesting and methodical. It took advantage of every skill, every ability, and even my movements. It was beautiful. He really is going to end up dangerous. Lucky he is on our side.'

Chapter end, tell me what you think in the reviews.

This was beyond fun, interesting and perfect. No he is not OP, Sasuke was able to force Kakashi to take him semi-seriously and used a fireball jutsu. Shikamaru, a worthless lazy bum, almost bested a jonin level Tayuya with just strategy. Neji barely bested the Jonin level Kidomaru. Intelligence is key, as are tactics and Mika is a master strategist. That is his greatest asset, his mind, and determination...

Love, your Ninja Overlord,

Mika.
