Shitsuya was dropped off at his grandparents house before his mother left.
"Hello Shitsuya~" His wrinkly grandmother said in as she bent down and pinched his cheek.
"Let's go see grandpa~" Shitsuya nodded and followed her.
His grandparents lived in a huge house with a big yard and a pond.
Sat on the back porch and smoking a pipe was a white haired old man.
Turning around his cold eyes bore into him before growing fervent a second later.
"That will be all Miyuki." His grandpa waved away his grandma who promptly left leaving both of them alone.
Putting on a kind smile? Shitsuya grandfather motioned for him to sit next to him.
Shitsuya took a seat while keeping a bit of a distance, his grandfather however proceeded to wrap an arm around him and bring him close.
His grandfather ran his hands all over his small body while staring at him with increasingly brighter eyes.
'Am I getting molested right now?' Shitsuya thought as a shiver ran down his spine
Just when Shitsuya was ready to start running his grand father placed his palm on his forehead.
He feld like his chakra was burning as some foreign force hijacked control of it.
His chakra was slowly forcefully moving towards his eyes and his heartbeat sped up.
Shitsuya struggled to try and get away but he couldn't but up even the slightest bit of resistance.
He could only watch as the second worse out come happened, his Sharingan was revealed.
"Hmm, relatively stable, it's probably been well over a year since awakened." His grandfather slowly revealed his secrets.
"From the traces of chakra network damage around the eyes looks like your mother doesn't know about your Sharingan. How incompetent, if not for your good, a genius like you would have been lost." His grandfather said before before removing his hand.
'From the academy reports and his mother and father's talents I thought he would be another disappointment but it seems I am mistaken.'
'Although awakening the Sharingan at a young age is not necessary to have great future prospects, even the former clan leader awakened only when he became a teenager but awakening the Sharingan at a young age is a good sign.' Mitsuki thought as he stroked his chin.
He couldn't trust the nurturing of such a talent to his incompetent daughter who couldn't even awaken a Sharingan or have any achievements even after his personal nurturing.
He should train him personally but he knew his daughter would never agree.
A cold light flashed through his eyes and he had a ruthless idea but he quickly dismissed it, talented or not she was still his daughter.
'I'll have to take the soft approach.' he thought.
"Come with me." Mitsuki stood up and said before walking towards the pond.
Shitsuya silently stared at his back with his Sharingan before deactivating it and following behind.
Arriving at the pond, Mitsuki turned to Shitsuya and said, "Although the Uchiha clan is most famous for our Sharingan, we are also famed for our prowess in fire Jutsu."
"Today I'll be teaching you our clan's signature fire Jutsu. Use your Sharingan to observe." Mitsuki said.
Shitsuya hesitated for a moment before obediently activating his Sharingan.
In a situation where someone had him by the balls like this it was best to feign obedience while looking for a chance to counter attack.
Satisfied with Shitsuya's attitude, Mitsuki turned to the pond before preforming a set of hand signs so rapidly his hands looked like a blur before spitting out a large ball of fire from his mouth that covered the entire pond.
"Your turn." Mitsuki turned and said to Shitsuya.
Shitsuya silently nodded and took his grandfather's spot in front of the pond.
Mitsuki watched closely as Shitsuya preformed the hand signs.
Not all Sharingan were created equal even if they possessed the same number of tomoe.
Some three tomoe Sharingan could even resist in the face of the Mangekyo Sharingan while others were only marginally better than a two tomoe Sharingan.
Wanting to test out Shitsuya's single tomoe Sharingan he preformed the hand signs at a speed where only the peak of the single tomoe could perform.
As Shitsuya finished preforming the handsigns and preformed the fire ball Jutsu a large fire ball almost as large as the entire pond was produced.
Seeing the result Mitsuki shook his head.
It wasn't because Shitsuya made a mistake or because his performance was lacking, Shitsuya preformed the Jutsu perfectly.
That should be good news and mean that Shitsuya's Sharingan was well developed however Mitsuki was no greenhorn.
He could easily tell that Shitsuya already knew this Jutsu.
Almost everyone in the Uchiha clan knew the fire ball Jutsu so someone with a Sharingan would have to walk while looking at his feet the whole time in order not to copy it.
That didn't matter, If he knew the Jutsu already, all Mitsuki had to do was teach him a Jutsu he didn't know.
As to which Jutsu, Mitsuki quickly came up with a candidate, he would teach his grandson his favourite Jutsu, the hiding in ash Jutsu.
This Jutsu earned his favour long ago due to its utility, not only could be used to create a cover for an escape or to create an opportunity to attack by blinding an enemy, the large cloud of ash created could also be easily ignited for a large fire explosion.
Having decided his next course of action, Mitsuki approached Shitsuya.
Patting his shoulder he praised him, "Well done, you are very talented."
Shitsuya only stared up at him silently in response.
Coughing in his hand Mitsuki said, "I was planning on spending the entire day teaching you but alas you learned the fireball technique too quickly, would you like to learn another Jutsu?"
Shitsuya looked at him silently for a few seconds before nodding.
Mitsuki smiled to himself, it looks like the allure of learning new Jutsu couldn't be resisted by even his strange grandson.
