7 It All Starts At 0

Charging at each other to commence a hand to hand battle, Geto suddenly jumped into the air and summoned a giant hawk. Holding the giant hawks feet, Geto suddenly turned around and teased Akira with his tongue, leaving him dumbfounded.

"Oi oi oi, where are you running off to?!"

"It's not running patriarch, its flying." Mocked Geto. "And now's not the time for us to fight, I have more important things to do than dying here today."

"Tch, damned brat."

...

Exiting the hospital, Kakashi and Toge met up with their father and began heading home. "How was your first time fighting a cursed spirit, a grade one no less?" Questioned Akira. "How should I put this... It was quite easy, " answered Toge.

"Yes, I kind of expected more, but it is what it is." Shrugged Kakashi. "Anyways, let's head home, I want to practice some sword techniques."

Taking the uneventful journey back home, Kakashi and Toge went on about their day, not knowing that their father almost clashed with Geto.

...

Having reached back to the Inumaki estate, Kakashi ran to the dojo to begin familiarizing himself with his sword. "Let's see, I know I said I wanted Ichigo's sword, but I wonder if I can use a Getsuga Tenshō..."

Standing with his feet a shoulder-width apart, and placing his dominant foot forward whilst the other is turned 45 to 90 degrees away, Kakashi held the sword above his head and slashed downward whilst yelling "Getsuga Tenshō!" but nothing out of the ordinary happened besides dirt getting flung from the slash.

"Huh??" Staring funnily at his sword, Kakashi felt like a chuuni going through adolescence. "Guess that didn't work..." Hours later of repeatedly slashing the katana, Kakashi still made zero progress. "Son of a bitch." lying down on the floor of the dojo from exhaustion, Kakashi thought of what he could be doing wrong.

'Can it even do anything besides slashing, or did it just not come with the fucking technique?' Looking at the sword for one last time and brain storming ideas, Kakashi finally thought of something constructive, then facepalmed himself for his stupidity. "Wait, maybe I should try infusing my cursed energy into the sword..."

Imbuing the katana with his cursed energy, Kakashi finally saw a reaction from his sword. After Kakashi's cursed energy permeated the sword, the reaction from it was not what he expected, as it was quite different to Ichigo's. It was still the signature black, but their was a bit of lightning buzzing about the swords blade.

The lightning was white in color, and it seemed truly spectacular encircling the swords blade. 'Alright, lets just send a little slash towards the dummy.' Getting back into position, Kakashi repeated his overhead slash once again, this time, with cursed energy imbued into the sword.

Slashing forward, Kakashi's blade sent out a crescent wave of energy. This energy wave however was so strong that it not only penetrated the dummy, but also penetrated the dojo walls and smashed directly into the carp pond outside. "I'm fucked."

...

Location: Akira's office

Standing in front of his father, contrary to what he believed, his father wasn't upset about smashing his carp pond, but was quite ecstatic about the katana's ability to send out a wave of energy once imbued with cursed energy.

"HAHAHAHAAH, son that was amazing, did you see the destruction it left behind? HAHAHAH."

"Thought you'd be mad..."

"What for?"

"..."

"Anyways, you can get back to what you were doing, you're not in any sort of trouble, just be careful not to do to much damage to the environment next time."

"Well ciao~." Leaving the office of his father, Kakashi went on to train with his sword for 6 days and 6 nights, only taking a break when he reached his absolute limit, and then some.

Huff Huff~

"How long has it been? Feels like I lost my sense of time while training." Said Kakashi in exhaustion. Looking up at the ceiling of the dojo, Kakashi felt a sense of fulfillment deep within his heart. With a smile plastered on his face he went to the dojo's entrance where he saw a plate of food.

The door was sealed so that no one may disturb his closed door cultivation but that didn't mean he was planning to starve, so he left a narrow opening where food may be passed to him.

'Well, that should be enough training, I suppose I should take a bath.' Having smelt the sweat coming off his body, Kakashi made his way to take a shower and wash away all the sweat and grime for the last for days.

Leaving the dojo and heading back to his room, Kakashi entered the shower oblivious to his environment as he was in deep thought. 'The main events of jjk 0 shall be starting in a few years, I plan to go to jujutsu tech with Toge, mostly to see maki tho.' Thought Kakashi with a perverted grin on his face. 'Haven't seen her in a few years. I wonder how she's been.'

Thinking to himself about Maki, who in the original timeline had a hard time, she was currently having a harder time as they were often compared to him and Toge, which unfortunately for him, fueled the Zenin twins hatred for them both, which will make his unrequited feels very hard to express.

'I should do more physical training, though.' Continuing with his inner thoughts, which were futile as his technique alone made him special grade. It didn't take a genius to know that his already immense cursed energy was currently increasing rapidly, having already exceeded Yuta Okkotsu's large reserves, which alone made him special grade.

"Hup, time to get out of the tub." Leaving the warm confines of his bathtub, Kakashi would later go on to become an "official" special grade shaman, at the tender age of 12, which when known by the Elites of jujutsu tech, made them wary and envious towards Akira for breeding such talented heirs.

While simply considered inevitable by Kakashi, he was equally unaware of the trauma of the Zenin twins, which by now quadrupled, thanks to his presence in this world...

AN: Yosh, wassup you lads and lasses, it's your shitty and inconsistent bastard of an author finally publishing another chapter, Hooray!

Well, everyone, I hope you enjoy this chapter, while not long(like my dick.) the plot in the chapter has made great progress without any rush.

Anyway, in the next chapter, we will have a time skip and get to jjk 0 :) So, tuck yourself in for the shit that's about to come.

Btw I'm in Japan rn, and gotta say.... if I wasn't going to be an officer pilot in the British army in the next few months I'd fucking move here, just to stay cooped up in a small ass apartment and watch anime and manga. Well, it is the land of Otaku's. *Shrugs*

Don't forget to drop a review and send me stones...
