Black blade

with Kakashi opening his eye and making Chidori,Asuma was also ready

Asuma way of fighting is with a dagger and he strengthened his dagger with chakra

He knew Kakashi might able to dodge him after Sharingan so he used Wind nature of change along with soru and increased his speed again given the name "Sunpo " by Shikai

with sunpo and dagger , Again the fight between Kakashi and Asuma started,

Asuma with Sunpo was faster than before so ,Kakashi could only react at the last moment and Kakashi's attack was also heavier and lethal than previous but they were parried by the dagger of Asuma and using Sunpo he again gets his prefered distance.

this play lasted for 15 minutes as both have their own limitation,they were not like Guy who has speed and power so, the play between then were a stalemate

hence both decided to have a direct attack and both were ready even for a serious injury

Asuma also now powered up all his chakra to the feet and Dagger, whereas Kakashi strained his eye and Chidori

the both came straight,

Asuma soon reached Kakashi side and attacked with the dagger but Kakashi with Sharingan shifted his body and attacked with Chidori

looking at the position of their attack , they both knew that today they might lose a goddam amount of blood but even knowing this they can't stop now because they don't have the power too

so just as they accepted their fate, Shikai used both soru and Shadow speed at once giving a boom of speed , he reached between them , held both their hand and directly threw them to opposite direction ,

this was the same way how Kakashi stopped Naruto and Sasuke

Kakashi flew toward the rock fully disintegrating it, meanwhile Asuma also destroyed a whole tree

the power level of the attack was the same

after cooling down Kakashi apologize to Asuma Asuma was stunned hearing Kakashi apologize but they were a friend for a long time so the matter was solved

Shikai " so do you want to have a go with me Kakashi sensei?"

Kakashi" umm,i still want to return a punch "

Asuma" well seeing the speed of Shikai , you wont be able to match him so i will fight along with you against shikai""hope you won't mind Shikai"

shikai" no problem"

with this, the match started but before Kakashi and Asuma were ready they were already thrown in the air with a kick and punch in their chest"

just now they realized that Shikai had already stepped the power level above them, The level of elite.

With this fight Kakashi finally learned that he had been arrogant and not developed in a decade, And Asuma knew that his student had won against him but both now want to be stronger which was good

after this match Shikai went home leaving ,Asuma,Kakashi and Guy alone where Kakashi asked about soru to Asuma and Asuma asked about how to make his Attack lethal , both gained a lot this time

After 1 year of Naruto departure , Shikai finally made his decision and attacked s -level missing ninja named Dabura , who was a mid-level kage level from the Stone Village ,

this was the hardest battle in the life of Shikai

he an elite jounin fought with Mid-level kage expert

Dabura was an amazing character who was a missing-nin after he stole the secret technique of heaviness and lightness

he reached an amazing level with a heaviness that his one punch carries the power of a 100 m high mountain

This fight was the comparison of their experience ,Dabura who was a missing nin from Stone village and Shikai who had a daily life and death match with two kage soldier

so the fight was a long one as Shikai chakra blade couldn't harm the body of Dabura and Dabura heavy attack won't hit the target

Dabura now decided to use earth wall and trap Shikai

finally, he managed to trap Shikai in an earth dome and had a relief breath

When shikai was trapped in the dome he thought to call his puppet but gave up the idea and thought hard

inside the dome, it was black meaning the whole inside the dome was shadow's

seeing this Shikai lit the best idea, that is to make his attack power lethal that it can fully destroy the dome and harm dabura

so he quickly surrounded his sword with chakra and again covered with the shadow giving it a black color Shikai knew this method from one piece so this was his version of 'HAKI"

after this process, he just did a simple swing which cut the dome exactly where he needed and he finally came out

Just as he came out he saw ,Dabura was now ready to leave thinking shikai was trapped

Shikai shouted"hey take this attack and flashed"

Dabura hearing the voice turned around guarding his chest but how could that help against Shikai who had just made progress so dabura was cut through,dabura knew he will die so he asked"what was that attack"

Shikai replied "Black blade" as he didn't want to say haki because it was not a real haki

after Dabura died He asked nightwalker to bring this head to the stone village to get money and extracted the shadow

after the shadow extraction, Shikai finally manage to reach the power level of 12 which was the peak of low-level kage, now he can fight pain but can't win

The time before naruto return 1 year and XX days

with the shadow being extracted,he used the shadow of Dabura to strength "Gratos" which was the strength type

finally "Gratos "reached mid kage in power but "nightwalker" was just low level,. so he sends both Gratos and nightwalker to Stone village to not have any loss

Shikai-12 level-15 power level

Madara, Senju-20 level

Tentail-26 level

Kaguya=30
