Nishimura and Yuki left first to get the enemies attention and a while later, both Akio and Ryota left with the clones.
In the grassy plains...
"Sensei, five are on our tail!" Yuki informed as Nishimura nodded his head and took out his kunai.
Yuki too took out his kunai and grabbed it tightly he had a bad premonition.
"YUKI GET DOWN!!" Shouted Nishimura as he lied on the ground, Yuki immediately followed suit.
Ten kunai went through them at an extremely fast speed "F.u.c.k these are anbu!" Complained Nishimura as Yuki realised how he almost died.
Since they stopped, the Iwa anbu got to them and surrounded the teacher and student. Nishimura spoke to Yuki "Go all out!" And charged at the anbu.
Yuki grabbed his kunai and deflected a sword slash from one anbu and kicked him.
*flashback*
Yuki thought in his head "I'm no longer Charles, I'm Uchiha Yuki and for me to survive in this world I have to be strong! Pure strength is useless in this world...what I need is speed, speed to quickly finish my opponent!"
He used his chakra to boost his speed, while thinking "if too much chakra can break the bark can't I do the same with earth?"
He put more and more chakra into his feet that the floor exploded throwing him away.
"This is it!" He thought and tried again and again.
*flashback end*
He kicked the Iwa anbu with the same amount of chakra, "gah!" The anbu grunted as the kicked area exploded spilling his guts instantly killing him.
The other anbu who saw this were enraged and attacked more aggressively.
Yuki activated his sharingan and dodged one anbu and slide behind him, when the anbu turned around Yuki slit his jugular vein, stuck a explosive tag on his sole secretly and kicked him to the second anbu.
"Sensei, take cover!" Shouted Yuki and shushined with him.
The second anbu saw that his teammate was dying and ordered the retreat but was too late as the tag exploded on the four of them.
One female anbu jumped back but was too late and suffered heavy injuries on her legs.
"Ahhh!!" She screamed in pain while staring at her legs.
Yuki stuck a explosive tag on her c.h.e.s.t and left while she looked at him with a smile and exploded immediately easing her pain.
Yuki then realised what he had done "what the hell am I doing?! I killed people! Fifteen people!" He fell on his knees and grabbed his c.h.e.s.t contemplating.
Nishimura saw this scene and remembered his first time killing someone. "Yuki do you feel bad killing them?" He asked, "yes!" Yuki replied "don't be" he said casually "how can you say it so easily?!" Yuki asked "because I went through the same thing and my friends died for it!" He said.
Yuki wanted to retort but heard the last part "This is the cruelty of this world... kill or be killed" he realised "hehe no wonder Madara went crazy..." he finally rearranged his thoughts and looked at his sensei and said "thank you". Nishimura smiled "It's not wrong to feel bad! It shows that you still have a heart" he said and muttered under his breath "unlike me...".
In a forest...
Ryota and clone Nishimura were hopping from branch to branch.
"Ryota, there are two following us!" Warned the clone.
"Alright sensei!" He said and stuck an explosive tag on the branch he was standing on and hopped away.
Luckily the two Iwa shinobi were jonin and just promoted, one of them stepped on the tag and exploded. His leg was blown into smithereens as he fell down dead.
The other one took out a kunai and charged at Ryota who also took out his kunai.
The two shinobi were fighting each other for supremacy, both trying to break the enemy's defence.
Ryota lost due to his inexperience and slipped, he quickly back flipped and dodged the slash but was still injured. The clone jumped at the jonin and kicked his knee cap popping it, the Iwa jonin screamed and fell off the branch and when he was falling Ryota threw a kunai at his throat killing the jonin pinning him to the ground.
"Ryota, meet the original at the waterfall we saw on our way back!" Said the clone and dispersed. Ryota left immediately after taking his kunai back.
Akio sensed four jonin level chakra signatures following him and Yuki's clone.
"Yuki, four jonins!" He warned the clone who nodded. Yuki took out a kunai and turned around to see multiple shuriken on their way.
"Shit!" He cursed and pushed Akio away and started deflecting the incoming projectiles, the four Iwa jonins spread out and attacked Yuki immediately.
"Akio RUN!" shouted the clone as he fought against the four jonins.
Akio looked back and ran away, Yuki who was defending let one jonin slip through him and gave the other three an opening who used it and distracted Yuki, "f.u.c.k!" He shouted and stepped on the leg of one jonin really hard and chakra reinforced, his foot was smashed to paste as he he screamed and let Yuki slit his throat.
The other two were surprised but concentrated on Yuki who later kicked both jonin in the face really fast and threw few shurikens at them. One of them died while the other was heavily injured but Yuki had to go fast to help Akio who was up against an experienced jonin.
*boom*
Clone Yuki saw black smoke in the distance "Akio!" He thought and ran faster.
In the distance, the real Yuki and Nishimura were looking at the black smoke and prayed for both Ryota and Akio.
"Akio!" He shouted and rushed to him while glaring at the Iwa jonin.
The Iwa jonin stared at Yuki for a while and laughed "like mother like son!" He commented as Yuki froze on the spot.
"Haha what happended little brat? Do you miss your mom?" He shouted at Yuki "too bad cause I killed her, why? Because that bitch killed my brother!" He continued.
"Akio just don't die, you remember the motto right?" Cried Clone Yuki as he took out a bandage from Akio's pouch and wrapped it around his bleeding arm.
"Yuki...I don't...think...I'm...gonna make it..." coughed up Akio who was losing blood really fast. Yuki grit his teeth and glared at the Iwa jonin.
"Hehe That's the look she made when she was surrounded!" He taunted.
"You bastard!" The clone shouted and charged at him with a kunai. Within seconds Yuki was right infront of the Iwa jonin, he flared his sharingan and slashed the kunai deflecting the strikes of his opponent.
Yuki slashed the kunai horizontally when he saw suddenly predicted that the Iwa jonin was going to kick him. He sidestepped and dodged it while stabbing the kunai downwards at his knee.
"AAAHH!!" the jonin shouted in agony, he had torn his ligaments and tendons due to the sudden and accidental split he had just done. Yuki thrust the kunai at his heart and rushed back to Akio.
"Ahhhh!!" Yuki clone cried as he hugged the dead body of his friend, he felt his eyes burn but he didn't care, he only wanted to mourn for Akio.
A few minutes later, clone Yuki was sniffling as he stored Akio's dead body in a scroll and left the area.
At dawn, the next day...
At the waterfall, Nishimura and Akio were hiding in the trees looking for their teammates.
Ryota arrived first with Nishimura clone as they gathered up for the next step of the mission. A while later a haggard Yuki clone came and handed over a scroll and vanished.
The moment he vanished, Yuki fell on his knees and grit his teeth, his tears falling freely. He opened the scroll with shaking hands and applied chakra, white smoke blew up and the cold body of Akio emerged.
Ryota wailed as Nishimura sighed, the latter sent a message back to Konoha about the mishaps and summoned a bird to take it away. He let his students take a break from all the shit and went ahead to check the surroundings.
Yuki sighed and got up to wash his face from the waterfall, when he stared at his reflection he found that his sharingan had morphed into an intricate pattern.
It was the same red sclera but the pupil had changed into a diamond(the card type) shaped pattern but it was square shaped(all sides equal).
He deactivated it at continued what he was doing. He went to Ryota and pat his shoulder "Yuki" Ryota said hoarsely "Ryota, don't cry! We have to continue the mission for Akio so that he didn't die in vain!" Declared Yuki "besides... he wouldn't want us to be crying all the time right?" He said as he smirked and went away.
Ryota then smiled remembering Akio and his antics and clenched his fists determinedly and he too went to wash his face.
Nishimura got up "about time!" He thought and walked up to his students and gave them the detailed plan.
"got it?" he asked as the duo nodded and they shushined to the trees...
