Chapter 5: The Mangekyo Sharingan
Several years past and the Uchiha brothers were now in their early teens. The war had neither progressed nor eased. When the Uchiha won one battle, the Senju would win the next - it was mass slaughter. The brothers sparred every other day when they were not fighting. While honing their battle skills, they simultaneously matured their Sharingan to three tomoe.
The brothers returned from battle after another long day of combat. They unclipped their armour and set it inside of the front door. Madara wordlessly left to fetch a pale of water and some rags, while Izuna sat exhausted on the step that separated the front entrance from the rest of the house.
It was the same ordeal day in and day out. Fight all day, if you survived, return home clean your gear of muck and blood so it wouldn't rust; sharpen and resupply you utilities, then go out to fight again the next day.
Madara returned with the rag and casually threw it over to his brother who caught it effortlessly,
"Thanks." Izuna sighed as he began wiping down his armour. "We haven't become any stronger lately no matter how hard we have trained Madara."
"I have noticed that too," Madara replied wiping a large blood stain on the back of his armour.
"So I have been thinking, we may need to cut another tie again." The stain was persistent, so he scrubbed harder.
"Hmm, like when we first awakened the Sharingan, brother?" The younger Uchiha perked up a bit, not only did Madara agree, but he had already been manifesting a plan.
"Yes, although we may even have to sacrifice something greater than before." The stain finally cleared and his older brother moved on to check the rest of the suit.
"Like killing a friend, rather than cutting ties?" Izuna finished his armour quicker than usual and set that aside to wipe down his katana.
"Afraid so…"
"We can do this brother, we have to." The younger brother replied optimistically, whereas Madara still had a hint of hesitation in his voice.
"Are you sure Izuna?"
"I am, I already know who I want to kill." The younger picked up his grinding stone and sharpened his blade.
"…" The older Uchiha had finished his armour and took a moment to set it down against the wall and gather his thoughts. He hadn't thought any further ahead on the matter. Besides, he would always see Izuna as his younger brother in need of protection. Hearing him eager to murder his best friend for their sake of greater power, reminded Madara of just how much Izuna had matured in the past couple of years. "The first night raid will commence in a few nights, we will do it then."
"Does that mean you have no intention of participating in the raid big brother?"
"I don't, we must guarantee our survival." Madara shifted to sit closer and held his hand up to hold his brother's cheek.
They were currently approaching the cooler months of winter and the days were becoming shorter while the nights were stretching longer. Battles were fought on into the darker hue of the night which was useful for the Uchiha brothers. The friendly fire could be blamed miss-identification of an enemy and night raids upon other villages were also increasingly common. The combination was perfect for the Uchiha brothers to carry out their plan without any suspicion from the other Uchiha.
"The raid will be against the Hoki clan, we have claims they stole a scroll containing valuable intel of our clan's strategies! We can't let that intel be disclosed to our enemies! You are to form groups of four and each team spread around the Hoki clan's settlement. We will strike from all sides at once! Do you hear me, brothers?!" A relatively young Uchiha called out from the upon a wide granite rock the Uchiha used as a stage. The man's name was Rai Uchiha and he had taken over Taijima's role of the Head of the Uchiha. He was chosen as one of the few members who had awakened the sharingan as a youth and still had the will to lead the clan into battle.
"Yeah!" The crowd of Uchiha roared in unison before dispersing into groups.
"I'll get my friend," Izuna mentioned to his brother and disappeared into the crowd. Madara had found his friend Fugi, before the meeting had started, so they waited for Izuna to return. Fugi
Uchiha was a slightly older individual with short sandy hair that stood straight up, defying gravity.
"Izuna? You want me to team up with you when we haven't spoken for years?" Kurowa exclaimed.
"Yeah I apologise for my behaviour, now will you come with me or not?"
"I guess it wouldn't hurt. But what's gotten into you?"
"… I'll tell you if you survive the raid."
"Heh… you're as stubborn as ever Izu… You got a deal, I'll join you."
Madara perked up when he saw his younger brother return through the now groups of Uchiha. "Good you're back, let's go."
The team of four jumped the branches on the way to the Hoki clan's supposed location. The trees gradually thinned out and were replaced by a bamboo forest, territory known to the Hoki clan.
"It should be just up ahead, we should stop here," Fugi explained. Their group stopped by a boulder to rest and plan their next move.
"I'll go on and scout just ahead," Kurowa suggested and jumped off to climb a sturdy bamboo tree.
"Now Izu," Madara whispered to his brother.
"Huh?" Fugi went to question his friend but was met with a stiffened palm to the neck. "Ugh!" A few more blows from Madara left his friend beaten to death.
The cries were short-lived as the young man fell heavily chest first onto a pointed boulder.
"Y-you t-traitors!" Fugi stuttered in his last breath, his head rolling to one side.
Swoo, swoo, swoo!
Izuna released a rain of kunai on his unsuspecting friend dead in their back.
"Wha-? Ugh!"
Kurowa was less fortunate and had died instantly upon impact.
'It was rude of me I never told you the truth. But you did me two favours Kurowa. Be thankful you are no longer suffering in this world.' Izuna walked over to his older sibling, wearing a smug smile on his face. The tomoe of his illuminated Sharingan swirled around on his iris, merging and changing shape. When they stopped swirling, his tomoe had taken the shape of three blocks extending from the inner circle to the outer iris.
"Success brother."
Madara looked over to where he heard Kurowa's final cry. He was standing cockily with his thumbs wedged in the cloth tied around his waist like the feat had been mere child's play instead of cold-blooded murder.
"Indeed it was." The older brother's eyes had also evolved. His tomoe had now connected to each head to tail and formed a hollow in the head region. "Now we'll wait it out until the raid is over and head back with the rest of the Uchiha. It would be suspicious if they found we returned early," the older Uchiha continued.
The brothers found another clearing away from the murder scene in the bamboo forest to sit and wait.
"You got a little more excited than expected I see?" Madara commented noticing a slight rise in his brother's pants.
"It felt good this time, evolving our Sharingan. We are the first in Uchiha history to achieve this far! I can't wait to show the rest of the clan, we could over-throw Rai as clan leader!"
"Now that would be something to be proud of," Madara added, shifting to reach over to his brother.
"However that is issue for later, right now we have a more urgent matter to deal with."
Izuna's sly smile was quickly accompanied by a hot blush on his cheeks. He leant back against the bamboo shoot and spread his knees a fraction to allow his older brother more room. The unusual intimacy between the brothers had grown from always sticking together in their day to say lives; rarely separated for long. They even slept in the same room on their own beds in fear one would disappear during the night without the other knowing. Even when their sex drives had started to awaken during the past couple of years, they had little opportunity to hide it from each other. So they mutually agreed they wouldn't hide it since they couldn't.
"Ah, your hand is cold Madara!" Izuna whined.
"Sorry about that, give me a moment to warm up." The older Uchiha palmed his brother to allow more contact and friction from his hand.
"Nngh…" The younger Uchiha closed his eyes as his older brother's hand heated up and felt more pleasurable on him. Madara took that as a signal to continue properly and changed his grasp to stroke Izuna. "Ha, brother!" The younger sibling clenched his eyelids tighter and threw his head back against the bamboo. He was leaking now. Madara coated his fingers in his brother's slick and worked on him further into bliss. "Ha- ha- ha- Mada- I'm close."
The older brother formed his own sly smile as he finished his brother off. Izuna panted in the aftermath. "T-that was better than when I do it myself…"
"Che, course it was. I have seen how you do yourself." Madara wiped his hand as clean as he could for now on his own clothes.
"Heh, just because you're a year older than me that gives you so much more experience." Izuna chuckled sarcastically. "Next time you get off, it is my turn to give you a shot."
"Sounds fine to me."
The brothers returned home along with the rest of the Uchiha military, with the Uchiha scroll successfully reclaimed. As planned, no one noticed their absence in the raid or questioned the lie too long on the loss the fallen group members.
"My brother and I also have something more important to share," Madara stated, standing on the rock stage.
"We're listening," Rai replied bitterly, annoyed someone of lower rank was standing on 'his' podium.
"We have managed to evolve our Sharingan further than even known to the Uchiha clan," Madara announced. He and Izuna activated their Sharingan to reveal their personalised tomoe patterns.
"We call it the 'Mangekyo Sharingan'," the younger brother added.
"Woah." A harmonic of voices sounded, followed by murmuring among the clan.
"Madara and Izuna, our new leaders!" Someone called above the discussions.
"Hey wait!" Rai rebutted but was ignored.
"Yeah!" the men cheered.
"Yeah! Our new leaders!"
"Hn." Good, this is going better than I anticipated. Madara thought.
