This is going to be about Kazuma and Kazumi depicted as Sasuke and Itachi respectively.
Let's admit it,Kazuma is basically Sasuke in Vanguard.
If you are interested,I referenced it from episode 139 and 141 of Naruto Shippuden
Kazuma was lying on a soft mattress as he slowly begins to wake up.He finds himself not in the same position that he was in when he was fighting his brother Kazumi.He slowly got up,trying to piece back his memories together of what had happened earlier.
Did he really kill his brother Kazumi?
Did he really finally rid of the nightmare that was taunting him these few years?
Kazuma couldn't believe that he had finally put an end to his brother's evil deeds.Now he no longer has to worry about it anymore.
"I see you've finally awaken."
Kazuma turns around to see a black-haired man with hair all the way down to his back.But he was in a mask so no one could tell who he was.
"I've brought you here to talk to you about something."Kazuma was still stunned about the fight with Kazumi that he didn't really cared about what the masked man was going to talk about.
"It doesn't seem like you're interested.Maybe if I phrase it a little differently,you'll just might be able to listen.It's about Kazumi uchiha.You claim to know everything about your brother,but you know nothing at all."Kazuma shifts his eyes a little to look at the masked man.
"Seems like I've your attention now.How about I introduce myself first."The man then shifts his mask a little to his left to show an eye,the eye that only Kazuma's clan have.It was the sharingan.
"Like you,I am the sole survivor of the massacre,and the one other person who knows the whole truth about Kazumi."
Kazuma suddenly felt his sharingan activating without his knowledge and that started to burn the masked man with a familiar black flame.Kazuma felt breathless after using it and his sharingan began to deactivate.
"Wbat was that just now?"Kazuma,who was still feeling pain in his left eye,questioning himself.
The man soon recovered from the said flames without any injures.A feat unknown how he was able to do it.
"It was the Amaterasu that Kazumi implanted in you."The masked man replied.Kazuma was then shocked at what he had heard.
"Typical Kazumi.Even after he's dead,he still surprises you to no end.He even took measures for this occasion."The masked man commented.
"What are you talking about?"Kazuma asked.
"He transferred that technique into you in order to kill me.No actually,to put it simply,it was to keep me away from you.I'm guessing he set it up so that once you saw my sharingan,you'd activate Amaterasu like a trigger."The masked man replied."Although Kazumi never knew everything about me.If he did,I would no doubt be dead already."
"So tell me what is this all about?"Kazuma questioned the man.
"Before his death,Kazumi must have done something to you,didn't he?"Kazuma the recollects about the the battlr against his brother as he was poked in the forehead by his brother.
"Within his final moments,he transferred all of his oculur powers into you."The masked man commented.
"What do you mean by that?Why would someone like Kazumi do that for me?"Kazuma continued to question.
"Don't you get it?"Kazuma then looks at the masked man in the face,"He did it...in order to protect you."
Kazuma was stunned by the information the masked man gave him.He can't believe that someone like Kazumi would do such a thing for him.
