Prologue :

Ryuujin Senju woke up suddenly, after a bad dream, "Why do i have this dream always, Its too scary, thank God it was just a dream" He dreamt of a time, where the senju clan died, by the hands of Madara Uchiha, in a few years, but that can't be right, can it?

BOOM

[SONG NAME- VOGEL IM KAFIG]

"Oh. The senju are really dying down huh?, Why not accelerate it?" said Madara. Ryuujin felt fear for the first time, at this magnitude. He has been scared, but to be seeing Madara, the only one who could possibly beat their creator, Hashirama Senju. He knew he had to act quickly, giving his one month old son to the Hokage, Kai senju.

"Oh look at here! My friends grandson, Wouldn't it be ironic, To kill his grandson, After all he "killed" me," said Madara sadisticaly "And there is his son too! I might just leave him alive, after all, He seems to understand true power." noticing Kai crying.

"You may take our clan, our lives, but I will not allow you to take my SON!" Screamed Ryuujin, his love for his son destroyed his fear. "Looks like I need to remind someone, Why i was Hashirama's rival," Said Madara

SPLASH

Blood can be seen on the floor, The blood of Ryuujin. Kai seemed to realize this, and started bawling heavily
"Shit, My time's almost up, I have to go. I have t-" As he said it, Madara disappeared. But his mask was left behind

Next day

"Hello Ryuujin are you here?" Asked the yondaime Hokage, Knocking the door

No reply

"Hello?" The Hokage said, Knocking a Little harder,

No reply, but a faint crying can be heard.

The Hokage busted in, and only saw bodies, with only one child remaining, the child of his friend, Kai Senju.

"What the Hell happened here?!" Exclaimed the Hokage, though he had a distant feeling on what might have happened. He noticed A orange mask, Wit a spiral opening to one eye. He thought about all the people how could and would want to destroy the Senju clan, Many answers came for the second question in his mind, but only one came to his mind for the first question. Madara Uchiha. But that wasn't possible. He was dead right? Didn't Hashirama kill him?

He decided he would worry about that later, First he had to search for the crying sound, most likely being Kai, Ryuujin's son

After searching for a while, he found Kai, sleeping peacefully, As though nothing happened. Minato took him and went to his own house

"Kushina, I have bad news." Said Minato

"What is it, Too much paperwork?" said Kushina, laughing

"Kushina, it's serious" Said Minato, in a cold voice

"Why do you have ryuujin's son?" Asked Kushina worriedly, after seeing Minato holding Ryuujin's son. "Did something happen?"

"The entire Senju clan was mascaraed. Only he was left behind." Said Minato, worry could be heard from his usually calm voice.

"WHAT? How? There is no one who could defeat them! exclaimed Kushina

"I don't know. All we need to know is there is a person out there who could kill a whole clan, the strongest nonetheless. We need to put the mask on the bingo book immediately, as the masked man could as well as be Madara." Said Minato "I know he died, but I can't think of anyone else who could take out the whole senju clan." He said before Kushina could speak

"We should also keep his identity secret, We can tell him, but we HAVE to have some anbu or jounin company him AT ALL TIMES, To make sure he doesn't say it, or he, in case the word goes out, is protected"

"I really hope something like this doesn't happen"

[The next day]

"Hokage-sama, could you please tell us why did you call for a emergency meeting?" Asked one of the members of the civilian council.

"Wait for some time. We need everyone here." Minato said

A few minutes passed, and the third Hokage came

"What is it Minato, what situation is so dire - " said the Third Hokage, When he saw that the senju seat was empty. "What happened to Ryuujin?", asked the Hokage, almost demanding.

"Please sit Sarutobi-sama, I will explain everything once we start." Said the Hokage, almost annoyed

Once everyone came, The Hokage said " This emergency meeting has now started. No onto the news directly, no need of formalities. The senju clan was mascaraed last night, almost today midnight if you might say."

Chaos erupted, Everyone from the civilian side started shouting, until Minato raised his KI.

"The situation is already out of hand. I don't want anymore chaos" ordered Minato "Now I have to discus what we have to do with the shinobi council."

"Were there any survivors?" asked one of the civilians

Minato hesitated, he knew it would be villainous of him to deny Kai's heritage, but to protect him, he would have to keep his identity as a secret.

"The last remaining Senju, is Senju Tsunade, Who has left the village a some years ago." said Minato, convincing them

Once the civilians went, He also ordered the advisors and the clan heads to go out, leaving only the third Hokage, Sarutobi Hiruzen, The head of intelligence, Inoichi yamanaka and the head of the military forces, Shikaku Nara.

"I lied" said Minato "There was one survivor, Ryuujin's son. But i had to protect him, he could be in danger, being the last of the greatest clan of all time."

"You did the right thing, His safety is very important, Not only for a personal reason, But for the village too. Tsunade is as good as a nukenin at this point, so he needs to be protected. especially from my teammate, Danzo" said the third Hokage.

"We could tell him later, in a calm environment and explain why before telling the secret, once he is old enough." Said Shikaku

"I, as the head of the Yamanaka clan, will always support him discreetly." said Inoichi

"I would rank it higher, but there is no higher rank, hence I make this a S ranked secret. If i even hear someone suspect him being a senju, unless he does outright show Mokuton to someone accidently, which is unlikely, I will order your execution publicly" Said Minato, in a commanding voice.

The rest just nodded


A/N: Sorry this isn't an update, but i felt it was important. Please leave a review, and give constructive criticism. This is my first story so wish me luck

Now onto Kai. Yes this is an OC, but this OC is based of me, (not the past, but his behavior and potentials). It is going to be a third person pov. Hopefully because he is basically me with a more tragic backstory, i might write him better. He is going to be pretty strong for his age, probably around Mid chunnin without his bloodline (with his bloodline he might be mid jounin, and no its not a stretch, because his Bloodline is OP, but difficult to master.) . So expect the occasional curb stomp, but not frequent. Please suggest another name for Him, I just used a random name.

His potentials now. He is going to have the highest potential in fuinjutsu, since I am pretty good in logic. His next is going to be ninjutsu, since he is a Senju, (without his bloodline. With it, that's going to be highest). He will be decent in genjutsu since he will have surprisingly high control for having large chakra reserves ( he will have large enough to create 100 kage bunshins. What did you expect? Senju are Broken) Finally taijutsu, He isn't going to be too weak in it, but if you want to defeat him in a field, it would be here. His hits would be slow but strong; eventually he will get faster. He will also learn Medical ninjutsu, but it is not going to be his focus. And he is mainly

He is going to be extroverted, so be ready for interactions between him and Naruto
