Boruto Otsutsuki (Concept belongs to MiniNejiOwO?

How it started

Naruto POV

I was taken hostage by Momoshiki. They were draining my chakra and then the stopped. Boruto, Sasuke and the other kage jumped out of a portal.

"Tou-Chan!" Boruto yelled while geting me out of the ropes.

"Boruto..."  I said.

"It's ok Tou-Chan!" Boruto said then looked at me.

"How about instead of giving me a lecture next time tell me about you past." Boruto said.

"Ok, but I should warn you it's really long." I replied back.

Time skip to when Boruto uses the Uzumaki rasengan.

Momoshiki is about to die but eats a chakra fruit pill.

"Naruto!" Sasuke said looking at me.

"What's wrong?" I asked Sasuke.

"This isn't working, we will have to seal him in sombody..." Sasuke said words full of guilt.

"But that mean he will be sealed in..." I was cut of by Sasuke saying "I know.." Sasuke said, refocusing his attention on Momoshiki.

"What are you guys mumbling about?" Boruto said looking at me and Sasuke.

Boruto POV

"It's nothing " Tou-chan said looking away. His face looked scared and guilty.

"You sure?" I replied eyeing my dad's and Master's faces.

My dad looked at me and two words escaped his lips. "Sorry, Boruto." My dad lunged at me and performed a sealing jutsu. That was all I knew before I blacked out.

Naruto POV ( In this au Naruto is strong enough to survive the seal his parents placed on him.)

I held my son in my arms and tears escaped my eyes. I hated what we had to do... I didn't want anyone else to experience the pain I did, now my son has to...If I had been stronger this wouldn't have happened.

Sauske put a hand on my back then opened the portal.

We walked out of the portal and into Konoha. Hinata ran toward me and gasped. "What happened to Boruto?"
She looked at me as a tear escaped my eye.

"It's a long story.." I said looking at her. "Please get all the parents of Boruto's friends to my office" I ordered.

In the hokage's office (RN Boruto Is in the hospital)

"You might be wondering why I called you here..." I said

"Yeah!" Sakura said looking curious

"What happened to Boruto?" Sai said.

"Yeah!" Ino said she looked mad.

"That's what I'm trying to talk to you about." I said.

"We couldn't defeat Momoshiki..." everyone looked up, "I had to.." I couldn't finish.

Sasuke looked at me then said " We had to seal Momoshiki in Boruto."

Hinta teared up. "WHAT?!" Everyone asked, "I'm sorry..." They looked at me. 

"What if he loses control?" Asked Ino

"If that were to happen, we would place paper seal to put him back in check. Just like y'all used to do for me." I said and then reached into my drawer and pulled out paper seals for everyone. I handed 3 to each of them.

"I should go check on Boruto." Sakura said as she turned to leave. "Were coming to!" I heard hinata say referring to me and her.

(Time skip they are in borutos hospital room)

'Does he want to see me?' I thought.
I entered his room to see him hooked into a oxygen mask to breath. He gained so much chakra in a second his body went into shock.

(Borutos Pov)

"Where am I?" I said as i woke up in a room that the floor was water.

"Finally human child.." I heard a voice say. I stood up and saw Momoshiki standing there.

"Momoshiki? I thought you died!" I exclaimed as he looked at me.

"They couldn't kill me so the sealed me inside of you..."

"What? How?" I looked at him as he explained.

"It's like I'm your
Kyubi and your my jinchurikii." He said

"Isn't dad a jinchurikii?" I said

Momkshiki nodded. "You are going to wake up soon." Momoshiki said.

"Wha-"

My eyes blinked open as I saw Tou-Chan standing over me.

Tou-Chan?" I asked still waking up.

"Boruto!" Tou-Chan exclaimed.
