A blue marking

BORUTO'S POV 

"ANOTHER LORD SEVENTH?!" I yelled and threw the pack into the air and screamed. Inojin looked at me then sighed and picked up the cards. "Look, you can just give them to Iwabe and Shikadai." He handed me the cards and I accepted them. 

"What was your dad doing to you?" Inojin asked and looked towards dad and squinted like he was trying to read their lips. I stood up and looked back, "I'm not really sure myself." I said and lied through my teeth. I was smart enough to know that it was where my seal was. But why did he want to see my seal? I saw Inojin out of the corner of my eye look at the clock and then run towards Ino.

"MOM! WERE LATE!" He yelled as he grabbed Ino's arm and  began pulling. "Bye Naruto!" Ino yelled being pulled farther away from Naruto. I ran over to dad and handed him some cards "dad can you hand these to Shikamaru to give to Shikadai? I've gotta split!" I yelled and hopped onto the roof and a big grin spread on my face. Me and Mitsuki were going to train tonight. I ran over the roofs until I arrived at Mitsuki's apartment.

I reached my hand out to knock when a snake slithered up my leg and I jumped up startled then saw it was Mitsuki's and sighed in relief as it wrapped around my arm and unlocked the door
The door creaked open and Mitsuki was strapping on his fighting gear. I walked over and placed a hand on his shoulder as the snake slithered up into his sleeve and he turned to smile at me. 

"Are you ready Boruto?" He asked me and I gave him a big thumbs up and we left for the training grounds. We began with throwing our kunai at the tree and then started hand to hand combat. 

"I'm going to use Jutsu." Mitsuki said and I looked at him again.  "Great, then I will do it!" I said getting into a sparing position. 
Mitsuki lunged at me and our Kunai hit each other sending sparks flying off. I ran behind Mitsuki when he jumped into the air and us Snake lightning I ran and saw it behind me and dodged out of the was feeling it grace my back. I rolled in the dirt and got back up. I was out of chakra but I didn't know why. 

We just started sparing! I closed my eyes and the thought quietly and meditated into Karakura's thoughts. "Can I have an extra hand?" I asked and began to feel chakra returning to me and I stood up and felt strong. I pulled my hands together and yelled "SHADOW CLONE JUTSU!" And the clones surrounding me were not 4 but more than 4. It was a large amount; around 100 Mitsuki looked taken back by the amount of clones and used his snakes to make his own clones. Soon enough there was a clone war and me in the middle of them all. Suddenly I felt my chakra depleting and fell to my knees as a clone of Mitsuki's attacked me from behind, digging a kunai into my back, making me scream out in pain. I fell forward as another used Wind scythe jutsu. I stared in horror as I got myself into a sitting position bracing for impact holding my hands in front of my body when I heard all the fighting stop. I opened one of my eyes to look around and see what happened. Mitsuki stood there staring at me like I had done something unheard oh or like Karakura had… "Karakura! DID YOU DO SOMETHING?!" I yelled at the top of my lungs and then was met by his reply. "No!" He replied he sounded scared. "That was all you Ona-San!" Karakura yelled and then I sighed and looked at Mitsuki as he looked interested in what had happened. "What happened?" I asked as he pointed towards my arm and said nothing. I lifted my arm to my face and saw a black mark had spread across it and was a bright blue.
