Your P.O.V
The two legendary sanin went towards our team and Tsunade smile and said "(Y/N) I sense you have a power type of chakra inside you, you can use it to protect your comrades or leave it uncontrolled, and Rin, I sensed you wanted to learn medical jutsu to be able to be useful to everyone. If you girls agree to go, class will start every Saturday and Sunday and it will be personal training for you 2" Rin and I hugged and squealed. The 3 man were staring at us in amusement. I then felt a little bit of sadness...the Crimson Avenger was inside me and I don't think I can control it..."Sensei does she know my secret?" I asked and Minato nodded. I looked down and Minato said "don't worry, when the time comes you can confess" he placed his hand on my shoulder and I heard an announcement "okay folks if you really want one more show here goes!" I was shocked, no one told me about having to concert. I heard everyone screaming out my name so I went outside you the microphone in my hands the song that I sung when I was trying out started.
I wish to numb my heart, to numb my heart
Against the pain and take it away
Because there could be more than this
Those countless times I gave up all hope
Because I couldn't change what's behind me
I hid inside my shell from the world
Out of sight, tucked away so no one could see me
Once again I feel the pain rise inside
Rushing back to me like an unstoppable tide
I don't need the warmth, and no, I don't need the pain
I'm fine without this thing called "love"
I wish to numb my heart, to numb my heart
Against the pain and take it away
So I can overcome the dark
Just like a shooting star in the sky
Into the deep, I sink, nearing the brink
My heart and soul succumb to fall
I try to scream but there's no sound
So I accept I won't be found
But then I hear your voice calling
I'm no longer falling but rising up
As you pull me into the light
The world I knew, once quite and gray
Began to change when you looked my way
I thought sure my heart wouldn't heal
But I guess, you have made the impossible real
Look me in the eyes and make my heart skip a beat
Fill my world with my world with colour and set my spirit free
I was never falling- I was swept of my feet
The very moment you reached me
I wish to numb my heart, to numb my heart
And find the strength to heal what's inside
So I can overcome the dark
Just like a shooting star in the sky
Into the deep, I sink, nearing the brink
But now I know you're there if I fall
I'll show the darkness I can fight
When I'm lost, you'll be my light
So now there's no hesitating
I'm tried of wanting to turn the page
And to find out what's to come
I always treasure our time together, these golden memories
When I was falling and you were calling. I heard a knock on the door
Through all the pain I've overcome
I'll step out of the shell
I've waited all this time to turn the page
And now, I'll finally blink away what held me in the past, I swear!
I wish to numb my heart, to numb my heart
Against the pain and take it away
So I can overcome the dark
Just like a shooting star in the sky
The oath will never die, my tears have dried
I never let my life slip on by
Because I know I have more than this
And if I had only one wish
I pray the chapters the follows will lead to tomorrow
So I will see what the future holds for me
Everyone cheered again and I went inside exhausted "I don't want to continue anymore, I want a mission where we could fight and stuff" I said and Kakashi said "As if you could fight" I replied in a angry voice "what if I could?! you only care about rules!" I crossed my arms and looked away.
~Time Skip~ Saturday
Rin and I went to Tsuande office and taught Rin and I medical jutsu but what made us more surprised was when she said I have enough chakra do use immense strength using little chakra. Tsuande taught me it and after 5 weeks I was able to use medical jutsu and immense strength and Rin was also able to use medical jutsu.
"You're so cool now (Y/N) you can easily fight with using a lot of chakra, you even now how to summon toads, Jiraiya had a special training with you too and even taught you sage mode! I wouldn't even be surprised if you were able to become the first female hokage" Rin exclaimed. I went over to Minato and our team. "Apparently our mission is to fight 3 dangerous shinobi that is coming to kill our current hokage, so we must kill them before the kill one of our leader. I want all of you to work together to bring them down" We all nodded and started packing up everyone was wearing their shonobi outfit and I was wearing the Crimson Avenger one "what's up with that outfit and sword" Kakashi said but you ignore him "now now Kakashi (Y/N) has permission to where that for a specific reason. "
We all started running until we finally hit on of the three ninjas and apparently, he was very weak and the second ninja was better but not as good. We thought this mission would be easy but the third one was even more powerful then our strength combined. I made an earthquake hopping that he would fall in it, but he didn't he ran over and attacked Minato, we all went and strike but he was able to dodge it "the leaf village are the weakest village, especially them 2" he said pointing at Rin and I "I suppose I'll kill you 2 first" he said and ran for us. Rin and I tried to get up but we were too exhausted, I tried to turn into sage mode but I didn't have enough time, suddenly he started moving and grabbed a sword from his back and stabbed Rin, I stared in horror as he started laughing like a crazy person, he then went over to Kakashi with his attempt to kill Kakashi but Kakashi started fighting, I carefully took the sword out of Rin and tried to heal her, "(Y/N) it's no use...he stabbed my important organ so I won't make it" she said and fainted tears were coming out of my eyes.
I felt a hatred inside of me, it was my Crimson Avenger chakra, I got up and gave the mist shinobi a glare "I'm going to kill you!" I screamed and grabbed my sword that was on the ground, I stood up, my body was glowing red and I heard Minato scream out "No (Y/N) don't use it!" but I ignored "come and get me" the mist shinobi said and I started walking towards him slowly as the sword started flaming up. "You hurt the people I cared about...and you'll pay the price for it!" I started running and and he said "you can never catch me!" I ignored what he said and used the blade to summon a technique "shade illusion" I mumbled and in a few seconds the man had a terrified face and I slowed down, "are you ready to die?" I asked and he terrified said "no no I'm not please give mercy" I replied "a life for a life" I then killed him by stabbing him in the stomach, I never wanted to rely on the Crimson Avenger power but I'll never let anyone die again. I then walked to Rin and tried healing her with Kakashi, Obito and Minato staring at me.
I gave them a faint smile and said "I'm sorry for hiding this to you and I promise that you'll never see me again after this..." after Rin was healed you said farewell to Minato "thank you sensei...for everything" and you ran on the trees with Kakashi screaming out "wait!"
Kakashi P.O.V
I screamed out to (Y/N) but she didn't look back...not once, but we had to stay focused on Rin who was badly injured I stared at her and Minato carried it and said "there's no time now, we'll have a chat once we get to the hospital" we all jumped tree from tree and hurried to the hospital, once we were at the hospital, Rin had an emergency operation while the three of us waited outside, "so Minato what happened to (Y/N) back there?" Obito asked, Minato gave a sigh and said "she has the Crimson Avenger inside of her, which means that when emotion gets her, her will to taken over, but it's not as bad. She just uses more chakra than usual and more powerful, sometimes it could damage her so she ran away where no one could find her. Kakashi, I'm giving you a secret mission and that is to find (Y/N) and bring her back and Obito you'll stay here and accompany Rin got that?. All of them were agreed.
~Time Skip~ As 16 year old
Your P.O.V
It's been years since I've left the village and now I'm able to tame the power of the Crimson Avenger...I've changed since then too, so even if I do go back no one would remember me and that also includes the outfit and the sword not so much. I walked in the village with different clothing, many things has changed since then...Minato is now the fourth hokage and Kakashi, Rin and Obito make an awesome team. I went in the hokage's office and said "I'd like to be of service to the The Hidden Leaf Village" I said and there was so many paperwork for me to do I then changed my name to Cecilia , I then was then assigned to work with Kakashi to solve a mystery, I was then greeted every Jounin in the village and then saw Kakashi Hatake. He had different hairstyle but the same fast and mask. Behind him was Rin and Obito "Hey, you must be Cecilia that the fourth hokage said that would be a great help to you" Obito exclaimed with a goofy smile "Oh hey...you must be Obito, Rin and Mr anti-social...oops I meant uhh Kakashi" I said putting my hands on my face. Rin let out a slight giggle "haha that was what (Y/N) used to call you"
I pretended to be confused "uhh who's (Y/N)?" I asked knowing that was me deep inside. "Ohh she used to be our closest friend and Kakashi's crush" Rin explained "w-what?" Kakashi stuttered "that is not true!" "or is it dot dot dot" Obito teased.
