Tsunade POV

"M...Mama." (y/n) said weakly as I put a new damp cloth on his forehead, "You made Mama very upset honey." I said, "You need to slow down. As your doctor, but more importantly as your mother, you will not train without someone there to supervise you." I said, "You know you don't have to train to be a shinobi if you don't want to. I just wanted to make you stronger, strong enough that no one could hurt you." I said, "The choice is yours." I said before I left. 'He reminds me of him.' I thought.

"It's been a few hours, I'll go check on him." I said as I walked back to my room and found (y/n)'s bed empty. "Of course he snuck out." I said coldly.

(y/n) POV

"Great with Zabuza out of commission my workload tripled!" a woman complained as she passed by me, she reeked with the scent of fresh blood. "Blood." I said softly, "Oh so you could smell it? Well, I can't let some kid ruin my mission." She said as she turned to face me.

"Shame, you were a cute kid too." She said as she threw a kunai at me, suddenly someone blocked it, "No one attacks my student and gets away with it." Yumi said, "Sensei!" I said happily, "What are you his mommy or something? I guess it doesn't matter cause I'm gonna have to kill you too." The woman said, "(y/n), you couldn't have picked a worse opponent to fight. That's the Princess of Snow, Sora Tachibana." Yumi said, "And you're the infamous Crimson Flash, student of the late Kushina Uzumaki. You wanted to impress both her and her husband so desperately." Sora said, "At least my sensei cared about me. I remember the Chuunin exams, even though our fight ended in a draw, Lady Kushina was proud of me." Yumi said as she drew her sword, "Well she isn't here to cheer you on now. So let's see if you can protect your student as she did!" Sora said as she drew her sword.

"I might not be one of the seven, but I'm just as capable with a sword!" She said as she slashed ar Yumi, "LOOK OUT!" I shouted as I threw the kunai above Yumi and blocked the hidden second slash.

Yumi POV

"LOOK OUT!" (y/n) shouted as he threw a kunai above my head and blocked a hidden second slash, I looked back at him to see if his Rennegan was activated, but instead, I found that his Rennegan was active in his left eye and in his right a strange new Dojutsu.

'What are you (y/n)?' I thought, "How is a child able to see my Hiken Tsubame Gaeshi?!" Sora said, "What did you expect? He is my student after all." I said as I slashed at her, but she knocked my blade out of my hands and high into the air, I quickly jumped up to it and formed my hand signs, "EARTH STYLE: CRAWLING DRAGON JUTSU!" I shouted as I grabbed my sword and dove deep underground.

(y/n) POV

Yumi dove deep underground, thanks to my Rennegan I was able to see her, suddenly an enormous dragon head mad of earth tried to eat Sora, but she cut through it, "YOU FELL FOR IT!" Yumi shouted as she cut Sora from behind, "HOW!" Sora said in pain, "It's called tactics. I knew you'd try to use (y/n) against me somehow. More than likely through his Dojutsu, so I made a clone and suppressed my chakra. While you were using my student to gain the advantage I snuck up behind you and struck!" Yumi said, suddenly Sora used her Hiken Tsubame Gaeshi again, but I had nothing to throw this time to block one of the slashes, "SENSEI!" I shouted as I ran towards Sora, "RASENDORI!" I shouted as my Rasendori formed in my hand, suddenly it began to grow, "BIG BALL...RASENDORI!" I shouted as I slammed it into Sora, "D...Damn you!" Sora shouted before she was sent flying through a nearby boulder and through a tree. "Big Ball Rasendori?" Yumi said I just smiled at her, "DON'T GET COCKY BRAT!" Sora shouted angrily as she turned to face us. Her left arm was limp at her side, blood dripped down it and fell to the ground. Her right eye was red and tears of blood streamed down the right side of her face. "(y/n) you did very well today, now why don't you let teacher handle the rest." Yumi said as I collapsed to the ground and my eyes returned to normal. "You attacked my student. I will show no mercy!" Yumi said as she held out her right hand, "LIGHTNING RELEASE: RASENGAN!" She shouted as a small golden ball of chakra formed in the palm of her hand, "NOW DIE!" She shouted as she rushed at Sora, "YUMI!" I shouted making her miss her strike, "You're lucky he's here or else I would have killed you. Unlike you, I care what my students think of me, I want them to have a reason to respect me and to follow my example." Yumi said as she walked back over to me and picked me up, "I'll take you back to my house sweetie, you need rest. I'll tell your mother where you are once we get you fixed up." She said as she carried me away, suddenly a deep semi-spherical gash formed in the ground where her attack was, it went on so far that I couldn't see the end.

A/n: It's been a while since I updated this and I just had to make its comeback as epic as I could. I think I did a good job doing just that. Now I have a challenge for you all. 10 points to anyone who can tell me what (y/n) is. I've given you hints in this and the previous chapters, good luck.
