Naruto turned to look around the area as he sat on top of the Kage box of the chunin exams unseen. 'Something is off' He thought as he tried to figure out what it was while looking around. Eventually he spotted the Konoha twelve and a small smile graced his face. He looked over them seeing the teams and smiled when he looked at Kurenai 'I see she is doing better, good to know'.
Looking down he saw that Sasuke and Gaara were fighting watching as Sasuke jumped back and landed against the wall before grabbing his wrist and forming the chidori. Sasuke took off towards Gaara at a fast pace before slamming the chidori into Gaara's sand managing to land a hit on him. Gaara screamed in shock as he saw his own blood and sand began to move around him and covered his right side. Naruto had to look away as feathers began to fall around the area and he watched it put people to sleep 'genjutsu but why' then he saw it Oto and Suna nin coming out of transformations and beginning to attack.
Naruto placed his hands in the ram sign "Kai" he yelled dispelling the genjutsu from the Genin around him before he jumped down into the stands. Unsealing his scythe from the storage seal on his arm Naruto began to fight off Oto nin that were trying to attack a group of genin. One Oto nin managed to sneak up behind Naruto surprisingly but was instantly kicked into the wall hard. Naruto noticed this and turned around to see Gai standing there and looking at him. "I don't know who you are but you seem to be a Youthful Ally I will fight with you" Gai said in his youthful way as he punched a Suna nin into a wall. Naruto nodded after hearing what Gai said and got down into his Reaper stance as Gai got into his own stance beside Naruto as they stared down there opponents.
With Kurenai
Kurenai had dispelled a lot of the Genjutsu once the Invasion had started and now she was trying to help evacuate the civilians that were in the arena. "Please don't panic and remain calm" Kurenai said to the Civilians she put some Oto nin around her in a genjutsu to make them think they weren't there. The Civilians nodded fearing for their lives but trusting the shinobi infront of them. Kurenai began to help the Citizens out of the arena and towards the Hokage monument where they could go inside into the passageways and wait until the invasion was over but Iruka jumped down and nodded to Kurenai "I got them you help the others fight the Suna and Oto nin". Kurenai nodded back understanding and turned back around to help fight but what she saw surprised her.
Kurenai looked on in surprise at the stands above her watching as Gai and the Mysterious man that saved her that time worked together as a team to fight off Oto and Suna nin keeping them away from a group of genin. She watched as the man swung his scythe around and stopped short of his opponent before sliding back as Gai jumped over his head and brought his foot around hard hitting the Oto nin in the face sending him flying towards her. Kurenai stepped out of the way quickly and watched as the body collided with a Suna nin that had been coming from behind her 'Right Kurenai stay focused'. Kurenai turned to a group of five Suna nin and went through handseals putting them in a genjutsu that made them see each other as enemies and begin fighting.
Back With Naruto
Naruto swung his scythe at the final nin that was fighting him and Gai and decapitated the man before turning back towards the Genin and Gai. "It was a pleasure fighting with you my Youthful friend but i will now take these genin to safety" Gai said as he turned to talk to the Genin. Naruto nodded understandingly and quickly made a clone to go after Gaara and another to go to the academy. Naruto then looked up to the Kage box watching as the Third Hokage fought with Orochimaru.
Orochimaru was winning due to the first and second hokage actually figthing Hirzen and Naruto knew he wouldn't last long and had to find a way into the barrier to help his grandfather figure. Naruto jumped up onto the roof of the Kage box and scanned the barrier before taking a deep breath. "Well time to try that" Naruto walked directly at the barrier and walked through it as his body fazed through the walls of the barrier before reforming on the other side and he glared at Orochimaru. The Snake Sannin looked at the boy like he was looking at a ghost "it's not possible" He yelled and sent Tobirama to fight Naruto leaving Hashirama to fight Hiruzen.
Naruto didn't have time to act as a water dragon appeared from the air and shot at him but was surprised when a earth wall erected in front of him and he turned to see Hiruzen smile. Naruto nodded and ran at the wall as it descended back into the ground straight at Tobirama his scythe glowing with a purple and silver chakra. Tobirama ducked as Naruto brought the scythe towards his neck receiving a cut from his hair as he brough his foot up to catch Naruto in the chin but Naruto jumped back in time to avoid it and swung his scythe around again this time going for Tobirama's torso. The second not having anything to substitute with or to avoid by was grazed by the scythe and it cut a bit into his torso but he wasn't expecting it to rip the soul out of him 'please return this to where it belongs Shinigami-sensei' Naruto thought as he pulled his scythe back. Naruto turned to see Hiruzen finishing up with Hashirama but all of a sudden the First Hokage dropped and the body scrapped away revealing a Oto nin when Naruto looked around He realized that Orochimaru had retreated.
Naruto nodded and looked over to Hiruzen "Call your shinobi back" He said knowing the civilians where in cover now. Hiruzen decided to trust Naruto on this and looked around catching Inoichi "make it so everyone can hear me" Inochi did so and hiruzen said "Fall back if you don't you will wind up dying a unneeded death". All Konoha shinobi begun to fall back leaving all the Oto and Suna shinobi that had not retreated in a large group watching them retreat and begun to chase before Naruto jumped down infront all of them "heh what are you going to do your one person" one Cocky Oto nin said as Naruto began to spin his scythe the chakra getting stronger around it. Naruto swung in a large horizontal swipe "Soul Release: Soul Reaping Wave" Naruto said as a large wave of purple and silver chakra shot from his scythe and went through all the Oto and Suna nin with great speed but not causing any bodily harm but still they all dropped dead as their souls where ripped from their bodies.
Naruto dropped to one Knee 'damn that one still takes a lot out of me' He thought as he struggled to get back up but felt a gentl hand on his shoulder and turned to see the hand on his trench coat was a feminine one. "Don't push yourself you need some rest" He heard an d looked around more to see that the voice had come from none other than Kurenai Yuhi and he nodded. Hiruzen walked to Naruto and said to him "thank you for your help young man would you mind telling me your name" He asked acting like he didn't know already. Naruto inwardly cursed the old man for doing that and thought quickly "my name is not important but if you want to call me something just call me Reaper" Naruto said. "Very well then Reaper-san" Hiruzen said before he called over some medic nin to tend to Naruto.
Naruto began to try and stand up again managing to get to his feet. Turning around the sight of alot of the Older shinobi looking at Naruto with Grateful looks shown on their face was what greeted him. Naruto couldn't help but smile under his bandages. Naruto took a step to begin to walk but fell forward as his energy left him and he fell passing out.
