Invasion
"Hey, what did I miss?" Mugen asked as he jumped on the stands and met Naruto, Guy and Kakashi. "You missed me winning, that's all!" Said Naruto and he grinned at him. Mugen smiled and gave him a high five before Shikamaru interrupted their celebration. "You're not the only one who won, you know." He said and Naruto put his arm around him, goofing around with him while Mugen walked up to Guy and Kakashi. "Hey, how was the training?" Kakashi asked and Mugen told him not to worry. "I see, thanks for training him for me. Looks like we're going to see the fruit of his training soon! Oh, the power of youth!" Guy said and his body was on fire by how passionate he was. TenTen looked at her sensei and just let out a sigh.
As the match had begun, Mugen took the time to look around. To see if there was anyone suspicious lurking or hiding. He excused himself from Kakashi and Guy, and went ahead to walk around at the back of the audience. He noticed there were a few Anbus in the stand and noticed some more running around or jumping on the roofs. "Looks like the security is tight." He thought and walked around more. The man stopped when he noticed an Anbu wearing a black cloak was gone and then, a loud crushing sound could be heard from a far along with the sounds of explosions. The first thing that came to his mind was the Third Hokage and he was about to make his way but stopped on his tracks as the world around his was spinning. "Genjutsu, huh? Why does it have to be Genjutsu?! Release!" He said and everything around him was back to normal except that the audience were asleep. Mugen noticed Sasuke and Gaara were gone, assumed they were fighting out of the arena.
"Damn it, we've been had! Hey, wake up! Summoning Jutsu!" Mugen slammed his hand on the floor and summoned Naka. "What do you want?" Naka asked, grumpily as he was woken from his nap. Mugen pointed him to the three head snake at the distance, "Get rid of that thing for me, thanks!" Mugen said and ran off before Naka could say anything. The tiger sighed and jumped from roof to roof towards the monstrous snake. Mugen knocked out the Sound Ninjas that were in his way and smirked when he saw his friends were awake. "I'll leave them to you guys!" He said and jumped onto the roof while Kakashi and Guy knocked the Sound ninjas out.
As he just got himself on the roof, Mugen analyzed the situation. The Anbu was knocked out cold and he saw the Kazekage talking to the Third. Mugen hurried over to the Hokage before an Anbu wearing a black cloak stopped him in tracks by standing in his way. Mugen's hand was over the handle of his katanas. "You're not a real Anbu, are you? You must be pretty clever to disguise as an Anbu without they figure you out." He said and pulled out one of his katanas. The enemy didn't said anything and got into his stance with scalpels in his hands. Mugen looked at him with surprise as he remembered a boy from his past used the same technique and that made him grip onto the sword tightly. "You're that Kabuto brat working for Orochimaru…right?" He said and the enemy laughed at him. "Finally figured it out, huh? I've got to admit though, Mugen. Seriously, you were the thorn of our side the whole time we're here in the Village, with all those security and having the Anbu keep an eye on me." Said Kabuto, removed the mask and threw it away.
Both ran towards each other and their blades clashed. Mugen managed to break Kabuto's guard and kept swinging at him. "So, hows Anko? Is she still traumatize under that smile of hers?" Kabuto asked, taunted the man and it worked. Mugen was riled up by his words and swung widely, causing an opening for Kabuto to kick his side. Mugen hissed in pain and put his hand on his side. "Is that all from the Tiger of the Leaf? Pathetic." Kabuto taunted and looked down on him with a smirk on his face. Mugen pulled out an exploding tag and threw it towards the young man. Kabuto laughed because he easily dodged the tag, "Seriously? You thought you would get me with that?" He asked.
"Not you but him is a different story." Said Mugen, glaring past Kabuto. The man looked where he was looking and his expression changed into horror. "Orochimaru-Sama!" He called out and watched Mugen ran past him. "Where do you think you're going-!" He was about to grab the man before he noticed another exploding tag behind him and jumped away from the explosion. While the Third and Orochimaru had their own stand off, Mugen jumped over the Hokage and glared at the wanted ninja. "Oh, Mugen. How nice of you to drop in, hows Anko by the way?" Said Orochimaru, chuckled. "Still alive and kicking. She has been looking everywhere for you to give you some payback and the same goes to me." Said Mugen. He turned when the Hokage walked up behind him and patted his shoulder. "Let me handle Orochimaru, Mugen. No, don't you argue with me! He is my student and it is my responsibility to correct him." The Third insisted and Mugen stepped down.
"Just don't die, Old Man." Said Mugen, pulling out his other katana. Hiruzen chuckled and had a smirk on his face before he took off his Hokage clothing and reveal his battle armor. "Who the hell are you talking to? I'm the Hokage, I won't die so easily." He said and they both rushed towards their own enemy. Mugen against Kabuto and Hiruzen against one of the Sannin, Orochimaru. Whilst Mugen fought and clashed blades with Kabuto, also knocked out the Sound ninjas that joined in and helped Kabuto, he noticed there was a big purple barrier behind him. "Old man…" Mugen couldn't stop thinking about him. Was he worry too much for the elder? Why couldn't he shake this bad feeling away? "Eyes on me, Tiger!" Kabuto said as he was about to cut the man with his scalpel and barely gave a scratch thanks to the man's reflexes. Mugen blocked the attack with his katana and swung at him, unfortunately he managed to cut his robe.
"What's the purpose of your invasion?" Mugen asked and got back into his stance. Kabuto smirked and chuckled, "What else? To destroy the Leaf, that was Orochimaru-Sama's wish." He said and his expression was replaced with horror or surprise as he saw electricity flowing on Mugen's katana blade. "Oh? Like we would let something like that happen. Have you forgotten that we have a lot of skillful shinobis in this village?" Mugen said calmly and his stance changed, he was ready to strike. "Don't underestimate us just because you caught us by surprise, you damn brat." He said and his katana blade lit up from the intensity of the flowing electricity.
Naka easily jumped form building to building, went past the battles between the Sound and the Leaf below him. "Hey, you slithering bastard! Or bastards!" Naka called out and growled at them before he jumped onto them, ran up on one of them while the others tried to capture him with their mouth. He jumped and scratched one of their eyes, making one of them wriggling and slammed itself into the wall of the village. Naka landed on the injured snake's head, jumped high into the air and he suddenly covered in a puff of smoke. Then, he become bigger, way bigger and easily sat on the three headed snake until they disappeared in a puff of smoke. Naka yawned and turned to look at the direction where his summoner was, "Out of all things you gave me, you gave me the most easiest shit." He said and grunted before some of the Leaf Jounin and Chuunin thanked him for stopping the monster. Naka blushed and turned away from them, "Y-yeah, no problem…Hm? What the hell?!" As Naka turned away from the ninjas, he saw a Tailed Beast, Shikaku. "You guys can take it from here, right?" He asked the little people on the buildings and they gave him a nod. "Alright, I'll leave it to you!" He said and made a dash towards the Tailed Beast. His nose picked up some scents near it and he picked up a familiar scent, the Nine Tails. "Why is that brat doing there? Better protect him or else Mugen is going to give me an earful." He said and changed back to his normal tiger size , as his original size was when he was a giant.
"Lightning Style: Lightning Hammer!" Mugen yelled and slammed his sword but missed the target and instead hit the roof, the impact didn't destroy the building but destroyed the tiles on the roof. Kabuto chuckled, "I'm not as stupid as you think, Mugen. I know that you are stronger than me, I'm just here to stall you for Orochimaru-Sama." He said with a smirk until his expression changed into shock. "I…I can't move my body? It's from the impact..! The shock wave must've got to me and paralyzed my body!" Kabuto thought and cursed at the man. Kabuto looked up at the man before him, glaring at him ignoring the electricity coursing through his body as they felt nothing but tingles. Mugen was about to cut him in half before he noticed the barrier that trapped Hiruzen and Orochimaru, shattered. He stopped and watched the barrier fall to pieces while Kabuto watched in horror. "Did something happened to Orochimaru-Sama?! Tsk, damn you, Mugen!" Kabuto thought while he struggled himself to move. Mugen then turned to another direction and he squinted his eyes to make out what was at the distance. His eyes widened and guessed that brownish monster is the Jinchuuriki from the Sand. "He lost control of it, huh? And looks like he's fighting someone- Gamabunta?! Is Jiraiya over there? I thought he had some business to do… could it be Naruto?" Mugen talked and asked himself. He was worried at first for the boy's safety but knew that Naka would picked up his scent and rushed over there. He also believed the boy could change Gaara as he is also a Jinchuuriki. Mugen turned his back on the scene of the Tailed Beast. "Stay safe…Naruto..!"
As Mugen made his way to the barrier, he noticed a few Sound ninjas retreated but they seemed different from the ones he fought. He didn't put much thought into it as Hiruzen's well being was his top priority. He assumed the elder had defeated Orochimaru, causing for both the Sound ninjas to retreat and for the barrier to break. "Hey, secure that four eyes back there." Mugen ordered one of the Anbu that just woke up. As he got close to the mess, he stopped on his tracks, shocked to see Hiruzen lying on the ground instead of Orochimaru. His blood was boiling and he clenched his fists tightly, "OLD MAN!"
