Into The Snake's Nest

"Are you sure that's where Anko is?" Mugen asked while he was on a branch, looking at a staircase leading into underground. Naka was on his shoulder and he gave a few more sniffs before gave his summoner a nod. "Yeah, no doubt about it but be careful because this place reeks. I can smell dead bodies from here even the other animals that live here stayed away." He said and Mugen looked around as there were none alive in the area but them.

"You can go now, you've done a lot already." Said Mugen, while he checked his blades and ninja tools. Naka looked at him, surprised but also worried. "Are you sure? It's not a walk in the park, you know?" He asked and received a nod from the boy. "I'll be fine, don't worry." The boy said with confidence. "Famous last words. Well, if you need me to hold your hand again just give me a call." The cub said and turned into a puff of smoke. Mugen smirked, "Heh, wise ass."

Mugen slowly made his way into the underground base and walked along the candle lit walls. He already had his katanas ready and his eyes were on the move every second in case there was a trap or an enemy. The boy checked every room and was surprised that all of them were normal rooms with just beds, chairs and desks. "Is this a hideout or a refugee camp?" He thought before he kept moving.

"What are you doing here?" Mugen jumped and immediately on his defensive stance after he turned around. He was surprised to see it was his purpled hair friend and grew a smile on his face. "Anko! Damn it, don't scare me like that! Haha! Come on, let's get out of here." He said and was about to grab her hand to take her to the exit. Anko slapped her hand away, looking at the boy in front of her with hatred. "I'm not going anywhere, you liar." She said and her Curse Seal started to glow before black snake scale-like patterns started to cover some areas of her body. "Anko, what are you talking about? And what happened to you? Did that bastard did this to you?!" He asked and Anko's eyes widen of rage from the last question. She leapt forward, punching him and sent him flying. Mugen couldn't see what happened as she was so fast and before he knew it, he felt a sharp pain on his back as he hit a hard wall.

The boy fell to the stoned floor, coughing out blood. "What the hell is going on? Is she pissed for not eating dango for awhile? Ugh, be serious for a bit, will you?! Orochimaru did something to her…Brainwash? Oh, shit here she comes!" The boy rolled to his left to dodge Anko's snake attack which made a hole in the wall. She did some hand signs and spew poison fog towards him, making him run away from her as the corridor was filled with poisonous fog. Mugen looked up at the ceiling and got ready to pull out his sword. "Hope this works…" He mumbled and slashed the ceiling, cutting it open to the surface. The fog stopped chasing him and was sucked out through the ceiling.

Mugen turned around as he heard a slow clap behind him. "Calm and quick. A good idea cutting the ceiling like that, Mugen." Said Orochimaru, snickered at the boy. Mugen gritted his teeth as his mind was starting to be filled with hatred toward the shinobi. "You bastard, what did you do to Anko?! Huh?!" He asked and started growling. Orochimaru was also fascinated towards the boy as he was from a clan that wasn't originated in the Leaf but from the land of Steal, land of the Samurais.

"Mugen, Mugen, Mugen… You're always make me interested in you, you techniques and your clan. But knowing you, you won't want to join me and be my specimen, right? It's such a shame…but you know what is even more shame?" He said and asked. At this point Mugen blocked him out from his head as words coming from his mouth were not important to him. Orochimaru continued, "How dare you just left Anko to me like that? Your own friend?" He asked and made the boy confused.

"What do you mean? Are you out of your mind or something?!" Mugen asked angrily and was about to attack him. "Why don't you just answer his question, Mugen? Tell me the truth. I want to listen from your own lips." Mugen turned to look Anko was walking towards him and Orochimaru. "Again, what do you mean?! I came here to rescue you because this traitor kidnapped you! Not just me but the others were looking for you last night! Kakashi, Guy, Kurenai and Asuma!" He said and saw Anko was getting even angrier. "Why do you keep lying to me…? You of all people..Just tell me that you weren't bothered to save me! It was a lost cause! Orochimaru told me, that you guys followed orders and gave up on me! And thought I would be better off with him because I adored him!" Said Anko, lashing out her anger and balled up her fists.

Mugen was speechless. How could she thought like that? How can she believed him?! "Anko, I-" Mugen was cut off by Orochimaru as he called Anko to come with him and told her to let his men get rid of him. Anko disappeared and reappeared next to her sensei before they both walked into the darkness. "Wait!" He was about to chase them before a lot of ninjas ran towards him and from behind. He looked at them and noticed they were Sound ninjas.

"What are the Sound ninjas doing with a Sannin of the Leaf?" Mugen asked, looking at them and defend himself. "Orochimaru-Sama is our leader now. He showed us his strength and wisdom, and thus we will follow him even if it costs our lives." One of them said and some of them took out their kunais. "I have no time for this…!" He said and as he was about to cut them all open, at the distance from the direction of the entrance were screaming and sounds of crushing as well as explosion. "Chidori!" Kakashi went passed a group of them, electrocute them until they fall to the ground like flies.

Guy used his profession, Taijutsu, beating them one by one while Asuma used his chakra blades and defeated them easily. Kurenai stayed behind and ready to heal her friends if they got injured. "You should watch your back, little girl." Three sound ninjas appeared from her, and was about to capture her when their hands went through her body. The girl's body turned into rose petals and the petals raining down around them until they all three were cut them in an instant.

"You guys…Wait, how do you guys know about this place." He asked them and completely ignore the other group of Sound ninjas behind him. Kakashi was about to explain to before Kurenai stomped past him and slapped Mugen on his cheek. The other three boys were silent as they already know to not get into Kurenai's way when she was angry at someone or just plain angry. "WHAT THE HELL WERE YOU THINKING?! WHY DID YOU WENT ALONE, YOU DUMBASS!" She yelled again and hit him more. Kakashi sweatdropped while Asuma and Guy covered their eyes, painful to see their friend getting beaten up to a pulp.

"I-I-I'm…-" Mugen tried to speak by raising his hand and Kurenai glared down at him. "You what?! Depend on your answer, I will mess that idiotic mind of yours using my Genjutsu!" Said Kurenai. The Sound ninjas just stood there and actually felt pity for the boy despite his is their enemy. "I-I'm shorry..! Ash shoon ash Naka knew vhere she vwas, I jusht move witshout thinking…" Said Mugen. Most epeople didn't understand what he was saying due to the cause his lips were swollen. However, Kakshi and the others understood him and they were also jumped when Naka mentioned where the young Mitarashi was held.

While they were standing there, more Sound ninjas came running down the hall. "You handle Anko, we got your back." Said Asuma, getting into his stance. "What do you say, Kakashi? Want to have a contest to see who gets to beat the most ninjas?" Guy asked and gave the white haired his usual smile. "No." Kakashi replied deadpanned but the Taijutsu didn't back down and before he knew it, Kakashi was competing against him. "Bring her back to us, Mugen." Said Kurenai and she threw an ointment to the injured boy as well as a smile. Mugen blushed and smirked before she turned to the ninjas that were just stood behind him.

Orochimaru was preparing to pack his things and move to another hideout. Anko helped him and Kabuto until something made them stop. Mugen panted and glared at them except Anko. "What's the hurry? You're missing out the party." He said and Kabuto was prepared to fight as he pulled out a scalpel. Orochimaru raised his hand, telling the boy to stop. "How did you get here so fast, Mugen?" The Sannin asked. Mugen smirked, "My friends helped me to bring our friend back. Anko, we're going to play, laugh, tease Guy, take the Chuunin, become Jounin and tease Guy again! They came, we all came for you! Do you actually thought we would follow orders to abandon our friend?! Dumbass! Idiot! You made me opened up to others-" Mugen stopped and blocked Orochimaru's sword attack. "I ain't finished yet!" Mugen yelled and knocked the him back.

Orochimaru's neck went back to its body and he held the sword in his hand. "Kabuto,show our friend that it's already passed his bedtime. I'm done with his laughable ramblings. Come, Anko. Anko?" Orochimaru looked at the girl next to her and saw that she was in shock. She grasp her head, feeling the sharp pain again. "I'm taking you back…I'm taking my best friend back!" He said and ran to Kabuto. Mugen sheathed his swords and pulled one of them out quickly to Kabuto's stomach after he managed to avoid his chakra attacks. The boy with spectacles bent his body over and his face was knocked back up from Mugen's flip kick.

Mugen landed on a wall and launched himself at Orochimaru. Swords clashed and sparks fly as the two fought around in the room. "Kabuto! Stand up, boy! Take Anko through the emergency exit, I will catch up after I kill all the pests." He said and smirked at the boy he was fighting. Kabuto slowly getting up and recovering from the damage Mugen gave him. He was about to grab Anko's hand before four snakes launched at him, pushing him against the wall and made him unconscious. Orochimaru looked at the girl and she glared at him. "Foolish child."

"You're going to pay for what you made me did, Orochimaru!" Anko said and attacked him using her snakes. Orochimaru fought back with his own snakes. "Enough of this. You were a valuable specimen but it's a shame that I have to kill you now." Orochimaru bit on his sword and launched his neck at the girl. Anko was about to attack but her body failed her as she fell on her knees. "Shit!" Anko closed her eyes. She opened them slowly and saw her best friend blocked the attack. She smiled and stood up but as she does, she got a better look on the damage Mugen received. Orochimaru's blade went through his right side chest. "M-Mugen…" She said softly. Mugen slowly turned his head and gave a smirk. "I ain't dying, not yet anyway. As for you, now that I have you where I wanted…" Mugen turned back and looked at Orochimaru. The Sannin tried to pull out his sword but the guard was stuck in between the two katanas. "Tora Style: Swift Claw!" Mugen puched his swords up and quickly slashed Orochimaru's body downward diagonally from his left shoulder to his left hip.

Orochimaru yelled in pain and staggered. He put his hand on his chest and watched a lot of his blood were on the floor. He clicked his tongue and quickly grabbed Kabuto. "Until next time, you two…I'll kill you another time." He said and threw a smoke bomb. As the cloud of smoke dissipates, he and the boy vanished. Mugen let out a sigh of relief and sheathed his swords before falling on his knee. "Mugen!" Anko quickly went to his side, holding him. "It's okay, I'm fine…I'm just glad that I managed to save you.." Said Mugen and smiled at her. He was surprised when the girl buried her face into his shirt, crying. Mugen patted her back and grabbed one of his healing blades, stabbing into his chest.

Not too long after that, Kakashi and the others ran into the room where the two were. They let out a sigh of relief to see Anko was safe and sound but immediately grabbed their injured friend and got out of the nightmare underground hideout. Asuma helped Mugen by putting his arm around his neck. "Thanks, Asuma…" He said and the boy just reply to him with a smile. "You were being reckless again you, idiot!" Kurenai said and she was on a verge of crying but held her tears in. "Now, now Kurenai. Let's leave the lecture and punishment for later. Let's get them home." Kakashi suggested and everyone gave him a nod. Before they headed back to their home, they stopped to look at the bright morning sunrise.

Mugen looked at Anko and she looked at him as well. Mugen gave her a smile but she looked down. Anko felt guilty for not trusting her friends and for getting her best friend hurt. She clenched her fist and swore to herself to kill Orochimaru. "It's the least I can do…It's my responsibility as his student!" She thought.

End of flashback

Anko still remembered that day as if it was just yesterday and as the started to get dark, she decided to head home. Mugen was watching the rain pouring down through his window. "It was raining when we were looking for her…Damn it…every time when it rains, the scars starts to throb!" He thought and rubbed it gently. "Anko.."
