So this is a oneshot that's definetly AU and yes its 6927, Mukuro and Chrome are siblings and Tsuna a demon fox. The demon foxes don't follow any foke lore, they are of my own creation and can have up to 12 tails. They also 1 demon year is 17 human years. So he's over 250 years in human years but only 15 demon years.

This might get small one-shots added to it after but its a lot of fluff and a little sex at the end.


Tsuna's POV

Tsuna rested in the grass on top of the hill as he watched two teens probably a little older than his human form. He sighed, already knowing they would probably cause even more destruction to happen to the small run down park. He hated teens they were always the same; nosy and destructive.

He watched the teens for a month and surprisingly nothing was ever destroyed, they actually seemed to respect the place. He noticed pretty fast that they ended up living in the rundown buildings on the sight, which Tsuna would admit wasn't safe, but well if you need somewhere to stay then you needed someplace to stay; he been in the same situation before. He sighed from his regular spot up on the hill, and then stood up on all four of his demon forms legs and quickly disappeared after watching them leave the premises to where ever their destination was.

The next day when he was on his way to the hill he was still in his human form because he had been too lazy to change. He had gone shopping for food in his human form because he was pretty sure he couldn't prance in to town with his demon form, yes he was pretty sure that if a 12 tailed fox demon waltzed through town shit would hit the fan. Yes, he was a 12 tailed fox demon which even among his bloodline was rare. As it was he was one of what he was sure was only 5 demon foxes left, and he was the strongest out of all of them, the rest had less than 6 tails well him as a special demon had more tail which in turn meant he had a lot more power. You definitely didn't want to pick a fight with him of all people, because you probably wouldn't live to talk about it. Well anyways he was walking through the thick forest in his human form when he noticed someone was sitting in his regular spot, he was watching from the edge of the forest when the person laughed and then called out for him, "kufufufu I know your there, you can come out."

Tsuna glared at him for a second and then decided to take a chance, so quickly he put up his regular human facade of being a weak, clumsy, scarydie cat up and then walked out shaking like a scared Chihuahua as if his was scared about being caught. He stood beside the blue haired man lying in the grass and just stared at him, the teen looked up, "Why were you spying on us?"

Tsuna looked around, " I...I..wa..a.s..h.. ..re..f. ."

The man sat up, "So you came here ever day at the same time for more than a month, you're kidding right."

Tsuna shook his head, "No, it's the truth...I.. I..s...s... .ar."

Mukuro just laugh, "Kufufufu... I get it... And I understand but can you willingly come with me."

Tsuna nodded, " O..o..o..k."

Tsuna followed behind the blue pineapple haired man, he wasn't worried at all, truthfully he was just fucking with the teens; and if he really wanted to he could destroy them. But he wouldn't because he always tried to be as nice as he could no matter what. Tsuna had made many promises over the years as his friends died one by one around him, and he had promised his dead half fox sister Yuni that he would never kill a human being because they were not at fault for destroying us. We destroyed ourselves and Tsuna refused to kill humans unless forced to because of that promise. But if the line is crossed Tsuna will hurt them, not bad enough for death but bad enough to get rid of them with whatever stupid little idea they had. He sighed as he walked behind the man who walked rather fast in front of him; he wanted to tell him to slow down but knew he would never do it.

Tsuna was honestly did mind human's he had lived with a few before he was given the house. A young woman with purple hair met them at the door and then smiled at the taller teen, "Welcome back Mukuro-Nii-San."

Mukuro smiled at her, "Hello Chrome."

Flash Back

Tsuna had seen her before, she was nice and had gotten lost in the forest exactly a month ago, it was literally the day after they had arrived. He had been walking extremely deep in the forest until he found the girl sitting alone, he had asked her, "Why are you here?"

She had looked up at him a little spooked, clearly she hadn't noticed he was there yet, "I'm waiting for Mukuro-Nii-San to find me. I got lost when I went for a walk."

Tsuna nodded, "Do you want me to show you the way out, you're pretty deep."

Chrome had nodded, "It would be nice if you could, thank you."

Tsuna nodded as she stood up and followed him, he began to walk towards where he knew she was staying, he smiled, "I don't mean to be rude but could I perhaps ask your name."

She nodded, "Chrome... Chrome Dokuro."

Tsuna smiled as he turned to glance at her, "Nice to meet you Chrome, my names Tsuna."

Chrome smiled and nodded, "That's a cute name."

He just laughed as they continued walking, for the rest of the walk they didn't talk and when they were coming to the edge of the forest he stopped and pointed to the building visible just a ways away, "There's the way out, if you just keep walking you'll be okay."

Chrome walked a head of him and once he was out of her field of vision he quickly left, he walked fast back in to the middle of the forest, she had been rather close to his house so he thought that showing her out was the right idea. He didn't want people to find his house because they could hurt themselves on the barrier surrounding it or he might have to leave it, which was always annoying. It had happen at least 10 times in his over a 250 years of life, in fox years he was only around 15 years of age but in human years he had lived their life time over at least twice if not three times.

Tsuna's POV

Chrome saw Tsuna right then and smiled, "Hello Tsuna, thanks again for your help."

Tsuna just smiled, "It was really nothing."

Mukuro glanced at Chrome, "When did you meet him?"

Chrome looked at Mukuro, "Remember when I told you that I got lost in the forest, he's the one who showed me the way out."

Mukuro turned to look at Tsuna, "Kufufufu...Well that's interesting..."

Tsuna kept his scared personality up, "Um..wh..h..a.t...did.. you need...me...to come.. here...f... ."

Mukuro sighed as Chrome looked at Tsuna, "There's no need to be scared of Mukruo-Nii-san; he would never hurt someone who helped me."

Tsuna nodded as he glanced at Chrome, "Then..why..am.I..here?"

Chrome looked at Mukuro and sighed, "What did you do to scare him so much."

Mukruo just laughed, "Kufufufu...absolutely nothing."

Chrome glanced back at Tsuna, "Then why does he look like a kicked puppy?"

Mukuro looked at Tsuna, "He's been acting like that since I found him."

Chrome looked at Tsuna, "Oh..yeah Tsuna can I ask you how you knew I lived here?"

Mukuro frowned, "He knew because he's been watching us since we got here."

Tsuna knew the facade was over when they both stared at him so he dropped and started talking in a calmer voice, "I've lived in the house in the woods since I was born. I've always sat on that hill daily, and coincidently I saw you the day you guys moved in."

Both of the people in the room instantly noticed the change in his personality, he still wasn't being mean in any way, he just wasn't acting scared about his situation anymore. Quickly he figure out changing the way he acts is a bad idea; but it was already way too late all it had done was spark the blue haired teen's curiosity. Mukuro smiled, "Then you won't mind showing us your house so we know you're not lying to us."

Tsuna sighed, he couldn't believe he was going to let two humans control him, but he didn't see anything wrong with it. So he turned and began to head out the door, he could hear them walking behind him, "Are you guys sure, it's a really long walk."

Mukuro looked at him, "That's fine. Just keep walking."

They had been walking for at least an hour when they began to actually get close, when they were getting really close Tsuna released a small amount of magic to destroy his protective barrier to allow the humans in. He looked behind him at them and they were quietly walking clearly Chrome was tired, "Were almost there."

They walked for another 10 minutes until finally they had arrived, both were surprised by his house, they had expected to see maybe a small cabin, but it was a very large almost temple like house. They were amazed that no one had seen it yet; usually people would know about a place this large being nearby. As they were walking Mukuro and Chrome stopped to look at the strange statues, Chrome looked at Tsuna, "These are foxes deity statues right?"

Tsuna nodded, "Yes, but they used to be used to worship the local fox demons before my mother bought it when I was born."

Mukuro hummed, "Interesting, so do you live in such a large place alone?"

Tsuna nodded at the strange question, "Yeah, my mother was my last of kin and my sister died before that, and well they died a long time ago."

Chrome looked at him rather sad, "How can you handle living alone in such a place."

Tsuna just smiled a very sad smile, "You get used to it, being alones not as bad as it seems."

Chrome frowned, she remembered how lonely it was for her before Mukuro had found her, he was her older half brother they had the same father but their mothers had been different, they hadn't lived together. But Mukuro had saved her from her abusive father when she was 6, they had been together since then traveling together and without any money or parents they could only stay in the park. But neither one complained about their situation as long as they were together. She almost looked like she was going to cry.

Tsuna noticed and forced himself to smile trying to cheer her up, "its fine Chrome, trust me I don't mind being alone. I got used to it a long time ago."

Mukuro just ignoring their previous conversation went over to Tsuna and asked, "How can you afford such a place?"

Tsuna looked at the ground, "I never said. I didn't have any money did I?"

Tsuna turned and headed inside, as they entered Mukuro noticed a lot of stuff inside the rooms, there were kimonos, jewelry and tons of other really expensive items. He could see foxes everywhere they were painted on the walls on some of the jewelry and even on some of the cloths, "It doesn't look like this temples shut down foxes are everywhere on everything."

Tsuna nodded as he looked at a small chain Mukuro had picked up with a fox charm on it, "Even with it shut down some still respect and believe the foxes are still here so they make offerings, so I go every morning to collect the offerings from the places around the temple and bring it all here, If you see something you want you can take it the foxes aren't here so they won't care."

Mukuro put the strange necklace in his pocket as Chrome picked up a strange trident from the corner and looked at Mukuro, "Nii-San this looks like yours doesn't it."

Mukuro glanced back, "It can't be, our father said he gave it to a white fox demon he saw years ago when it saved my mother."

Tsuna's eyes widened in memory of that day, he had saved a young woman when she fell from a Clift so high that would have instantly killed her. His instincts had told him to save her and he did, luckily the woman's husband was a user of mist flames so he could see the fox, he remembered the day it was offered to him perfectly. He smiled again at Chrome, "You can have it if you want."

Chrome looked at him, "Thank you."

Mukuro looked at it curiously, there wasn't even a speck of dust on it, and then looked around; there wasn't any on anything else either. But he decided to just ignore it instead.

Tsuna smiled as he thought about something then, "If you guys promise to not cause trouble you can stay here, it would probably be more comfortable then that park; and safer."

Chrome looked at him excited, "Really?"

Tsuna nodded, "But you have to promise not to go to the right side of the house, it's not in the best condition and it could be dangerous."

Mukuro looked at him, "You're sure you want strangers like us to live here, you don't even know us."

Tsuna smiled, "its okay, I'm sure it will be fine."

Mukuro turned to Chrome, "Do you want to stay here?"

She nodded, with that it was decided, so Tsuna escorted them to the free rooms that they could stay.

X-X-X-X-X-X-X-X-X-X-X

Mukuro's POV

He walked through the hall from his room towards the large bathroom, this house was huge and he had been here for at least a month now but still wasn't use to it. He had some clothing that Tsuna had given him money to buy in his arms as he walked down the hallway. He got to the bathroom door and was about to open it when he saw someone out of the corner of his eye walking in the area of the house that wasn't safe. He walked over and looked around the corner, he swore he saw Tsuna who had turned around the corner at the other end of the hall and out of curiosity he followed him.

He reached the back of the house and he saw a door that was open, when he walked to the door he saw a large rock that was flat on top, that underneath had a large pond. But what spooked him was the large white fox he saw sitting on the rock, as if it was lounging in the moon light like it was no one's business. Mukuro knew what he was looking at, it was a rare white fox demon, he was staring at the demon and watched as its tails swished in the air, he counted and was surprised when he saw twelve. It was the demon that had saved his mother before he was born; he noticed the orange rings on its tails and ankles, and the orange flame that leaked from the rings. It was so pretty he had never seen something like this before; he had only heard the tales about its beauty from his mother before she had died.

He didn't know why but he wanted to touch its fur, he took one step forward out the door way on to the grass and instantly the large demon opened its eyes. They were a vibrant but calming orange color, and they made him stop instantly in his tracks, the beast stood up and walked over to him and breathed out, he swore Tsuna had said that the fox demons had left, when clearly they hadn't if this one was here. He heard the fox whisper in his ear, "Mukuro...you're not supposed to be over here."

Mukuro looked up at the now talking monster who had sat down on the grass in front of him; clearly it was trying to think about what it should do now. It reached its head over and Mukuro saw it grab clothing from the corner by the door, and after it set the clothing down in front of itself its tails slowly began to disappear one by one, as the creature got smaller. Soon it took a human form and right in front of him it changed in to clothing before it turned to look at him, " Mukuro why are you over here?"

Tsuna now stood before him as he just stared, "You're a..."

Tsuna nodded, "Yeah I'm a fox demon, I didn't notice how much you look like you mother at first but I remembered when Chrome talked about the staff they gave me after she almost died."

Mukuro grabbed his arm, "Why would you endanger yourself by allowing us to stay here?"

Tsuna looked at Mukuro and smiled, "Was I wrong in trusting you then, would you rather still be living on the street with you sister."

Mukuro shook his head, "No. But what if I had attacked you, I'm an Illusionist and you know it so what if I had tried to kill you for your powers."

Tsuna looked at the ground, "Then I would be dead now wouldn't I, it's not like that would be such a bad fate."

Mukuro looked at Tsuna who clearly didn't understand the situation, "What if you had died; you should have stayed alone its better than being killed isn't it."

Tsuna looked at Mukuro and snapped, "What do you know about loneliness, I've been alone for more than 50 years maybe I'm tired of it, I'm only 15 if you go by fox demon years. I don't want to be alone anymore."

Tsuna had broken in to tears now as he wiped his arm over his eyes to try and stop himself, he knew he should have more pride then to cry in front of a human, but Mukuro seemed to destroy his barriers that he always had up to protect himself from others before. Mukuro took a step forward, " Tsuna... Calm down I get it now."

Tsuna glanced at him as his emotions began to lose control and his tails started to appear again, his eyes started flashing rapidly between his demon orange ones and his human brown ones, "But you don't know me, I'm even younger then you mentally and I've been alone a lot longer. I thought I could handle it but I still need someone and you guys being here made me realize it."

Surprisingly of all the things Tsuna had expected Mukuro to do it wasn't what he did, he had hugged him, one of Tsuna's tails cut Mukuro's cheek out of fear from the sudden contact with the taller man who he thought wasn't the gentlest before, "Calm down your losing control of your magic if you keep this up the barrier's all around here will drop so calm down. Put your tails away first."

Tsuna breathed as he gained control of himself again, he had never lost control like that before, he looked at his hands and at the cut on Mukuro's cheek as he realized what he had done, "I how could I... I hurt..you. I'm a monster that shouldn't be with anyone, all I ever do is hurt people."

Mukuro gently ran his hand threw Tsuna's hair, Tsuna looked down as he was pulled towards the others chest, "You're not a monster, you beautiful demon, and you're not a bad one you saved my mother so calm down, your just scared of being alone."

Tsuna was angry with himself, "And I acted all strong in front of Chrome before."

Mukuro smirked and continued to rub his hand threw his hair, "You were just acting strong we could both see the pain in your eyes."

Tsuna stopped himself from crying, "What am I doing I am the strongest fox demon left and I'm crying."

Mukuro took his hand, "Everyone needs to cry sometimes."

Tsuna sat back, "So can I ask why you're on this side of the house?"

Mukuro laughed, "Kufufufu... I saw you walking here and you said it was dangerous so I followed behind you."

Tsuna smiled and said, "Nosy."

Mukuro smirked, "Well sorry then for being curious."

X-X-X-X-X-X

Tsuna and Mukuro sat by a tree in an opening in the bush, Mukuro had Tsuna pinned up against the tree as they kissed. When Mukuro found out the truth he noticed that Tsuna started acting more open with him, and well with the trust he was receiving and how cute Tsuna was it didn't take much for Mukuro to fall for him. So they had started to become closer, and exactly 2 weeks ago Mukuro had told Tsuna he wanted him to become his and surprisingly Tsuna had submitted. Now whenever they were alone they would kiss and they loved each other so much. Even with his own sister Mukuro seemed to be very jealous which Tsuna actually found rather amusing.

Tsuna wrapped his arms around Mukuro, "We should do this at home, wait until then...ah.."

Mukuro sucked delicately on one of Tsuna's nipples, and Tsuna could hardly handle it as he moaned in pleasure, Mukuro noticed instantly how much more sensitive Tsuna was then a normal human. His reactions were so much more adorable to, it just made Mukuro want to ravish the younger constantly. Mukuro pushed Tsuna back again and held two of his hand with one, he put his other hand out and instantly there was a large bed in the middle of the opening. He quickly picked Tsuna up and carried him to the bed and then continued.

Mukuro and Tsuna played until the day turned in to night and Tsuna had climaxed so many times. Mukuro was moving so fast at the moment because of how close he had come to his climax. He moaned out as he shot his load out in to Tsuna, quickly afterwards Tsuna also orgasimed, he moaned in to Mukuro's mouth as they continued to kiss again and again.

When they finished they both were lying completely exhausted on the illusion bed that Mukuro had made, Tsuna sat up, "We need to head back before Chrome gets worried we were only suppose to have gone shopping. We've already been gone for far too long."

Mukuro leaned forward as his arm draped around Tsuna pulling him back down as a sheet appeared on them, "Stay down... Chrome will be fine it's not hard for her to figure out where we are or what we're doing. So go to sleep I can see the strain on your body from here if you move to much you'll make it hurt more."

Tsuna sighed, was Mukuro forgetting he was a demon, Tsuna couldn't feel any pain because his body was already healing the strain it had taken. He smiled and didn't tell Mukuro though thinking that instead he would just enjoy the nice silent cuddling time.


I hope if you read it all you enjoyed I think i really screw Mukuro up and well Tsuna was made that way purposely. This written for my own amusement and to get plot bunnies out of my head so it not the best work I've done, but I didn't mine it so I posted.

Lol and i i spelled the word orgasimed wrong my iPad was being a bitch changing it to organized and other stuff.
