Disclaimer: I do not own Katekyo Hitman Reborn

Summary: What if Tsuna had a little brother named Natsu? What if Giotto was their older brother? This is a story about Tsuna and Giotto becoming over protective of their little brother.

Tsuna: 18 Year old, Brown hair

Giotto: 22 Years old. Gold/Blond hair

Natsu: 15 Years old, red/orange hair

Natsu had been upstairs getting ready for a date with his boyfriend Byakuran when he heard his mother call him to come downstairs. "Coming okaa-san!" Natsu yelled as he ran down the stairs, but he ended up tripping instead. "WAAH!" Right before he hit the ground he was caught by someone.

"Jeez Natsu you should be more careful." Giotto said. "Giotto-nii!" Natsu yelled as he hugged his older brother.

"Is Tsuna-nii here also?"

"Tsu-chan is in the kitchen with okaa-san that's why she called you down." Giotto said with a smile. "Why are you so dressed up?"

Natsu didn't hear the question because he already had ran to the kitchen and was hugging his other brother Tsuna.

"TSUNA-NII!" Natsu said happily as his brother returned the hug. "What are you doing back home? I thought you were in Italy with tou-san." He asked after he let go of his brother.

"Hehe well otou-san let Giotto and I visit you guys for a vacation." Tsuna said lying about why they were really there.

"Ah Natsu aren't you going to be late for your date?" Nana said to her youngest son.

"AH your right kaa-san I have to go! Bye Tsuna-nii, Giotto-nii!" Natsu yelled as he ran out of the house.

Giotto and Tsuna had frozen when they heard the words date from okaa-san.

"Okaa-san who is Natsu going on a date with?" Tsuna asked.

"He Is going on a date with his boyfriend Byakuran." She said.

Both Giotto and Tsuna both looked shock before concern entered their eyes.

"Kaa-san do you know where Natsu's date is at?" Giotto asked.

"Hmm? I think he said at the park." She replied.

After she said that the pair ran out of the house in search of their little brother. They both had ran to the park next to his school where they saw Byakuran holding Natsu while they walked.

Giotto and Tsuna hid behind a tree before they saw them.

Natsu had given Byakuran a kiss before they went to walk, but right before they left he heard some noises behind them and turned around.

"Whats wrong Nat-chan?" Byakuran said has he smile and pulls the boy closer. "Are you afraid to be here with me?"

"No its nothing Byakuran, I thought I heard something." He said.

Byakuran had turned and glared at the space Giotto and Tsuna were hiding at.

"Tsuna we have to get Natsu away from him. He doesn't know about the mafia or anything he is in danger." Giotto said to his little brother.

"I know Giotto im thinking of a way to get to him."

Byakuran had left a little note that Tsuna had seen he dropped so he grabbed it when they weren't looking.

When he read the note he froze. 'If you try to stop me I'll kill your little brother'

Giotto had taken the note from Tsuna and read it also, but after he did he grew an angry expression and looked like he was ready to kill.

"Tsuna call your guardians we are getting Natsu now!" Giotto ordered him.

Tsuna had left to call his and Giotto's guardians while Giotto went to follow them incase Byakuran did anything suspicious.

While Giotto was watching he saw Byakuran slip something into Natsu's drink when Natsu was looking away. When Natsu turned back to drink he didn't notice the pill Byakuran slipped in.

Tsuna had come back after Natsu drank the strange pill and saw his brother in rage looking like he was about to rip apart Byakuran's head. "Whats wrong Giotto?"

"He just drugged Natsu with something! I saw it!" He yelled in rage.

Tsuna was trying to calm the raging blonde haired man while he tried to calm himself.

Byakuran had led Natsu to his apartment building while Natsu was still unaffected by the drug.

Giotto and Tsuna had their guardians with them when they saw Byakuran take Natsu into the building.

Asari and Yamamoto were trying to calm down their raging skies from massacring the whole neighborhood. Hibari and Alaude (sorry I don't know how to spell his name right) were planning to arrest and kill him for doing this to Natsu.

Everyone there had a special complex for Natsu whenever is hurt or sad someone would always help cheer him up. When they heard he was in trouble all hell broke loose.

Inside the building

Natsu felt something was wrong a while after they went to watch a movie at Byakuran's apartment. After Byakuran left to go to the bathroom Natsu felt weak and his vision started blacking out. The last thing he was before he passed out was Byakuran smirking.

When he woke up again Natsu was tied up and gagged on a chair. He couldn't move because the drug had made him weak.

Natsu looked around and saw he was in a locked room with a sealed off window. He heard the door open and saw Byakuran slowly coming closer.

Natsu felt fear run through his veins as Byakuran came closer until he stopped right in front of him.

"Hi Nat-chan~~" Byakuran said with a smile that just screams pain.

"Mfhh!" Natsu couldn't say anything with the cloth tied around his mouth. 'What is he going to do to me!?' he thought in panic.

"Let's play a game Nat-chan. Every time you tell me about your brothers the higher chance I'll let you go!" Byakuran told the tied up teen.

Byakuran could see the fear in Natsu's eyes as he came closer to him.

He removed the gag from Natsu's mouth and asked the first question. "Where do your brothers work?"

"I-Italy." Natsu replied. He was sure he was going to die unless he someone saved him.

"What is your oldest brother's job?" He asked with amused smile.

"I-I do-don't know." Natsu replied.

"Hmm~~ wrong answer!" Byakuran said as he punched Natsu's face with his fist and knee.

"AHHHH!" Natsu felt all of the pain as Byakuran continually punched and beat him.

"Now I'll ask again what is your brother's job?" Byakuran said again getting a malicious look in his eyes.

"I-I don't know." Natsu tried to say but it turned into screaming as Byakuran started hitting him again.

"AHHHH!" Natsu screamed as he passed out from pain. The last thing he heard before he passed out was 'buonanotte mio piccolo marshmallow' then everything went black.

Back outside while Byakuran was torturing Natsu

"Tsuna we are going in there now!" Giotto yelled at his brother trying to restrain him.

"Giotto we can't until Byakuran leaves! If he sees us trying anything Natsu might get killed!" Tsuna said trying to keep up his strong act.

Giotto was about to reply when everyone heard a scream come from the building. Everyone froze after hearing the scream.

Alaude, Hibari, Mukuro, and Daemon looked ready to kill. G and Gokudera's faces both grew stiff. Yamamoto and Asari both lost their grins and a serious expression had appeared. Lampo and Lambo both had a frightened expression at the scream. Worst of all Giotto and Tsuna looked like hell broke loose.

Tsuna had broken down the wall of the building when Giotto gave him the signal. Their plan was to save Natsu where ever he is in the building. Everyone had split up in search of the redheaded teen. While they were searching everyone heard more screams and they were getting closer. Suddenly the screaming stopped after a while

"Knuckles and Ryohei get ready to use your sun flames if needed." Giotto told them.

Everyone got closer to the door as Giotto and Tsuna started opening it. What they saw broke their hearts. They saw Natsu bloody and beaten tied to a chair in the middle of the room.

"Natsu!" Tsuna yelled as he ran to his younger brother to help him. Natsu who had opened his eyes at hearing the door being opened whimpered and flinched as soon as Tsuna had tried to hug him.

"NO! NO MORE!" Natsu yelled thinking it was Byakuran. Everyone could tell Natsu had been through a traumatizing experience and he need as much help as he could to return to normal.

"Natsu calm down! It's me Tsuna!" He yelled trying to calm his hysterical little brother.

Giotto couldn't take it anymore so he grabbed Natsu and held him close to him and Tsuna whispering comforting words to him.

"It's ok Natsu it's only us. We won't hurt you believe us." Giotto said trying to comfort him.

Natsu seemed to calm down a bit hearing Giotto's voice, but he started letting loose his emotions and started crying while hugging Giotto and Tsuna.

After holding Natsu for a while his cries started turning into hiccups until he passed out from exhaustion.

"Knuckles, Ryohei please heal Natsu for us." Giotto asked the sun guardians.

After seeing his little brother like that the two older brothers had both promised to protect him from anything that could pose as a threat to their family.

Natsu had woken up after 2 days of sleeping to see Tsuna sitting by his bed reading. When he tried to move a sharp pain ran through his body making him gasp. Tsuna who had heard the gasp turned to see Natsu trying to get back up.

He pushed Natsu down carefully making sure not to hurt him more, but as soon as his hand touched Natsu he flinched out of instinct. Seeing this broke Tsuna's heart even more wanting to comfort his little brother he gave him a hug to calm him down.

While hugging Natsu, Tsuna started crying saying apologies to Natsu.

"I'm sorry Natsu. It's my entire fault your hurt! Im a horrible older brother I bet you hate me right now!"

Natsu tried to tell Tsuna that it isn't his fault, but he couldn't form the words to speak. He was too scared to speak he kept thinking about what Byakuran did to him.

Natsu could only hold Tsuna as he kept saying he was sorry over and over again. Giotto had came into the room to see Natsu holding a crying Tsuna. He hurried over to them and enveloped both of them into a hug.

"It's ok now Tsuna." Giotto said trying to calm him down. "Natsu… are you feeling better?"

Natsu looked at Giotto and replied with a silent 'im ok', but Giotto could see the fear evident in his eyes.

Giotto wished he could have found his little brother sooner, but the past is done and now he has to help him heal.

Tsuna had let go of Natsu after he calmed down and helped Natsu lay down so he could rest. "Natsu you need to rest if you want to heal faster.

Natsu had fallen asleep while Tsuna and Giotto talked about what to do to protect him. "Maybe we can ask Fon to train him in self-defense." Tsuna suggested.

"Natsu shouldn't do anything yet not until he is completely healthy and we have helped him get over the trauma." Giotto was about to continue when Natsu started thrashing violently.

They could hear him continue to say 'No, no stop please stop'. Tsuna had hugged Natsu's thrashing body while Giotto tried to whisper comforting words to him.

After Natsu calmed down the two brothers were able to relax a bit thinking that another nightmare shouldn't happen until a little later.

"Giotto can you come down here please?" Nana asked.

"I'm coming okaa-san." He said, right before he leaves the room he says to Tsuna "Keep a close eye on him I'll be right back.

Giotto came down to see his mother in the living room waiting silently. "Is something wrong okaa-san?" he asked cautiously.

"Giotto tell me what really happened to Natsu why was his expression filled with pain? Did something happen to him?" she continued to ask him.

"Okaa-san… the truth is."

How did you like it? Is it any good. I came up with this idea during school and I just couldn't wait to write this! Im sorry for the other story I wrote but I lost all my ideas for it after a while. I'll be adding more chapters later on if you want me to continue this though.

Have a nice day! –Teemo-kun
