3rd Person's P.O.V. 

"Now that that is done with. Explain," Kimura demanded.

Natasha and Clint glanced at one another before relenting.

"My partner and I belong to a secret organisation which is exactly why we knew that Tsuna was being hunted by hitmen," Natasha informs. 

"What is this 'secret organisation?'" Kimura inquired.

"We're not allowed to tell you," Clint replied.

"Why should I believe you? You've been suspicious since you entered the hospital, I should report you the police and keep Tsuna here," Kimura argues.

"You can't keep Tsuna here," Clint counters.

"Why not?"

"Because Tsuna is still in danger," Natasha answers, "those guys won't be the last, there will be more hitmen coming after her and if she stays in the hospital then you're putting other patients and staff at risk."

"Then where do your propose we put her?" Kimura questioned. 

"We can take her," Natasha offers. Clint glances back at Natasha and sees the conviction in her eyes. Kimura was about to object, violently when Clint backs her up.

"Having Tsuna in our care means she'll be safe, there's no one who'll dare come close," Clint explained. Kimura contemplated this, she still didn't trust the two but they made sense and she knew keeping Tsuna would bring more danger to her hospital.

"Fine," Kimura caved, "but as I said before, I don't trust you so I want Tsuna to stay here overnight and I want to see your superior. These are my terms and conditions," Kimura demanded, her tone left to room of argument. 

"Ok," Natasha and Clint agreed.

"Am I staying with you, Natasha Oba-San, Clint Oji-san?" Tsuna asked.

"Yeah," Natasha replied.

Tsuna had a faraway look in her eyes, "Does someone really want to kill me?" Tsuna asked, sadly.

"We won't let that happen," Natasha reassures, hugging her tightly.

"Arigatou," Tsuna returned the hug.

The next day

"So this kid is linked with the Vongola Mafia and you want me to convince the hospital director that said kid will be safe in S.H.I.E.L.D's care?" Coulson summarised, raising a brow.

"Yeah, basically," Clint shrugs. Natasha just carries on playing with Tsuna.

"Director Fury is going to be pissed," Coulson tells them.

"That's why I called you first," Clint grinned, cheekily. "Maybe you'll deal with Fury for us?"

"You can die by yourself, Barton," Coulson retorts, "you're lucky she's adorable."

"Thanks Phil," Natasha said, grateful.

"Thank you!" Tsuna beamed.

"You're welcome," Coulson replied, smiling softly. Coulson spent the next hour discussing with Kimura about Tsuna. He eventually manages to convince the doctor that Tsuna would be safe in America and that in order to keep her safe, her death needs to be faked by the hospital. Everything went well and now, the trio of adults and Tsuna were on their way to the airport.

"Where are we going?" Tsuna asked, holding Natasha's hand as they walked through the airport. Tsuna was wearing a black wig which covered most of the bandages wrapped around the right side of her face.

"We're heading to America," Natasha tells her, "you're going to live with me from now on."

"Really?" Tsuna's eyes sparkled and at Natasha couldn't help but smile at how excited she sounded.

"Yep," Natasha nodded and they all got on the plane.

Next month

It's been a month since Tsuna went to live with Natasha, Fury was initially against having Tsuna since it would have brought a lot of unwanted conflict from Vongola but was eventually convinced by Clint and Coulson. He met Tsuna himself and though he denies it vehemently, he fell under Tsuna's spell just as the other agents did.

Natasha went under the alias 'Nadya Fedorov,' with Tsuna posing as her niece with the same last name. Tsuna was thriving in America well, she was actually smart for her age. She no longer wore the bandages but she styled her bangs to cover up the scars. She was now fluent in English and today was her 8th birthday which meant she was going to the zoo with Natasha. It was quiet cold this October so Tsuna was bundled up in a warm coat, a woolly hat and scarf and she was wearing the mittens her grandfather gave her.

"Come on, come on, come on! Aunt Nat, we need to go now!" Tsuna jumped up and down as she waited for Natasha to meet her at the front door.

"Alright Tsuna, I'm coming," Natasha reassures, chuckling at her enthusiasm. "The animals aren't going anywhere."

"I know, but I want to see all the animals!" Tsuna replied, throwing her arms apart at 'all.' Natasha shakes her head before taking Tsuna's hand and driving her to the zoo. "Aunt Nat, why couldn't Uncle Clint come?"

"He's busy with a mission," Natasha answers, "but don't worry, he's coming tonight with your gift."

"I don't care about the gift," Tsuna objects, "I just want to see him."

It wasn't long till they reached the zoo and Tsuna dragged Natasha all around the place trying to see every single animal in every exhibit. Tsuna was overjoyed at the day and Natasha loved seeing the pure delight in her eyes.

"He's so fluffy!" Tsuna exclaimed eagerly, referring to a bunny she was petting. They were currently in the petting zoo with other families, Natasha watched how the children all squealed over the small, cute animals when something exploded.

(BOOM!)

Everyone screamed, terrified parents grabbed their crying children before running off. Natasha immediately went to grab Tsuna but the brunette disappeared.

"Tsuna? Tsuna?!" Natasha cried, worried. Just then a voice came over the tannoy.

"Please evacuate the park. This is not a drill. A gas pipe exploded near the lion den, releasing 7 lions in total. I repeat. Please evacuate the park. This is not a drill. A gas pipe exploded near the lion den, releasing 7 lions in total."

"Oh no! No, no, no, no, no," Natasha whips out her phone to locate Tsuna's GPS signal, she found the signal instantly and ran to Tsuna's location, praying that Tsuna is kept safe.

Tsuna's P.O.V. 

I was in the rabbit's pen with the other kids, Aunt Natasha was watching me, not too far. It was amazing until there was a loud explosion.

(BOOM!)

I numbed up and was about to run to Natasha when I was swept away by the screaming adults.

"Aunt Natasha!" I cry but she couldn't hear me. I eventually manage to escape the crowd but I had no idea where I was. "Aunt Nat?" I call, hesitantly. I was getting scared, no one was here yet I feel like I'm being watched.

The hairs on the back of my neck stood up, I slowly rotate until I was facing a shrub of bushes. Something was lurking in hedge, two beady eyes glowed from within the darkness. We stare at one another when the creature pounced.

"HIIIEEE!!!!"

"Gao!"

The creature knocked me to the ground and started to luck my cheek, "Hahahahaha! Stop! It tickles!" I cry and the creature leaps of my chest, I lift myself up to see my attacker was a little lion cub.

"Hey, where did you come from, little guy?" I ask, picking up the cub. "Are you lost like me?"

"Gao!" The lion answers.

"Well don't worry, I'll help you find your family," I reassure and I get up and walk around with the cub in my arms. "I wonder what I should call you, I can't keep calling you 'little guy.' Maybe.... Natsu! Yeah, Natsu."

Natsu gives a happy, "Gao," in response. I could tell he liked the name.

"Let's go find our families, Natsu!" I announce, full of enthusiasm, marching forward with Natsu walking beside me after jumping out of my arms. I sing and Natsu joins in.

After 15 minutes of walking, I was beginning to lose hope. There was no one in site and I was beginning to get tired but I didn't give up, I promised Natsu I'd find his family and that's what I'll do!

(Crunch!)

"Is someone there?" I asked, aloud.

A man emerges from the corner, "Kid, what are you doing here? There are lions running about!" The man shouts before flinching, he yanks a gun out from boot and aims it at Natsu! "Look out!"

(Bang!)

"GAWR!" Natsu yelps in pain as the bullet hits him. He falls to the ground, the pool of blood growing larger by every passing second.

"Natsu!" I scream in fear and shock as I kneeled by his body, "Natsu, no! Don't die!"

"Rawr!" A lioness jumps out and tries to attack the man who tries to shoot her, only to discover he's run out of bullets. The man runs away, not sparing me another thought. The lioness gives chase.

Natsu can't die. I won't let him. I'll save you Natsu! The mittens glow before a bright flash engulfs the park and I was no longer wearing the mittens but a black metal-clad pair of gloves which radiates bright orange flames.

'This will help you protect the one's you love. You just need to use your dying will.'

Grandpa's words echoed in my mind. "I-I can save Natsu if... I just use my dying will," I realise. Instinctively, I close my eyes and pray hard. Please, I want to save Natsu, if he dies without me doing anything then I'll never forgive myself. Please let me save him with my dying will.

"Your wish is my command," a voice answered. My eyes snap open and I see a transparent blond man.

"Giotto-kun?" I whisper, hesitantly.

The man smiles and says, "Yes and no. I'm not the Giotto you know but that doesn't matter now. I'll help you save your friend," the man places his gloved hands on top of mine, I realise he has the same gloves as I do, and we place our hands on top of Natsu's injury.

The gloves oscillates and I open my eyes to see the orange flames become yellow. The yellow flames begins to heal Natsu's wound until it was nonexistent.

Natsu changed, his brown eyes are now the same orange as the flames and his mane of fur had become fire. "Gao!" Natsu roared, happily and rejuvenated. He's fine, thank goodness. I was about to thank the blond man when darkness envelops my vision.

The last thing I heard was Aunt Natasha's cry, "Tsuna!"

Natasha's P.O.V. 

"Come on, come on, come on. Where are you Tsuna?" I mutter, I was getting closer to her location but she was walking in the same direction so she was getting further away from me. Luckily, her little legs won't get that far.

(Bang!)

A gunshot. It was in Tsuna's direction. I sprinted to her location and saw Tsuna hovering over an injured lion cub, orange flames which turned yellow were coming out of her gloved hands. The little cub jumps up, completely fine, and Tsuna looms relieved before swaying slightly and falling to her side.

"Tsuna!" I cry out, she can't be dead. I sprint to her and was relieved to see she had only fainted. "Don't scare me like that," I scold even though she couldn't hear me and hug her tightly.

"Gao," I look over to the cub, it's mane was on fire, that wasn't normal. I need to bring this cub with me. I pick Tsuna up and the lion and run to the car. I need to get to S.H.I.E.L.D right now.
