WARNING FOR THIS CHAPTER: Tsuna having a *ahem* interesting dream that most teenage boys are prone to have.

Lips parted and small gasps of pleasure escaped them each time slim fingers touched a certain part of his body. Pale cheeks flushed with an alluring red made his eyes look like he was pleading for the other to touch his body moremoremore.

The slim fingers rose to touch those apple-red cheeks, delighting in the way his partners eyes fluttered and long lashes brushed the tip of his finger.

So perfect...

He bent down and tasted the skin of his partner, humming when a slight whimper responded in a way that sent heat surging through his body. Slowly he started to travel down the body underneath him making sure to make it very obvious that the other was already taken. He nipped the skin teasingly right where the skin vanished underneath the dark pants that were just begging to be ripped off.

"Mmm..."

He lifted his eyes when he realized that the sound was slightly muffled to look up at the trembling figure, a smile forming on his face at the sight. Dark hair clung to his partners face and equally dark eyes peered down at him with a vulnerable expression that no one but him would be allowed to see.

A chuckle escaped his mouth as he took in the hand covering his partners mouth.

Mine.

Crawling back up the body underneath him gracefully, he pressed forward so his mouth rested just beside an ear. "No need to hold it back, I want to hear you scream Haru-"

"-ka!" Tsuna bolted upright in his bed, sweat trailing down his face and breath coming out in harsh pants. Fire raced in his veins and he felt vaugly uncomfortable down there.

What in the world did he just dream about? His voice had sounded different, a smooth monotone that was different then his usual tone. And Haruka...

He gulped at the though of his best friend, the sudden image from his dream coming to the fore-front of his mind. Would he really look like that when-

Click

Slowly the brunet turned toward the threatening aura his face paling and body temperature dropping as he came face to face with a familiar green gun.

Dark eyes shadowed by the tip of a fedora glared threateningly into what felt like his very soul.

"Dame-Tsuna, you dare..."

He gulped and a bead of nervous sweat trailed down his temple. How did he know everything?

"I can read your mind. Don't think I'll allow you to live another second when your thinking pervert thoughts about my son Hentai-Tsuna."

A loud 'HIIIEEE!' followed by a booming gunshot echoed through the Sawada household making Nana pause at making breakfast and look curiously up toward the sound. Shaking her head at the rough housing her son was doing with his tutor she smiled and continued with the meal. Sounds like Tsu-kun is having fun.

Ermes was perplexed. He had finally located Trident Shamal after days of searching high and low for him in every single town only to find the rumored play-boy living with a woman and a child.

Perched in a tree far from the household looking through a pair of goggles, because the woman was scary good at sensing his presence, he tried to figure out why in the world the doctor was playing house. Mafioso's didn't just settle, after being surrounded by action all the time usually they would be too paranoid to stay in one place all the time and just stop.

Especially Shamal, he wasn't known as a play boy for nothing after all.

So why?

Slightly irritated but mostly perplexed Ermes watched as the woman chatted with Shamal in a friendly manner while the kid was shooting paper airplanes with a squirt gun of all things. He analyzed the kids features for anything that resembled the doctors since there was a good chance that the kid was Shamal's...son?

Poor kid, the Rain Guardian mused after finally realizing that the kid was indeed a boy. He must get lots of people confused with his looks, but Ermes could already see that the kid was going to be a looker when he got older.

In fact the kid would undoubtedly rival his looks. The Number One Hitman was known for his irresistible 'Mafia Seduction', as the Hitman called it, that could bring any gender to their knees begging to be taken.

...

Ermes paused and scanned the kid again.

Dread coiled in his gut.

Pitch black spiked hair? Check.

Irresistible looks that could send anyone to their knees. Check.

His fingers started to shake as he griped the binoculars, coal black eyes that seemed to look into your very soul...Check.

Pushing down the minor panic attack that was threatening to rise Ermes set down his binoculars and stared at the house that was containing someone potentially dangerous.

The Number One Hitman, The Harbinger of Chaos, The Sun Arcobaleno had a son.

With a deadly shot that never missed and skills to outmatch even the most experienced Mafioso Reborn wasn't someone to mess with. Like all the other Acrobaleno he was allied with the Vongola making the Famiglia immensely powerful and near unstoppable. Insignificant families, such as his own unfortunately, didn't even hold a chance to go against the Vongola. Not only did they have hundreds of Mafioso under their command, and quite a few strong Famiglia, but they also had Seven power houses as their Guardians and seven more monster power houses better known as the Acrobaleno.

No one had thought that the Acrobaleno could breed, they were toddlers for goodness sake. But now...now everything had changed.

One of the monster power houses had a child.

From what he had seen the child was trained with the gun already, that meant they were more than likely preparing him for the dangers of being a Mafioso. Based on what he had seen the kid was going to be as good as his father, if not better, the kid had two guns just like Xanxus which made him shiver in fear.

He really hoped the kid wouldn't turn out as violent as Xanxus.

Was this the reason Shamal had suddenly vanished? To train The Number One Hitman's son?

His boss would have to be informed of what he had just realized, since it could affect everyone in a potentially bad way. Right now though, he had to approach Shamal without bringing any attention to himself so the doctor could cure his boss.

...

...

At around midnight he wasn't too surprised when Shamal stepped outside and approached the tree he was perched in. As expected from Trident Shamal.

"What do you want?"

He hopped down from the tree and gave the doctor a polite nod. "My boss is sick-"

"No."

Ermes blinked at the reply and narrowed his eyes slightly. "You didn't even let me finish, she's a woman so-"

Shamal stuffed his hands in his trench coat. "No."

Slightly pissed and a little nervous, because his boss would be in trouble if Shamal wouldn't help, Ermes sent the doctor a sharp glare. "Why? You're a doctor, that what you do right? Cure people."

Brown eyes looked with his own making his anger falter slightly. Hidden within the casual presence he could see a predator stirring.

How did the proverb go? Right...Wake not a sleeping lion.

Ermes could hold his own in a fight, but against Trident Shamal who fought with Mosquitos and could give him a dangerous disease he knew he was at a disadvantage. But his boss, her weak body flashed in his mind and his determination hardened.

Lion or not his boss needed help and Shamal was the only one who could help them. "I know who the kid is." He finally spoke watching as the doctors eyes flash dangerously a the threat. "I'm sure everyone would be interested to hear what The Number One Hitman has been up to."

It happed before he could blink, a distinct sense of falling registered and the pain of his head hitting the ground made him grunt in pain. Dazedly he turned his gaze to stare at the foot that was keeping him on the ground and watched as lightning sparked from the appendage. What? Shamal didn't have the LightningFlame...

He slowly looked up until he was staring at the figure of the woman he had seen in the house. Her body was outlined by the light of the moon which would have made her look rather eye-catching if it wasn't for the killing intent pouring out of her in waves. He hadn't even sensed her...

Dark brown eyes glared down at him and long hair twirled as a breeze blew past. "I'll kill you before you can even take a step."

Ermes gulped Goosebumps rising along his arm as he took in the Lightning sparking around the woman's form.

"Kimiko." Shamal soothed slightly flinching as the burning gaze was turned his direction. "His disappearance will arose questions and his Famigila will send out scouts to see what happened."

The woman, who he now knew was named Kimiko, scoffed but the killing intent lessened considerably and he was able to breath again. "He threatened my baby."

"I know."

They both looked down at him thoughtfully as if determining what they where going to do with him, Ermes hoped that they would do the sensible thing and let him leave but you never really knew with the Mafia. Besides he had seen what women could do, especially when protecting their children.

"I guess I have no choice but to go." Shamal finally stated his shoulders slumping. "But only if you promise not to tell anyone if I do help your boss." He continued sending Ermes a threatening look that made the blonde nod instantly.

Kimiko snorted and finally took her foot off of his body and he immeditaly got off the ground sending the woman a cautious glance. He knew now that it was a bad idea to underestimate her, he had thought she was just a normal woman and had been proven wrong the hard way.

"I won't tell anyone outside of my Famigila about your son." He promised. "But I have to tell my boss."

He held back a flinch when lightening sparked Kimiko's direction but the woman didn't attack him again. His boss was, well his boss she wouldn't be very happy if she realized he hadn't told her about the Hitman's son. In fact she would probably rip him a new one and he didn't really feel like being sent through a wall, again.

Shamal sighed and ran a hand through his hair. "That's understandable." He replied and sent Ermes a threatening look. "But if you tell anyone else I'll give you Testicular torsion."

Erme's felt a shiver of fear rock his body and he quickly nodded suddenly feeling the need to protect his family jewels.

Madness. It was utter madness.

Bombs exploded, missiles were launched and knives were thrown.

The objective was simple, run for your life.

The only thing I was slightly curious about what where in the world Hibari was through all this mess. Because I was certain he would do a lot more then bite us to death if he knew what was going on in his precious school. Perhaps Reborn was able to occupy him?

Tsuna 'Hiieed' as a bomb exploded so close to us we were nearly knocked off of our feet. I quickly regained my footing and raced alongside Yamamoto who was having a little too much fun.

"This is so fun." The baseball player commented cheerfully as if to prove my thoughts. "These toys are really realistic!"

I still was astounded by his obliviousness, he and Nana could compete to see who was the most oblivious. But then again he had a certain look in his eye that I had seen on his face when playing baseball so he was also taking this seriously.

"How can you think that?!" Tsuna exclaimed as we dogged some bullets shot toward our direction.

"Don't question his logic Tsuna." I replied my brow twitching when I heard the distinct sound of Lambo's voice somewhere within the chaos.

Dark clouds suddenly started covering the otherwise beautiful blue sky and thunder rumbled in the distance. Great, now the real shit was about to go down. I grabbed Tsuna's hand, a squeak coming from him as I started to fasten our pace. Lambo must have brought his fifteen year old self out to play the 'game.'

"THUNDER SET!"

I risked a glance over my shoulder and slightly paled when I saw bombs, lightning enhanced missiles and bullets coming our direction. I knew that it wasn't time for anyone to die yet so we weren't in any mortal danger, but seeing something like that wasn't good for my soul.

Tsunayoshi's 'HIIIIEEEEE' nearly shattered my ear drums when he realized the danger we were in and even Yamamoto seemed slightly frightened.

I grabbed Tsuna's body and yanked us to the side ignoring the way he yelped and covered his body with my own. I didn't think, I just reacted.

He stared up at me with wide brown eyes and I closed my eyes and smirked at him slightly in response.

Then the ground exploded and a hand grabbed the back of my jacket. I stumbled slightly and felt my world tip as I was suddenly picked up and hung over something hard, my hearing disappeared and dirt flew up into my face as everything exploded.

Whoever was carrying me effortlessly dodged and ran through the battle field, dragging a panicking Tsuna along with them as they sprinted forward.

Eventually everything calmed down and I was able to comprehend what was going on. "Phew, that was close." I stared at the white shirt in front of my face slightly amused as the carefree sound of Yamamoto's voice reached my ears.

"Y-yamamoto pulled us o-out and saved us." Tsuna commented in a shaky voice, I raised my head to give the slightly battered brunet a glance to make sure he wasn't harmed. Besides being emotionally scarred he wasn't missing anything important so that was good.

Eventually I was set down and I nodded to the baseball player in thanks and slight respect. He simply smiled cheerfully as if he was at an amusement park and we didn't almost get killed.

"You passed the test. You're officially part of the family." Reborn acknowledged and Yamamoto grinned happily.

"Thanks!"

Gokudera stomped toward Yamamoto and grabbed him by the front of his shirt his eyes shadowed. Instead of yelling and cursing he looked into the baseball players eyes with slight respect."Good job. You protected the tenth so I have no choice but to accept you into the family." He let go of the other students shirt and took a few steps back. "But I'm Juudaime's right arm, you're the shoulder blade."

Yamamoto stared at him slightly surprised at the sudden personality change. "Sh-shoulder blade?" Then a bright smile appeared on his face and he wrapped and arm around the bomber laughing happily. "I thought so before, but you're a funny guy!"

Of course, I mentally rolled my eyes, Yamamoto is Yamamoto after all.

Suddenly his eyes grew slightly serious. "But I don't want to withdraw from being Tsuna's right arm." He replied. "So you can be the ear lobe."

Gokudera looked pissed. "The fuck?! Then you're a nose hair!"

I snorted in amusement and watched next to a horrified Tsuna as the two started to bicker, in a funny way they were sort of getting along.

"Looks like you have more competition Haruka." Reborn commented idly and hopped onto my shoulder. "You better be prepared."

I sent the Hitman a slightly confused look.

He smirked. "You have the best chance of being Dame-Tsuna's right hand man since you've known him the longest. You should go defend your place."

Like heck. I didn't even want to be in the Mafia to begin with, but obviously it was too late to get out now. Especially since Reborn had already decided that I would be in Tsunayoshi's family for me. "I'm Tsuna's shadow." I replied quietly so that Tsuna wouldn't be able to hear me. "Gokudera can be his right hand man."

Reborn sent me an approving glance.

In a sense being a 'shadow' was even a higher rank then being a right hand man. The stronger the light, the darker the shadow.

"It's so hot." Tsuna complained blocking his face from the bright sun. "It's making me really thirsty."

I nodded in agreement wiping my sweaty brow and wrinkling my nose in distaste. I hated the heat.

We both turned when a ringing sounded behind us and I blinked in slight shock when I recognized who was coming toward us on a bike. Tsuna gazed at her in slight confusion as she stopped a few feet away from us and took of her helmet. Red hair gleamed in the sunlight and I mentally wondered how in the world she was surviving this heat wearing leather pants of all things.

She reached in the basket attached to her bike while switching her attention toward me, and promptly froze.

I rose a brow.

A light shade of pink enveloped her cheeks and suddenly she was flying toward me with open arms. "Wha-" I exclaimed and stepped back in slight fear but couldn't escape her as she promptly embraced me and I was suffocated by her large chest.

"Reborn~ You look so handsome~"

"Ah! Haruka!" Tsuna shouted as the woman cooed and nearly strangled me with her death grip.

I struggled slightly mentally cursing the Hitman. Why was she even attracted to him anyway? He was a baby for goodness sake! "Please let me go." My voice was muffled as she nuzzled my hair in adoration. "I'm not Reborn."

She paused and I was pushed back slightly so she could get a better look at me, I pressed my glasses back up, Shamal had gotten me a new pair before leaving, and met her eyes with a blank face.

It took a moment but I watched as her green eyes widened in surprise and her mouth opened and closed in response. "You-"

I rose a brow.

Before I could say anything she was suddenly on the bike and peddling who-knows-where, leaving me and a very confused Tsuna watching her.

He glanced at me in slight worry. "Are you okay Haruka? That woman was really strange..."

I nodded and picked up the bag of groceries I had dropped. "Yes, she just took me by surprise." I wondered what she would do now, I knew that she had been Reborn's lover but would that change since I was here? I didn't think it was too important but I knew she was a helpful addition to the family either way.

Honestly I didn't even know.

Eventually we made it back to Tsunayoshi's house and the brunet was able to ask Reborn who the red-headed woman was.

"Bianchi is a former fellow Hitman." The baby stated bluntly.

Tsuna gaped. "Wha-"

Ding dong

He furrowed his brow in confusion and headed out of his room to answer the door glancing over his shoulder at me when I didn't follow. I got up and trotted after him in response to the look, might as well save him from the dangerous woman who was trying to kill him I guess.

I followed Tsuna as he walked down the stairs to answer the door, not really surprised when Bianchi was there with a pizza in her hands. This time she was wearing a leather skirt, she must have gotten hot after all and changed.

"Thanks for waiting." She said with a slight smile. "A delivery of Vongola pizza."

Tsuna's eyes widened at the sight of her, knowing she was dangerous thanks to Reborn's explanation. "You're the woman from earlier!"

When she put on the gas mask I quickly grabbed Tsunayoshi by the arm and dragged him into the kitchen. "Haruka? What are you doing?" He asked looking up at me in confusion.

I peered around the wall and stared at Bianchi who was looking our direction, or my direction really, in slight surprise. I narrowed my eyes but didn't do anything, I actually had no clue why I reacted like that in the first place.

Reborn appearance made her instantly change demeanors and her eyes filled with adoration as she stared down at the Hitman. "Reborn."

"Ciaossu Bianchi."

Tears started to build in her eyes. "I'm here to bring you back, let's do another big job together reborn."

"Eh?" Tsuna tugged on my sleeve and I turned back to look at him. "What is she talking about Haruka?"

I shrugged my shoulders. "Reborn said she was a Hitman right? They were probably partners in crime or something." I replied watching as Bianchi tried to talk Reborn into coming back with her. Not that it would work, but I was curious to see how he would interact with her.

"I have to raise Dame-Tsuna," Reborn stated ignoring her tears. "And my son."

I paused. I was added in the equation?

Bianchi froze and her gaze turned to me, I merely stared back apathetically. Something flashed in her eyes, jealously I assumed, and her lips pursed.

"So he's your son? I thought he looked familiar." She shuddered at a aura of depression surrounded her body. "I could you cheat on me Reborn? I thought we were in love!"

Reborn wasn't affected in the least. "I didn't cheat, Kimiko was my third lover who I thought died. She didn't and now I have a son."

"Reborn has had lovers?!" Tsuna exclaimed in disbelief. "He's just a baby!"

"I see." Bianchi replied. For a moment I thought she was going to go away but suddenly and air of determination and what looked like flames surrounded her. "I won't lose! Just watch Reborn!"

She was suddenly gone as soon as she had appeared leaving Tsunayoshi confused and me slightly dreading what the future could be. She was probably going to try to kill me too so that meant I would have to watch what I ate for a while.

Ugh.

She tried many times to 'get rid' of Tsunayoshi and I, of course it never worked and more times then not I had to snatch something poisonous out of his hand before Tsuna ate it. The whole rice ball moment was crazed and full of yelling and Tsuna running around in his boxers.

I felt slightly bad that he had to eat all of the bad rice balls thought, that couldn't have been good for his stomach. Finally though everything settled down and for a moment I thought it would be peaceful for a while.

"Haruka?"

I sent the brunet a sideways glance.

"Hmm?"

Tsunayoshi fidgeted with his fingers for a moment before finally straightening and taking a deep breath. "C-could you by chance make some rice balls?"

I furrowed my brow in slight confusion. "Why?"

He turned slightly pink and stuttered. "I-I was just, um...frightened." He nodded to himself. "I was frightened that Bianchi would poison my lunch again so..."

I shrugged my shoulders. "Sure I can ask my mother."

Much to my confusion his shoulders slumped in defeat. "Thanks..."

Odd kid.

AN: Hope you enjoyed it so far! Sorry for any mistakes and tell me what you thought. :)
