Chapter 4: The Sun Arcobaleno! And the Storm!

"VOOOOIII! WHERE THE FUCK HAVE YOU BEEN, YOU SHITTY BOSS!?"

Xanxus ignored the silver-haired man and went straight to his room, locking the door behind him. He threw his jacket on the bed and grabbed a bottle of rum, drinking straight from the bottle, he sat on the bed with his back resting on the headboard, a smirk slowly spreading across his face as he remembered his parting with a certain Sky.

"You're a horrible, horrible person."

Xanxus scoffed, "You're just figuring that out now?" He ignored the glare the girl sent him. Shrugging his shirt on, he turned to her and watched blankly as she made her way towards him, fully dressed, much to his disappointment.

"You could have at least held back you know. My whole body hurts," she complained, pouting at the man as she stopped in front of him and began buttoning his shirt, smirking when he lazily wrapped an arm around her waist.

Matching her smirk, he said, "You weren't complaining last night, and you were certainly not complaining 15 minutes ago when I was banging you against that tree."

Tsuki's face flushed, "Stronzo," she mumbled. Where the hell did he get all those stamina? Doing it from midnight till dawn, and in all those position. This guy really is a monster.

Xanxus grabbed her chin and tilted her head, leaning down, he whispered against her lips, "Admit it, you enjoyed being fucked by me just as much as I enjoyed fucking you. You were just as insatiable as I was, Vasílissa."

The younger Sky grumbled into the kiss, pulling back slightly, she stared at him in the eyes and reminded, "This changes nothing."

Red eyes glared at her, "That's not something you need to remind me of."

"Good." She attempted to pull away from him but the arm around her waist prevented her, she looked up, confused, "Xanxus…?"

He smirked down on her and purred, "You want to stop this?"

She pretended to think about it. Smiling at the man, she wrapped an arm around his neck, fingers toying with the collar of his shirt, "Nope. At least, not yet. This is far too pleasurable," the girl admitted with a wicked glint in her eyes.

Xanxus grinned wildly, "You and I are going to have a lot of fun."

Tsuki sighed in relief when she didn't see Reborn in her room, opening her window, she entered the room and went straight to her closet to grab a change of clothes before making her way to the bathroom for a much needed shower.

"You reek of sex… and Xanxus."

Tsuki froze. Damn it.

Standing beside the doorway of her room was her tutor, eyes hidden by his fedora, but the boss candidate heard the disapproval in his tone.

"Reborn…"

"What were you thinking, Dame-Tsuki? Or were you even thinking at all?"

Tsuki closed her eyes and sighed, "It's not like you didn't see this coming. You knew there was something going on between Xanxus and I, and yet you chose not to say anything about it."

Reborn looked up and met his student's eyes, "Hn. I didn't think you'd be foolish enough to act on it."

She shrugged her shoulder in reply, "This thing with him was too tempting. I couldn't resist," and with that, she walked pass the hitman and continued her way to the bathroom, only to stop before she could take a step down the stairs. "What happened between us doesn't change the fact that we're enemies, that he would kill me and my friends if he was given a chance. I know that, he knows that. I swear, whatever happens between us from this moment on until the end of this Ring Battle…" she turned her head and looked straight into the eyes of her tutor, "it's not going to get in my way."

"Hmph. You were smart enough to use protection, right?"

Sunset-amber eyes flashed with mischief, making Reborn's eyes narrow dangerously, "Dame-Tsuki…"

Tsuki chuckled at the warning look on the infant's face, "We did it raw…" she ducked down to avoid the bullet her tutor fired at her, sweat dropping when she turned and saw the hole the bullet made, "are you trying to kill me?"

"Dame-Tsuki, tell me you're joking, or I swear the next bullet will go straight to your skull."

Tsuki raised an eyebrow at him, "If you kill me, you'll have to deal with my Guardians, a retired hitman, the Cavallone Family because let's face it, Dino-nii loves me more than he fears you, then there's Vongola cause you know, you killed one of their boss candidate… do you really want to deal with all that?"

Reborn smirked, "You've gotten cheekier, Dame-Tsuki."

She shrugged, "You know I'm right."

Looking at her tutor with a serious look on her face, she told him, "We did do it raw, we were both too caught up to even think about using protection, but…" she patted her right arm, "I have implant, Reborn. Stop worrying about this thing with Xanxus. I know what I'm doing."

Reborn watched his student leave, thinking about what she just said. Why and when did you get the implant, Dame-Tsuki? Was it before I came here? Or have you been planning this thing with Xanxus from the very start? He gritted his teeth, irritated with the fact that there were still a lot of mysteries surrounding his student, things that he didn't know, plans that he didn't know. She never talked about what her life was like before she met him, no matter how much he threatened her, she was tight-lipped, even her Guardians. All he knew was that when he met her, she was the exact opposite of what that Baka-Iemitsu told him.

A year and a half ago

The number one hitman in the world waited for the door to open, mentally preparing himself for when he meets his next Dame-student, but judging from what the CEDEF Boss told him, it looks like this one will be even more challenging to train than his previous student. It's nothing I can't fix. Be prepared, Dame-Tsuki.

The door opened and revealed a woman with short brown hair with matching brown eyes, she looked around confusedly for a second before Reborn coughed to get her attention.

"Ara. Where did you come from? Are you lost?"

"Ciaossu. I am the home tutor, Reborn."

Nana blinked, "Home tutor…?" she cocked her head to the side in confusion before remembering the flyer she received earlier, "Ah! I remember now! So you were the home tutor that flyer mentioned. Let's go inside."

Reborn followed the woman inside her home, nodding to himself as he looked around the cozy looking home. When they entered the kitchen, Nana immediately grabbed some cushion to make it easier for him to see the table. He thanked the woman and hopped into his sit.

"So where is my student? Is she still sleeping?" Reborn asked, eager to start his job. He figured, the sooner they start, the faster it will be for his student to come to terms with the fact that she will be the next boss of the most powerful Mafia Family in the world.

"Hmm? Tsu-chan is still sleeping, she usually wakes up an hour before school starts," the woman informed him, placing a cup of tea in front of him.

"Grazie."

Nana took a sit in front of him and drank from her own tea, "E to… Reborn-chan… I think there was some sort of mistake."

Reborn raised an eyebrow, "What do you mean, Sawada-san?"

"Tsu-chan doesn't need a home tutor, she's really intelligent you know. I thought the flyer earlier was just an advertisement, but seeing that you're here... I wonder who called you…"

He stared at her for a minute, seeing the genuine look on her face proved that she wasn't just trying to make excuses for her child.

"Intelligent?"

Nana nodded, pride shining in her eyes, "My Tsu-chan is a prodigy. She's the top of her class and she's really popular too. Lots of guys want her to be their girlfriend, but Take-kun, Mu-kun, Kyo-kun, Ryo-kun, and Tsuyoshi-san are so overprotective of her, they always scare off anyone who attempted to court her. At this rate, I won't even get a single grandchild," the woman pouted.

If Reborn was any other person, his jaw would have been hanging open, but since he was the world's greatest hitman, he kept his expression in check but on the inside, he was mentally killing the idiota. The more he listened to the woman's bragging about her child, the more the hitman was tempted to fly back to Italy just so he could kill the idiot whose information about his own daughter was so damn inaccurate—he might as well have been talking about someone else's kid. Reborn would have doubted the woman's words, but since he personally knew Iemitsu, he knew just how badly the guy sucks at being a father, but even he didn't think that Iemitsu would be this wrong about his own child. Some bits of inexact details like friends and grades, he could understand, but being this wrong. Iemitsu… what the hell is wrong with you.

"Ah! Tsu-chan, you're awake. Let me fix your breakfast."

Reborn turned the direction of the kitchen door where his student(?) was standing, eyeing him. And this time, he couldn't stop himself from gawking even if he tried. Throughout his entire life—especially before he became an Arcobaleno—he's met countless of gorgeous women, women whose main weapon were their beauty, but the girl standing in front of him, she was in a league of her own.

"Let me guess, Iemitsu sent you? Wait—no, that's not right, he wouldn't even have the time to send his Dame-daughter a home tutor, now would he? So this must be Nono's idea, right?"

Seeing the look on her face when she mentioned her father and the fact that she called Nono, Nono, made Reborn realize how utterly, utterly wrong everything was. He expected to meet a student far worse than Dino, and yet, he met a girl who looks like she knows far more than what she should, he expected an average looking girl but instead, he met a goddess who looks like she's well aware of how much her looks, affects those around her, and that glint in her eyes...

Iemitsu… just how badly did you fucked up.

Keeping his expression neutral, Reborn regarded his student, "Ciaossu. I'm Reborn, your home tutor."

The girl smirked, mirth shining in her sunset-amber eyes, "I don't need one."

She turned to her mother without waiting for the hitman to reply, "Kaa-san, can you tell Takeshi to come to my room when he gets here. Looks like Reborn and I have a lot of things to discuss."

Nana tilted her head to the side in puzzlement, "You want a home tutor, Tsu-chan?"

"Nope," her daughter quipped, "but he seems interesting, so I'm keeping him for a bit."

Reborn's eyes narrowed dangerously.

"Hmm, ok, but where would he sleep, though? Mu-kun, Ken-kun, and Chi-kun are using our guest rooms… maybe we could ask Tsuyoshi to take him in, his flyer said that he'll tutor you for free in exchange for food and a place to stay."

Tsuki shrugged, "He could stay in my room."

Nana blinked, "Eh? But he's a boy… I don't think they'll be happy about this..." she trailed off worriedly.

Reborn watched as the girl's entire personality changed from being hostile to being warm.

"Don't worry about it, Kaa-san. He's an infant, I'm sure my chastity is safe," she giggled when her mother gave her a deadpanned look. She walked towards her and gave her a peck on the cheek, "Kaa-san, it's fine. I'll talk to them about this, okay?"

Nana sighed, "Alright, Tsu-chan. You win."

Her daughter grinned at her cheekily, "Don't I always?"

Reborn's eyes softened as he watched the interaction between mother and daughter, his expression went back to being impassive when the girl turned to look at him.

"Come on."

He let the girl pick him up and carry him to her room, jumping out of her arms as soon as the door closed.

"Who are you?"

Tsuki rolled her eyes, she sat on her bed and gave the hitman an amused look, "Sawada Tsukiyomi. Didn't Iemitsu tell you that?"

"Hmph. You are nothing like the daughter he mentioned. I'm just making sure."

Tsuki threw her head back and laughed, shaking her head, she gave the hitman a genuine smile, "I like you. And since I like you, I'm going to let you in on something… I know a lot of things, Reborn, even things that I shouldn't. You were right when you said I wasn't the girl that guy mentioned. The daughter he mentioned was the daughter he thinks he has, the daughter he chose to believe he has. Dame, stupid, clueless… but I'm not that girl…"

Onyx eyes locked with sunset-amber ones, "Then… who are you?"

The girl smirked, and the hitman, for the first time in his life, felt a chill ran up his spine.

"Stick around, Sun Arcobaleno. And maybe you'll find out."

In the nurse office of Namimori Chuu, a certain Storm Guardian just finished folding the last paper airplane he needed for his training. He turned to look at his tutor sleeping on one of the beds and woke him up.

"Oi! Shamal, wake up! I'm done."

"Hm?"

Shamal groggily sat up, staring at him in confusion, "Ah, you folded all paper into paper planes… what the heck are you doing?"

"Wha—!? Of course it's for training! You told me we would complete the new move!" Gokudera exclaimed, glaring angrily at the laid-back man.

"Hm? Ah, you don't need to fold any more paper planes," the man informed him offhandedly.

"What!?"

Shamal ruffled his hair, "What I mean by 'complete' is—it had a good effect already."

The Storm Guardian stared at him, stupefied, "Oi… matte! But I didn't even bring down one paper plane!"

"You still don't understand. Like I said! Strong willpower wouldn't mean so much from now on. It's the same thing with hitting on a girl," the older man explained.

Gokudera stared at him. He's talking nonsense again…

"Hey, do you know what the most important thing is when flirting?" the doctor asked with a teasing glint in his eyes.

Gokudera swallowed nervously, cheeks turning red as he avoided Shamal's eyes and mumbled, "Uh… well… eroticism?"

Shamal sweat dropped at the kid's naivety, "You really are a middle-schooler"—and you even have that goddess for a boss, such a waste. He let out a deep sigh, "It can't be helped. Look, it's here, here," he said, tapping his temple.

"To put it plainly, those guys that are unpopular did not use their brains enough. If you just use your brain and pull some tricks, there isn't a woman in this world that won't fall for it."

Gokudera stared blankly at him. Too confident.

"Now that you understand, use your brain and write it down, don't fold paper planes anymore."

The teen slammed his fist on the desk angrily, "Can't you just get straight to the point and teach me!"

Shamal looked away, a look of amusement on his face, "There he goes again. Even if I knew the answer, I still wouldn't tell you how."

"Why!?"

"In the world you live in, only those who find their own way to survive can do so."

Gokudera gritted his teeth angrily, "Oi Teme! Stop with all your wisdom already! I don't have the time to be playing mind games with you! My match is tonight!"

"Ah, that's right. Tonight is your match, but… as long as that move isn't complete, I won't let you got to the match."

The Storm stared at him in shock, "What?"

Shamal sighed, he rested his cheek on his palm and stared at his student with a serious look on his face, "You're aware, right? That out of all Tsuki-chan's Guardians—not including the cow-child—you're the weakest."

Gokudera glared venomously at the older man.

"All of them have mastery over their Flames and an advance control over it, for their age anyway. The Rain and Cloud can infuse their Flames on their weapons, the Sun can release his in his punches, the Mist can create real illusions, and you, you could barely control yours, let alone use it for combat. And you claim to be her right-hand man, who are you trying to kid, Hayato? Do you even know what kind of a right-hand man she needs and wants?"

The kid was looking down, Shamal couldn't see his expression, but he can see the way he was clenching his fists. Maybe I went too far…

"Don't you think I know that…?" Hayato muttered, "Even now… I still don't know why she chose someone like me to be one of her Guardians… why she's giving me a chance to be her right-hand when she already has someone who's more competent than me… but…"

A year and a half ago

"We have a new transfer student who was studying overseas in Italy, Gokudera Hayato."

The silver-haired teen looked around, searching for the girl who was supposed to lead the most powerful Famiglia in the world, eyes narrowing when he didn't see her.

That's weird... she should be in class right now…

He was so focused on searching for her, he didn't notice a certain baseball ace staring at him.

When the bell rang and the girl has yet to show herself, Gokudera left the room without giving the girls who flocked him any attention. Grumbling to himself, he made his way to the back of the school and pulled out a cigarette, grabbing his phone from his pocket after lighting the stick.

"Haha. Kyoya will not be happy if he sees you smoking in school."

Gokudera turned to the direction of the voice, glaring at the teen smiling at him, "The fuck do you want?"

The black-haired teen continued to smile, "Nothing much. I just wanted to meet the new transfer student. Ah—that's right, I haven't introduced myself yet. Yamamoto Takeshi."

His smile didn't waver even when the other teen continued to glare venomously at him.

"Oi Teme, do you have a death wish? Fucking scram already! Or else I'll blow you up. I'm already in a bad moon since that bitch didn't show up, so I suggest you leave before I vent my anger out on you."

The Italian felt his blood ran cold, looking at the smiling teen from the corner of his eyes, he swallowed nervously, feeling the tip of the blade graze the skin on his throat after the slight movement.

"I suggest you watch what you say about her from here on out… we don't take kindly to people who insult our Sky."

The words were spoken casually, but Gokudera heard the unmistakable threat in his tone.

"Takeshi."

The blade was gone from his throat in an instant.

"Gomen, Tsuki."

Tsuki stared at the Italian with an unreadable look on her face before her attention went to the person sitting on the windowsill of the school, "A friend of yours?"

"Hmph. You came earlier than expected, Gokudera Hayato," Reborn turned to his student, "he's a member of the family I called over from Italy. It's my first time meeting him as well, though."

Gokudera stared at the hitman in awe, "So you're the world's number one hitman, Reborn."

Tsuki and Takeshi raised an eyebrow at the comment.

"You're not kidding about me becoming a candidate for the successor if I kill Sawada, right?"

Takeshi's eyes narrowed dangerously, he let out his killing intent and warned the teen, "I wouldn't try that if I were you."

Reborn and Gokudera felt the intensity of his aura, the hitman's killer instinct warning him to stay clear of the kid while the silver-haired teen had to clench his fists tightly to stop them from shaking.

Tsuki sighed, "Takeshi."

Said teen turned to her with a slight pout, "But Tsuki, he said he wants to kill you. Was I supposed to just take that lying down? At least I warned him, those two would have killed him instantly," he pointed out, grinning when his best friend just rolled her eyes at him in reply.

Tsuki turned to her tutor, a look of disapproval on her face, "You shouldn't have lied to him like that, Reborn."

Reborn lowered the tip of his fedora to his eyes.

"I get that you want me to start gathering my Guardians, but didn't I already tell you to let me handle that. Whose bright idea was this? Yours or his?"

Tsuki didn't wait for a reply, turning her attention to the Italian watching her, she gave him an apologetic look, "Warui. Reborn lied to you. Even if you managed to kill me, you're just going to die yourself, either by the hands of my friends, or by the hands of Vongola since you killed their last remaining legitimate heir. But if you want, I'll fight you, here and now."

Gokudera was lost for words, he didn't know how he was supposed to answer that. When the hitman called him and asked him to come to Japan to test the strength of Vongola's successor, he immediately agreed to do it, especially after he found out that the heir was the same age as him—and a girl to boot. He thought it was going to be easy since she was raised as a civilian, but now that he's face to face with her, he didn't know what to do.

Tsuki raised an eyebrow when the teen continued to stare at her, "You don't want to?"

Gokudera looked down in discomfort, "A-Actually… I never had the desire to become Vongola Decimo… I just wanted to see if the successor has the strength to become a suitable boss…"

"And? Did I meet your expectation?"

A small smile made its way to his face, "You're much more than I expected actually. I don't need to fight you to know how strong you are. I already lost before the match even started."

"Hahahahaahaha."

Both teen turned to look at the black-haired teen clutching his stomach, tears of laughter in his eyes.

The silver-haired teen gritted his teeth in annoyance, "Oi! What the hell are you laughing at!?"

Yamamoto looked at him, laughter still in his eyes, "Gomen, gomen. It's just that… Tsuki was right, you'll fit right in."

Reborn and Gokudera's eyes widened in shock.

"W-What?" The teen turned to look at the girl, who was looking at the amused ace with a fond expression on her face. He suddenly felt a sense of longing for someone to look at him the same way, to have the same kind of bond the two teens have with each other.

"Oi, Dame-Tsuki. What's he talking about?"

Reborn's question brought him out of his reverie, remembering what the other teen said, he also turned to the girl in confusion while trying to stop the flicker of hope from showing in his eyes.

"Hm? Oh, that's right."

Gokudera felt his whole body freeze when she turned to look at him with the same fond look on her face.

"Smokin' Bomb Hayato—iie, Gokudera Hayato, how would you like to be my Storm Guardian?"

Tsuki's eyes softened when the Italian fell to his knees, staring up at her with wonder in his eyes. She walked towards him and ruffled his hair.

"Honestly, I was planning on taking you with us when we went to Italy a couple of years ago, but at that time you were still training with Shamal and you still lived with your family, and even after I found out that you ran away from home, it was around the time Federico was missing, security was tight in Italy and I couldn't risk Iemitsu finding out about..." she ignored the look Reborn was giving her, sunset-brown eyes not breaking away from shock green eyes. "I figured with Federico most likely dead, it would only be a matter of time before they decide to name me heir, so all I had to do was wait for Iemitsu—or the tutor they hire—to call and bring you here."

Gokudera felt his cheeks flushed when the girl smiled at him.

"So what do you say? Want to join my family?"

A wide grin made its way to Tsuki's face when the Italian bowed his head.

"I would be honored, Juudaime."

When the teen looked up, for a brief moment, his eyes flashed red, "I refuse to fail her or the family she welcomed me into."

"Yo."

Tsuki smiled, but then she noticed that a certain teen was missing, "Where's Hayato?"

Mukuro raised an eyebrow, "Oya? I thought he'd be with you."

"Hn. I saw him leave the school with that herbivore doctor earlier."

"Maybe he was stopped by Shamal," Reborn suggested from his perch on Takeshi's shoulder, "it's impossible for Shamal to let his disciple enter a battle if there's no chance of winning."

"Does that mean his new move isn't complete yet?" Ryohei questioned.

"Probably."

Tsuki sighed, "Let's just wait for him inside."

Xanxus was leaning against the window with his arms crossed, eyes closed as he waited in boredom for her to arrive while ignoring the glances his second-in-command was sending him. He felt her presence before anything else, his eyes opened and immediately sought hers, smirking when he saw the flirty gleam in her eyes.

Four people witnessed the brief exchange between the two bosses.

Mukuro and Kyoya shared a look.

Kufufufufu. So that explains why her skin looks shinier than normal… you are in so much trouble, Hime-sama.

Reborn sighed.

Squalo's jaw dropped when he reached the same conclusion as Mukuro. You've gotta be fucking shitting me!

"So today's match is indoors…" Kyoya muttered, eyes narrowing when he realize how much damage his school was going to get.

"Tako-head isn't here yet… what the heck is he doing?" Ryohei grumbled.

"He'll come for sure," Takeshi said confidently.

Tsuki suddenly remembered something, she looked up and asked her Rain, "How did it go with Oyaji?"

The tall teen smiled, "Everything went well… he wants to talk to us and Mama, though. Does Mama know already?"

Tsuki nodded, "Aa. I went to the hospital this morning and told her everything. Oyaji was there too so they probably talked already... lunch tomorrow?"

Her Guardians nodded in agreement.

"It seems like his opponent hasn't come," Mammon voiced.

"Voi! Did he wuss out?"

Belphegor chuckled amusedly, "What's the point of running? When they lose the Ring Conflict, they'll all die anyway."

The Cervello exchanged looks, "When the clock strikes 11, Gokudera Hayato will be disqualified and Belphegor will win by default."

Both sides turned to the clock and saw that there was only 10 seconds left before 11 o'clock.

Ryohei's brows furrowed, "Not good…"

Tsuki bit her lip, watching the seconds tick by before sighing in relief when she heard the familiar sound of dynamite being thrown.

The clock exploded 2 seconds before the awaited time, Tsuki and her Guardians turned to the direction of where the dynamite came from and saw the Storm Guardian breathing heavily.

"Sorry to keep you waiting, Juudaime "

Takeshi smirked, "You came."

Belphegor chuckled maniacally.

"Gokudera Hayato has arrived!" the Storm declared.

Stronzo – Asshole
