A/N: Heya~ Are you disappointed that it is not The Case of Hibari Kyoya? XD Wah. Sorry. I'm kinda still stuck at chapter 4. So while I'm still thinking about chapter 4, this story suddenly went into my head. And for me not to forget it, I had to write this out right away though it took me quite some time since I'm kinda busy, too.

For new readers, don't worry. You don't need to read My Lover is a Doll: The Case of Hibari Kyoya for you to understand this since they are different stories (though I would be happy if you will read it :D). They just have the same concept of Doll and Master. Here, Tsuna being the master (?) and Hibari being the doll. And speaking of which, the idea of Doll and Master came from the manga, Lovers Doll, but other than that, I guess it is own.

Anyway~ hope you will enjoy and reviews are appreciated. May God be with you, bastard. :D

And about my summary. Seriously. I'm sorry. I can't think of anything that will not spoil the story. So I'm going to hold the summary for now. OTL

Warning: This story is yaoi/shounen-ai :D This is also AU. Meaning... Alternate Universe. OOCness is inevitable. Slow updates OTL. And pardon for my grammar error. And (again) rating might (not sure) go up in the future.

Genres: Romance, Supernatural, Drama, etc.

Pairings: 1827, R18 (LOL no, I'm joking XD but Reborn will be in the story. Adult form that is. XD) maybe Tsuna x Kyoko (what was Kyoko's number again? XD) or maybe not. I'm not sure anymore D:

Chapter 1: First Encounter Leaves an Inevitable Fate

"Hibari-oniichan!" An exuberant voice called making the owner of the name stop on his track. He turned his head in distrust as he immediately recognized the voice of the caller. Of course he could recognize the voice. That voice had been pestering him for about a week now.

Hibari Kyoya watched with light mounting irritation as the four-year-old Tsuna with spiky sienna hair came to his view. He was running towards him, shouting Hibari-oniichan here and there, which irritated the young raven-haired man more. He was really tempted to ignore the kid and turn on his heel but managed to refrain from doing so. That would not be polite, especially on a kid. Well hell yeah. As if Hibari could careless. But he still remained unmoved.

"What do you want?" He finally asked — not forgetting to look down since the little boy was too small to begin with — when the kid finally stopped from running and was now in front of him.

Not noticing the bitterness on his tone, the little boy replied excitedly, "Hibari-oniichan! Tsu-chan found Hibari-oniichan!" Tsuna beamed delightfully and continued, "Tsu-chan and Mama are going home from shopping then Tsu-chan spotted Hibari-oniichan! Tsu-chan is so gweat!" He giggled, jumping in happiness.

"I see." The young man replied passively and took the initiative to kneel down, meeting the little boy's cute big chocolate orbs with his ashen blue ones. "But first, I am not your brother so please," Hibari stressed the word fully, "stop calling me onii-chan." The word sounded a bit weird on his mouth. He then patted the boy's head but stopped when he noticed the previously cheerful big round eyes were now clouded with slight tears.

"B-But—But—!" Tsuna started whining, "Mama said Tsu-chan should address people with... with h-ho-hornorif—"

"Honorific." Hibari corrected impatiently.

Tsuna blushed lightly. "Y-Yeah... honorific. Mama said Tsu-chan should address them properly to show my respect."

Hibari listened with slight understanding and quietly sighed inside. He was about to reply the boy when light murmurings caught his attention. He looked around his surroundings and noticed that some people were looking suspiciously at them.

"Hey isn't that bad? Isn't that high schooler bullying the little boy?"

"Maybe we should call the police or something."

Hibari looked back at the kid and scanned him from head to toe. And from the looks of it, of course they would find them suspicious or more over, they would find him suspicious instead. The little boy was sniffing and pouting cutely (in Hibari's vision only though); it was as if he was bullying the little kid. A low growl escaped from his throat as he narrowed his eyes in agitation. Those damn herbivores.

Resisting the urge to bite those nosy people to death, he turned his attention back to the boy and his irritation miraculously disappeared. Well maybe because he couldn't fault the little boy especially when he was looking at him with those innocent eyes and pouting cutely (again in Hibari's vision only). "Then san is fine."

"Then Tsu-chan can still call your name?"

"I never said you couldn't."

Tsuna titled his head lightly as if he was thinking of something complicated before testing it for the first time. "Hibari-san..." He mumbled shyly as he felt his cheeks heating up. Then he repeated it, this time more confident and satisfied. "Hibari-san!"

Hibari scratched his head in light irritation but couldn't stop himself from smiling inside. The boy was really cute and interesting. Of course he will never admit that out aloud. "Stop calling my name for no apparent reas—" But before he could even finish what he was saying, Hibari found himself being tackled by the little boy as Tsuna wrapped his small arms around his neck. "I love Hibari-san the most!"

Hibari was taken aback slightly at the gesture but was able to composed himself in no time. "Hey, don't go suddenly shout something that embarrassing. It's disturbing." He reprimanded in a strain voice but the boy paid no heed to him as he tightened his hold against him. He let out a defeated sigh and gave in. Seriously, the boy was really a pain. And to his surprise Hibari found himself hugging back the boy in caution and — with an odd sense of déjà vu — carried him as he stood up.

But seriously, how did he end up like this again? The boy was too attached with him that it was creeping him out a little. And speaking of which, this scene feels somewhat awfully familiar. Oh yeah. It happened a week prior. His first encounter with the little boy. That fateful (?) meeting.

Hibari Kyoya was the kind of person who tended to do things on his own pace. Relying on someone was out of his vocabulary. He had no parents and grew up in an orphanage but even before he could reach adulthood, he had already left the orphanage and made a living on his own since he really doesn't like relying on someone. He doesn't give a damn to his surroundings, too. He hated crowds and most of all he hated weak herbivores who couldn't even defend themselves. In other words he was a loner. So he couldn't understand himself why he went the trouble of helping the damn brat at that time.

x x x

He was going home from his school when his attention was caught by a hysteric cry of a child as he was passing by a local playground on his way. As if on impulse his head automatically shot to the direction where he heard the cry and his eyes met an annoying sight. There was indeed a child crying and in front of the child was a suspicious man who was, from the looks of it, forcing the little kid to come with him.

"C'mon little boy, this ossan will take you home. I'm gonna buy you candy so come with me now."

"N-No! Tsu-chan doesn't wanna! Mama! Mama! Tsu-chan wanna go home!" The little boy, Tsu-chan, cried as he tried wriggling free from the scary grasp of the stranger.

Hibari watched the scene in annoyance and disgust. He wanted to pretend he didn't see anything and go on but... ugh. Indeed he said he hated weak herbivores the most but he hated even more those damn herbivores that have the nerve to take advantage against those weak ones. Before he could stop himself Hibari strolled forward the two, a displeased scowl present on his face.

"Tsk. What a difficult kid. I said you're coming with me!" The suspicious man barked and started dragging the kid, ignoring his cries and protest but before he could even move a step forward, he was halted by the presence of an unknown intruder.

"Let go of the kid." Hibari demanded dangerously, looking at the stranger menacingly.

The suspicious man blinked in confusion before glaring at the newcomer. "W-Who are you? I'm this boy's father so don't get in our way!"

"N-No! You're not Tsu-chan's Papa!" Tsuna intervened between his cries and shook furiously his captured hand. "Let Tsu-chan go!"

"S-Shut up!"

Hibari walked closer and chuckled with no humor, "It seems what you just said and the kid's doesn't match at all." He mocked as he glared at him. "Let go of the kid before I do something you might regret later."

"Che," The stranger released Tsu-chan's arm in a non-gentle manner and faced the young man with a fierce expression. "Then I'll just teach you a lesson you troublesome meddler!" He shot forward his fist in attempt to strike the raven-haired young man but even before he could land a blow, Hibari already beat him into it. He dodged the attack effortlessly and prepared his own counter attack. "Too slow damn herbivore." Not bothering to use his hands, Hibari kicked the suspicious man straight hard into the stomach which sent him flying backwards and fell unconscious to the ground.

"Pathetic herbivore." Hibari muttered to himself as he tapped his right foot on the ground as if shrugging off imaginary dirt from his shoes. Satisfied he turned back his attention to the little kid and he couldn't help but arching an eyebrow.

The boy was frozen stiff, staring at him widely. Hibari couldn't quite shake the feeling off that there was something wrong. Worried that the kid might have been traumatized by the scene just now, he walked closer to him and knelt down to his level, his ashen blue ones meeting curious ones. But before he could voice his thoughts two small arms came flying around his neck as the little boy practically attacked him by hugging him. Instead of the expected hysteric cries and pleas, the boy surprised him by giggling and chuckling. "So cool! So cool!"

Hibari broke the contact and pushed lightly the boy away from him. "Aren't you scared?" He asked curiously, eyes twitching when the boy just kept staring at him with pure and earnest eyes. "Well?"

Tsu-chan shook his head slowly, cheeks warming up. "No. Onii-chan was so cool! Tsu-chan is not scared!" He proclaimed proudly as he spread his arms in the air.

Hoh. Hibari smirked. So the boy got some spunk after all. "How old are you?"

Tsu-chan grinned and beamed confidently as he gestured his age through his fingers. "Tsu-chan is four already!"

"I see." Hibari deadpanned, ignoring that the kid just gestured three of his fingers albeit that the kid said he was four. So he wasn't really sure which of it was true. He doesn't care anyway though.

So what now? Now that the troublesome thing had been taken care of, maybe it's time for him to leave as well. After all getting involved more will be quite a pain. So should he leave the kid alone then? Speaking of which, why was a kid like him all alone in such a place? Did he get lost or something? "By the way, why are you here all alone? Did you get separated from your parents or what?"

At the mention of his parents, Tsu-chan's previously perky chocolate orbs watered suddenly as if something clicked at the back of his mind. "T-T-Tsu-chan wanna go home! Mama! Papa! Where are you? Tsu-chan wanna go home!" He burst out crying, his excitement while ago was now forgotten.

Hibari heaved an irritated sigh. He knew this would come anyway. So the kid was really lost. He take back what he had said earlier. The kid was really a weak herbivore.

"Shut up. Quit your yapping." He scolded solemnly, satisfied when the boy conceded. "Give me your backpack." He instructed referring to the small knapsack that the little boy was carrying. Well all kids carry a nametag or something on their knapsacks right? The boy might have the needed information. Hopefully.

Obediently, Tsu-chan handed his red knapsack to Hibari, still sniffing quietly.

He took it with no word and began inspecting the bag. As if his wish was granted, Hibari found the needed item in the side of the bag; a makeshift keychain of a nametag with the needed information. It read:

Name: Sawada Tsunayoshi (Nickname: Tsuna)

Age: 4 years old

Address: #xxx xxx St., Namimori Town

Contact Number: 092166199xx / xxx-xx-xx

Hibari read with interest as the content registered on his mind. So the kid's name was Sawada Tsunayoshi. What a herbivorous name. Especially the nickname. It really suited the kid. And the kid was actually four years old. Maybe the kid was just dumb. Well that aside, now that he already got the needed information he guessed he couldn't do anything about it now. He looked back at the boy and shrugged his shoulders, handing him back his knapsack. "Come on. I'll take you home."

He could just call the contact number but since the address was coincidentally near to his apartment, he guessed he could just walk the boy home personally.

Tsu-chan, whose name was actually Tsuna, blinked innocently. "R-Really?"

"What, you don't trust me?"

Tsuna shook his head. "No. Tsu-chan trust onii-chan!" Once more, Tsuna's little arms captured Hibari's neck and giggled. "Onii-chan is so kind!"

Hibari snorted at the praise. He was not really that kind of person. He was just doing this out of... duty? Responsibility? Pity? Hmmph. Either way he doesn't really care. He hugged back the boy and carried him as he stood up. "You really shouldn't trust strangers so easily, stupid herbivore."

But Tsuna just kept smiling, happy that somehow he managed to make a friend... probably.

After a quiet fifteen minute walk, Hibari found himself in front of a fairly normal household. It seems familiar but he doesn't really remember. Maybe he passed by this house before since, after all, they have the same street. He read the name, checking if it was the right place. Sawada.

"I guess you're home now." He put the boy down and turned on his heel as if he was ready to flee any moment now, not bothering to bid goodbye.

Tsuna panicked when he saw the high schooler prepared to leave. He can't leave yet! He hasn't thanked him yet! He doesn't even know his name! "W-Wait! O-Onii-cha—" Tsuna tried to run after him but his voice was muffled as his face met the concrete ground.

Hibari halted. He can already tell what just happened. He wanted to ignore him but his feet were betraying him. He turned around, annoyed. "What now?" He watched as the boy slowly stood up from tripping and began crying. Here they go again.

Against his own will Hibari went towards the little boy and looked down at him, crossing his arms. "What, did that really hurt?" He asked in a sarcastic tone.

Tsuna stopped and started shaking his head furiously. "It's because onii-chan is leaving already. Tsu-chan hasn't even thanked onii-chan! Tsu-chan doesn't even know onii-chan's name!"

Hibari massaged his temple and rolled his eyes. "Seriously, you're such a pain." He took a handkerchief from his pocket and knelt down as he shoved it to the boy's forehead. "It's bleeding slightly. You should take care of that first." He ordered and continued, "And my name is Hibari Kyoya. You don't need to thank me either. I did this on my own accord." He stated, hoping the kid would just agree without arguing back.

Luckily, Tsuna seems to understand his unspoken wish and nodded quietly as he shyly took the hankerchief. "Okay..."

"Tsu-kun?"

Two heads moved at the call in reflex as a young woman with brown hair walked out of the house, eyes widening.

"Mama!" Tsuna cried in happiness, running towards her and hugged her dearly.

Hibari immediately stood up and cursed inside. He really didn't want to meet the mother, too. Meeting the mother would mean questions. And he really didn't need that at the moment.

"Oh Tsu-kun! Where have you been? Mama and Papa have been looking for you! We were so worried!" Tsuna's mother cried, relief all over in her voice and carried her son. "Papa is still out looking for you— Ara? What happened to your forehead?"

"Tsu-chan is sowwy. Tsu-chan tripped but Hibari-oniichan lent me his hankie." Tsuna admitted sheepishly, moving his attention at the said teen.

"Hibari-oniichan?" As if it was not enough, Tsuna's mother asked curiously, shifting her gaze from her son to the raven-haired boy in front of them.

Hibare glared at Tsuna who dared to mention his name. He was just about to flee since the mother hasn't seemed to notice his presence yet but the damn herbivore just made unnecessary things more complicated. And what's with the name? Hibari-oniichan? He almost gagged at the call.

"Oh my! I'm sorry! I didn't notice you before... I was so worried with Tsu-kun that— Oh! Are you, by any chance, was the one who brought my boy back home?" The young woman gasped and took Hibari's hand eagerly with her left hand since the other was occupied. "Oh! Thank you very much! Thank you! I just took my eyes off of him for a second when we were out shopping awhile ago then he just disappeared all of a sudden! Tsu-kun is so hopeless." She admitted sheepishly and giggled, "By the way, my name is Sawada Nana. You can just call me Nana~! And this boy is Sawada Tsunayoshi. But I bet you already know that. How about you? What's your name?" She asked enthusiastically, feeling already attached to the raven-haired boy.

"...Hibari Kyoya." Was all he could mutter. The woman was really talkative wasn't she? So talkative that he found himself getting a little bit annoyed but at the same time amused, too. "Well no, actually I just found him—"

"Ah! Mama! Don't bully Hibari-oniichan!" Tsuna suddenly interrupted as he struggled against his mother's hold. "Put Tsu-chan down."

Tilting her head slightly, Nana did what was asked, feeling a bit confused.

"Who's getting bullied, herbivore?" Hibari said in a bored tone as he watched the little boy tugged quietly his pants and looked up at him, his finger on his lips.

Hibari lifted an eyebrow. Was he telling him to keep quiet? Is that why he interrupted him awhile ago? He doesn't want to worry his parents? Hibari smirked. The kid was really interesting. Maybe he was smart after all.

"Tsu-kun? What's wrong?" Nana asked curiously.

Tsuna turned his head and smiled brightly. "Nothing!"

Nana seems to accept that when an idea struck her head. "Why don't we invite Hibari-kun for dinner tonight instead? Isn't that a nice idea Tsu-kun?" She exclaimed gleefully as she looked over between Hibari and Tsuna.

"Yay! Tsu-chan want that, too!"

Hibari forced a cough getting their attention. The conversation was progressing without his consent. There was no way he would welcome the offer from the person he just met. That would be too weird. His meeting with the kid was just a mere coincidence. He shouldn't get himself too involved with them.

"I am grateful for the offer but I need to pass. I'm actually about to go home now. I apologize, Sawada-san." He bowed his head slightly, using her last name instead despite she told him to call her Nana.

Tsuna pouted as Nana let out a small awww then smiled in understanding. "I guess it can't be help. Maybe next time then~!" She winked at him and pushed Tsuna lightly towards the teen. "Go say goodbye and thank you to your onii-chan."

Tsuna fidgeted as he looked up at Hibari, embarrassed. "T-Thank you... Hibari-oniichan..." His words were almost a whisper that Tsuna doubt Hibari had heard him. Tsuna puffed his cheeks. Why can't he make his voice louder? "A-Ah... Hibari-oniichan thank—"

But Hibari just nodded and already turned his back on him. Tsuna's heart sank. Is that it? Will this be their last meeting? The thought didn't sit well with him. He just managed to make a friend! Hibari-oniichan was his first friend (Hibari doesn't think so though). Without thinking he ran after him as he tried his best not to trip and mustered all of his strength to call after him, gripping tightly the handkerchief on his hands. "W-Wait! Hibari-oniichan!" He panted lightly, happy when the lad reciprocated the call by stopping and turning his head to his direction. "Hibari-oniichan! W-Will you play with Tsu-chan again?"

Hibari was about to ignore the kid but seemed to think better of it. He heaved a long sigh and inclined his hand up ahead. "My apartment is two blocks away from here. Right at the first corner." And with that he left with no more ado.

Tsuna's mouth turned into a frown. What did Hibari just say? He didn't understand what he meant! Panicking, he was about to chase after the young man when a light weight touched his shoulders surprising him. He turned and saw his mother smiling.

"Oh Tsu-kun~ Hibari-kun just told you where he lives! What a shy boy he is~!" Nana giggled as she carried her son on her arms. "I know where his apartment is. After all it's the only apartment around this area and it's not really far away from here. And if I'm not mistaken, Ishikawa-san is the landlord there. So let's pay him a visit next time. Sounds good?" She offered with a bright smile as they went back inside their house.

Tsuna nodded happily. "Un!"

Meanwhile, Hibari paused on his way and looked back at the direction where he had last seen the kid though he wasn't there anymore. He just contradicted what he had said earlier didn't he? But the kid was far more interesting than he initially thought. It would kill his boredom at the moment. Hibari shook his head and let out a satisfied sigh as he continued on his path. He didn't know, however, at that time that this will lead to the prologue of his inevitable fate.

A/N: So chapter 1 is done! And it's much longer than my usual chapters! Yay?

Actually I already have this chapter 1 kinda long time ago but I just managed to finish typing it out yesterday. You see, when I'm writing a story, I always first write it down on my notebook before I type it out on my PC. IDK, I can't seem to write well when I'm in front of the computer. AND DAMN! I had to type this ALL OVER AGAIN because the damn computer suddenly stopped responding and I had to restart it. I wasn't able to recover the file though. T^T

Anyway! What do you think of this chapter? Eheh~ Oh yeah. Please don't think of Hibari as a Lolicon, Shotacon, Polygon (LOL Gin-san? XD) or whatever. I have a reason why I made Tsuna's age around 4 and Hibari's age around a normal high schooler. And I bet you're also wondering WHERE the HELL is the DOLL and MASTER concept in this story. Muahah~ if you're curious, then stay tune for the next chapters. I'm already starting writing chapter 2 but hmm... oh well. Unlike The Case of Hibari Kyoya, I already have a plot for this story and ending as well. Yeah seriously. But that would take a long time. I guess. You see, in The Case of Hibari Kyoya, I decided to change the plot again for some reasons, that's why I haven't updated chapter 4. I think it's much more complicated than the first plot that I thought.

Well, again. Pardon for my grammar error /wrong spelling (if there is) T^T. And this story is AU okay. And of course the story will not start all fluffy. Haha~ and though this is The Case of Sawada Tsunayoshi, I'm writing it in Hibari's point of view. Hehe. Well writing it in Tsuna's POV as a child is too weird. But don't worry, when Tsuna grows up I'm gonna switch it into Tsuna's POV. Err. I hope so. Haha~

Ah! About Tsuna's contact number. Hoho. That was actually my cellphone number before. XD ignore the xxx just think of any number street or something.

Okay. This is getting longer. I will REALLY appreciate it if you will LEAVE A REVIEW. Critiques are fine but please no FLAMING. I'm a sensitive person. I take things to heart. Seriously. I encountered one in The Case of Hibari Kyoya (though not really a flame but whatever). And it made me feel less motivated. XD But nah. I'm still gonna continue writing it! Okay~

See ya next chapter!

RANDOM SPAM (You can ignore this one):

WAAAAH! Damn. I'm so happy! I finally got Akuno Meshitukai Face (again) in TinierMe! :D Now I only need 8 Eyes to complete all of the Vocaloid Eyes! Yush~

And damn. I really love Niizuma Eiji! GYAAAAAAAA! XD So cool! I wanna read the next chapter of Bakuman T^T

Okay that was so random XD

FACT: I came up with the title of this story from Lovers Doll (which became My Lover is a Doll) and Sekaiichi Hatsukoi (The World's Best First Love: The Case of Onodera Ritsu) haha. That gave me an idea that I should make a different story of Hibari and Tsuna... and thus, it became My Lover is a Doll: The Case of Hibari Kyoya/Sawada Tsunayoshi. :D
