Author's note: Wow, two years… I guess I was on hiatus huh?

And I can't apologize enough for that! *Slams head onto the floor* Gah! And I promised I wouldn't be that type of author!

I'm SORRY! Man, I'm soooooooo SORRY!

Well as you know, I got this inspiration from a book I was reading. That book ended quickly and I wasn't satisfied with the ending, my inspiration just got flushed down the drain. So yeah, sorry again!

Anyway, now that this chapter is out of my system, I can go redo the next chapter of Parallel to His Heart. I've been getting a lot of request for that one lately. Heh, by the way there is this one fic that was inspired by my Parallel to His heart and it's 1827 and it's 5 chapters long but it has like a hundred reviews!

Gah, 8027 I swear I'll make you more popular!

So back to this topic: 8027.

Last year I made a Christmas Challenge for writers to write an 8027 Christmas fic and I'm thinking of doing it again this year! I hope more people will participate this time! Last year was a lot of fun! The Challenge will be given on December 1 so that you have twenty-five days to finish it! Yep, the deadline of the fic will be on Christmas day! YEHEY!

So yeah, I guess that's all the announcements from me. Other announcements will be at the bottom! I hope you enjoy reading this chapter. Sorry for any grammatical mistakes or misspells, the spellchecker wasn't on while I was typing.

Oh yeah, sorry about the lame title… My creative juices were low! (Sugar please!)

Chapter 18

Che cosa sei?

(What Are You?)

Yamamoto had once a distant memory about being left alone in the park once in December. He was invited by his friends to play outside but his father was worried that the snow outside would get worse and forbid him. Since he was only five and he didn't know what 'obedience' meant, the young raven-haired boy snuck out and headed to the park.

To his chagrin, his playmates weren't there, having been forbidden by their parents as well, and the young boy found himself alone in the cold park.

He didn't want to go home. What would his father say to him when he found out he snuck out?

He was going to get angry for sure. And for Yamamoto, staying outside with the pretty snow or face his father's wrath... well, the choice between which of the two was obvious. He had walked towards a bench and sat there.

It was the coldest and loneliest feeling he had ever felt in life.

Well, until now that is...

Have you ever felt something cold was crawling under your skin, freezing even your blood and slowly making its way up your spine?

The sensation Yamamoto felt at that moment, as he was lying on some cold stone, and the mist surrounding him, suffocating him, drawing out his breaths in cold puffs...

It was a painful feeling. It was like he was trapped beneath a frozen lake trying to get free, slamming his fists on the cold surface defiantly but knowing at the back of his mind that it was useless... he was drowning, and no one knew where he was... no one would hear him scream...

...Was he going to die?

"Hm, it seems like his body can't take the demonic atmosphere of our base." Birds stated as he kicked the writhing boy lightly on the side. The teen trembled and shivered and his fists clenched at the feeling.

"Oh my, you bought home a pathetic present, Birds." A girl's voice suddenly made herself known behind the old man. "What's the use of bringing that here if it's going to die anyway?" She flipped her hair. "It'll just be another mess to clean up."

"Oh my dear M.M." Birds laughed creepily. "It was just a mere bonus. He knew the angel prince and I thought: Oh my, what an interesting human."

"He knew the prince?" M.M. stated and she leaned down to look at Yamamoto's face. "Oh, he is quite handsome." She tilted the baseball star's face and looked at it in all angles. "Now this is a face I can use for money."

"Not so fast M.M., that person is a present for me I believe." A cold tone suddenly echoed throughout the dark space. M.M. immediately let go of Yamamoto's face and stepped back as mist formed in front of her slowly shaping into a young teen.

A strange teenage boy with a weird hairstyle smiled down at the fallen human before him. "Ah, humanity in it's rightful place. What a wonderful present my Birds."

"I am glad you are pleased Mukuro-sama." He said as he inclined his head slightly. M.M puffed her cheeks in annoyance and looked away.

Mukuro smiled as he leaned down, extending a gloved hand towards Yamamoto. His heterochromatic eyes began to glow red and blue as he neared the human-

WHOOSH!

A blinding light suddenly enveloped the dark room. Mukuro pulled back, stunned, as M.M. squealed at the burning feeling in her eyes. Birds howled and tripped onto his back while the twins had long diappeared leaving behind a sulfuric scent.

The light continued to blind them and Mukuro could only step back shielding his eyes. Gradually the light vbegan to dim and in its place laid Yamamoto looking more peaceful.

"W-What was that?" M.M asked ina high pitched tone as she rubbed her eyes in irritation. Birds was still howling in pain at the light while Mukuro looked down at Yamamoto with pursed lips.

"My, how interesting. That was no ordinary light." Mukuro stated and he reached ot once again.

"Be carefuly Mukuro-sama!" M.M. stated but a strange violet mist- demon aura- had surrounded the teen's hand as he reached out. There was a momentary spark and Mukuro flinched a bit, but he was able to breach through the light that surrounded Yamamoto.

His heterochromatic eyes glowed once more and his hand went to Yamamoto's pocket and pulled out something white and soft.

"That's-!" M.M gasped and Birds, who had ceased his howling sat up, stared at what made M.M so surprised.

Mukuro sneered in disgust as he stared at the pure white feather on his hand. "How disgusting. An angel's feather...? What a surpising human we have in our possession."

Birds sat up, regaining himself as he adjusted his glasses. "But this doesn't seem to belong to a mere guardian angel Mukuro-sama."

"What are you saying Birds?" Mukuro crushed the feather in his hand. "Are you saying one of those stuck-up high and mighty angels actually took a liking to a mere human?"

"It happens often." Birds stated.

"Then he is no longer an angel. He is a fallen one." Mukuro stated and the feather in his hand bursts into flames. "No Birds, I don't think your assumption is entirely correct. If he is a fallen, then his feather wouldn't look like this. I think there is a much more complex idea behind this."

"Hn, either way, that angel- whoever he is- will be heading this way soon. If it's true that this human is important to him then…" M.M. licked her lips maliciously. "We'll have a guest arriving soon."

"Seems so." Mukuro stated with an evil smile.

"Oi Dame-Tsuna!" A powerful whack to the head was what woke up the sleeping Vongola Angel.

"Itte! Reborn! What was that for?" The brunet winced as he rubbed his head and looked at his tutor who was frowning down at him.

"Haven't you been listening to what I've been saying to you?" And Tsuna squeaked at the evil look in the arobaleno's eyes.

"U-Uhm, g-guardian angels?" Tsuna said and he covered his face preparing for a beating.

But surprisingly nothing came. The brunet peered over his hands nervously. Reborn was looking at him as though he was disappointed that missed a chance at hitting his student. The young heir sweatdropped.

"That's not entirely incorrect." Reborn stated as he pointed his Leon-stick at the board where there was a chart of a guardian angel. "We were talking about the special powers of a guardian angel. The healing powers, the powers of intervention, and dreams."

Tsuna tilted his head at the last phrase. "Dreams?"

"Ah, it's the power of the senses. It lets you know your charge is in trouble through your dreams… But if you're awake, it gives you visions…" Reborn stated and he smirked. "It's very useful."

"A-Ah." Tsuna stated with a nod.

"Do you know why I'm telling you this Dame-Tsuna?" Reborn stated as he fully faced his student and Tsuna's back straightened as he tried to look for an answer in his head.

"To help m-me as the tenth heir? Since all knowledge is required f-for t-this p-position-"

WHAM!

Tsuna squeaked but Reborn had a thoughtful look on his face.

"Although that information isn't incorrect, you have to dig deeper than that to get the real answer, my stupid student." The sun arcobaleno stated as he began to tap his leon-stick lightly on the table.

"D-Dig?"

"Tell me, do you remember being here before you fell asleep?"

"H-Huh?"

"Time's running out Dame-Tsuna. What is your intuition telling you?" Reborn stated a quite serious look on his face. Tsuna's eyes widened as he began to do what Reborn said and he began to think.

A flash of someone's face passed before the brunet's vision.

"A boy." Tsuna began to say unconsciously. "A teenage boy. He's the same age as me."

"What does he look like?"

"Tanned skin, tall, dark-hair…" The brunet began to mumble and like a puzzle piece the picture of a young teenager formed in his mind.

This was…

"Who is he?"

"Y-Yamamoto Takeshi?" Tsuna whispered and his eyes slowly began to widen. "M-My charge."

"And where is he right now?"

"H-He's supposed to be with me." Tsuna said, panic creeping in his voice. "We're in an ice cream shop somewhere in Namimori… D-Did I fall asleep? Am I dreaming?"

"Focus! Where is he?" Reborn said firmly and Tsuna shifted a confused gaze at his tutor.

"I told you! He's with m-me-" But then Tsuna's eyes wqidened in horror. "U-Unless-"

"Dame-Tsuna, where is he? Where is your charge?" Rbeorn demanded and Tsuna stood up, staring at the 'dream' Reborn.

"Reborn, what do you mean? What are you telling me? Yamamoto's not with me? But where? How?" Tsuna felt a cold feeling run down his spine. "I have to wake up." He realized.

"Where is he now Dame-Tsuna?" Reborn continued to ask him, black eyes serious, freezing Tsuna in the spot. "Where?"

"I-I-" Tsuna gulped a she held his head. "I don't-"

"WHERE?"

CRASH!

Brown eyes widened when the whole scene of Reborn shouting at him began to break in front of him likeglass. Suddenly he was in a dark void with no light.

"This place is…?" Tsuna said looking around in confusion. He extended his wings, letting its pure white color shine some light unto the darkness.

Ah, it's the power of the senses. It lets you know your charge is in trouble through your dreams…

Tsuna turned abruptly when he saw something move at the corner of his eyes. Something blue… Like a life aura…

"Tsuna…"

Brown eyes widened and a bright orange flame appearted on Tsuna's hand as he tried to shed light on the place he heard the voice from. "Yamamoto?"

No answer.

The angel frowned and he stepped forward trying to catch a glimpes of something, but it was just too dark to see anything-

"Kufufufu…"

"What was that?" Tsuna asked out loud, his voice echoing through the void. Something blue flashed at the corner of his eyes again.

"Ahahaha!" A familiar laugh rang out through the void. Although that laugh usually brought a sense of peace and calm in Tsuna, right now it made him shiver since it sounded unnaturally loud and creepy in the dark space.

"Y-Yamamoto?" Tsuna squinted his eyes and the place he had been looking at began to be enveloped by blue flames. Tsuna's eyes widened and he let out a relieved sigh when he saw Yamamoto in the middle of that blue life flame, smiling at him.

Tsuna took a step forward, a smile on his face. "Your safe-!"

Not yet.

Tsuna's eyes widened when mist began to envelop the blue flame, slowly turning the pure blue into tainted violet. Yamamoto's eyes slowly began to close.

Tsuna reached out. "Y-Yama-"

Don't take a step further.

Tsuna froze, being forced to watch as his charge's life flame was enveloped by unpure violet. Yamamoto's body began to sink into the darkness, little by little parts of him were beginning to disappear.

Those are demon flames. It'll consume any life aura near it.

"NO! YAMAMOTO!" Tsuna shouted, ignoring the voice warning him against what he was about to do. The only thing in his mind was that he won't let Yamamoto vanish without a trace! He wouldn't let the boy fall into darkness!

He will save Yamamoto! Just like how he saved him when he fell off that building-

This is different.

The voice. It sounded like stopped in his spot. An invisible force was holding him down.

This isn't as simple as saving someone from falling off a building Dame-Tsuna.

Then what do I do?

"What should I do Reborn?" Tsuna said in a distressed tone. His legs were refusing to move forward. Tears were gathering in his eyes. "How can I save Yamamoto?"

First you have to calm down. Your charge won't go down so easily.

And true enough, the moment Reborn said that, a light shone through Yamamoto's body, stopping the darkness from devouring him any further. A small object on his charge's hand kept him safe.

"T-That's…" Tsuna said as he squinted and his eyes widened. "My feather."

He is fighting too. And as his guardian angel, you can't lose.

"A-Ah." Tsuna sniffled as he rubbed his eyes. "So what's the plan?"

Dame-Tsuna, I didn't show you this dream just to tell you how Yamamoto is faring right now. The purpose of this dream is for you to gather information.

You have to hurry though. It won't be long before the demon after Yamamoto's sould intercepts you.

"Y-yes." Tsuna said and he closed his eyes as he tried to concentrate. Almost at once, a rush of information entered the brunet's mind.

The scent of something old, musty… an abandoned building? A factory?

An image of old rides and old theaters appeared in the brunet's head…

…An abandoned amusement park?

WHAM!

Time's up. I wish you luck Dame-Tsuna.

"Tsuna…"

Kufufufufu….

"Sawada-dono! Sawada-dono!" A voice woke up tsuna from his not-so-good nap. Brown eyes looked up in slight confusion at worried blue eyes. Suddenly the worry registered in Tsuna's mind and the brunet stood up, surprising the External Vongola angel.

"Basil-kun!" Tsuna stated out of breath. "This is bad! We've got to hurry!"

"E-Eh? D-Don't tell me Sawada-dono has also heard?" Basil stated shocked.

"Heard? Heard what?" Tsuna asked as he looked at the angel. He wasn't unaware of the strange looks he was getting. Because you see, Basil was in angel form so no one could see him, so right now, it looked like Tsuna was talking with a tree.

"Fuuta de la Stella-dono, the angel ranking prince, has been kidnapped by demons!" Basil said and a bad feeling settled in the brunet's stomach.

"K-Kidnapped…?" He stated in shock. But he left the kid with Hibari! He should be more than safe! But… kidnapped? How did that happen? "B-But Hibari-san was s-supposed to…"

A flashback of Fuuta waving at him as he ran to catch-up with Yamamoto flashed in his mind.

Tsuna clenched his fist. He should've escorted Fuuta to Hibari's office first. B-But-! Yamamoto was acting strange and he was already ahead of Tsuna so…!

Still! Tsuna should've checked on Fuuta when Yamamoto was home safely!

Argh! This is all his fault!

Yamamoto's disappearance, Fuuta's kidnapping!

It was because he was too naïve and foolish! He wasn't careful enough!

"Sawada-dono." Basil placed a hand on the tense shoulders. "Please calm down, this isn't the time to be blaming yourself." Basil stated and his eyes shone in pure seriousness. "We should direct all our energy into finding Fuuta-dono instead."

Tsuna's eyes flashed helplessly at Basil's face. "B-But I can't!"

Basil blinked in surprise. "What? But this is a red alert! All the angels near the vincity are given strict orders to-!"

"Yamamoto's missing!" Tsuna blurted out in absolute panic. "I… I can't abandon him! He's my charge!"

Basil's hand fell from Tsuna's shoulde rin shock. "Yamamoto-dono is…?"

"It's my fault! I-I was so tired… I fell asleep and he must;'ve wondered off somewhere!" Tsuna stated trembling.

"How are you sure he didn't just go the bathroom?" Basil asked the young heir.

"I saw him just now in my dream." Tsuna said tiredly. "You know, the power of a guardian angel to sense when his charge is in danger? The power of senses?"

"Y-Yes…"

"Yamamoto's life aura was being consumed by a demon. It isn't just any ordinary demon too." Tsna's eyes flashed orange for a second and Basil stepped back at the aura the other suddenly let out. Nearby humans felt their hair stand up at the sudden atmosphere. "It was a powerful demon, he pushed me out of my own dream befor I could gather too much information on their whereabouts."

"But you know where they are?" Basil asked as he approached Tsuna nervously.

"A-Ah, I think so." Tsuna's eyes shadowed and Basil nodded in understanding.

"I understand Sawada-dono. Please look for Yamamoto-dono instead." Basil stated and Tsuna looked up shocked.

"E-Eh?"

"I will personally see to the search party of Fuuta-dono. You can concentrate on finding Yamamoto-dono before it's too late." Basil nodded and Tsuna gaped at him.

"But Basil-kun-!"

"It's an order." Basil said firmly but then he smiled. "Besides, right now you're a guardian angel and basically I'm your superior, so you have to follow my orders, if that's okay?" He added the last part nervously.

Tsuna blinked and a small smile relaxed into his face. "Ah, that's fine. Thank you Basil-kun."

The brown-haired Italian smiled at the young boss-in-training. "I wish you luck Sawada-dono. Please save Yamamoto-dono." Basil patted the other on the shoulder before he unfurled his wings and flew off.

Tsuna watched his friend fly off and a serious expression settle don hi9s face just as a hand settle don his shoulder.

"Uhm, excuse me sir… Are you alright? You seem to be talking to yourself…" A concerned civilian asked and Tsuna turned to face him with a serious face that made the poor man nervous.

"I'm fine." Tsuna stated in a monotone voice and he easily felt himself slip into his inner dying will. "That aside, can I ask you a question?"

"H-Hai?"

"Do you know of any abandoned amusement parks nearby?"

"It's noisy outside." Hibari grunted as his vice president Kusakabe came in to deliver him reports. The vice president rose an eyebrow at this queer statement. Noisy? What did his president mean? There were no classes, and as far as he knew there was no one withing ten feet of Namimori.

"Uhm are you alright president?" Kusakabe asked and Hibari turned to him with his usual blank look.

"Why do you ask?" Hibari stated and Kusakabe gulped.

"It's just that, there isn't anything outside that's creating noise at all." Kusakabe said and then he thought, Except birds... But I'm sure that's not what the president means.

"Oh right. You can't see them can you?" Hibari stated as he looked out of his window and a question mark floated above Kusakabe's head.

"See what?" Kusakabe asked but Hibari didn't answer and he continued to look outside.

Right now, he could see several angels coming out of their pretense of living a normal human life and going about noisily, trying to communicate with other angels. It was easy to spot them among the huan beings… I mean, the wings on their backs were a huge giveaway… And also, they were invisible to most humans. So… if they ran in the middle of the street, no truck would honk on them at all.

Because, again, they are invisible to human beings.

Hibari's eyebrows rose however when he saw a bleached-head, tanned teen stop jogging outside his school to stare at a random angel flying across the sky.

Oh, how interesting. Was that kid not human then?

"Kusakabe…" Hibari motioned his subordinate who walked to his side. "Tell me, can you see that tanned kid wearing a jogging attire."

Kusakabe looked at what his president was pointing at and nodded. "Yes. Why do you ask president?"

"Who is he?" Hiabri asked and Kusakabe squinted his eyes to see better.

"Ah, that's Sasagawa Ryohei, the captain of the boxing club." Kusakabe stated.

So, he's a student of my school. Hibari thought in interest. "Sasagawa, why does that name sound fmailiar?" Wasn't there a girl with the same last name?

"Yes." Kusakabe said as though he was answering Hibari's unasked question. "He is the sibling of the school idol Sasagawa Kyoko."

Sasagawa Kyoko? Hibari thought and he remembered the girl he ran into once yesterday. She seemed normal. They're siblings?

"Are they half-siblings or is one of them adopted?" Hibari asked.

"Yes, they are half-siblings." Kusakabe confirmed and he turned his questioning gaze to the disciplinary president. "Why do you ask, president?"

Hibari pointed his tonfas at the vice president, successfully keeping him quiet. "No questions. I am merely curious regarding the students of my school."

"H-Hai…" Kusakabe said. Satisified, Hibari turned his weapon away eliciting a sigh of relief from his subordinate.

"Anyway Kusakabe, why don't you go up to the roof and get rid of the nuisance currently staying there?" Hibari stated as he sat back down on his chair.

"Nuisance?" Last time Kusakabe patrolled, there was no one on the roof at all.

"Yes, nuisance. A nuisance going by the name of Gokudera Hayato." Hibari stated coolly. Kusakabe saluted at the odd request, choosing not to question anymore, he turned to the door, leaving Hibari with his thoughts.

Sharp eyes turned to look at Sasagawa Ryohei still outside the school.

"Another half, like me?" Hibari murmured to himself in interest. Bloodlust shone in those eyes.

Interesting.

Gokudera was lying on his back, watching the sky with bored eyes but then his nostrils flared as he smelled the scent of an approaching human. The half demon groaned as he sat up.

"That bastard Hibari, he realized I was up here?" The Vongola growled. But then he froze when he saw an angel suddenly land in front of him. He scowled at the pure white creature. "What do you want?"

"Gokudera-sama…" The angel bowed lightly, as expected of one of these pure creatures- polite even to the vilest of attitudes. "Red alert has been activated. The prince of ranking is missing and it is our number one priority to get him back."

Gokudera's eyes widened. "The prince of ranking?" An image of the brown-haired kid with his boss flashed in his mind. The silver-haired knew then and there that as right-handman it was his job to settle this for his boss.

Seriousness overcame Gokudera's expression as he asked, "Where's the tenth?"

"He has been reassigned to a different mission by Basil-sama." The angel stated politely.

"Reassigned?" Gokudera repeated the word.

"Yes." The angel said hurriedly and then he added, "And Basil-sama would like me to tell you that Sawada-sam is depending on you."

At those words a switch had been flipped on in Gokudera's head and all of a sudden all he could think of was pleasing his boss.

"I understand! Let's go-!" But before Gokudera could finish, the door to the rooftop opened and Kusakabe came in. He looked at Gokudera, surprised for a second before frowning.

"Oi, do you know the punishment for sneaking int school without permission?" Kusakabe looked around at the roof and seeing no one else with Gokudera, he asked, "Who were yout alking to?"

Gokudera smirked as he placed his hand in his pocket.

"Who is he?" The angel asked warily, staring at Kusakabe's seventies hairstyle.

"No one important." Gokudera said as he tunred his back on the vice president of the disciplinarian committee. "Let's go."

"Go? Where?" Kusakabe asked but then to his surprise, Gokudera vanished from where he was standing. "Wha-?"

What really happened…

Gokudera released his black and white wings letting his demonic and angelic power shield him form human eyes. His school uniform began to change into a black and red toga with dark pants underneath and with black and red chain cuffs on his wrists. His hair was tied up as well and he wore a pair of red sandals.

"Gokudera-sama…" The angel said in exasperation as he watched the shcoked look on Kusakabe's face as he looked around looking for Gokudera.

"What? He'll just be traumatized." Gokudera shrugged and he flexed his powerful wings. "Let's go." He began to fly off and with a last glance to Kusakabe, so did the other angel.

"I'm not going insane. I'm not." Kusakabe said firmly to himself as he began to exit the rooftop.

Gokudera couldn't help but laugh to himself a bit. However his attention was shifted to something else when he saw a familiar bleach haired teen. "Hey that's-" Who is that?

Grey eyes connected with his and Gokudera almost fell from the sky.

I-Is it possible?

C-Could that turf top see him?

"Is there something wrong Gokudera-sama?" The angel behind him ask and Gokudera shook his head.

"It's n-nothing. Just lead the way already." He said roughly and the angel merely nodded. The demonic angel focused his mind on the task at hand, pushing away momentarily the feeling he had about that truf top who met his eyes as though he could see him.

At the same time, amethyst eyes looked at Gokudera before looking back at the strange bleach-haired teen. Hibari placed his hands together at the interesting sight made by the two.

Sasagawa Ryohei, what are you?
