"We're going to Ikebukuro."

Silence pierced through the very small and messy bedroom. All nine occupants froze, stunned in to quiet. Yellow birds chirped and whistled outside the dusty window. Bicycles cruised by. People went on with their daily lives, oblivious to the stupefaction the middle school kids in that one room were feeling. Thereupon, chaos broke out. It was truly the quiet before the storm.

"Hiiiiiiiiiieee!" The one and only 'Dame-Tsuna' shrieked, backpedalling in to his bed frame.

The sudden jerking of the bed caused the great 'Lambo-sama' to fall off, face-first in to the cold floor.

Bull horns trembled as the little kid sobbed, "G-Gotta… keep… keep… it… keep it in…"

"Infant, I did not agree to such a trip," Namimori Middle Discipline Committee Leader, Hibari Kyoya shifted in to a guarded stance, his hands on his metal tonfas.

'Smoking Bomb' Gokudera Hayato gritted his teeth, his eyebrow twitching as he yelled, "Stupid cow, shut up! You're disturbing the Tenth!"

"Group trip to the extreme!" Sasagawa Ryohei pumped a bandaged fist in to the air, barely missing the ceiling.

Basil simply smiled pleasantly, and remained at his spot in the corner of Tsuna's room. Chrome Dokuro chewed on her full bottom lip, her violet eyes flickering worriedly.

The Sun Arcobaleno Reborn twitched, immediately transformed his trusty chameleon in to a huge green hammer, bringing it straight down on Tsuna's tear-streaked face.

Yamamoto Takeshi chuckled, albeit a bit weakly. No one noticed the flash of nostalgia that glimmered in his chocolate-brown eyes.

"Shut up and listen to what I have to say, Dame-Tsuna!" Reborn ordered sternly.

After fifteen minutes of arguing and difficulties, the bedroom looked like a tornado had been through it. The chair was beyond crooked and bed sheets were crumpled on the floor. Quiet reigned over the normal-looking, or maybe not so, house. Let's just say that this peace wouldn't last for long.

Reborn settled back in to his seat on Tsuna's wooden desk, with his arms firmly crossed and irritation darkening his face.

"As I was going to say, we—meaning Dame-Tsuna, all his Guardians and me—are going to Ikebukuro for the extent of the summer holidays on the orders of the Ninth. Basil will be our guide and also Vongola Headquarter's way of passing on any change in orders," Reborn told them, speaking slowly as if he thought they were possibly mentally retarded.

Well, he probably did.

Tsuna was the first to protest, "B-But-! Ikebukuro is a bit-! I have summer homework! I'm definitely not going!"

"You have no choice, idiot," Reborn informed him, accentuating each word with a kick to Tsuna's face.

Hibari narrowed his eyes dangerously, "I will not leave Namimori."

"You will have the chance to fight many strong people, all of which might pose future threats to Namimori, Hibari," Reborn bribed—ahem, proposed with a grin.

Hibari measured this thought silently for a moment before smirking, showing his approval. His tonfas disappeared from sight as the raven-haired male leaned back against a wall, as far away as possible from the crowd.

At this, Tsuna gaped. The biggest obstacle to this 'trip' was now gone. His chance of escaping this was near to zero now.

Gokudera replied earnestly, "I will go to protect the Tenth! Worry not, I shall not fail in my mission!"

"Ahaha, if you want Lambo-sama's help, you will have to beg, you know!~" The five-year-old child picked his nose with arrogance. "I guess I can't help it. Lambo-sama will go to save crybaby Tsuna. Be happy!"

Ryohei simply repeated, "Group trip to the extreme!"

He coupled this with a few strong punches to the air that almost hit Gokudera. This caused a small (read: huge) riot involving shouts of 'turf-top' and 'octopus-head'.

Chrome tilted her head, blinking innocently, "Boss. I will go. Mukuro-sama says that this 'trip' might turn out to be interesting so…"

What happened next was completely unexpected. Yamamoto did not reply with a 'maa, maa' and smile brightly.

Instead, with a nervous expression, he addressed Reborn, "Ah, sorry, but can I get a 'pass' from this?"

Everybody was suddenly stunned in to silence. Yamamoto fidgeted a bit, running a hand through his short black hair.

"What's wrong, Yamamoto?" Reborn questioned with a slight frown.

A strained smile, one you never expected to see on Yamamoto's face, answered them, "It's just that… that place holds… How do you say this?"

"Ikebukuro…" Yamamoto pushed out the five syllables with trouble, "It holds bad memories for me."

Reborn assessed the tall baseball player carefully. He had heard that Yamamoto had been staying in Ikebukuro for a period of time before. Could this hesitancy have something to do with that?

Gokudera broke the tension with a snarl, "Oi, baseball-idiot, don't give me crap. If you don't go, you'll be spoiling this for the Tenth."

"Gokudera-kun-!" Tsuna hurried to interrupt, wary of Yamamoto's feelings.

The pain on Yamamoto's face was plastered over quickly with a fake smile, "You're right, Gokudera. We don't want Tsuna to be upset, huh? I'll go."

"Yamamoto-dono…" Basil murmured, stepping forward.

Hibari watched with suspicious eyes and Chrome simply stared emotionlessly. Even Ryohei didn't speak in this moment of gloom.

Reborn reluctantly turned away from this new, strange Yamamoto to explain the purpose of this 'trip'.

"All of you should know that the Vongola have control over many famiglias, right? Like the Cavallone famiglia. Well, not all of these famiglias reside in Italy. There are three famiglias, or as they are better known as, colour gangs, in Ikebukuro. The Blue Sqaures have been recently more or less wiped in a war with the Yellow Scarves. However, there is now an upcoming war between the Yellow Scarves and the Dollars—"

Ryohei interrupted with a disbelieving tone, "Blue Squares? Yellow Scarves? Dollars? Those are weird names to the extreme!"

"Turf-top! Don't cut off Reborn-san!" Gokudera scolded roughly.

Ryohei jumped forth, "What's your problem, octopus-head?"

Lambo muttered in his sleep. Actually, when exactly did he fall asleep in the first place?

"Sasagawa-dono, the Blue Squares and Yellow Scarves are named such because of they are colour gangs," Basil raised a finger in explanation. "As for the Dollars, it is said that although they are a colour gang, no one knows what colour they are. Therefore, most people say that they are colourless. I heard that they basically do nothing, going 'dara dara' all the time, and so were named 'daras', or 'Dollars'."

Ryohei's face screwed up in concentration, "Eh? I extremely do not get it!"

Tsuna's eyes also sported the same swirls.

Before chaos could ensue, Reborn fired a warning shot off his gun, "You guys, be quiet so I can continue."

"As I was saying, the Yellow Scarves and the Dollars will be going to war over certain 'Slasher' incidents. The 'Slasher' seems to be another driving force in Ikebukuro. The details are uncertain but by order of the Ninth," Reborn held up the parchment that sported a small flame at the top, "We need to stop this war."

"Hiiiieee!" Tsuna curled up at the mention of 'stopping a war'.

The noise level increased at an amazing rate after that, while fights started in the Sawada household. Hibari stormed out of the house, destruction in his wake. Chrome left quietly, comparable to a ghost. Basil took over Yamamoto's place as a peacemaker. Talking about Yamamoto, he seemed to be lost in his thoughts the entire time.

"Anri!"

The young girl in question jumped at the sound of her name. Her choppily-cut locks brushed against her high cheekbones when she turned, smiling shyly at the young boy. Yamamoto grinned easily, walking up to her.

They chattered at a little corner on the elementary school's rooftop. Other cliques munched on their lunch at their own corners.

"As I thought, it's you, Anri. Where's Mika?" Yamamoto asked.

Anri fingered her round glasses softly, "She's meeting up with some classmates so I left since I would only be in the way."

"Oh, were those 'classmates' Rikka and her group?" Yamamoto guessed.

At Anri's affirmative nod, he added, "They're quite popular, aren't they?"

The two basked in each other's tranquility and the sweet smell of sakura that the breeze carried. Anri typed nimbly and quickly in to her plain silver cell phone, while Yamamoto slurped at his strawberry milk. Abruptly, a multicoloured burst of light exploded in the cloudless sky. The duo twitched at the sudden sound, spinning wildly to face the sight.

"P-Pretty..." Anri whispered in awe.

Their schoolmates hurried to push themselves against the fence that separated the rooftop from pure nothingness. Light whispering broke out among the amazed students.

Yamamoto blinked in surprise, "Those are... fireworks, right?"

"I heard that Raira Academy's having their cultural festival today," Anri informed him with a sweet smile.

Instantaneously, a light bulb flashed above Yamamoto's little head, warning others of possibly reckless ideas. He latched on to Anri's wrist and together they propelled themselves across the rooftop and down the stairs.

"Wha—Yamamoto-kun? Please wait!" Anri stuttered, stumbling after her male counterpart.

Yamamoto grinned, "There's still time before lunch ends! Let's go to Raira and see the fireworks firsthand!"

The two elementary school kids dashed out the school gates and down the street, ignoring the shouts of some adults who noticed them. Cars zoomed by and people continued with their own routines but the two children just raced towards Raira, following the beautiful lights. Their small forms were quickly lost in the crowd at Raira's parade square.

They were just two kids watching the fireworks. Two kids being reckless. Two kids have fun. Two kids that were happy.

Yamamoto tore himself out of the flashback. He was different now, more mature. He couldn't go back to those old times anymore. He wouldn't put Anri through danger anymore.
