The Rules

[Uni's POV:]

We split up the moment we got off the plane at Clark International Airport. Hopefully, we'd be able to cover more ground and find our psychopathic targets this way. Reborn-ji had insisted on tagging along with me, who had decided to check the schools in Quezon City. Getting into the schools became easier with Reborn-ji around, since he would say he and I were looking for a school I could be enrolled into, at least…

After hours and hours of going around Quezon City, looking for anyone who could possibly have Dying Will Flames or resemble the XIII in any way, we arrived at a certain school. AC, I think it was.

"Maybe we'll find them here?" I said, tone exhibiting just how tired I was. Reborn-ji sighed, "Maybe."

Seriously, we've been going all around this city, and it doesn't seem like anyone we've met so far could be a member of the notorious Vongola XIII. Whoever those seven really are, they're good at hiding their identities.

When we got to the high school building of the school…

"A-ah! I'm so sorry!" I apologized, as I had bumped into someone, causing her to drop the folders she was carrying. The other girl smiled at me, "Okay lang yan." she said, bending to pick up what she had dropped.

"I-I didn't understand what you just said…"

"Foreigner, I suppose?"

I nodded.

"Oh." she laughed a little, "Sorry 'bout that. I said 'it's okay.'" I stared at her features. She had curly blonde hair that was flowing down to her mid-back, her eyes a lovely shade of cerulean blue. By how there was a black ribbon on her head, she resembled the main character of Lewis Carol's story, Alice in Wonderland.

I bent down and helped her collect the papers that had scattered out of the folders. It was only the polite thing to do, right? "I-I'm sorry for bumping into you again…Ah, I'm Uni by the way." I turned to the man behind me, "And that's my Uncle Reborn." Well, I assumed she wouldn't know what I would mean by 'Reborn-ji', so…

The curly-haired blonde gave me a small smile. "It's nice to meet you, Uni. I'm Alice…Alice Cruz." I returned with a smile of my own and continued to pick up the papers.

My eyes fell upon one certain paper. The drawing on it looked like the diagram for some sort of plan, and at the top of the paper was written something I found very odd. 'Greeting Party plan'

I don't know why it struck me as odd…it just did.

"Oh!" Alice took the paper before I could stare at it anymore and hastily put it into one of the folders. She stood up, all the things she had dropped now in her hands again, "Th-thanks for helping, Uni. I f you don't mind, I have to get going now. In a rush, you see." And with that, she sped off.

Reborn-ji and I stared as she disappeared down the hall. "Something was…off about that girl." Reborn-ji stated.

"I know…"

A number of hours later…

The Arcobaleno gathered in the hotel room. "Alright…what have you lot found?" said Reborn-ji, a cup of his favorite espresso in hand. The others shook their heads in dismay, apparently having found nothing.

"What about you, Reborn, Uni? Did you find anything?" Mammon asked, reclining on his chair.

Reborn-ji shook his head. "Nope. Nothing. Whoever those Vongola XIII really are, they're good at hiding, I'll give them that." He sighed, taking another sip of the hot drink.

Silence reigned over the room…that is, until the door was suddenly blown open by maybe a small stick of dynamite. Smoke filled the air, and soon, a figure could be made out amidst the black.

We stared at the person as she slowly appeared at the door. She had shoulder-length green hair, her eyes, which were hiding behind a mask with the Lightning symbol drawn on it, the same emerald color. She was wearing a green shirt under her black jacket, accompanied by black pants and sneakers. "Heya, Rainbow~" she chirped as she raised her right hand, where a ring that was emitting a green flame was.

Fulmine!

Colonnello glared at her. "You sure have guts, midget…recklessly charging into a room full of dangerous people that are after your head…"

"DON'T CALL ME A MIDGET! I'LL KILL YOU IF YOU EVER CALL ME THAT AGAIN!" the greenette screamed all of sudden, stomping a foot on the ground, the flame on her ring intensifying as she did this. She sighed and took a deep breath to calm her nerves, "Now…are you Arcobaleno interested in playing a game?"

Fon narrowed his eyes at her as he slipped into a fighting stance. "We have no interest in whatever games you and your sick, twisted group came up with."

Fulmine grinned at his statement. "Ah, that won't do. Boss doesn't like it when people refuse to play her games…she'll be mad when I tell her you don't want to play."

"I don't give a damn whether your messed-up boss is mad or not." said Reborn-ji as he pointed his gun at the intruder.

She laughed a very creepy and deranged laugh. "But you should give a damn! I mean, if Boss is mad, who knows what she might do!" she stated matter-of-factly, "Did you know that last time someone refused to play Boss' game, Glorietta was blown up?" (A/N: Actually happened. The Glorietta blowing up part, I mean.)

We all stared in either horror or disbelief. They were the ones who blew up a mall entrance, taking the lives of many with it…and that happened only because someone didn't want to play a game?

"You people are sick…" Lal Mirch murmured.

Fulmine giggled and spun around on her heel, running away from the door and down the corridor. "Catch me if you caaaaaaaaaan~~!" Since we weren't just going to let a member of the Vongola XIII escape us again, we chased after her.

We followed Fulmine to an old college called UST. I wonder why she would lead us to a four-hundred-year-old college…

"Hahahaha! You people are so slow!" Fulmine exclaimed as she ran into the campus. However, the moment she ran past the gate and stepped foot onto the school grounds, she disappeared, right into thin air. We all stopped.

"She disappeared…" Lal Mirch said as she panted.

"Probably Nebbia's doing." said Mammon, wiping the sweat off his face as he did. He looked around, "Now why would that little green-haired midget lead us to this place…"

Exactly at that moment, a blood-curdling scream rang. Our eyes widened as we heard the scream, and suddenly my throat felt dry. I prayed that what I thought was happening wasn't really the case. "M-minna…" The other Arcobaleno nodded and sped off.

We managed to follow the heat source to the main building of the school, and our eyes widened at the sight before us. The main building and the buildings near it were burning, the charred corpses of students, teachers and police officers spread all over the grounds. It was…hell.

"Th-this is just…inhuman…" Verde muttered, staring at the burned corpses.

"Soooooo~!" a voice exclaimed madly from above, "How do you like the welcoming party we set up for you, Ar-co-ba-le-no~?"

We looked up and found all seven of our targets…all seven members of the Vongola XIII stood there near the edge of the roof on the main building. Fulmine, Nebbia, Pioggia, Tempesta , Nuvoloso, Sole and Boss…they stood there, oil-filled bottles with paper inside in their hands…they grinned down at us psychopathically.

Boss, whose hands were empty, opened her arms wide, as if to greet us. "Mabuhay, Arcobaleno!" she shouted, her grin widening even more, "Welcome to the Philippines!" Accompanying her welcome greeting was another rain of fire bombs, thrown down by her Guardians.

Now the fire was stronger than it already was…

"You psychopaths…" Fon murmured, glaring at the psychopathic seven.

"Ahh?" Nuvoloso chirped as she grinned wider, somehow able to hear Fon's statement, "Ne, Boss! Can I kill them now? They're annoying!" she connected her ring, which was giving off Cloud Flames, to a purple box. Next thing we knew, she had Cloud-Flame-covered tonfas in her hands.

Boss held her hand before her purple-haired Cloud Guardian, a smirk on her face. "Not just yet, Nuvoloso. I mean, we have a lot of games set up for them! Would be a waste to kill them before they get to play, right~?"

"Oh…Alright then, Boss~"

Reborn-ji raised a brow. "Games?" he glared and held up his gun, pointing it at Boss, "We have no interest in your bloody games!"

"Ah? But you simply must play, Arcobaleno!" Boss gained a dark grin as she said this, "You see…I really hate it when people don't play games when I want them to. If you won't play, then I'll have no choice…but to make the entire world play the game."

We all stared. "…What?" it was Lal Mirch who said it. Boss chuckled lightly, turning to her Sun Guardian. "Sole, please explain the rules of the game to them."

Sole nodded and turned to us. "Listen carefully, kay?" she giggled, "You, the Hunters, have thirteen days to figure out who we are. If you succeed, we'll turn ourselves in. If you fail, however…you'll leave us alone, forever."

Boss gave a smile. "The name of the game is 13 Days. Nice name, ne?"

"Yare yare…Where will you get the expenses for that?" said Mammon. We stared at him in disbelief. Colonnello punched him at the back of the head. "This is no time to be greedy, kora!"

"I just wanted to know…"

Pioggia spoke up, a wide grin playing on her lips. "Where will we get the expenses you ask, Mist Arcobaleno?" she chuckled, "From you, of course!"

Mammon's jaw dropped as he turned to the blue-haired girl, "W-what?! No! NOT MY PRECIOUS FORTUNE!"

"Nuhahahaha!" Nebbia laughed her signature…creepy laugh, "Pioggia's joking, of course. Our expenses for destroying the world will come from White-tan, like they always have."

I raised a brow, "White-tan?"

"Nuhaha…Not telling, cupcake."

"Well, now that you know the rules," said Boss as she raised a number of bombs, "we'll be taking our leave now. Game starts tomorrow." she lit the bombs with her ring as she dropped down all the bombs she had in her hands at the same time, "See you around, Rainbow~"

The bombs exploded at the exact moment that they hit the ground, smoke blocking our view of the Vongola XIII. Once the smoke dissipated, they were gone. I felt worry well up inside of me as I stared at where the psycho seven were prior.

13 Days…

Review, please!
