Prologue

Tsuna sat down in front of the rectangular package that lay on his table. The reddish brown paper wrapping and the golden ribbon made it look suspicious. He thought it was a gift from his mother when first gave it to him, but she told him that it was delivered by the mail man and addressed to Tsuna. Then, he thought it was Reborn's doing, but the arcobaleno told him he didn't know what it was either.

"Dame-Tsuna, why don't you just open it and see what's inside? Staring at it won't change anything." The Mafioso said, interrupting the silence that had engulfed the room for the past thirty minutes.

"But it looks so suspicious!" Tsuna replied, holding it up. "What if it's a bomb or something?"

"Don't you think it would've blown up by now if it were a bomb?" Reborn rolled his eyes, crossing his arms. "Stop being such a wimp and open it already."

Tsuna sighed and set the book back down. It really could have been a bomb! Well, at least he thought it could be. Maybe Reborn was right? It's probably harmless.

The brunette carefully untied the golden ribbon, then turned the package over. There was a red wax stamp with a strange emblem pressed into it, reminiscent to that of a crest or something. Tsuna impatiently tore the paper wrapping off, revealing a burgundy colored book. It looked something like a fancy encyclopedia, and there were gold trimmings lining the cover and spine of the book. The title was also in gold, and said 'Kingdom'. The book looked so elegant, Tsuna felt as though he should be careful with it; he thought it could break if it wasn't handled with care.

"A book? But why?" He thought aloud, examining the cover and back. "What is 'Kingdom' anyways? Is it a foreign book?" He continued, turning to look at Reborn.

"Who knows." The arcobaleno shrugged in response. "Why don't you open it and see what's inside?"

Tsuna paused. He felt as though something bad would happen if he opened the book. What if monsters popped out or something. He blinked. Of course that wouldn't happen, right?

"Dame-Tsuna, what are you waiting for?" Reborn jumped down from where he was sitting and kicked the brunette's head.

"Ow! That hurt! Okay, okay, I'll take a look, geez!" Tsuna groaned, opening the book.

Suddenly, a bright white light engulfed the room, nearly blinding Tsuna and Reborn.

"W-what's happening?!"

"Ngh... Huh?" Tsuna blinked. He was lying down on something soft. He sat up and rubbed his eyes, a looked around. "Eh? Where... Where are we?"

He was sitting in the middle of a garden. There were tall rose bushes surrounding them. Tsuna thought they could be walls. The grass underneath him was a healthy green, and some flowers were sticking out of the ground.

"Eh? Tsuna, is that you?" A familiar voice called.

The brunette turned around, and his eyes widened. "Eh?! Why are you here too?!"

Hi! It's your problematic fav, Kusuri! Wow, I refer to myself as "your problematic fav" a lot now recently, haha!

Anyways, this story is a crossover between my original story and otome game I'm working on making! I hope you'll enjoy it! I won't be revealing the name of the story/game though, until later!

Just in case you're wondering, this story will in fact have many OCs, but there is no romance involved between my characters and the Vongola, obviously because my original story is already romance based.

I just thought it'd be interesting to do a crossover between my story and KHR, because they both have to do with mafia! Haha!

Alright! Until the first chapter then! Ciao~!
