Keep on reading…and please review at either the end, or at each chapter end…

Ah, yes, and so appears another familiar face. :]

"Lambo…? I-Pin…?" Kaia called out softly. She looked around and decided to reluctantly drop by Tsuna's house. Of course, Lambo lived under the same roof, so someone there would obviously know what became of Lambo. The Sawada nameplate came into view, and Kaia carefully entered the front yard. She came up to the door and knocked.

The door opened, presenting a vaguely familiar face.

"Hello~! Aren't you Kaia-chan?" beamed Nana.

"Umm, I'm looking for Lambo-chan and I-Pin-chan…" Kaia began. "Do you know where they went?"

"Ahhh, well the last time I saw them was when Bianchi took them out for shopping with Fuuta-chan…" Nana answered. Kaia nodded.

"Arigato-goseimasta~!" Kaia bowed, and she ran past the front gate of the Sawada household, in the direction of the shopping district. Nana just smiled on, beaming with pride. Her expression softened to a smirk. Nana laughed to herself and shut the front door, so she could resume her activities.

Meanwhile, Kaia ran to the shopping district, again, along the narrow little road Gokudera walks on. Randomly choosing an exit, she turned off the main trail and out into a crowd of shoppers, taking advantage of the weekend sales. She looked left and right, but found no toddlers running loose.

But she wasn't completely blind to everything else, either. There were people who kept looking at her. Kaia thought it was suspicious, but put that at the back of her mind. Her focus was to get Lambo and I-Pin to safety.

She decided to check the park next; the quietness of the place would prove simple to hear Lambo's loud, obnoxious comments. However, the place was packed with people going on walks; chatter was everywhere. Kaia kept away from there, and slipped into the grid of neighborhoods. It was quiet there, and it satisfied Kaia. She would immediately know whether Lambo is within the unmistakable range of fifteen meters.

Suddenly, an explosive went off at her feet. Kaia jumped backward with fright and looked up; a fully suited teenage boy, around seventeen, stepped out, grinning like a maniac.

"So I get to kill the little Vongola for free? I like playing around with toys~!"

He had white hair, triangles under his left eye. He was smiling a perfectly harmless smile, but in his hand was another explosive. He had a ring on his right hand; Kaia wondered what that was for. But then she recalled Tsuna, Gokudera, Yamamoto, Lambo, even Hibari, they all had rings.

"Wh-Who are you?" blinked the apparently unfazed but confused Kaia.

"You may call me Byakuran. Nice to meet you, Kaia-chan."

O0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o

"EHH?! You asked the Gesso Family to fight her?!" paled Tsuna. Reborn nodded.

"Not only that, there are land mines that are buried throughout the city that could be only set off by herself. Also, there are hidden machine guns like the ones you have seen in the Cloud Battle. The young, upcoming Boss was happy to fight Kaia himself."

"Upcoming Boss?" repeated Tsuna.

"Like you, Tsuna. A Boss-to-be," explained Reborn.

"But, Kaia can't fight!" the flustered Tsuna emphasized. "She doesn't know anything about the mafia either!"

"You should know, Dame-Tsuna, that this wasn't only for Kaia to become your right-hand," frowned Reborn. "Your father had to call in the Gesso himself, of course, with permission from the Boss. The Gesso have never been friends with the Vongola, however they seem to be eager enough to fulfill our wishes. This is a lot bigger than you would imagine." Gokudera immediately paled.

To think that they had called in an enemy for Kaia's sake, this was a lot more important that he could have ever thought possible. But, again, how exactly was Kaia going to be involved? It seems already that Kaia would be a major factor in the success of the Vongola, in the successful transfer of the seat of Boss.

"Don't worry, though. The Gesso Family aren't that powerful, and they're not a very large family either," Reborn added.

"But…" Tsuna shook his head.

"Juudaime, cheer up! Reborn wouldn't do this on purpose if he knew that Kaia would die for sure!!" grinned Gokudera. "I want to get yam! You want to come with me, Juudaime?"

"Ehh- y-yam?" Tsuna blinked in confusion.

"Yeah!!" beamed Gokudera, trying to cheer up Juudaime. Dwelling too long on Kaia would be boring, too. It was Saturday; talking all day wouldn't be fun.

O0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o

You guys are probably asking why Tsuna's dad had to invite the Gesso to Japan. The reason is to see if Kaia can utilize the skills she learned against a living opponent. That was it. She had to be useful if she's going to be part of Tsuna's family.

Anyway, keep on reading…there's three more scenes to go!
