Target 06 Discovery

"Where do you think Hibari has stashed those guys from earlier?" Tsuna asked.

They were sitting in her room, eating the sushi Mr. Yamamoto has given them before ushering them out of his restaurant, his face blank and emotionless. Takeshi had been offered to come with but the teenager had refused, stating he much preferred staying with his father. It was a remarkable show of loyalty especially considering that there was a possibility the two men had companions who would come looking for them if they were gone too long. Tsuna didn't think she could have stayed there with the risk of other gun-wielding foreigners come crashing in. One encounter with gun-wielding maniacs was enough for her, thank you very much.

"I don't usually think of those things," Hana admitted, biting her lips. She had recovered remarkably from her first experience of being held at gun-point and was mostly back to her old self. Tsuna wasn't surprised. Hana had shown admirable adaptability in the past.

"I don't care," Kyoko added her two cents, her arms wrapped around her body, her face pale and withdrawn. Shock had made her uncharacteristically combative. The usual Kyoko never would have said that she didn't care, no matter how rotten the person was. "As long as they never come back."

At least that, Tsuna agreed whole heartedly. Although, she was still curious as to where Hibari brought his victims. She imagined an abandoned warehouse full with bloody bodies, some alive and some dead, and shivered. OK, maybe she wasn't that curious.

"You know what bothered me the most?" Hana suddenly piped up, gaze intense, "It's how fixated they were on you."

Tsuna glanced at her. Yes, that had been something she had thought about.

"That was a little weird," she admitted, trying to forget the way foreigner number 1 had looked at her before something about his boss rewarding him handsomely. And why had Mr. Yamamoto look so defensive of her? There was something inside her that was telling her it was more then about protecting a child from danger. "Maybe I just look like someone they know or they are trying to find?"

"Who?" Kyoko asked and Tsuna laughed mirthlessly.

"Well," she snorted, "Isn't that the million dollar question?"

School the next day was almost like an anticlimactic ending to an otherwise engaging and breathtaking action movie. Nothing changed, for the better and for the worse.

"Dame Tsuna! You are supposed to catch the ball, not let it hit you in the face."

"Idiot! You made our team lose. Clean the whole gym up by yourself!"

Except…

"Tsuna!"

"Yamamoto!" Tsuna said, surprised. The teen looked terrible, his hair a mess, his uniform disheveled. Why was Yamamoto here? Didn't he have baseball practice after school? Tsuna really couldn't see the boy skipping practice if it was not for a good reason. Yamamoto loved baseball more then anything else in the world. Tsuna thought that the only reason he came to school at all was because of baseball. With all that said, Yamamoto's appearance was enough to put Tsuna on edge. "What's wrong?"

"Dad left a few minutes after you guys," Yamamoto replied, wringing his hands as a show of nerves. Tsuna's eyes widened a little although for some reason, she wasn't all that surprised. "I waited for him all night and he never came back. I'm seriously worried especially with what had happened yesterday."

"You should be," Tsuna admitted, remembering the two men with depressingly accurate details. They had been terrifying. What had been worst was that something in their eyes had told Tsuna that they wouldn't have hesitated to shoot them if Hibari hadn't shown up there and then. Yamamoto was right to be freaked out. The chances of something bad happening to his father were pretty high considering the circumstances in which he vanished in. Although she didn't know Tsuyoshi Yamamoto really well, she knew how painful it was to lose a parent. "Maybe we should ask Hibari? Your father probably went to see him."

Yamamoto brightened a little at that. He had obviously not considered that possibility before hand.

"Good plan," he said, "I knew I could count on you Tsuna."

Tsuna blushed a little at the praise, still unused to being called "good".

"Don't worry about coming with me," Yamamoto continued, "You still have to finish cleaning and I don't want you to get in to trouble for my sake."

"Are you sure?" Tsuna asked, more then a little relieved. Her increased interactions with Hibari on a more personal level hadn't cured her of her fear regarding the prefect.

"I'll come back to join you later on."

With that, Yamamoto turned on his heels and rushed out of the gym. Tsuna stared after him, feeling queasy and uncertain.

Hibari had no idea where Mr. Yamamoto was and the ignorance obviously rankled him because he actually offered to have some of his minions look in to it. Hana, upon hearing the situation, suggested that they go back to the scene of the disappearance.

"Victims always leave behind clues," she said and Tsuna glared at her for her choice of words.

"Tsuna," Yamamoto said, turning to the girl, "I really hate to bother you but can you help me one last time? Two heads are better then one after all and I need all the brainpower available to figure this thing out."

Luckily, by the time that was said, Hana was long gone or else Tsuna was certain she would be laughing her head off at the mere prospect of the two of them generating enough brain power to solve a mystery that left even Hibari in the dark.

"I have no problems with that," Tsuna said, thinking of her empty house and her mother's comment about going to diner with some friends that evening.

"Thanks Tsuna," Yamamoto said and offered a small smile. He was looking better already and Tsuna was proud to have been the source of that amelioration.

The Yamomoto abode was situated a floor above TakeSushi which must be very convenient opening up shop in the morning.

With a key he had extracted from his bag, Yamamoto unlocked the front door before ushering Tsuna inside.

"It's this way," Yamamoto said, turning left from the entrance and going up a set of stairs the girl had not previously noticed. The stairs were narrow, just painted steps without any carpet and the treads themselves were poorly late and difficult to walk on. Tsuna knew that if Yamamoto hadn't taken out his cellphone to provide better illumination, she would have missed a step and killed herself in the subsequent tumble down. Fortunately, that did not happen and they managed to arrive at their destination without any major mishap.

"My father's study is this way," Yamamoto said, grabbing on to Tsuna's arm to drag her down a long corridor. He pushed open the first door to their left and here they were, in a miniature library that probably contained over 100 books.

"Wow," Tsuna said, taking in the book cases towering over them. "I never knew your father was such a scholar. Have you read any of these books?"

"He is," Yamamoto smiled a little at that, "And no, I haven't. This is the first time I've been in this room without dad. He hates when I touch his stuff without permission and I had never gotten permission to see what these tomes were all about. If there is any clue regarding his disappearance, I'm sure we'll find it here."

Tsuna took another step forward.

"This is incredible," she said, gingerly taking one of the thinnest volumes out of its hiding place, "Oh dear, this one is entirely handwritten."

She flipped through it.

"This is a contract of some kind," she said deducing that fact from the signatures at the very end, "Although I can't understand anything because it is written in another language."

"It's Italian," Yamamoto replied unexpectedly, "Dad knows people from there."

Tsuna slid the volume back where she had taken it from and continued her search.

Most of the volumes on the first bookcase turned out to be in Italian, something that infuriated Tsuna a great deal. Yamamoto laughed a little at her disgruntled expression and reassured her that they are making decent progress and that she shouldn't let this bring her down.

"You can look at the pictures," he joked. Tsuna stared at him, wondering how looking at the pictures would help them find out with Tsuyoshi had gone to.

An hour passed in the same manner and by 6 pm, Tsuna was so sick of looking through dusty manuscripts that she seriously debated whether she should invent an excuse and get herself out of there. Yamamoto could probably continue on his own, she thought. After all, the boy had demonstrated a basic grasp of the Italian language - probably due to his father's tutelage - unlike her. At least he seemed to understand the nature of most of what he was reading.

Tsuna sighed, pushing up from the crouching position she had been in for the past 10 minutes and stretched.

"Ah, that feels good," she said in satisfaction, momentarily closing her eyes. She opened them though when Yamamoto cried out: "Tsuna, watch out!"

Shit, Tsuna thought as something buzzed past her, causing her to stumble backwards and hit the bookcase behind her with a solid thump. The book case trembled a little under the assault and just as Tsuna was breathing a sign of relief that nothing had fallen, she felt something hit her head.

"Oww!" she cursed, rubbing at the victimized area, "What on Earth!?"

"Sorry," Takeshi said sheepishly, rushing to her side. He did look a little guilty for yelling out like that so Tsuna agreed to be more generous. "It's just an insect. When I heard the noise, I thought it was something else."

He didn't have to say what he had thought it was.

"That's OK," Tsuna sighed, deciding that this was probably fate's way of telling her it was time to leave. She sighed, bending down to retrieve the fallen book and nearly dropped it again when first contact with the volume sent a pulse of warmth down her fingertips to be propagated all over her body. She suddenly felt calm, serene, almost as if all her worries were gone. The constant buzzing in her head that had been her companion for about 10 years now has finally subsided as well and Tsuna, for the first time in her life, was able to think clearly.

"What's wrong?" Yamamoto asked when he had noticed her reaction. He glanced down.

"La Storia della Vongola Famiglia," he read, "The history of the Vongola Family. That crest looks strangely familiar. Where had I seen it before? Tsuna, do you- Oh dear God Tsuna! You head is on fire!"

TBC.
