A/N: Alright, another chapter! Thank you all for following and liking this story, I'll try to update once a week. Feel free to leave a review, they always brighten up my day. :)

Encounter with a UMA

Gokudera's first impression was that the wannabe Decimo looked like a strong gust of wind could knock him over. He glared at Tsuna as the brunet gave him a confused look. He kicked over Tsuna's desk and sneered, immediately feeling killer intent. He looked around the room but couldn't identify the source. Behind the exchange student Shizuka was glaring at the teen. Tsuna just sighed, the new kid just had to piss his sister off.

"He's only been in homeroom for ten minutes and that delinquent decided to pick on you. How dare he!" Shizuka scowled, her hair starting to resemble flames in her anger. "Please don't send him to the hospital this time." Tsuna begged, Shizuka looked thoughtful. "Psychological?" She ventured. "All he did was kick a desk, that doesn't warrant being sent to a psych ward!" Tsuna protests. Honestly, the students of Namimori were lucky that Tsuna could somewhat rein his sister in.

That day, anything that could go wrong for Gokudera did. It started out small, with the ink in his pen somehow overheating. This wouldn't have been too big of a deal, if he didn't have the habit of chewing on the end of it. He had been thinking about how to approach Tsuna and brought the pen to his mouth, instantly regretting it when he tasted the ink seeping from it. His classmates watched as Gokudera sputtered, trying to get the taste out of his mouth. Shizuka looked at the teen with a grin. "Well that worked better than expected. I lucked out on that one."

In an attempt to get the metallic taste of the ink out of his mouth, Gokudera decided to go out for a smoke. Shizuka looked at the teen and shook her head. "Moron. Anyone at this school knows not to break the rules. Hibari will be thrilled to set him straight." Shizuka says with a menacing grin, making Gokudera shiver and fail at locating the source of the killing intent once again.

It was a straightforward process, all Shizuka had to do was temporarily take over one of the students and inform Hibari of Gokudera breaking school rules. Shizuka exited the boy's body, leaving the teen confused and terrified when he heard Gokudera's cursing and pained screams. Hibari was already irritated by a prank Shizuka had pulled on him earlier, moving objects in his office just enough for him to notice, and took his anger out on the Italian. Shizuka cackled with glee.

The final prank was revealed when Gokudera went to his shoe locker. His outdoor shoes were completely melted, now resembling a tar-like substance. Gokudera growled, those were Italian leather! When he found the punk that was messing with him, he was going to blow them sky high!

Tsuna could only sigh in exasperation as his sister gleefully acted as a spirit of vengeance on his behalf. "Shizuka, aren't you going overboard?" Tsuna asks, Shizuka puffed out her cheeks. "Come on Tsuna, connect the dots. Didn't your teacher say that the transfer student was from Italy? And isn't it a little suspicious that he arrived here only a couple of days after Reborn invaded our lives?" Shizuka asks. "He looks like a delinquent but I don't think he's a criminal!" Tsuna protests, Shizuka shook her head. "I swear, one of these days your own kindness is going to bite you in the ass."

By the time that Gokudera had challenged Tsuna in the school yard, he looked like he had been mauled and was trying to hide his fidgeting. Shizuka watched from beside Tsuna, admiring her handy work. "I'll give the kid credit, any normal teen would have run for a priest by now. Or killed someone." Tsuna kept quiet, though he really wanted to refute what she was saying.

Gokudera pointed a finger dramatically at Tsuna. "You're not fit to be Decimo. I'll just kill you and take the title for myself!" "Called it! I totally called it!" Shizuka exclaims, hers and Tsuna's faces paled when they saw the teen take out dynamite. The pranks that Shizuka did only made the already short-tempered teen's fuse even shorter. Tsuna took one look at his sister and deadpanned. "If I die, I'm not speaking to you in the afterlife." He says bluntly, being forced to dodge the explosives thrown at him.

The explosives shook the school grounds and had Shizuka wondering why Hibari wasn't on the scene yet. Both she and Tsuna were oblivious to the fact that Ryohei's loud shout of "Extreme!" had made him the newest target of Hibari. He was one of the few students that could withstand more than one hit from the bloodthirsty teen and would see the fight as "training." After watching Tsuna panic for a couple minutes Reborn finally decided to shoot him with a deathperation bullet. Shizuka yelped when she saw herself becoming visible again, throwing the Italian off guard.

"Where the hell did you come from?!" Gokudera demands. "I'm a ghost haunting my older brother." She says bluntly, not even bothering to use a more realistic excuse. Gokudera had dropped some of his dynamite in shock and Tsuna snuffed out the fuses. The rest, they say, was history.

"Oh my kami, I've never wished for someone to ignore my existence before. He keeps asking me so many questions!" Shizuka complains, sulking in Tsuna's room. After declaring his loyalty to Tsuna, he immediately started grilling Shizuka on what being a ghost was like. She humored the Italian at first, answering some questions that the teen had. No, she couldn't possess everyone. Yes she could move objects, but it took energy to do so. Yes she had flames, just like everyone else. The limit of her patience was reached when he was starting his fifth page of notes.

"What does he mean he wants me to possess his body? Is he insane?!" Shizuka yells, looking ready to pull her hair out. "Gokudera, it's not a good idea. Just trust me on this one." Tsuna comments, remembering his trip to the nurse's office. Gokudera was undeterred. "But I want to know what happens when someone is possessed! Isn't there anything that you've wanted to do in someone's body that you haven't done?" Tsuna could see the wheels turning in his sister's head. "I'm saying this as your friend and because I care about your life. Don't give Shizuka free rein of your body, you'll regret it."

The cashier at the bakery didn't know whether to laugh or drool when an animated delinquent teen walked into the store. He looked at all the desserts with childlike glee. Reborn and Tsuna just watched as Shizuka ordered way too many cakes for Gokudera's body to handle. "All that she wanted was cake?" Reborn asks, Tsuna sighed. "She saw some other girls going to this store for a self-appreciation day and wanted one too. I don't think we'll be seeing him tomorrow, Shizuka tends to forget about the limitations of the human body."
