Ahh, another week, another study session.

It was the weekend again and I was over at Tsuna's house, helping him study for our math class. Our new math teacher has a habit of giving us pop quizzes, so we're playing it safe.

"U-um…i-is it…three?" Tsuna asked hesitantly.

"Wrong." Click. BOOM.

Oh, did I mention that Reborn-san is helping Tsuna study too?

No? Well, I suppose it's to be expected. I'm so scared of him, my mind tries to forget about him.

Anyway, that boom you heard was a small bomb that Reborn-san had set up in Tsuna's room. And the reason why I'm not passing out right now is because Reborn-san was nice enough to give me a pair of ear plugs.

…Did…did I just use, 'nice' to describe Reborn-san?

…That's it, I've officially cracked.

"Wh-what kind of tutor uses explosives to punish their student for getting an answer wrong!" Tsuna shouted, trying to use me as a shield.

"This kind," said Reborn-san simply, "I find that my methods are quite effective."

"And how is this supposed to help me study!" he shouted to Reborn-san.

"The fear of getting it wrong will help you remember the correct answer," he replied.

I sighed, taking out the ear plugs, "Here Tsuna, let me see your work."

Looking over his paper, I heard the clicking of a gun again. Lifting my gaze, it trailed over to the open window, a small boy wearing a cow suit and sporting a large afro was pointing a gun at an unresponsive Reborn-san perched on a tree branch.

…Hold on, a little boy in a cow suit?

It became apparent that Tsuna was just as confused and freaked out as I was.

"Wh-what the-?" he stared.

Reborn-san just opened up one of the workbooks I brought over, "Okay, let's review this section here…"

"U-um, Reborn-san, th-there's someone at the window…" I stuttered.

"Die Reborn!" said the boy. Reborn-san didn't seem to notice him.

"Reborn! There's a kid trying to kill you!" Tsuna was freaking out while I was starting to get clammy from seeing such a small boy wielding a gun.

"I got you now, Reborn!" Then there was a loud creaking sound coming from the tree the boy was on. The branch was beginning to break off and the boy and the branch both fell.

"Eh!" Tsuna and I screamed.

We ran to the window to see if he was alright. We saw him running to the front door and heard Nana-san opening it.

"Hm? Hello?" She was looking around in confusion. Tsuna and I heard small thumps coming from outside his room and in came that boy from outside.

"Long time no see, Reborn!" the boy said, "It's me, Lambo!"

"Reborn-san, do you know him?" I asked. A bit too calmly. Thank you, shock.

But Reborn-san had just ignored the boy, Lambo-san apparently, and was having Tsuna remember some formulas.

"Grr…Don't ignore me, Reborn!" Lambo-san was charging at Reborn-san but was swiftly smacked against the wall by the inattentive tutor.

"Uuuu…I, LAMBO, AGE FIVE, A HITMAN FROM THE BOVINO FAMILY, TRIPPED," he shouted, he's got a good pair of lungs, "I, LAMBO, WHOSE FAVORITE FOODS ARE GRAPES AND HARD CANDIES AND WHO MET REBORN AT A BAR, TRIPPED!"

I felt myself twitching as Lambo-san was screaming his little lungs out, fortunately Tsuna was keeping me grounded by holding my shoulder. We gave each other a look that basically said, 'This kid seems pretty desperate to make himself known…'

"Tsuna," Reborn-san began, "Use this formula to solve this."

"Uh, okay…"

"And Mifune."

"Y-yes?" I asked.

"What do you use here?"

"S-substitution."

"Correct. Now solve it."

I couldn't help but look back at Lambo-san who was again attempting to get Reborn-san's attention by pulling things out of his hair…with little success.

"Mifune, pay attention," ordered Reborn-san.

"A-ah, s-sorry…"

Tsuna and I went back to studying amidst small sniffles from Lambo-san.

"Wahaha! I brought all sorts of special Bovino Family weapons!" said Lambo-san.

More dangerous, mafia, weapons? Oh dear…

"Ta-da!" he took out a large weapon that looked like a miniature cannon, "The Ten-Year Bazooka! Get hit with it, and you'll switch places with your future self for five minutes!"

Tsuna and I both flinched, worried that the bazooka might go off.

"It's just for display, but I'll put it back so it won't go off on accident," Lambo-san said, rather snidely, "Oh!"

I have a bad feeling…

"What could this be?" he asked, holding a small grenade…

A-A grenade!

"NYAHAHAHA!" Lambo-san laughed, loudly, "Die Reborn!"

I saw Reborn-san's arm twitch to block the incoming grenade which then hit Lambo-san which then caused him to fall out the open window…

…We should really close that window…

BOOM!

Ah…it went off…

While I was mentally freaking out about an injured cow-child, Tsuna was talking to Reborn-san, "R-Reborn, who was he, did you know him?"

"Not at all," he replied, flipping through the workbook.

"Huh?" Tsuna and I asked.

"The Bovino Famiglia is a small family in the Mafia world," Reborn-san explained, "I don't associate with those of low status."

"I-is that so…" I trailed off.

"Tsu-kuuun!" Nana-san called. We went downstairs.

"What is it, Mom?" Nana-san motioned toward her leg.

"Isn't this a friend of Reborn-kun's?" We looked down, seeing a beat up Lambo-san covered in scratches and dirt.

"E-eh?" I murmured, tilting my head. As sad as it sounds, I kind of didn't expect him to survive.

"Did they have a fight?" Nana-san asked, "You should help them get along! You too, Chi-chan!"

"W-wait!" we tried to protest, but Nana-san was already walking to the kitchen.

"I'll be in the kitchen!"

Isn't this a nice turn of events? I ask myself sarcastically.

Well, we tried to calm him down, but at the first mention of Reborn-san, Lambo-san began to sob and he ran outside…

"Ah!" we shouted, "Lambo-kun/-san! Wait!"

So we chased after him and ended up at the park. We sat down and waited for Lambo-san to calm down.

Somehow he ended up sitting on my lap and he was telling us how he met Reborn-san.

First off he told that he had wanted to become the boss of his family and the whole world bow down to him (…how is he exactly?) and to do that he had to defeat Reborn-san, a 'top-notch' hitman, as told by his current boss. Then he told us his first encounter with Reborn-san, which was at a bar.

!

Wait a minute!

Lambo-san must be like, five! What's he doing in a bar?

Realizing how wrong this all sounds, my mind decided that it wanted to knock me out now, rather than before when Lambo-san was trying to kill Reborn-san.

…Stupid brain.

Later in the evening when I woke up in my room, I called Tsuna.

"You feeling okay, Chi?"

I sighed, "I've been worse, what did I miss?"

"Um…not much…"

"…You're holding something back." I heard a muffled smack, probably his desk again.

"How do you do that!"

"Later, could you please tell me what happened?"

"Okay, okay," Tsuna relented, "Well, I decided to take Lambo-kun to my house first 'cause I didn't want to risk letting him loose in your house and after I dropped you off I came home and dinner was all ready."

I nodded, an unneeded action, but moving on, "Okay, and I'm guessing that Reborn-san and Lambo-san were in the same room?"

Tsuna grumbled, "Yeah, Lambo-kun tried throwing a knife at Reborn, but it was kmocked back and hit Lambo-kun in the forehead."

I froze.

"…Chi? Are you there? Chi? You okay?"

I shook my head, "N-not really…is Lambo-san okay?"

"Surprisingly, yeah," I heard him ruffle his hair a bit, "But get this, you know that bazooka he took out earlier?"

"Uh huh."

"Well, he shot himself with it, b-but he turned out fine!" Tsuna shouted, worried that I might freeze up again.

"Oh good" I breathed, "What happened next?"

"Well…" he hesitated, "his future self replaced him."

"…huh?"

"Y-yeah, my reaction exactly."

"His future self?"

"Yep."

"O-okay, just keep going, I'm pretty sure my mind will work it all out later."

"Well, his future self was pretty calm at first, he said hello to me and called me Vongola Tenth and told me that it was 'Future Lambo' and he was looking around for you, calling you, 'Chi-nee'."

"'Vongola Tenth'?"

"I know, weird, but then when he saw Reborn, he tried attacking him and everything just…blew up. Literally."

"I would say that you were joking, but knowing Reborn-san, that's pretty plausible…"

He sighed, "Nothing's going to be normal for us anymore, huh?"

I sighed a bit, then smiled, "Well, we still have our sleepovers, if that helps."

"Yeah, that's true," he laughed, "Hey, it's getting late, we should be getting to bed. School's tomorrow."

Insert short pause.

"No way!" we said simultaneously, laughing.
