Ugh, this is why I shouldn't take a break from writing. It's taken everything I've got to get this out, and I'm still not happy with it (and on that not, GC will be at least a few more weeks while I try to wrangle it into shape). Hope it's satisfying regardless.

Chapter 13

"School hours are over. Leave the premises or I'll bite you to death."

Hibari didn't wait for a response before his tonfas were already in hand. The literature club – who had been foolish enough to think the prefect wouldn't notice them lollygagging at the end of club activities – didn't need another warning, all but falling over themselves to make it to the door. Hibari kept eyes on them until they'd all bolted for the door, before turning back towards the Reception Room.

"Kusakabe" he said, the larger teen quickly falling into motion behind him. "Has the patrol been complete."

"Yes Hibari" he confirms. "Tochiro just confirmed the third floor has been cleared. School is closed for the day."

"Hn, good. You're excused."

The older teen gives a quick bow before heading for the exit himself. It's not a good thing for even the Disciplinary Committee to loiter when given orders to leave. Hibari catches a glimpse of his prefects all heading out the gate themselves, but he still has paperwork – preparations for the future that must be seen to before he can join them. These are best done in solitude.

However, when he enters the Reception Room, he's not alone. There's a toddler-sized hitman drinking tea on one of his couches.

His face is also completely covered in bugs.

Hibari's eyes narrow.

"Baby. Pets are not permitted on school grounds."

The hitman greens, and tips his hat.

"They're not pets, they're my minions, Tsuna."

Hibari's eyes narrow, and he strides towards his desk, the first paper in his hand before he has even sat down.

"I haven't seen the small animal since this morning" Hibari replies. "All students, members of staff and civilians are to be off the premises by this time. Leave or I will bite you to death."

Reborn sets his teacup down, but otherwise doesn't move.

"That was an impressive display with the football team" he says. "It might not be your body and have muscle memory on your side, but you still clearly know what you're doing."

Hibari glares at him. Reborn doesn't stand down.

Finally, Tsuna-Hibari sighs, slumping back in his seat and rubbing his eyes. "How did you know? I thought I had Hibari down perfectly."

"Oh you do" Reborn admits. "I actually couldn't tell."

Tsuna-Hibari frowns. "Then how did you- "

"Because my contacts spotted Yamamoto crushing skulls in town" Reborn replies, gesturing to the insects on his face (and is rather pleased that Tsuna doesn't bother hiding the shudder this time). "Which means Hibari isn't here. He only allows you and Hana to possess him, and since Hana is currently in a tutoring session for both you and Ryohei, logic dictates you gave your body to Yamamoto and took Hibari's. Doesn't matter how good you can imitate someone if they can't do the same."

Tsuna-Hibari laughs. "Yeah, Hibari doesn't even try. He's unabashedly 'Hibari', no matter what he looks like. Do I even want to know why you were looking for me?"

It's a valid question. Over the last month Reborn has gotten…tolerant is probably the wrong word, but nothing else adequate springs to mind, of the switching, with the understanding that he'll get his hands on Tsuna to train at the end of the school day. For him to chase Tsuna up mid-switch has become a rare event. One that usually means trouble.

"I came to give you fair warning" Reborn admits, hopping over to the desk. Tsuna-Hibari winces, clutching at papers and filling out the paperwork in a desperate attempt to avoid what's coming. He completes everything but the final signature (even Hibari draws the line at Tsuna trying to imitate that), before squaring his shoulders and facing his tutor head on.

"What do I need fair warning for this time?" he moans.

The baby grins.

"There's a new hitman in town. An old friend of mine."

"A 'Gokudera' kind of friend, or another kind of friend?" Tsuna-Hibari asks.

The tutor cracks a smirk, and Tsuna's stomach drops.

"Funny you should phrase it like that…"

A few minutes later at a small convenience store not far from the school, Gokudera is roughly handing over a bag of groceries to a rather flustered customer when his phone starts ringing. The number fills him with glee, and he all but skips outside to answer while his manager flails in the background at his unprofessionalism.

"Tenth! Have you finished helping that demon-"

"Gokudera, Reborn says your sister's in town. How bad is this?"

The bomber chokes.

"I'm sorry, do you want to repeat that?" Hana asks, arms folded and face a perfect picture of disbelief.

Tsuna sighs. Once he'd gotten the basics out of Gokudera, he'd asked the study group to meet him outside school when Hibari returned. The prefect must have had a very good patrol, because not only was Yamamoto's body returned in almost perfect condition, he let them crowd outside the gate with only one warning. This meant he could warn everyone of the coming storm.

"I said, Gokudera has a sister, Bianchi, and she's coming to Namimori of her own volition" Tsuna repeats. "She's also a hitman, so is probably here to kill me."

And wow, it was probably telling at how used to crazy he was at this point that such news barely phased him. The 'not-even-god-can-touch-me' high of being Hibari probably hadn't worn off yet.

"She could just be here to visit her brother!" Kyoko insists, but Tsuna shakes his head.

"Gokudera says they haven't spoken in years" he replies. "He was vague, but I got the feeling he really, really doesn't want to see her."

Which was an understatement. The bomber had been horrified at Tsuna's questions, and had started listing off a list of weapons and defensive armaments he needed to accumulate in the next twelve hours, hanging up with an utter desperate "don't eat ANYTHING!" which seemed like sheer paranoia…until Reborn let him know Bianchi's favourite method of execution.

"Reborn says she specialises in culinary kills" he continues. "Apparently she can turn anything edible into toxic mush."

"Culinary. Kills?" Hana repeats.

Tsuna nods.

"CULINARY. KILLS?"

"…Yeah."

"CULINARY FREAKIN-"

"I don't think it's going to sound any more rational the more you say it" Tsuna warns, and Yamamoto bursts into laughter.

"Maybe she'll throw poison rice balls at you. I wonder if I could bat them?"

Hana looks upwards as if looking for divine intervention – a move that's quickly becoming habit, and Kyoko giggles.

"Maybe you can talk Hibari into swapping tomorrow and getting him to chase her off" she offers. "He hates people messing with his food."

"I can swap to the extreme!" Sasagawa roars. "An extreme man's stomach is made of iron."

"Oh! Maybe Steam Bun Grenades! I could definitely bat them!"

Tsuna however, just shakes them off. "I don't think we need to go that far guys. Let's just be careful, and no swapping tomorrow."

Everyone seems fine with that – it wasn't meant to be a swap day anyway.

"So what does his sister look like anyway?" Yamamoto asks, and Tsuna falters.

"Hiei…I never thought to ask…Italian?"

"Wow, that's helpful," Hana snaps.

"Well, technically it is" Kyoko argues. "How many foreigners do we really get in Namimori."

"I'll be on the lookout for female Gokudera to the extreme!"

Despite Gokudera's warning, Tsuna manages to eat that evening on the justification that Reborn probably wouldn't let his mother die, and they were eating from the same pot. The same would go for breakfast – except Reborn has chosen to be the sadist Tsuna has long accepted and decided this morning is the perfect time for mafia style tutoring.

Mafia style apparently involves being strapped to dynamite, and is really not helping him concentrate IN THE SLIGHTEST.

Though he gets the feeling Hana would approve.

He chokes on the smoke resulting from his last failed answer (on the plus side, if this becomes a regular thing he's going to be able to handle Gokudera's cigarette smoke a lot easier), and tries to wave the rest away, only to get distracted by a figure standing in the tree outside his window. It's a tiny figure dressed in a cow print onesie, with an afro almost as big as they are, and toting a gun that they shouldn't be physically capable of carrying.

He's…relatively certain it's not Gokudera's sister, but then again, Reborn doesn't exactly look like the world's greatest hitman, so who knows. Foreigners are weird.

"Hiei!" he shrieks. "Reborn! There's someone outside!"

His tutor looks up…and then away.

"Now, the next question is-"

The rest of the sentence is lost by the sound of awkward Japanese.

"Die Reborn!"

Despite the missile launching behemoth on their shoulder, the…hitman? Aims a smaller handheld gun towards the baby. Before he can figure, Tsuna hears a crack, and the hitman and his weapons go crashing to the ground.

"Hiei!"

Tsuna lunges to the window, sighing in relief when they get up.

Moments later, the doorbell rings, and the new arrival is slamming Tsuna's door open.

"It's been a while, huh Reborn! It's me, Lambo!"

Lambo, not Bianchi. So not Gokudera's sister, good to know.

Tsuna turns to Reborn.

"Friend of yours?"

Reborn doesn't even pretend to hear him.

"Remember this formula, all right?"

There's a scream, a lunge, and Tsuna winces as Lambo gets slammed into a wall.

It doesn't get much better for him after that.

A grenade, two crying tantrums, a fractured wall and a brief rundown of a small ranked mafia family later, Tsuna desperately escapes the house before the newest toddler can try his next assassination plot. To his surprise, Gokudera is waiting at the door.

"Tenth!" he greets, falling into a bow. "Please allow me to escort you to school."

"Hiei, there's no need Gokudera" Tsuna insists. "We could have just met on the way."

He winces as Gokudera straightens, fist pumped and fire in his eyes.

"I cannot allow you to fall mercy to my sister!" he yells. "You must not be isolated at any point."

"Oh hey, you had the same idea too Gokudera?"

They both turn, and Tsuna's eyes widen as he takes in Yamamoto running towards them.

"Hiei! Yamamoto?"

The baseball player grins. "You seemed worried yesterday, so thought I'd keep you company this morning. The more the merrier right?"

He gets dynamite brandished in his face for that.

"The Tenth does not need your help Baseball idiot!"

"Hiei! Gokudera, put them down!"

He does. Grudgingly.

"It's cool right?" Yamamoto asks Tsuna directly, and this time, Tsuna notes a touch of apprehension in the taller teens eyes. As if he genuinely doesn't know if his presence is welcome here.

He can't help but smile, and is grateful when that touch fades.

"Sure Yamamoto. The more the merrier. We'll be meeting Kyoko, Brother and Hana on the way too."

"Well, if the Tenth says so" Gokudera mutters, though he sticks tight to Tsuna's right hand side when they start to move.

"So what's your sister like?" Tsuna asks, grasping for conversation.

Gokudera shudders. "She's evil" he growls. "She can turn anything she cooks into Poison Cooking. I don't know how she even feeds herself considering how little restraint she has. When I was little, my family would throw lavish parties in our castle-"

"Hiei? Castle! You're rich?"

"Castle? Are you a Prince?"

The teen jerks in surprise, clearly torn between yelling at Yamamoto or being humble in Tsuna's wake, eventually choosing just to continue.

"I'd been studying the piano since I could walk, but when I was six, I was meant to perform a recital in front of everyone. That was the first time she baked especially for me, a batch of poison cookies."

"What!" Tsuna yelps. "She poisoned her own brother?"

"I don't think the first time was intentional. She can eat her own poison cooking without any effect, so she didn't know what it would do" Gokudera continues. "Of course, the recital was a total wreck, but everyone seemed to think the performance was intentionally unconventional and modern, so my father increased how many I'd do, and insisted she would feed me poison cookies every time – I'd be sick for days."

"That's awful!" Tsuna says, suddenly incredibly grateful that his father had chosen to be 'absent' on the neglectful parent table.

"Wow, your Dad really made you keep eating your sisters cooking even when it made you sick?" Yamamoto replies. "That doesn't seem right."

Gokudera shrugs. "It's half the reason I fled the house before I turned ten" he admits. "I had to eat them so much that even seeing my sister makes me sick. One glance of her pink her and green eyes and I'm useless."

Yamamoto frowns. "Pink hair?"

Gokudera scowls. "Hey, it's not that weird in the mafia Baseball Idiot!"

The other teen shakes his head. "No, no, just…does she have a scorpion tattoo?"

Tsuna blinks in confusion, while Gokudera falters.

"How did you know that?"

Yamamoto points forward. The other two look up-

-And Gokudera immediately collapses as the woman on the bike brakes in front of them. When she removes her helmet, the resemblance to Gokudera is obvious, even though she's clearly 100% Italian blood.

"It's been a while, Hayato" she greets to the downed teen, and smiles at Tsuna. She immediately tosses both him and Yamamoto cans of soda, before continuing to cycle down the road. Yamamoto grabs his, but Tsuna's crashes to the ground, leaking some kind of purple smoke. He gets yanked back by the baseball player, and both stare in shock as a bird crashes to the ground, clearly dead.

"Wow, that must be a really powerful flavour" Yamamoto jokes. "They like their soda strong in Italy."

He then chooses to put his can in his bag, much to Tsuna's dismay.

"Yamamoto! That's dangerous! You have to throw it away!"

"I can't do that! My dad's a sushi chef! You know what he'd say if I threw away perfectly good food? I'm sure I can find a use for this. Anyway, is Gokudera all right?"

Oh, right. Tsuna still had this to deal with…

"Hiei! Gokudera!"

When they reached the corner, Hana took one look at Gokudera carrying Tsuna on his back and immediately glared at Gokudera.

"Tsuna, why are you in the Bomb-Monkey's body?"

Yamamoto chuckles, while Tsuna-Gokudera sighs and Gokudera-Tsuna flails and attempts an awkward bow from his perch.

"I'm sorry I can't impersonate you well enough Tenth!"

"It's okay Gokudera" Tsuna-Gokudera moans. "I wasn't expecting you to anyway."

"We ran into Gokudera's sister on the way" Yamamoto explains. "Turns out Gokudera gets really sick when he sees her, so he got a really bad stomach ache and could barely move. Tsuna figured since it was…what's that word that means the symptoms are only in your head?"

"Psychosomatic" Gokudera-Tsuna groans.

"Right, since it was Psychosomatic, it shouldn't affect him if swapped."

"But since it's mental, it did follow Gokudera into me" Tsuna-Gokudera continues. "But it was a lot easier for Gokudera's body to carry mine, so we're just keeping it up until he recovers."

Gokudera-Tsuna forces his head up and gives a shaky thumbs up. "I'm almost there. I'm sorry to be such a burden Tenth."

Tsuna smiles. "You're not a burden Gokudera."

Kyoko quickly falls in step with them, letting her brother join up with Yamamoto to talk about extreme sacrifices.

"Think of it this way Gokudera" she chimes. "If Bianchi tries anything on the way to school, she'll be attacking you, not Tsuna. You're being a very good bodyguard right now."

Gokudera-Tsuna's face lights up at that chain of thought, and Tsuna-Gokudera gives her a small glare.

"Oh come on" she giggles in whisper. "When a friend feels awful, you should try to cheer them up."

"Did his sister try anything to the extreme?" Ryohei asks Yamamoto.

"She tossed us some really strong drinks" Yamamoto replies. "But I didn't have my bat. Oh man, can batting – that could have been fun."

By the time they make it to school, Gokudera has mostly recovered, and switches back with Tsuna without incident. He's still performing bows and apologising for his uselessness, but Tsuna is starting to realise that's just what Gokudera does, and mostly ignores it as he says goodbye to Brother and the girls, and heads to his locker with Yamamoto and Gokudera.

He's just dropped in his shoes and dumped his back, when it squeals in pain. All three glance down, before he kneels and opens the latch. Lambo bursts out, gasping for air.

"Your bag stinks stupid Tsuna!"

"Hiei! Lambo!"

"Eh, is this your little brother Tsuna?" Yamamoto asks. Tsuna just deflates, plucking the young boy out of his bag and darting outside.

"Lambo, what are you doing here?" he asks, dropping the boy to the ground and kneeling. The kid is only just stopping himself from sniffling.

"R-Reborn shoved me in."

Tsuna winces as Gokudera and Yamamoto quickly join them. Sounds like the Hitman all right.

"Tenth, who is this?" Gokudera asks, brandishing dynamite. "An assassin?"

"Hiei! Gokudera put those away! He's a friend of Reborns…I think."

He turns and stares at Lambo.

"Are you?"

The boy looks utterly offended. "No! I hate stupid Reborn! I'm the Great Lambo! And I'm here to kill him!"

Yamamoto laughs. "It's another player to the Mafia Game! Good luck little guy."

"It's not a game you baseball freak!"

"He's from the Bovino family."

Everyone's head jerks up to see part of the wall fall apart, Reborn rising into view from a seat. Tsuna's jaw drops, and Reborn hops off to land on Yamamoto's shoulder.

"How did you do that?" Tsuna yelps. "Why do you have secret passageways at my school?"

Reborn ignores him, continuing with his earlier comment.

"It's a low ranking familia. As far as I'm aware, we've never met. I don't associate with those beneath me."

Tsuna frowns. Lambo seems very gung how about killing Reborn considering they've never met, and he's not quite sure if Reborn's just egging the kid on. That said, Lambo clearly is a child, unlike the demon-in-toddler-form he currently shares a room with, so it seems rather vindictive.

Before he can even consider calling him out on this though, Lambo is climbing up his frame, grinning like the lunatic Tsuna is starting to realise he is.

"MWHAHAHAHAH REBORN! You fell into my trap!" he roars, kicking off Tsuna with enough force to kick the boy to the ground and throws a grenade Yamamoto's way. Reborn just flicks Yamamoto's ear.

"How about a home run?"

Yamamoto's eyes suddenly flash, quicksilver sharp, and the grenade is caught and immediately thrown out the school gates, where is blows up a chunk of pavement. While Tsuna and Gokudera are busy gaping, Reborn jumps from his perch, turning Leon into a hammer, and slams it into Lambo's afro. The five-year-old goes crashing into the ground.

Reborn turns his attention back to Tsuna.

"Tsuna, classes are starting soon. Get to class."

"B-but- "

"Gotta…stay…calm"

The five-year-old is prying himself from the miniature crater Reborn had left him in, and bursts into tears. Gokudera scowls.

"Oi! What kind of hitman cries like a baby!"

"Gokudera!"

This just makes the kid cry harder, and Tsuna's eyes widen as he suddenly pulls a brightly coloured bazooka out of his hair. The thing is nearly three times the size of Lambo – where the hell did he pull it out?

He doesn't have time to think about it – Lambo is climbing into the gun, and a string pulls the trigger. Bright pink smoke fills the area, and Gokudera crashes into Tsuna.

"Take cover Tenth!" he yells. "There's no telling what this could do."

Yamamoto is also stepping back, though he seems more curious. In seconds, the smoke clears, and all three of them see a tall figure starting to walk towards them.

His hair is stylishly curly, with a lazy expression and a cow print shirt. There's a hand scratching his head, looking a little frustrated.

"Aw man. Guess it's time to start this up."

Tsuna blinks in confusion.

The older teen walked over, squinting in Tsuna's direction before smiling.

"Hello young Tsuna. It's been a while. This is that Lambo, who was once a crybaby."

Wait, what?

"Y-You can artificially age yourself?" Tsuna gasps.

That would actually explain so much about Reborn. Maybe it was another curse, where you could change your age and look like whatever you wanted?

Reborn nips that theory in the bud.

"It's a speciality Bovino weapon known as a Ten-Year-Bazooka" he explains. "It allows the user to swap with themselves ten years into the future. But only for five minutes."

"Wow, that's such a cool toy!" Yamamoto says. "I wish I'd had one of those."

Gokudera oddly enough, just stays silent, staring at Lambo in confusion – as if he'd seen him before but can't quite figure out where.

The Adult Lambo smiles at the teen.

"You never change, do you Yama?"

He then eyes up Reborn, before returning his attention to Tsuna.

"Just so you know, you won't be able to swap with me" he warns. "Gokudera's been insisting I warn you about that whenever I start showing up. There's something about the time travel that makes me immune."

"Oh…good to know?" Tsuna replies, though he can't help but wonder why Gokudera would be so determined to let him know that.

The older Lambo smiles, and returns his attention to toddler hitman.

"Hello Reborn, it's been a while…"

Three minutes later, Gokudera snorted at the beaten-up teen lying on the ground.

"Saw that coming. If Lambo thinks ten years is enough to take on Reborn, he hasn't learned anything."

"Um…should we do something?" Tsuna asks. Gokudera just grabs his arm and starts escorting him towards the school.

"He'll be fine Tenth!" he chimes. "The bazooka will swap him back in a minute anyway, and you shouldn't have to deal with the trifles of a baby hitman like him."

"But- "

Pink smoke blossoms in the courtyard, and Tsuna decides Gokudera might actually have a point, grabbing his bag and running back inside.

When they walk into class, most of the students are staring out the window. Hana however, is standing sentry at the door, glaring at them.

"Tell me those explosions weren't the bomb-monkey."

For the first time that day, Tsuna perks up.

"Actually, it wasn't."

Hana blinks in surprise, while Gokudera scowls.

"Really?"

"Ah no" Yamamoto laughs, walking past. "That was my bad, sorry."

Hana groans, order restored to her world.

"I hate all of you. At least tell me it wasn't on school grounds and the demon-monkey isn't going to take it out of our hides."

Tsuna glances at Yamamoto, who almost seems a little insulted that she could doubt his range.

"Never mind, forget I asked" Hana snapped.

By lunch time, Lambo has been forgotten entirely, with the group convening on the roof for lunch. By this point, Nana has gotten so used to other kids swapping with her son to try her food, she's taken to packing him a huge lunch, knowing full well that between Kyoko, Hana, Ryohei, Yamamoto and new arrivals Gokudera and Reborn, Tsuna will be lucky to eat half of it.

As such, everyone is just a little bit horrified when he opens the container to reveal insects writhing in a purple mass, emitting a hideous odour that brings birds down from the sky. Kyoko risks poking the contents with a chopstick, and stares at the disintegrating end in shock.

"It's best you don't eat that"

On the roof of the small building they were leaning against, Reborn walks into view. "You'll go straight to heaven with one bite."

Gokudera scowls. "Dammit, when did she manage to get her hands on the Tenths lunch?"

Reborn looks towards the door leading to the stairwell.

"Come on out. I know you're there Bianchi."

The door opens, and reveals the same woman Tsuna and the others had spotted earlier. Gokudera immediately collapses, clutching his stomach, while Kyoko, Hana and Ryohei get their first look at the newest assassin.

"Wow, she really does look like Gokudera" Kyoko sighs. "I love her hair."

"She really is pretty huh?" Yamamoto agrees.

"Get a grip Octopus head!" Ryohei roared, trying to yank Gokudera back to his feet. "A real man doesn't let a woman bring him to their knees unless it's an act of love!"

Bianchi doesn't appear effected by the boxer shaking her brother, walking over to the group before glancing up at Reborn. The baby nods at her.

"Ciaossu Bianchi."

A blush stains Bianchi's cheeks.

"Reborn…" she sighs, completely love-struck.

"…Hiei?"

Hana is gaping in horror.

"Oh, you have got to be kidding me."

Bianchi ignores them.

"I've come to take you back Reborn" she says. "Let's do some large-scale jobs again."

"I told you before Bianchi, I have to stay here and train Tsuna."

"TAKE HIM!" Hana snaps. "Trust me, everybody here wants Reborn to leave, I promise."

Bianchi gasps.

"Oh, my poor Reborn" she wails. "That means if the Tenth doesn't die in some horrible accident, Reborn will never be free!"

"WHAT!"

The woman turns, and starts murmuring about coming back if the Tenth died. Tsuna could only watch in shock, before a groan caught his attention.

"Gah! Gokudera!"

For the second time that day, Gokudera found himself completely incapacitated, and Ryohei helped carry him to the nurse's office. He's barely conscious, mumbling something that sounds like apologies to the Tenth. The second they walk out the door, Kyoko grabs Tsuna by the shoulders.

"Switch with me Tsuna" she insists. "It's Home Economics next, and the girls give out their cake to the boys. If she's going to try and poison your food, that'll probably be where she strikes next. If we swap, you can catch her in the act, and if you don't, I know better than to take the cake."

"Kyoko! I object to the extreme!" Ryohei yells. Hana is looming too.

"There's absolutely no point in risking both of you!"

"They're right Kyoko" Tsuna agrees. "Just keep an eye out in class and that'll be enough."

Kyoko shakes her head. "But- "

"Don't worry about it Kyoko" Yamamoto interrupts. "The Mafia Game is all about teamwork. You want to do more, but it won't help right now."

The girl droops, but accepts their answer, and gains a competitive gleam in her eye.

"Fine. But I promise Tsuna, she won't get near a single slice! I won't allow her to sully the glory of cake!"

Tsuna smiles, and Hana chuckles.

"That's my girl."

By the time the girls are prepared to hand out cake, Tsuna is on a knife edge. Gokudera is still in the nurse's office as well, so he's only backed by Yamamoto, who Tsuna is not entirely sure understands that Bianchi is genuinely trying to kill him. Considering most of the class thinks Yamamoto hangs around Tsuna because they saved each other's life, his jokes about the cake being 'to die for' are getting far too many laughs right now.

The doors open, and in flood the girls, all armed with cake. Kyoko has a triumphant grin on her face, and the cake in her hands looks fantastic. Tsuna immediately relaxes.

-Then immediately tenses up when he spots Bianchi darting between the girls, swapping their plates without even noticing. Yamamoto whistles in surprise.

"She's good. Think she does magic tricks too?"

While their classmates descend upon the crushes and begging boys, Yamamoto soon finds himself surrounded, and Kyoko reveals her cake with a flourish.

"Here Tsuna!" she proclaims. "Completely 100% Bianchi free."

Tsuna swallows.

"Um, Kyoko?"

He points at the cake. The girl blinks, looks down, and drops the plate with a shriek.

"HOW?"

Hana glances at her own cake too, scowling at the worm writhing on the surface.

"Okay, I officially hate this woman."

She heads out of the room and dumps the cake in a nearby bin. Kyoko hangs in the doorway, still staring at hers on the ground in frustration.

"She showed up at the last minute" Tsuna admits. "Your cake looked great."

"Huh, I underestimated you"

Tsuna shrieks as Bianchi appears behind him, woman scowling at him.

"A real man would eat anything his girlfriend put in front of him" she warns, pointing at the cake on the ground. "Now I'll have to do something really bad."

Hana scowls at her. "Just give it up you pedo. There's no way Tsuna's going to eat anything you taint."

Bianchi smirks. "Maybe he won't…"

She points a thumb over her shoulder, aiming at something in the room. Tsuna and the girls follow the direction, and pale dramatically.

Yamamoto was surrounded by girls and cake. Purple, smoking cake. One slice was already in his hand.

"Now there's a real man" Bianchi chuckles. "I wanted to make sure I got you, so I swapped out every piece. Too bad, he seemed nice."

Tsuna rushes forward.

"Yamamoto!"

A bullet fired, and Tsuna dropped to the ground. A second later, his clothes burst off.

REBORN! I'LL EAT CAKE WITH MY DYING WILL!

Bianchi grins in delight. Reborn has made absolutely certain his student will eat all her cake, she knew he cared.

Then she pales, because instead of rushing over and eating cake, Tsuna is running over to her, flames burning on his head. Kyoko and Hana quickly step aside, and Bianchi squawks as the teen jumps on her, kissing her fiercely. She's so shocked it makes her disoriented, and struggles to kick him off.

"Reborn! I swear it was him! I'm loyal to you!" she wails, once she's finally free, only to get pinned to the ground by Hana and Kyoko. Normally, pulling two normal civilian girls off would be child's play, but this is taking effort.

"Oh no you don't!" Hana snaps. "I am not playing 'Chase the Body' today."

"You will apologise to all cake lovers everywhere!" Kyoko adds.

She glares at both of them, but pauses when she realises she's wearing a jacket, even though she hadn't been wearing one five seconds ago. She also can't feel her hair, and that's more than a little unnerving.

What's happening in the classroom however, is even weirder.

"Who the hell is that?"

"She's eating Yamamoto's cake!"

"Wow Bianchi, you must really like these. Here, have this one."

Bianchi's jaw drops. She's in that room, currently inhaling poison cake, with an orange Sky flame burning on her forehead.

Her captors are also staring in bemusement.

"So…I'm going to assume you can't get poisoned by your own cooking" Hana muses. "Tsuna wouldn't swap with someone if it was going to put them in danger."

"I'm surprised he even had that much control" Kyoko admits. "That bullet makes thinking hard, he must have been thinking about it just before Reborn shot him."

Bianchi-Tsuna is barely paying attention, too busy staring at the doppelganger clutching their stomach while the flame on her head snuffs out.

"Am I dreaming?" she finally whispers. There's a heavy sigh behind her, and all three women turn to see Reborn staring at Tsuna-Bianchi in irritation.

"I'm afraid not" he says. "This is getting frustrating."

He finally shakes his head, and hops onto Bianchi-Tsuna's head.

"The classroom next door is empty, so let's wait there. Tsuna will give you back your body shortly."

Bianchi nods, still slightly in shock. Once Hana and Kyoko release her, she stumbles to her feet, heading in the direction Reborn points to. She's barely taken more than a few steps, before she hears someone stumbling towards her.

"TENTH!"

Hayato is staggering down the corridor, heading towards her with a half-pained grin. It's the first time in years her brother's been able to look her in the eye, and the act makes her stop in astonishment. The bomber stumbles to a stop in front of her, brandishing a stick of dynamite.

"I'm almost fully recovered Tenth" he insists. "I promise I can handle anything my sister-GAH!"

He collapses at her feet, arms clutching his stomach as Tsuna-Bianchi walks out of the classroom, one hand on their stomach while Yamamoto follows in curiosity. They spot Gokudera on the ground, and Tsuna-Bianchi sags.

"We'd better get him back to the nurse's office…"

When Gokudera wakes up, Kyoko is with him, holding a package in her hands.

"Are you okay?" she asks. Gokudera doesn't answer, struggling to sit up and get out of bed.

"The Tenth!" he yelps. "Is he okay? Did my sister- "

Kyoko raises her hands in an attempt to calm him down. "Tsuna is fine Gokudera! He managed to neutralise all the poison cooking. Everything's okay."

The words let him sag to the mattress in relief, hand over his eyes. When he finally lifts it up, Kyoko is holding out the package – a box wrapped in a skull covered handkerchief. Gokudera loves it immediately.

"I brought you some of the leftover cake. Everyone else has already had some, but I didn't want you to be left out."

Gokudera looks down, but accepts the package gratefully.

"Thank you. I can't believe I was so worthless again. My sister is such a pain, Reborn should just make her leave already."

"You shouldn't say that" Kyoko says. "I'm sure your sister loves you. She just doesn't know how to express it sometimes."

Gokudera scoffs, looking away. "Don't talk as if you understand."

"But I do" Kyoko insists. "I'm a sister too. Just because you're different doesn't mean they don't care."

The teen frowns, choosing the unwrap the box in front of him rather than face the girl at his side.

"I asked Tsuna if I could be the one here" Kyoko admits. "I wanted to ask you to give your sister a chance. Reborn's already said she's going to be staying with the Sawada's for a while, so can you at least try?"

"She's staying with the Tenth!" Gokudera shrieks, arms flailing. "Is Reborn insane! She's gonna- "

"Bianchi's taken a contract with Vongola!" Kyoko quickly interrupts. "So she can be with Reborn every day. She's just wants to be with the man she loves, so she won't do anything now."

Gokudera settles down, though he's still frowning.

"Fine" he chokes out. "I'm not promising anything, but I'll try to play nice."

"Will you spend some time with her?" Kyoko asks, and he laughs.

"You do remember the part where I can't even look at her right?" Gokudera says, finally unwrapping the dessert. Kyoko's smile is a little too coy.

"Well, with your friends, that's not really too much of an issue…"

Gokudera frowns, then freezes when he looks at what's in his hands.

The cake is purple.

Gokudera gulps, and stares at Kyoko. The smile he'd thought was coy…he'd seen it before.

"Big sis?..."

Bianchi-Kyoko smiles and held out her arms. "Won't you hug your sister?"

Gokudera screams.

An hour earlier…

"What do you mean she's going to be my Art and Home Economics tutor!" Tsuna yelps.

From his position in Bianchi's arms, Reborn is smirking. He'd insisted on Tsuna swapping back with Bianchi as soon as they'd gotten her out of the classroom, and then vanished for the rest of the day. Right up until Tsuna was got a paper airplane in his hair telling him to come to the roof, where Reborn had been sitting, drinking coffee, in the arms of the female hitman.

"Since she intends to be in Namimori indefinitely, Vongola has decided to hire Bianchi" he explains.

"I get paid to be with Reborn all day" Bianchi sighs, hugging the body in her arms.

"Given the circumstances, I thought another hitman who could watch over Maman would be a good idea" Reborn continues, ignoring Bianchi's sighs of adoration.

"Watch over?" Hana snaps. "Are you crazy?"

She holds up a hand when she sees the boys beginning to answer.

"Rhetorical!"

"I think it's a great idea!" Kyoko exclaims, and everyone looks at her in horror.

"Kyoko!" Tsuna yelps. "I thought you hated her for wrecking your cake."

"Well, yes" Kyoko admits. "But you made her eat all her poisoned cake, so that seems fair. Besides, She and Gokudera should clearly spend some more time together. It's not right that he can't even look at her - siblings should be close. Maybe he can get over it if he sees her more often."

Ryohei grins, and punches the air.

"I extremely agree! Octopus-head should be a man to the extreme and take care of his sibling."

Tsuna blanches.

"Er, Brother, I don't think Bianchi needs taking care of…"

"Oh don't waste your breath Sawada" Hana sighs. "At least she and your mother have the same views of relationships. They'll probably get along like a house on fire."

That's…more true than Tsuna likes to admit. Yamamoto slings an arm around his shoulder and gives a wave.

"If you're staying, then welcome to the Mafia Game!" he says. "If you like cooking, you'll have to come to my Dad's restaurant sometime. He makes the best sushi in Japan.

Bianchi's eyes narrow in interest, and Tsuna quickly tries to change the subject.

"W-we can do that later" he says. "I'm more worried about Gokudera. If you're going to be staying, he's going to have a problem. He's half dead just from looking at you."

"Gokudera's a hitman" Reborn replies. "He'll have to learn how to deal with weaknesses like this eventually."

Bianchi sighs from her position on the ground.

"I do wish things had gone differently with Hayato. But I can't change the past."

"But you're his sister!" Kyoko insists. "Maybe you made mistakes, but that should still count for something."

"In a perfect world, perhaps it would be. But it's hard to mend fences when he can't even look at me."

Tsuna looks up, and Hana groans.

"Sawada, no."

"But- "

"No!"

An hour later…

Just outside the nurse's office, the group hear Gokudera's scream, and Tsuna-Kyoko winces.

"I think it's extremely going well" Ryohei offers.

"I think the baby's going to have to teach us how to hide a body before sundown" Hana mutters, scribbling in a notebook.

"So, what's it like?" Yamamoto asks, ignoring the loud cries and choosing to eye up the pink haired teen Kyoko was currently possessing. The girl had been running hands through her hair and spinning around the entire time. "Is it weird being in someone older?"

Kyoko-Bianchi pauses from own examination, and glances down at her chest for a moment before shrugging.

"The measurements are weird, and I kind of hope mine don't get this big. It's really awkward" she giggles. "But it's kind of fun, being sexy instead of cute. Think I'd get a discount when I shopped?"

Yamamoto laughs while Hana just rolls her eyes. Her brother is drawn away from the door to frown in her direction.

"I still don't like that Kyoko is the one who swapped to the extreme" Ryohei says, glancing at his sister. Hana scoffs.

"It had to be Kyoko because when Tsuna offered, Pinkie started fantasising about killing him and getting to spend all her time with the baby as the heir. She's got no ill will towards Kyoko, and Gokudera's already learned the hard way not to hurt her."

A moment later, they hear explosions coming inside.

"Of course, that's assuming Bianchi isn't exactly like her little brother and perfectly capable of stopping anyone from thinking rationally" Hana finishes, and the group stare at each other in horror before bolting into the room. All except Hana, who is perfectly happy to stay where she is, writing in her notebook, mindless of the smoke and screams to stop, smirking to herself.

"Don't say I didn't warn you."
