Here's a new story I just thought of, it's just an idea though so it really depends on whether you the readers enjoy it enough so I know whether or not it's worth continuing.

I do not own Katekyo Hitman Reborn/How to Train Your Dragon or any of the characters. EnjoyXD

When Worlds Collide

Chapter one

Verde's lab

''Tell me this, why is it whenever you tell me you've got an idea it ends up to be something to embarrass me?'' asked a girl to the demonic infant who was Reborn, who had a sadist smile on his face.

The girl had long brown hair that went to the middle of her back with a fringe covering the entire right side of her face. To match her hair, the girl had two brown eyes that had been outlined with (waterproof) eyeliner to make them stand out, even though only one eye was visible. She was wearing a long black vest top along with a light gray sleeveless jacket(1), which might as well off been a short dress, with beige arm warmers going just above her elbows with bands around them keeping them in place(2) and white short crop trousers. Currently, the girl wasn't wearing any shoes.

Reborn started to chuckle ''Calm down, Dame-Tsuna, this isn't so bad and if it helps I think this look suits you.'' Not helping with Tsuna's dismay.

Earlier that day

Tsuna was walking home from school thinking over what was just announced at said school.

'Some of the boys in my class have to dress up as girls for a fund raiser and Reborn has been telling me that some mafia has hired assassins to do me in. Why does my life suck?' Tsuna thought with dismay.

Walking to his front door, Tsuna felt something hit his head, hard, thus knocking him out. Yep, his life sucked.

A few hours after being knocked out, the brunette boy woke up in what he thought looked like a lab, in which case he would be correct.

''Where am I? A lab?'' Tsuna wondered, while looking around finding himself lying on a sofa.

''Verde's lab to be precise, Dame-Tsuna.'' said a familiar, high-pitched voice.

Whipping his head around to the source of the voice ''Reborn! Why am I here?'' the brunette boy asked/demanded his annoying demonic infant hitman tutor.

Smirking, Reborn replied ''I have an idea to hide you, from the assassins sent to kill you, right under their noses. So to answer your question, you are here to get… a make-over.''

That said, the make-over begun.

Present

So in summary, Tsuna was walking home when Reborn got someone to knock him out to take him to Verde's lab, for some reason, to get a make-over so he looked like a girl, which in fairness isn't hard since Tsuna looks feminine as a boy anyway, to hide him from the assassins but so he can go to school anyway.

''I'm quite surprised we didn't really need to do much. A little eye make-up, brushing and washing your hair, putting you in some girly looking clothes with padding in the chest to make you look like you have under-developed breasts and voila, one girl Dame-Tsuna. Also, it's quite surprising that your natural hair is straight and this long.'' Reborn said, looking over Tsuna.

Shrugging, Tsuna said ''I've always had straight hair but I got bed head really easily so everyone thought my hair was naturally spiky and since I get up late there's no time to brush my hair down. In fact all that time with my bed head made it seem as though my hair didn't need cutting so it being so long doesn't surprise me. Besides, my long hair helps make me long like a girl doesn't it?''

Reborn nodded ''By the way, Verde wants to see you, and before you ask, no I don't know way. Go down the hall to your left, when you leave the room, he's in his techno-lab which is the door at the end of the hall.'' That said, Reborn kicked Tsuna out of the room to go find Verde.

Walking down the hall, the brunette was thinking of different reasons as to why Verde would possibly want to see him. Reaching the door, Tsuna knocked and upon hearing a quiet 'come in' entered the lab.

Verde was sitting at a computer beside which he was using to program a black version of the Ten Year Bazooka. This goes without saying whatever Verde wanted with Tsuna, or wanted him to do, was not going to be good for him (Tsuna).

Turning around Verde started to talk ''Good to see you listened to Reborn and didn't get lost, Tsunayoshi, and that you're transformation went well. I must admit you're not so bad to look at.'' Looking at the brunette with an observing look.

Feeling awkward, said brunette looked at the floor ''So what is it you want to see me about?'' he asked.

Picking up the now programmed bazooka, Verde replied ''This is why I wanted to see you. I've just made this bazooka under the same technological build up as the Ten Year Bazooka, in theory, when shot with this you should be sent to another dimension or time line. However, I do not know how long one would be sent to said other dimension/time line for, that's where you come in. I am going to shot with this bazooka and see however long it takes for you to come back and if you're not back within the day tomorrow then I shall reprogram the bazooka to bring back whoever was shot by it and place a time limit on it myself.''

Now though that explanation, Tsuna picked up on the crucial words in that whole dialogue 'in theory'. 'This means something bad is going to happen to me once I'm shot by that bazooka. I'm basically a guinea-pig! Why does life hate me?' Tsuna thought in dismay, not noticing the infant aim the bazooka at him.

Snapping out of his self pitying thoughts, the guinea-pig, noticed too late and was shot by the bazooka before he could act.

Fortunately, or unfortunately, said guinea-pig had disappeared before he could see the warning on the computer meaning that he'd be wherever he was sent for a little longer than he or Verde expected.

''Shit! Reborn's not going to give me a second of peace when he finds out what happened to Tsunayoshi.'' Verde cursed to himself.

''What's happened to Tsunayoshi?'' asked Reborn, who appeared out of nowhere, with a serious voice.

'Shit!' was the last thing Verde thought before he explained what happened to Reborn.

(1) = look up haori on google it looks like that

(2) = think of Yoruichi's arm warmers from when she was fighting Soi-Fon
