Again… here's another story hehehe
I just can't get over this starting a new story thing
It's just so exciting!

just remove the asterisks (*)

So this story is inspired by all the AU Sawada Twin stories as well as the thiefTsuna stories that I've read/favorited. Though I may accidentally use ideas from said stories, they're completely unintentional and I'll try and vary differently from the stories as much as possible. I'll also try and not go canon as much as possible too but will need to in order to fill plot holes and stuff. Also, I also borrowed the idea of the phantom thief from DNAngel but just the basic idea.

I'll make up the rest haha
Hope you enjoy!
Saa, we start!

Disclaimer: I don't own KHR and I already explained everything else hahaha

Summary:

The Sawada Twins are known to be polar opposites of each other. Sawada 'Tsuna' Tsunayoshi is poor in school and athletics and is bullied because of these factors whereas his older twin brother, Sawada 'Katsu' Katsuro, is athletic, has average grades and is liked by many people. It's because of these qualities that he is considered to be the one who'll inherit the Vongola Crown as Vongola Decimo. Tsuna isn't bothered by this however since he's got more important things to deal with than the mafia or its inheritance issues.

In truth, he is the phantom thief known as Kaitou Cache (cache (kah-sh) = hidden/cover/mask in French) and at night, he goes around stealing jewels and art pieces as he outwits the police and evidently makes the public think of him as a figment of the imagination because camera crews and photographers are never able to get a clear image of the thief; only the shadow or figure can be seen. But what they all don't know is the very reason why he started to steal in the first place.

***** I tuned this chapter up and will do so with the other chapters up to Chapter 6: Target 5 *****
mainly because I'm trying to change up my writing style a bit and fix things that seem to annoy people XP
and there are things that I want to fix sooo badly... ish

Prologue: My Double Life

The big spotlights, the sirens, the crowd of policemen lined up around the prize... It was all sort of a thrill to him as he awaited his chance to strike, yet at the same time, he felt that it was all unnecessary, not that he had ever planned on having the police or even reporters here on site while he was trying to do his job. Behind the see through mask that the boy wore, his eyes glowed a dim orange due to the special contacts that the boy wore. Built into his contacts was a computer like screen that was visible only in front of his eyes and glanced at the time. "8:50 huh... Oi, are your preparations almost done?" The boy asked into a bluetooth as he watched the policemen move from the vent he was in.

"A-Almost, but the museum security is tighter than you'd think." The voice said back.

"Well, if that man doesn't show up himself, then his goons would probably almost be here, so we have to get in and out as fast as possible." He whispered.

"I'm sorry, Tsuna-kun but we're going as fast as we can. Wait, I got it!" the voice said as the lights all went out immediately after.

"You're the best, 51, gotta go and I told you not to say my name during communication!" The boy, Sawada Tsunayoshi, quickly scolded as he pushed open the vent door. and glanced around. He heard a quick sorry before he jumped out quietly and looked towards the large group of policemen. From his pocket, he took out a grenade that only made a bright flash when it exploded and pulled the trigger before tossing it down a hall where it went off.

"Men, he's infiltrated! Keep your guard up and split up down the halls!" the inspector Nakajima Eisuke, who was in charge of the guarding of the priceless crystal vase that sat in the middle of the room, exclaimed. The men all nodded and did as they were told but even with the decline in forces, there were still many present. Tsuna guessed about 25. 'This is going to be tougher than I thought.' Tsuna smirked and pulled the hood of his cloak over his head. He immediately decided that this was a chance to do something that he never usually does.

He took a deep breath in before diving straight into the crowd of policemen. He zipped in between them swiftly, trying his best not to touch any of them but it didn't stop them from noticing his movements. "He's running towards the vase!" One of the men exclaimed as they group then shifted and shuffled, trying to find the thief but found it difficult in the dark.

"Someone catch him, he's running around our legs!" On top of the darkness, their shuffling made it harder for them to try and catch him as he brushed past their legs. They all just ended up hitting and bumping into one another. Tsuna wasn't bothered by the darkness for his contact lenses also allowed him to see clearly through the darkness. After he was close enough, he leaped through the air horizontally and hooked the vase. He evaded the whipping hands that tried to grab hold of him and used their shoulders as a means to jump over the crowd of men. He then landed behind them and ran out towards the main entrance hall. "He got the vase, after him!" Nakajima exclaimed and led the pack.

"Phew, that went better than I thought." Tsuna breathed as he looked at the vase in his hands and tried to examine it, but his examining time was cut short as people started to come in front of him as well as behind, easily surrounding the boy. "I forgot that they split up into the halls..." Tsuna sighed and stopped running as they drew closer and closer. Many of them had their batons out and Tsuna was wary of them. He knew that they weren't afraid to get violent with a criminal, which he technically was and he made note that they also carried tazers and guns in their belts as well.

"We got you now!" the chief from behind him exclaimed as the men that were quicker than the others had reached the thief and immediately attacked him, but at the same time were conscious of the vase, which left them at a disadvantage. Tsuna didn't panic however as he dodged their blows before ducking into one of the side rooms that was on the left wall and disappeared through the window. The group of policemen followed him, crowded the window space and searched around but couldn't find him anywhere as the boy disappeared without a trace.

"We're on the third floor, where could he have gone?" Nakajima shook with anger.

"Suicide?" one of the others suggested.

"Are you stupid? The brat wouldn't do that! If Kaitou Cache was suicidal, then he would've thrown himself off the roof a long time ago, not here stealing precious items. Plus, he's nowhere in sight!"

"Inspector look!" Another man exclaimed from the back.

"What is it?" They all looked straight and found the crystal vase hanging in front of them on a branch with a familiar tag taped to it.

"Good Evening Inspector, I decided to give this back... ciao for now!" The card read. "He's messing with us! What does he go stealing for anyways?" He exclaimed, boiling in anger now. "He's just wasting time now, if he's just going to return the item then why bother stealing!" This has happened many times in the past since Kaitou Cache had made his appearance and it hadn't only happened in Japan but oddly enough, all over the world.

"At least we got it back." The others tried to reassure their boss.

"Yeah, so that means it's our victory." Nakajima laughed.

"But we have to get the vase first." Someone cut the victory short as they stared at the vase dangling dangerously.

"Gaaahh, get it, get it! It's priceless! Worth more than our salaries combined!" They all then scrambled to save the artwork.

Meanwhile, on the roof top, Tsuna sighed and leaned against the fence. He pulled off his hood and mask and looked at the time again. It was about 9:30 now and he was just as annoyed as the inspector down below. Just moments ago as he ran into the room, he had found a note addressed to him stuck inside the vase and read it:

Dearest Kaitou-kun,

I'm glad to know you are reading this letter, which would also mean that you are safe.
Anyways, I'd just like to thank you for going through the trouble of finding this vase for us and uncovering its hidden secret, or there lack of.
But let's not worry about such trivial details. Let us focus on how the next time you attempt to get in my way, you won't be around long enough to see the next daybreak.
I don't enjoy threatening much~ But if it must be done, it must be done~
Just don't let it happen again ( ^v^ )

Wishing you safety till the next time we meet,
Gesso

Tsuna just cringed at the mention of that name. He was contradicting himself as he wrote the letter; it was especially noticeable when you know the personality of said Gesso, but the brunette got the gist of the message. "Tsuna-kun, Tsuna-kun, are you alright?" a voice called worriedly from his wristwatch.

"Yeah, I'm fine and I told you not to call me by my name just in case we were being overheard."

"Ah, gomen... eto... Cache-kun." The voice said. Kaitou Cache was the alias that was given unto Tsuna's alternative self though he didn't really know exactly how this came to be. At his school, he'd heard that it was the reporters' doing as they justified it as not being able to get a good glimpse of the thief and thus named him accordingly, naming him the French word for 'Hidden' or 'Masked' – Cache, the phantom thief.

"So how was the mission?" the other boy asked.

"It turned out to be a fake. I got a note from Gesso, and he seemed to have been watching from a distance if he was even there."

"Are you alright? Did they do anything?" the other sounded even more worried, if possible.

"Nothing that I'm aware of, so it's all fine for now. Well, I'll be seeing you tomorrow, I have to get home." Tsuna said, taking note of the time again.

"Alright, get home safe. We'll be waiting to hear from you later."

"Ha, ha, I'll remember this time." Tsuna joked and jumped off the roof of his heist location.

. . . . . . . . . . . . . . .

"Tadaima!" Tsuna called as he walked through the entrance to his home. He had quickly changed out of his Kaitou Cache outfit and changed back into his school uniform back in the park. When he entered, he found his mother sitting in the living room and watching the news. It was a reporter who had been at the museum scene and was announcing the 'failure' of Cache's heist.

"Ah Tsu-kun look. Kaitou-kun was at the museum today." Nana said with an excited tone. "It must be exciting being him." She fantasized his kind of life.

"I'm sure it must be okaa-san." Tsuna sweatdropped but felt sort of relieved that his mother didn't see his alternative self as a bad person.

"Though it must only be a big game to him. Stealing all the time but giving back his prize later." She seemed puzzled about this fact.

"I'm sure there's a good reason, okaa-san." Of course he had a good reason to steal items. It wasn't like he enjoyed doing it... alright, that was a lie, since he did sort of enjoy the thrill of being chased and outwitting the police every time. But he didn't like to steal, if there was any other way to get the items other than buying them, then he would do it but it was impossible and his justification of his actions was just too complicated to explain to people who knew nothing of the secrets held by the items that he, as well as a certain Gesso, sought.

"So did anything happen while I was gone?" Tsuna smiled as his mom shut the tv off.

"Katchan got a new tutor!" she said in a bubbly manner.

"Katsu got a tutor? For what reason?" If anything, Tsuna wondered why he wasn't asked to get a tutor. Of course, he didn't actually need one but it was for the sake of his fake persona that he presented to society. To cover up for his other identity, he had to put up an act to lessen the chance of people connecting him to Cache; though it was highly unlikely that people would actually trace Cache to him at all. It was all just precautionary.

"There was a flyer this morning so I decided to give them a call. He came in right after you left."

"Ciaossu~" said another voice that Tsuna didn't seem to recognize. Tsuna turned towards the stairs and was met with a baby in a black suit and fedora and he inwardly widened his eyes but was careful not to show his shock to the other and continued to feign obliviousness.

"Ah, Reborn-kun, this is my other son that I had mentioned before." Nana introduced. "Tsu-kun, this is Reborn-kun."

"He must be the dame one." Tsuna felt a vein throb in his forehead but didn't comment on that. "So the great Reborn does his research."

"You're a tutor? Did they lift the age minimum?" The boy tried to live up to his dame name and bent down to meet the infant's eye level.

"Of course not, baka. Why on earth would they ever license a real baby..." The brunette looked up the stairs and saw his older twin brother coming down. Sawada 'Katsu' Katsuro was Tsuna's older brother and 'was better' at many things than 'Tsuna' was. This included learning and sports.

"There goes Katchan with his jokes again." Nana laughed ignoring her son's harsh tone.

"Kaa-san, I told you to stop calling me that childish nickname, it's embarrassing." Katsu said in a heartless tone, but Nana paid no mind to it and walked into the kitchen.

"You should speak respectfully towards your mother." Reborn, with a green hammer at hand, whacked the older twin in the head and caused him to fall to his knees and grip his head.

"Itai! That hurts!" Katsu said sourly, narrowing his eyes at the baby.

"You three should head off to bed now, it's getting late." Nana warned from the kitchen. "Reborn-chan will be staying in Katchan's room, Tsu-kun." She informed her youngest.

"I'll take care of them, mama." Reborn called and looked at the twins. "You heard her, get up stairs. And we have to talk to you afterwards." Reborn referenced to the younger twin. Tsuna didn't have a good feeling about this but nodded regardless. He followed his older brother up the stairs and got ready to sleep.

Reborn looked at the pair and watched them carefully. From first impressions alone, the baby hitman could easily tell which twin was better suited to be the Vongola Decimo but if he'd learned anything from his experiences, it was not to judge a book by his cover and this was as good a time as any to not judge a twin by what he expresses outwardly. He had been examining the younger twin the moment he had come in and the way he spoke with his mother was different from what his body language was showing. It had also contradicted what his brother and mother had said about him as the boy looked pretty worn out when he had arrived home, as if he had just done something strenuous.

Also, earlier that day when he had first arrived, he had asked mama where Tsuna had been, and she had told him that he normally leaves earlier than his older brother. She had also mentioned that there were a few times when he'd return home late. Tsuna had excused those days as having to stay at school late to work on something but Reborn had a feeling that something was up and he was going to find out what it was one way or another.

So how was it?
What do you think? Worth writing or should I just give up on this?
Anything I need to fix? Tell me and I'll fix it XDDD
I know I was pretty vague about stuff

And I didn't give descriptions on how the twins looked
But that's what the pictures are for haha
So go check them out and pass on the feedback ^^
Thanks for stickin around
Owari desu~
