I gritted my teeth "The Varia" every head snapped my way "Vongola assassination squad, to goddamn smart to fall for fake rings"

"Aemi? I thought you were staying away from Tsuna while he was angry?" Yamamoto cried. I ignored them.

"So which one of you figured it out? 'Genius' Prince the Ripper? Levi 'The boss' right hand man'? Mammon the greedy ass bastard? Or was it your freaking idiot boss Xanxus?" I said as I held my hand up beside my hand to block the blow that I knew Xanxus had thrown at me.

"Long time no see 'Onii-sama' " I spat venomously. "What kind of 'activities' have you been up to lately? Dismembered any nice people recently? Have you gotten any better at maiming people? I remember you always used to fail at maiming me, well of course you still fail at maiming then don't you?" I said throwing my arms wide. "How could you have succeeded? I'm still here aren't I?"

I snorted with disgust "Is this another attempt on my life, or is it an attempt on all of our lives this time? Wouldn't that be a change in pace, instead of those 60 odd assassination attempts in my sleep, I think it'll be a real treat to have someone try and murder me while I'm awake instead" I sat on the edge of the building across from them.

'Ushishishi, Battle Principessa' I heard Bel mutter from across the street.

"Don't even try it, 'My Prince' or else I'll chop of your 'Royal Jewels' got it?" The evil sadistic bastard that he is, he continued to laugh "Oh wow, Belphegor's a masochist, as if no one knew that already, you know he doesn't just start laughing whenever he starts bleeding, oh wait, HE DOES" I suppressed a snort "really, just get our favourite sadistic tonfa wielding prefect in with Prince the Ripper here and they'd have a lot of fun"

Tsuna and the rest of our family were staring at me. "Oh please, I was raised by them for important formative teenage years what did you expect?" Gokudera glared at me.

"You called juudaime's enemy Onii-sama, obviously you're on their side dammit" I huffed before jumping off the edge of the building and landing beside Tsuna.

"I will have you know that I am a 'juudaime' candidate as well, in fact, you might call Tsuna my right hand man, Ahou-dera" Tsuna rolled his eyes and Gokudera's jaw dropped "For that matter you could probably call me Tsuna's right hand woman"

"Stop making fun of him Aemi-nee-chan" I winced at the cold tone in Tsuna's voice.

"Imouto…" I said softly. Finally I tore my eyes away even though it hurt me too let Tsuna still be angry at me.

Moments later, Gokudera finally pulled himself out of his stupor.

"Wait…who are you?" I pretend pouted.

"Really? My own family doesn't know who I am? Oh woe is me, how will I ever survive?" I turned to the Varia who were busy trying not to laugh their heads off. "Hey Xanxus, I changed my mind, I'll take you up on your offer to be Boss together, at least you guys know who I am"

"Too late trash, I already got a replacement" I pretend saluted him.

"Aye Aye captain," I turned back to Gokudera and genuinely smiled. I offered him my hand to shake "Sawada Aemi, Tsuna's twin sister, also the person with whom Tsuna will be sharing the role of boss with eventually" He kind of amazedly took my hand and shook it. He opened his mouth to respond and I held up my hand to stop him "I've been living with CEDEF for two years, I know exactly who you all are, You are 'Smoking Bomb' Hayato, or Hayato Gokudera, your elder sister is Poison Scorpion Bianchi, and you use bombs as weaponry, I have more details but I don't feel like discussing them in front of the Varia"

"Che, We already knew all that trash"

"I know Xanxus that's why I was willing to say it in front of you" I said looking over my shoulder at him "what do you think I am? An idiot? Che" He reddened with anger

"Well, have your idiot father explain what the rules for the battles are, seeing as you showed up late yourself" He said taking his only available remaining pride.

"I already know what the rules are, I got a letter as well, if you had forgotten I've been considered a likely boss candidate my whole life, where as even Tsuna wasn't considered possible until I told them I wouldn't be boss without him" I raised an eyebrow at them "Best of Luck in the battles" I finished calmly.

"Hmph, we won't need luck to beat you trash" Xanxus retorted I gasped.

"Oh, I'm sorry did you misunderstand me? I meant best of luck so that when you lose you'll fall on your ass instead of your head; heaven knows you have too few brain cells to begin with" I raised an eyebrow silently challenging him to retort to that.

"Yeah and hell knows you were born with none" I rolled my eyes at his stupid retort "We're leaving"

"I think I have enough brain to figure that out without an announcement, thank you so much Captain Obvious, what will you announce next? Your lack of enough common sense that keeps you from running away screaming like a girl?" His back tensed but he jumped away anyways.

"Good job Decimo! I could seriously imagine you being boss with Juudaime!" Gokudera said clapping me on the back.

"Takeshi-kun" I said faintly.

"Yes Aemi-chan?"

"Catch me, I think I'm going to fall over" He grabbed me as soon as possible once he realized that I was swaying on my feet and therefore, not kidding.

There was a silent question on everybody's faces, 'How can you stand up to Xanxus like that then nearly faint afterwards?' "Sorry about that. Battle Aemi has made her first appearance." I paused before breathing to explain. "I've sort of created this battle ready alter ego, who I call Battle Aemi, Battle Aemi can take care of anything, can burn with the best of them, real Aemi falls over from accumulated stress afterwards" I rubbed my temples "The Varia of course knows about my two different personalities after living with me for half a year thus the reason Bel referred to me as 'Battle Principessa' "

Gokudera snorted as my newly won respect disappeared from his eyes. Ryohei too looked like he was trying not to laugh but Takeshi-san just smiled, and I could hear him mutter under his breath 'cute'.
