The rain is pouring like a million falling stars . The lightning flashes spookily illuminated the stark leafless trees swaying wildly in the wind , threatening to break apart . Every now and then thunder would boom , light up the sky for a second or two . The once sunny and warm sky now become dark and shadowed.

Tap Tap Tap someone is running under this poor weather , trying to find a shelter to warm up her fragile body . The girl was wearing a hood , trying to cover every inches of her body from the icy wind . The path she choose was not an easy one , as you can see from the torn hood and injured limbs , but the girl keep running and running . To the direction of Vongola HQ .

Everyone in the room is either talking or laughing , creating a warm atmosphere , except for a certain skylark and pineapple head glaring at each other . They seems to not be affected by the harsh weather outside . Being a kind person as he was , Yammamoto Takeshi pray that no one stay outside under this weather .

Turning his view from the window , he look around the room , or living room to be exact . All of the Vongola guardian has live together after they inherit the Vongola rings from the previous generation .However Hibari Kyoya , the cloud guardian who dislike crowding live near the HQ in a japanese style house . Yammamoto is kind of glad that Tsuna ask everyone to live together in this mansion so that they can protect each other when other famiglia attack .

Even though they are all living together , he couldn't help but feel lonely . It's not that everyone is ignoring him , its just that every guardian had their partner or lover . Since Tsuna had become the Vongola Decimo , he married Kyoko , while Gokudera and Haru are dating , Ryohei had married long ago with Hana , Mukuro had engage with Chrome months ago and their wedding bell are close , Lambo has Basil or Spanner as his playmate , even THE cold and unapproachable Hibari has I-pin as his partner.

Ma never mind , I can always play with Lambo thought Yammamoto as he smile .

THUD THUD THUD The sudden loud bangs echoed through the living room and everyone stop their activities , wondering if they heard wrong .

THUD THUD THUD THUD THUD THUD and confirm that there is someone at the door .

' I wonder who will visit under this kind of weather ? ' Kyoko said out loud as she prepared to go and open the main door .

' Ah Kyoko wait a minute , it may be some kind of sudden attack from the enemy . ' Hana is worried that her friend will get hurt .

' But outside is raining heavily , what if someone need our help ? ' Being a soft-hearted person she is , she can't ignore someone who need help , even if it is the enemy .

' But - ' Hana wasn't able to finish her sentence when the banging sound is heard again .

THUD THUD THUD THUD

' I'll go and see ' Yammamoto smiled and get up and walks towards the corridor that leds to the main door .

' Be careful ' came Kyoko voice and it echoed through the corridor towards the main door .

thud thud thud the banging is softer this time as Yammamoto approched the huge double doors ,he couldn't help but wonder if the intruder has no strength left . One hand on the door knob , the other on his katana , he pulled the heavy mass , prepared for any attack .

What he didn't prepared was a girl fall towards him as he open the door . A wet , hooded figure and injured limbs .

' RYOHEI ! ' shouted Yammamoto immediately as he carry the hooded figure to the closest bed he could find which happen to be the nursery . Then the Vongola Sun guardian came rushing along with the rest of the people .

And that was how the Vongola famiglia has a new member .

The light ray from the outside shone through the window onto the white bedsheets . The skys are clear , light pierce through the clouds like soft cotton , free from dark clouds and the the cheerful sound of birds chirpping could be heard .

Inside the room , on the white bed , a sleeping figure could be seen .There are also two girls busy cleaning the girl's body and bandange the injuries she suffered . They also change her clothes into clean one and patches up the torn cloak she was wearing when she first arrive here .

' Ohaiyou , Kyoko-chan , Haru-chan , how is the girl ? ' asked Hana .

' Ohaiyou , Hana-chan ' replied Haru cheerfully as she wiped the dirt out of the girl's hand .

' Ohaiyou , Hana . It seem like the girl catch a cold from the rain the other night , I hope she recover soon . ' came Kyoko answer as she was worry about the condition of the girl on the bed .

' Don't be so worry , Kyoko-chan . It's just a cold , not something too serious . ' said Haru .

' Yeah , with your care , I'm sure she will be off the bed in a short time . ' Hana said assured Kyoko .

They continue and chat a little bit but stop when the girl on the bed stirred . The girl slowly opened her eyes and scanned the unfamiliar place she was in . Where am I . thought the girl when she spotted three female standing by her bed and look at her worriedly .

' Whe - ' she couldn't finish her sentence because her throat are too dry and she immediately start coughing .

Kyoko who is closer to the table pour a glass of water and hand it over to her . The girl quickly gulped down the water to eased the pain on her throat .

' Thank you ' came a shy reply from the girl . The girl's voice is small but they managed to hear it . They smiled knowing the girl was okay now .

' You're welcome . How do you feel ? Does anywhere hurt ? Are you hungry ? ' Haru bombared the girl with the question .

' ... Em...' the girl doesn't know how to reply and can only stared at her with wide eyes .

' Calm down Haru-chan ' so the girl name is Haru .

' I'm Kyoko Sawada , what is your name ? ' and this girl with soft voice and beautiful face is Kyoko...ahh !...I forgot to answer her questions !

' N..Nice to meet you , my name is Sienna . ' I manage to say those words with my sore throat .

' I'm Hana Sasagawa ' she's so mature , like a big sister ' And I'm Haru Miura ' she's so hyper but kind of cute , thought Sienna as she looked at them and smiled .

' Let's go and eat breakfast with the others , Sienna .' the one named Haru gently pull me from the bed and led me to the dining room followed by Hana And Kyoko chatting behind .

' Arghhhh ... ' Yammamoto yawn as he walked down the stair . Yesterday he was thinking about the girl he carried to the nursery all night and has neglected his sleep , why is a girl doing outside on a weather like that ? , he was deep in thought and did not notice a certain brunette was looking at him .

' Yammamoto ? Didn't sleep well ? You look tired . ' Tsuna asked while looking up from the newspaper that he holding .

' Kufufufu...Must be thinking about the girl yesterday . ' came a teasing reply from Mukuro .

' Oh ? You already care for her ? You don't even know her name . ' Gokudera continue to say while grinning .

' Maa maa , I am just worry about her , after all she had to endured the storm last night , right ? ' Yammamoto defend himself while taking a seat across from Chrome .

' That's right , I am also concern about her ... ' Tsuna said .

' Jyuudaime , I'm sure that Haru will bring her here if the girl wake up . ' assured Gokudera to a worry looking Tsuna .

As if the girls can hear their conversaton , they appeared at the dining hall soon after Gokudera finish his sentence . Yammamoto heard some voices so he assume that the girls are coming . He lift his head to greet the girls but was shocked to see a girl with waist-long pale blue hair with them . Sienna is wearing a simple white strapped dress that end until her thigh , and a dark blue short that shows her long legs . She skin tone was pale , probably paler than Chrome's , but her cheeks had a blush of healthy pink .

She instantly captured Yammamoto's eyes but quickly turn away , blushing . She is beautiful . Yammamoto thought in mind , and did't realise he'd been staring at her for a while if Chrome did not gently kicking his leg and Mukuro's ' Kufufufu ' with an amused eyes .

Entering the dining hall , Kyoko took a seat beside Tsuna while Haru took her seat beside Gokudera . Hana pull Sienna to a seat beside her which coincidencely was next to Yammamoto . Chrome gave her a gentle smile when Sienna seated .

Phew... Glad that Hana is beside me . thought Sienna after she returned Chrome a cheerful smile .

' Okay , since Sienna is unfamiliar with us , so how about we introduced ourself to her ? ' say Kyoko while looking at everyone .

' Well , I'm Sawada Tsunayoshi ' Sawada ? Same as Kyoko , are they siblings ? ' Also Vongola Decimo and Kyoko's husband . ' he ended it with a smile . So he is the head of this Famiglia ? He doesn't look strong with his warm brown eyes and hair spiked over like a bush . And Kyoko is married to him , they look like a kind couple but not a mafia boss . Sienna concluded .

' I'm Gokudera Hayato , Jyuudaime's right-hand-man and Vongola Storm Guardian . ' the one with silver hair speaks . He look more like a mafia ...

' Sasagawa Ryohei ! To the extreme !' the one with short white hair spoke . ...Extreme...?

'...?...' Sienna expression clearly show that she doesn't understand .

' Sorry , Sienna . I'll introduce him to you . ' Hana said while trying to keep her husband to shut up . ' Hmnph ...' and with a bread in Ryohei's mouth , she succeed .

' Hai ~ so troublesome . He's Sasagawa Ryohei and Vongola Sun Guardian . And I'm married to him . ' Hana ended with a happy and content expression .

' Nihao , I'm I-pin and he is Kyoya Hibari , the Vongola Cloud Guardian , nice to meet you . ' she pointed to a man next to her and say . She has a chinese essence , but she really is pretty .

' Hn ' was Hibari's answer and a signature glare . ...c..cold... Sienna couldn't help but shiver a bit .

' I'm Lambo , the Vongola Lighting Guardian ' came a short and boring reply from a teen . He's young .

'Kufufufu ... don't mind Lambo , he's just upset there has no sweets for him . By the way , I'm Mukuro Rokudo , the Mist Guardian and this here is my fiance , Chrome Dokuro .' a man with unusual hairstyle said .

' Nice to meet you .' beside him a women with shoulder long violet hair speaks up , she has a soft voice .

' Yo , I'm Yammamoto Takeshi , Tsuna's left-hand-man and Vongola Rain Guardian . Nice to have you here . ' a man with a scar on his chin said .

Sienna stand up and bow a little to show her sincerity . ' Nice to meet you all , I'm Sienna .'

Sienna , what a nice name , Yammamoto thinks as he eye the girl beside him .

' Sienna , let's not be so formal , have a seat .' Tsuna kindly said . ' There are other people from our famiglia which yet to meet you , but I think you will meet them soon ...'

'Lambo is hungry .' Lambo cut in and say . With that he munch down a piece of sandwich in front of him and proceed to take another one , which turn out to be Gokudera's . Then , a fight between them started just for a sandwich . Tsuna trying to stop the fight but failed , Haru and Kyoko chatting happily , Hibari and I-pin quietly left soon after , Chrome shared her excitement about her wedding to Hana . Basicaly , the dining hall is a mess .

' Aha , sorry for all the noise . It is our daily routine . ' Yammamoto say it like nothing .

' Daily routine ?! ' Sienna is shocked , this is daily routine? . ' Your famiglia is quite ... full of energy . ' She manage to find a proper word to say .

' Ahahaha , our family is lively ' no , its disasterous . ' By the way , why are you doing outside in that weather yesterday ? ' Crap , what should I say ? They seem nice , I don't want to lie to them ...

Yammamoto notice that Sienna was uncomfortable with the question so he quickly reply ' Maa if its something important that you can't say , that don't force yourself to say it . '

Sienna is glad that Yammamoto could understand her and didn't force her to say it .

' Thank you . ' Sienna smiled to him . To her oblivious , she didn't notice the light shade of pink on Yammamoto's face as he quickly turn away from her .

' Yammamoto ? What's wrong ? Why did you suddenly turn away ? ' Sienna innocently ask .

' N..Nothing . ' Damn it , why did I stutter ?

Just like that , Yammamoto didn't realise he was starting to fall for the beautiful bluenette next to him . And neither did Sienna know she will be the same fo a certain rain guardian .
