Meeting the Straw Hats

When Ace and Law decided to take this job and go undercover they didn't expect to grow attached to the mafia families at all, they all treated them like one of their own and it made them feel bad because they were trying to find something they could use against them. Those two were after all two undercover against from the world government. But a job was a job and both of them would fulfill it at all costs.

Through some miracle they had successfully invaded the Whitebeard Family, which was lead by Edward Newgate. They had met Shanks as well, the head of the Akagami family and now their hard work seemed to pay off because the two big bosses had decided to send the two to the Straw Hats.

The reason why they were sent to them wasn't clear but still it was played out in their favor because their goal from the beginning was to find out how many members the Straw Hats had and who they were.

The unit which did all the jobs which weren't allowed for others. The Straw Hats. The "little" group which did all the dirty jobs, which gathered information about others and supported this big families because whenever the police tried to track down the people responsible for this crime, they never could find them. The Police and everybody in the government knew that Akagami and Whitebeard where the one's behind it, that they were giving the order to the killings but they never could find the group responsible for it. They only knew that the Straw Hats had a connection to both of the, very deep one's at that.

Only three members were exposed to the eye of the public. They names were even known as well as their Codenames.

Roronoa Zoro otherwise known as Marimo, then Sanji otherwise known as Black Leg and then the leader Monkey D. Luffy known as Strawhat.

Rumors even said that the famous Devil Child and Dead Bones were in their group, but those were just rumors, it wasn't confirmed. And even though the government knew the names and codenames from three of the members they didn't know their faces. They only knew what others had told them how they looked like.

And now Ace and Law, which had the codenames Fire Fist and Surgeon of Death were finally able to meet that phantom group. They were curious to know who was in the group, how many of them there really were and which rumors about them were false and which true.

Now they just had to wait. Akagami and Whitebeard were also present with the most closest members to them, who were called commanders. Ace had formed a deep bound with some of them. The door opened and everyone fell silent. A young man with black hair and a strawhat on his head walked inside of the room and looked around. Soon after he stepped through a young stern looking man with green hair and another with blond hair which covered one half of his face walked inside and then the rest came inside.

Two girls. One with Orange hair and the other with black. Then two older looking males. One with an Afro and a scar on his forehead the other had blue hair and some of his body parts seemed to be artificial, the last one to walk inside was a teenager with brown hair and a pink hat which had a big white "X" on it, some horns were glued to it as well. And then there was another young male hiding behind the blue haired man which they hadn't noticed before. But before anybody could say or do anything the boy with the strawhat marched forward with unbelievable speed and hugged Akagami.

"Shanks!" a soft melodic voice screamed out. It was the boy who had called the name from the Yonkou. The black haired teenager laughed softly and was happy that the older male hugged him back. Ace and Law were needless to say shocked and speechless at the display of clear affection between those two.

The famous Strawhat, Monkey D. Luffy, was a mere boy!

"Heya Anchor. It has been a while~ How have you been?" Luffy immediately pouted and stared at Shanks with a slight glare.

"Now, now brat's we have other things to do then watch you two bicker." the loud voice of Edward Newgate drew the attention back to the old man. "Oh yeah! You said something about a job!" the strawhat wearing boy's voice was heard again, overjoyed.

"Yeah Anchor. We have two Newbies here and for now we can't really take care of them. That's why you and your group have to take them in for a while. They may help you with your work." Everyone of the strawhat group looked immediately at the two black haired young man. Both of them twitched slightly as they felt the skeptical and murderous gazes directed to them.

"Ace, Law. I hope you behave there." Marco spoke for the firs time as he stepped to the leader of the Straw Hats and patted his head. "Mehhh Marco, stop that! I'm not a child anymore." cam the immediate reply to that action.

"Haha I know Luffy but for the most of us you are still a brat." Luffy huffed and blushed slightly out of embarrassment. "W..-Well then we'll be going now! Ace, Law follow us." the young male quickly ran out of the room, his group following soon after with a soft and amused chuckle, followed by amused laughter of the two 'bigger' groups.

Ace and Law looked at each other and then followed after the Straw Hats. Deep down they were still shocked that the group looked like this and that their leader was this young!

When they reached a room and the Straw Hat's sat down they looked confused around. They were still in the same house, only a few rooms away from where they had stayed at!

"What is it you two?" the orange haired female asked and grinned at them. "Surprised we were this close? Oh! By the way your whole money is going to me and when you need to buy stuff you have to ask me for your monthly allowance." Law only blinked and looked at the girl while Ace looked shocked at her "What!?" "It's normal for us all." the black haired woman said and smiled softly as she picked up her book and continued to read in it. "Well it isn't that SUPER that we always have to ask Nami for the money but believe me it is better like that.." as the blue haired man said that he looked at their leader with a meaningful look, the boy turned around and beamed at them. "Ah! We didn't even introduce ourselves! Everyone!" they all sighed but a smile was present on all of their lips. "I'm Nami. The one who goes out to gather information with Robin. I manage the bills and everything else here." the girl with the orange hair said and sat down beside the other female. "My codename is Burglar Cat by the way~" she said in a singsong voice and motioned to the other female in the room.

"I'm Robin. My codename is Devil child and I'm also a fighter beside the information seeking type." she said with a soft smile and looked around.

"Hmm~ Well let's see Chopper could you introduce yourself next?" the young teen with the pink hat twitched and looked with watery eyes to Robin and then to the young black haired male which was still hiding slightly behind Luffy now. "Man up already chopper." the green haired male said and sighed softly as he saw how devastated the teen looked. Chopper took a deep breath and looked directly at Law and Ace "I..-I'm Chopper! Tony, Tony Chopper. I'm the doctor of the group and my Codename is..-" a soft blush appeared on the teens cheeks and he grumbled softly "Cotton loving reindeer." he mumbled softly. "Usopp your turn!" he then screamed as he ran to Robin to sit in her lap and hide his face in his hands out of embarrassment. He was mostly at Robin's side when he felt troubled.

"A..-A..-Alright! It's the almighty Usopp-sama's turn!" the boy behind Luffy declared but when Ace and Law looked to him he hid behind his boss again. "I..-I'm Usopp! My Codename is Sogeking and I'm the sharp shooter!" "Yeah Usopp is amazing he can hit a target which is very far away with ease!" Luffy exclaimed and grinned brightly at his friend. "Hehe~ Yup! Thanks for the cover Captain~" this confused Ace and his partner a bit, after all it wasn't very often that the groups referred to their boss by name or called them Captain.

"Well then if nobody wants to go next the it's my turn. Name's Sanji. Most of the others out there know me as Black Leg." a feral grin appeared on the blonds lips. "If you dare to hurt our Ladies in any way I will make you pay. Besides being one of the people which care for the trash I'm the cook here. Oh and that green haired moss head there is Zoro, codename Marimo." a big grin appeared on his lips at that. "I was the one who gave him that name~" Zoro glared at Sanji for a while but then turned his eyes to the newcomers. "If you dare do anything to hurt anyone in our group.. or Luffy.. I will cut you." both of them looked at each other again and nodded.

This group was really odd. But for now they had confirmed one thing. The Strawhat group existed and it had more members than they originally thought. "I'm just Dead Bones Brook and this beside me is Franky our dear Cyborg Yohohoho~ Besides us being the musician and the technic freak we also help when someone needs to be disposed of yohohoho~"

"And I'm Luffy. The captain of this Group. People called me since waay back Strawhat because I treasure and always wear it shishi~" the young boy with the scar under his eyes said happily and jumped around. "But for now..", he walked to the two undercover Agents and smiled brightly at them. "Welcome to the famiglia!"
