Hello and welcome to my new project the TMNT (Human AU story) called Teenage Ninjas. I know it's been done quite a few times but I always wanted to do my own take. This story will be updated every weekend with one or sometimes two chapters, due to school and work It'll be more difficult to do so during working days. This weekend we open it with three chapters which will set the background for this story. Do not hesitate to give your opinion please but if you only want to insult I suggest you keep it to yourself. Without more delays I present you my story of Teenage Ninjas (Season 1)

AN: I do not own TMNT, if I did I wouldn't be writing this as a fanfiction. All the credit goes to the creators.

Teenage Ninjas Season 1

Episode 0.1

Hamato Yoshi arrives in NY.

A japanese man, black haired, tall of slightly strong complexion and dressed in Traditional Japanese clothes, walked through the John Fitzgerald Kennedy Airport after getting off a plane that had just arrived from Tokyo with a sad expression filled with regret, it was no wonder though he'd lost everything cared about. Yes, Hamato Yoshi was a man that had lost it all, he'd lost his wife and daughter, both killed or at least he knew his wife was, he only supposed their baby had shared her same fate, by a man who had grown up with him and had been his brother in all but in blood, Oroku Saki. The same man who after being raised by the Hamato clan had brought them down and rebuilt their bitter enemy clan, the Foot Clan. Yoshi growled as he thought of this but pushed such thoughts aside, revenge was only for the weak and he was not weak, he would eventually rebuild his clan and then he would return to Japan to defeat the Foot Clan once and for all, not because he wanted revenge but because his "Brother" had to be stopped.

Hamato continued towards the exit as many passengers from his flight went to pick up their luggage, he did have too little to carry with him, just a photo of him with his daughter and wife, so he was spared that tramit. Exiting the luggage zone he looked around when he exited through the Arrival's gate

"He said he would be here." He muttered to himself as he scanned the crowd families, friends, travel agents and drivers awaited at the arrivals zone of the terminal for the next group of passengers. Finally after a few seconds of looking through the crowd a second time he spotted the person he was looking for. A blond haired man dressed in a bussinessman suit but with the demeanor of a child as he waved for his friend with a wide ignorant smile, he didn't know what had happened and Hamato made his resolve to keep it that way so as to not endanger him or his family. When he reached the man he offered him his hand which the man rejected going for a hug instead.

"It's good seeing you Yoshi." The man said as they pulled away.

"You too Frank." Hamato replied offering him a weak and unconvincing smile. The man named Frank eyed Hamato suspecting something to be off

Frank Miller was an old friend of Hamato Yoshiand the son of a long time embassador of the US to Japan. He had become friends with Tang Shen, Oroku Saki and Yoshi during their highschool days and at least with Yoshi and Tang he'd kept a close relationship via email when his family returned to the States. He'd been delighted when Yoshi told him of his plans to visit the States under the pretext of opening a Hamato Dojo in an American city with the posibility of opening branches in several cities if the first one was successful, he'd insisted that New York was to be his first stop and he absolutely had to stay with him and his wife while he was there and the japanese man was sure that he would also try to convince him to set up his dojo in NY. For all those reasons it'd been very hard to tell him that Tang could not come yet because she was caring for little Miwa, he hated lying to such a kind man although the painful memories such a lie brought, the image of his beautiful wife caring for their daughter back home, were also a reason.

"So tell me how was the flight?" Frank asked his friend as they walked through the terminal towards the parking lots.

"As horrible as the first time I came to the States." Yoshi attempted to joke.

"Yes I remember it was the time you and Tang came to my wedding to Amanda isn't it?" Frank said reminiscing of the time he'd invited Tang and Yoshi to his wedding, he'd invited Saki, Yoshi's adoptive brother, too but the man had politely declinely alledging having to work on the Dojo with the master. Yoshi had gotten sick on the way to the US and had been in a bad mood for a whole day before Tang had finally told him that he couldn't be that way, that he had to be happy for his friend Frank and his wife Amanda, a beautiful italo-american woman, with blonde hair, olive eyes, tanned skin and beautiful facial features and a petite complexion, who at first sight seemed a little naive and frail but whose personality was that of a self-dependent strong woman who'd taken good notes on all the lessons her life had given her.

"Yes it is. Yet seeing you again is as good as it was that time." Yoshi replied.

"Thanks Yoshi." Frank replied. Walking a few minutes after exiting the airport they reached his friend's car parked on one of the airport's parking lots. It was a volkswaggen family van somethig too large for just a married couple. He stopped at his friend opened the car observing curiously after remembering Mike's wife had been pregnant, in fact she had just broken the news to Mike when Yoshi last spoke with his old friend, and it had indeed been too long.

"So I assume the little one is already here?" Yoshi asked as he got into the car the little one.

"Little one?" Frank asked in confusion before he realized what his friend was talking about. "Oh yes they were born quite fine and all of them are a month old."

"All of them?" Yoshi asked, this time it was his turn to be confused by his friend's words.

"I suppose I didn't tell you did I?" Frank asked with a wide smile. "I've had more than one child"

"More? Then... twins?" Yoshi asked becoming curious.

"Nope." Frank said taking the car out of the parking spot and beginning the ride back home.

"So how many?" Yoshi asked.

"Mmmh... I don't think I ever surprised you did I? Let this be the first time then." Frank said his smile turning mischievous. Instead of replyingYoshi just narrowed his eyes at his friend. "You'll just have to wait and see Yoshi" Frank added. "There's a first time for everything after all."

((((((((((((((((((((((((((((((((((((((((((((((((Teenage Ninjas)))))))))))))))))))))))))))))))))))))))))))))))))))))

Yoshi observed the four sleeping babies, all of whom where identical between them with a few black hairs and yet undetermined eyes, on their cribs under the watchful eye of their proud parents who were both smiling at their friend. Due to a terrible traffic jam Frank and Yoshi had arrived to Frank's home, a little apartment located near central park, a little after dinner and after Amanda had put the babies to sleep. Upon learning this Frank had barely allowed his friends to greet his wife and had lead him towards the baby room where the four babies slept. "How is it? Not a bad number for the first time trying to be parents huh?" Frank had told him as he introduced him to the babies and smiled knowing he had indeed surprised his friend, but aside from his surprise Yoshi could not help but feel a pang of sadness as he observed them thinking of his own child Miwa, who'd had such a short life, he thought of all the things she would never be able to do and all the things he wouldn't be able to share with her and began to feel hate for his former brother again, he breathed profoundly and sighed trying to keep all those thoughts out of his mind.

"What are their names?" Yoshi asked bringing his mind back to the present.

"The older one is Leo" Amanda introduced the first baby who slept on the crib on the upper left corner of the room. Pointing to the other upper corner she said. "Raphael." Then she pointed to the lower left corner "Donnatello" and finally she pointed to the final crib. "And Michelangelo"

"Like the renaissance italian artists?" Yoshi asked looking at Amanda who smiled.

"Very good, that's right." Amanda said with a warm smile as all the adults exited the room and went to the living room.

"I suppose I have to congratulate you both, your children are beautiful." Hamato said with a smile.

"I'm sure Miwa is equally beautiful" Frank replied as they all sat in the couches at the living room. At that moment Yoshi sighed and Hank eyed his friend wearily, knowing his friend had something he wanted to tell him but couldn't bring himself to. "Honey would you mind preparing something for dinner? I'm starving and I'm sure our guest is too." Amanda nodded getting the message and heading for the Kitchen. Once alone Frank gave his friend a stern look. "Ok Yoshi what are you not telling me?"

Yoshi looked at his friend and knew that lies wouldn't cut it anymore. He hadn't done a good job at keeping the façade of normalcy either not that he could have given the situation. "Miwa and Tang Shen are dead Frank." He confessed, Frank's eyes went wide at this revelation.

"What? How?" Frank asked unable to believe Yoshi's words even if his friend's face told him it was the truth.

"Saki did it." Yoshi explained.

"Saki?" Frank asked even more surprised. "But he was like your brother! You guys were raised together as such!"

"He was but he was jealous, he always was of what Tang and I had. He tried many times to get her to leave me and go to him but Tang Shen loved me, she was faithful." Yoshi explained with sadness in his eyes trying to suppress the tears that threatened to fall.

"But killing your wife and child that's a bit extreme. I know Saki has always had a rivalry with you but that's..." Frank said.

"He discovered my true story that he was really a member of the Foot clan, rescued and raised by my father when the Hamato clan apparently defeated them." Yoshi clarified. "That was the last straw, he did not only end my clan with a group of traitorous ninja but he killed my family along with the ninja that remained loyal to my clan and he burnt the family dojo."

Frank let Yoshi's words sink in. While Saki had also been a friend of his he'd always known he was a little different from Yoshi much more ambitious and even ruthless but he didn't expect this from a man he had once called friend. He looked at the man before him.

"What is your true reason from coming to the US?" Frank asked.

"I did come to flee him and his Foot Clan but not only that. It is my intention to train until the day that I finally have to face Saki once more." Yoshi said.

"I see" Frank said getting a clearer picture now. "Why did you lie to us though?"

"I needed to get out of Japan and I was afraid you wouldn't believe me if I told you what happened, besides I also wanted to protect you. It's my intention to leave you and your family alone as soon as tomorrow I can't put you at risk any further."

"That's absolutely intolerable" Frank said in anger.

"I understand that you don't want to put your family in danger any longer for my sake but I told you I will only need one night of rest to be on my way."

"It's absolutely intolerable to think that I will let you leave and not help you when you are in danger" Frank said with a determined voice. "You will stay here for as long as you need."

"Frank be reasonable, think of Amanda and the children" Yoshi pleaded with him.

"I am being reasonable. I do think of them Yoshi and I think this arrangement will be better for everyone." Frank said as Amanda brought them some meatpie leftovers from lunch. "You will stay here and we'll help you find someplace safe and you in turn will protect my family. We'll keep each other safe."

"Frank it's too dange..." Yoshi began to argue again but Amanda stopped.

"It's useless to argue with Frank when he gets like this Yoshi, the best you can do it's to accept." Amanda told him with a soft smile making Yoshi realize she had heard the entire conversation.

"I don't understand. I lied to you both" Yoshi argued.

"If I was in your situation, I do not know what I would have done." Frank told him. "You couldn't have been thinking straight at that moment but it doesn't matter because all has turned out for the best."

Yoshi sighed and nodded grateful for his friend's kindness and promising to himself he would wouldn't let anything bad happen to them or their children. Little did he know he would only be able to keep the promise partially.
