On a cold night, all was silent in New York as usual.

In the sewers, two terrified siblings were wandering, trying to find their daddy and brothers, when the youngest of the two smelt food and pulled away from her brother, who instantly darted after her.

"Y/N! Y/N!" He called after the female but when she didn't stop, sighed and ran after her. Eventually, he found her at a ladder, her E/C eyes glimmering in hunger as she faced him.

"Y/N, daddy said never to leave the sewers" the boy reminded Y/N, who responded "Can't ya smell that, 'Ikey? If we are careful we can get some, stay hidden an' then find daddy" she pleaded, her E/C eyes locking with the baby blue ones of the boy, Mikey.

Mikey went to say no, but paused as his stomach rumbled as well. Giving in, he nodded but just as quickly said "As soon as we have food, we are back here, got it, little sister?" He demanded seriously, as their daddy had always made sure that he knew he had to protect her, always.

She nodded and smiled happily, as she began to climb, both unaware that in another world, they wouldn't have gotten lost and stayed with their siblings, and they were both unaware that above, a Asian man and his daughter were just leaving a Japanese restaurant and as such, saw them as they left the sewers and just as quickly ran into the shadows, disappearing so easily that if the pair hadn't seen them, they wouldn't have been aware they were ever there.

Mikey stared at Y/N, scared. "Now what? What do we do now, little sis?" He asked anxiously, as he really wanted to get back inside the sewers and home to daddy, before they were taken by the men that would lock them away and treat them badly just because they were mutants.

Oroku Saki had planned for a simple night with Karai, his daughter and he had certainly not planned to come across two turtle like creatures, appearing to be children but looks can be deceiving, climbing from the sewers.

Before he went to go investigate them, he took Karai to the car and after giving her to a bodyguard who would look after her or if not the bodyguard would pay for it with his life, and then approached the alley that he had seen the two Kame children go into.

Mikey froze as he heard footsteps before he tapped Y/N and pointed to the ladder. She nodded before beginning to scale it, Mikey quickly following her and both disappeared just as Saki appeared but all he saw was an empty alley.

"Kame?" he called out and Mikey replied "Go away!" defiantly causing Saki to smirk in triumph at hearing the childish voice. He had been correct in assuming that they were children. But only one replied, meaning the one that spoke was the protector of the pair, or the other Kame that had been with him, he thought it was a him as the childish voice sounded male, the other Kame could have disappeared, which he thought highly unlikely.

"Won't you come down?" Saki continued, "I bet you are hungry aren't you?" He asked them and Mikey opened his mouth to say no when Y/N answered "Yeah!" And immediately after Saki heard a face palm after the clearly female childish voice had answered, most likely coming from the male.

"Well, if you come with me, I could give you food AND a bed. I also have a daughter, Karai that will be thrilled to meet you as she loves Kame like you" he continued.

Mikey stopped as he considered it, before looking up at Y/N, the only part of her visible was her eyes, which looked pleading and hungry. He then remembered why exactly they disobeyed daddy and came up here in the first place.

He stares up at Saki, saying "I need to discuss it with my sister" and Saki nods, backing away to give them the privacy they need.

Mikey looked down at his younger sister as he asked "Should we? I mean, it is unlikely anything good can come from it" and Y/N responded "Yeah! We haven't eaten in days 'Ikey because Leo, Don and Raphe keep taking our foods an' I'm hungry!" she whined up to him.

After she said that, Mikey stopped and thought. It was true that Leo, Don and Raphie were taking their foods but by going with the man, what's to say he won't hurt them even if he does offer food.

He nodded and turned around, the smaller turtle climbing on his back as she grew more tired and after wrapping her arms around his shell, she drifted off.

Mikey approached the man slowly. Saki turned around at the sound of footsteps to see one of the Kame approaching him, while the younger Kame slept on the older one's shell in her sleep.

Mikey stared up at the man and told him boldly "Me and my sister accept your offer. But-but if you try any funny stuff, I-I'll kick your butt!" he blurted out bravely, and Saki looked taken aback for a minute before he chuckled slightly.

"If you say so, young brave Kame" he humoured the boy "Come, I have left Karai long enough" he turned and walked off, Mikey following him as he gripped onto Y/N so she didn't fall off in her sleep.

Finally they arrived back at the car, where Karai sat up as she saw Saki, about to speak before her eyes landed on the two Kame. More specifically, her eyes landed on the cute sight of the younger Kame clinging to the older one.

She hopped out of the vehicle and ran up to them, introducing herself excitedly "My name is Oroku Karai! What are your names?" She questioned and Mikey answered "My name is Michelangelo, Mikey for short, and this" he said, gesturing to Y/N " is my little sister Y/N."

Mikey gently prided the girl off his back and transferred her to his arms instead as he got into the car, Karai getting in after him while Saki headed around to the drivers side and together they drove off.

Meanwhile, their father was with their other three siblings worrying over the fate of his two youngest as he couldn't find them. He didn't realise that he wouldn't see them for many years, but as the years went by, they faded from the memories of his three oldest, and as such, they believed that it had only ever been three turtles, not five.

Mikey and Y/N had also forgotten about the ones that they had left behind as well, and started to believe that they had always lived with Saki, him being their father and Karai being their older sister.

This was fine with Saki, he had two Kame he could train into a ninja and kunoichi respectively, not to mention his own daughter Karai, who just adored the fact that she had little siblings to look after and she took her duty seriously, never allowing any harm to come to them and the one of the things that she and Mikey agreed on, was that no harm would come to Y/N, the baby of their family.
