Donatello stepped out of his 'prison', looking for where his former capturer had gone. He told him to just leave, but being out in a hallway he saw that it was still bright day outside. Plus he couldn't leave his friend's son alone like this.

He continued his search, taking in the surroundings. It looked like an abandoned office building, having many small rooms with no furniture except some left working tables and broken monitors. One of the doors was not wide open, but left ajar. He was just about to call out for 'Murakami-san Junior', as he was calling him in his head since he had no name yet, when he heard his quiet voice accompanied by sobs.

Who was he talking to?

Cautiously the turtle neared the doorway. There he saw him through the small gap, kneeling and arms stretched forward for some reason.

"F-forgive me, father. I made a mistake - I dishonored you by hurting your friends, I-I... would've killed him..."

The brainiac tensed in an instant when he saw steel flashing. "NO!"

He threw himself into the room and crashed onto the human, grabbing the hands holding a katana which then landed on the floor with a loud clattering sound.

"WHAT THE SHELL WERE YOU THINKING!?", the turtle screamed as he knelt above the person who just tried to commit hara-kiri - suicide for regaining honor to the family after crushing it - and grabbed him by his collar. He hadn't even imagined there were still such traditions nowadays, especially from someone of Mr. Murakami's family.

Big, tear-filled eyes stared up to him, trying to understand what just happened. "Why...?" He tried to struggle himself out of Donatello's grip which only resumed in him failing and crying out loud, ripping the mask off his face screeching: "WHY DID YOU STOP ME?!"

The normal answer to such a question would have been to babble something about not throwing someone's life away and such, but the turtle went silent, staring into the now revealed and tear-drenched face.

The voice had been muffled by the mask and the cloth were thick and wide so he couldn't make it out earlier, but-... "You- You're a girl?", he finally managed to bring out in disbelief.

She didn't respond to that since it was quite obvious now and stopped trying to free herself; instead she gave in and cried out loud, failing to hold back any longer.

Donatello continued to stare at her, not knowing what to do, so he released his grip and she could at least sit up.

"S-sorry...I'm so- sorry...", she blabbered quietly while still sobbing, "I didn't wa-want to-..." His arm found it's way around her shoulders, being the only thing he could think of to comfort her. "Shhh, it's okay. I still got my head, see?"

He tried to smile reassuringly as he pointed to his throat. The girl grabbed him tightly by the belt holding his staff and now cried even louder into his shoulder, releasing all the pain and sorrow about her father's death she had held up until now by clinging to the thought of revenge.

It was soon going to dawn and the Team including April was sitting in the severs, itching to go upside. The air couldn't be more charged as everyone's nerves were on edge.

The shrill sound of Leonardo's T-Phone suddenly cut the silence and made everybody jump.

"It's- it's Donnie!", he exclaimed, staring at the display wide-eyed before picking up. The others were at his side in no time, trying to catch something from the coming conversation.

"Guys, it's m- " "DONNIEOHMYGODYOU'REALIVEWHEREAREYOU?!", Mikey shrieked straight into everyone's ears so loud even Donatello on the other side nearly had a heart attack.

"Guys, guys! I'm alright, I'm alive, I'm not hurt, okay? Don't panic and stay at the lair, I'll come home as soon as sun sets and explain everything to you. See ya then!"

And with that he hung up, leaving his family even more confused as they were before.

Donnie kept his promise: It wasn't long after dark that they heard someone coming. His brothers nearly tackled him into the water canal as they rushed and crashed into him, hugging him to death. "DONNIEWEMISSEDYOUSOMUCHBRO!" Of course, Mikey was the loudest of them all.

"Guys- air-!", was the only thing their brother could manage before they released him. "Geez, you crushed me, guys!" Despite him gasping for air, Donnie laughed. Hours ago he didn't think he would ever see his brothers again and now he was here.

"What happened?"

Raph was the one to finally ask the question everyone had on their mind. Sighing, the brainiac went to the couch and sat down.

Donnie told them the whole story about Murakami's death, the T-phone which was planted as false evidence and the kidnapping. He left out getting beaten up and the hara-kiri attempt, but still it took some time to explain everything that happened.

Silence followed. The air was heavy with grief over their friend's death; April was crying over his shoulder. Leo was the first one to break the silence: "So... he actually had a daughter?" The purple masked turtle nodded. "Seems so. And she was led to believe we were the murderers up until now."

April lifted her head, looking at him with tear-filled eyes. "Poor thing. Where is she now?", she asked between sobs. "I don't know, she kind of vanished before we could talk. She should've been living with her father, I guess, but I don't think she wants to return there. Judging from her fighting skills, she'll manage somehow."

Days passed and the turtles managed to return to their daily routines. Though they still mourned Murakami's death, they focused on finding out what had happened. Since the murderer wanted his daughter to annihilate them, thinking they did it, it must have been one of their enemies.

But who? The Kraang, the Shredder, some random villains they pissed of somehow... there were many possibilities. They didn't even remember where they had lost one of their T-phones, but judging how Mikey always let them lie around it could have been anywhere.

Donatello sat in his lab, thinking hard. It must have been someone who knew Mr. Murakami had a daughter, and who also knew she was a high-skilled Kunoichi. But without having any more information about her it was impossible to track down such a person. He already tried tracking the broken T-phone, hoping she still had it in her possession, but the signal was dead. He didn't even have her name...

He was thrown out of his thinking when his T-phone went off. "A message...?" He snatched the phone and looked who it was from. Unknown number...?

Come behind the 24/7 after sundown.
It's important.

"And it's a trap, I tell ya!"

Donatello had informed his brothers as soon as he read the message. The reactions were mixed; Mikey had fantasies about some awesome adventure coming, Raph thought it was obviously a trap. Leonardo hadn't said anything yet, he seemed deep in thought.

"I'm gonna go, whether you're with me or not, Raph", Donnie stated with a stubborn expression on his face, "I need to know where this person got my number. Maybe someone's watching us? In this case we can confront him right then."

Their leader looked at him. "I think Donnie's right. And since the message was send only to him he - or they - won't expect all four of us coming."

Raphael growled, folding his arms. "Fine. I'll go with ya. But don't come cryin' when some creeper kicks your butt!" Mikey jumped up and began running around the living room in excitement. "Hooray! Super-secret-awesome-kickass-adventure here we come!"

At sundown they made their way to the surface. They carefully opened the lid to the manhole they were rising from. Who knows, if the person had Donnie's number he could be following them right now, too.

When no one was around, they jumped out and continued along the roofs to the 24/7. Everyone was quiet except for Mikey, who couldn't stop babbling about what was to come. "Maybe it's an agent who wants us to save the world from some super secret space invasion! Or it's ourselves from the future who need our help, or-!"

"MIKEY, would you stop that?!", Donnie snapped, obviously tensed.

"Orrr...!" Suddenly his little brother grinned from ear to ear, facing him. "...Orrr our dearest Donnie has some secret admireer!"

That earned him a smack on the back of his head, not only from Donatello, whose face turned a dark shade of red, but also from the other two.

"Quit fooling around, we're almost there!", Leo hissed and shot them a serious gaze. "Donnie, you go down and wait for whoever it is. We're staying up here so they don't know you're not alone. Guys: Stealth mode!"

And with that the three of them disappeared in the shadows, leaving their brother to wait in the small alley behind the 24/7 alone.

He didn't have to wait for long; after a few minutes something rustled behind one of the trash containers and a figure appeared out of the shadows. He couldn't make out any facial features since the shadow of it's hood covered everything.

"You came", it simply said, a glimpse of surprise in it's voice. The turtle blinked. "Uh...yes, you told me to. Who are you, anyways?" The figure took some steps further to him and lifted it's arms to-

SLAM!

Before it had time to react a red masked turtle came down from above and tackled it to the ground. "DON'T YOU DARE LAY A FINGER ON HIM!", Raphael shouted, pinning the figure down.

"Raph, what the hell!", Donnie screamed, not understanding what made him tick out.

"Sorry, we couldn't hold him back!" The other two landed beside him, apologetic looks on their faces.
"What do you want with my brother?!" A sai was pressed to the figure's throat. It gasped, pressing it's head to the ground, trying to escape the metal.

"I-... I need his help!", it suddenly yelled.

Raph blinked, though not lifting the sai. "Who the hell are you?!" He tore the hood off in one quick motion as his eyes widened.

"Raph, let her be, it's Mr. Murakami's daughter!" Donatello grabbed his shoulders and pulled him off the girl. She jumped up in an instant, rubbing her throat. "Geez, nice to meet you too, tough guy. The name's Kimiko by the way, Kim for short."

Raph was let go of his brother's grasp, but Kim didn't fail to notice he still had his weapons out. Such an untrusting fellow... she grinned.

Leonardo and Mikey stepped forward, eyeing her curiously. "I'm Leo, that's my brothers, Mikey and Raph. You already know Donnie, I guess", he introduced themselves, not really sure how to deal with the girl yet. His little brother didn't stop at this, but circled around her with only few inches between them. As usual, he didn't know of anything called personal space.

She stood perfectly still, but her eyes followed his every movement. "Dude, you look like shit", he suddenly stated, earning shocked looks from his brothers. "MIKEY, that's not how you talk to a-" "Donnie, he's right."

Leo had held him back from jumping at their youngest. At a second look it was clear to see the girl was really worn out with dark bags under her eyes and her clothes pretty run-down.

Donatello gaped at her when he saw it, too.

"...Kim, what's going on?"

She lowered her gaze to the ground. "As I said, I... need your help. The Foot Clan is kind of after me. I've been roaming the streets for the past days to avoid them."

Everyone stared at her, waiting for further explanation. Looking at their expecting faces, she continued: "They know where I live, that's why I need somewhere to hide. Since I've never seen some giant green turtles ninja-ing around here at night I thought you guys were pretty good at it." Eyeing every one of them she waited for some kind of answer.

"So that's why you texted me. Where did you even get my number, anyway?", Donnie finally asked, that being the primary reason he wanted to come to this meeting.

A crooked grin appeared on her face at this. "I still have your phone. It was broken, but I managed to extract the contact data from it's memory."

Raph snorted. "Great, another nerd."

His brothers ignored him; their leader was busy holding the brainiac's mouth shut with his hand, knowing very well the spark in his eyes that could only mean his scientist-mode switched on. But now was not the time nor place for this stuff.

"So-", he spoke, having a hard time holding his brother still, "so you thought we could help you hide how exactly...?"

Kim looked him straight in the face. "Take me with you. I still need to find my father's murderer, but I have my theory. Since you were his friends I guessed you would be interested."

The turtles thought for a moment. Or rather they wanted to, but Mikey already jumped at the girl, hugging her tightly. "Yay, I knew it! We'll be the coolest detectives, like, 'Turtles and their Roomie!', that'll be so aaawesome!", he exclaimed.

"Not so fast, dumphead!" Raphael pulled him away from her, smacking his forehead. "You want to take some stranger to ours, what're you thinking?!"

His brother pouted in response. "But she's Mr. Murakami's daughter and needs our help, you heard it?" That earned him another snort from his elder. "For all we know she could be lying! Who says he even had a daughter? Who says she isn't part of the Foot?!"

"Raph, enough!", Donnie yelled. He had freed himself from Leo as this topic was of much more importance now. "I know she isn't lying, isn't that enough to trust her?" He still remembered her crying over her father's death. That wasn't a lie.

Raph shot him an annoyed glance. "Yeah, like you are the one to judge that! You see a cute girl and that's it, you lose your head!"

His brother didn't have an answer for that, but just gaped at him open-mouthed.

Just when Kim was about to counter that, multiple shadows dropped down around them.

"Oh, I knew it! It was a trap!"

In a matter of seconds they were surrounded by Foot ninjas. Kim went pale. "Guys, I swear, they're not with me!"

And then hell broke loose.

The Foots launched at the turtles and vice versa. The girl still stood in shock until her reflexes kicked in when Raphael charged at her with his sai. "Raph, stop! They're my enemies, too!", she shrieked as she blocked his attacks with her Kama. But he didn't hear. "As if! How dare you-"

He was interrupted when one of the Foot bots struck her side with full force, smashing her into the wall, and gasped.

Whoops.

"See? You stupid-..." She coughed from the blow and stood up, holding her side. There was no time responding as more of the Foots came. One of her Kamas found it's way in the head of her attacker who dropped instantly, sparks emerging from the gap. She huffed and scowled at Raphael, who now pierced one of the bots after another with his blades. At least they fought on the same side now.

The alley rang with sounds of clashing steel and dropping bodies and for a while it seemed as for every Foot they disposed of others came. But after a while they were finally fewer and Kimiko was in good spirits they would make it out of here soon; until a voice appeared right behind her:

"Long time no see, we were looking for you."

Her face went deadly pale as she slowly turned around and froze.

Samuel.

Of all the people, him.

There he stood in his Foot cloth. He hadn't changed at all since the last time she saw him, except for the way he looked at her.

He was smirking, but his eyes were hard and cold.

The fighting sound around her ceased as now there was only him she focused on.

"You're teaming up with those freaks now, babe? What a shame", he stated and motioned to the fighting turtles.

"Don't you dare call me that, Samuel", she spat, readying her Kama. "You planted that phone, didn't you?"

He laughed. "What other way to let you finish them off, honey? They're our enemies, after all."

Kim snorted at that. "Your enemies maybe. They didn't kill my father for sure."

After a moment of hesitation she whispered: "...did you?"

Silence followed as he pursed his lips and pretended to think about it. That was when she knew the answer and her vision went blank.

"YOU FUCKING TWAT!", she screeched as she lunged at him. "HOW DARE YOU!"

He blocked every one of their attacks, still laughing. "You ain't got more than that?!"

She was sending one blow after another at him, to no use. But there was no retreat for her, no mercy. All she had on her mind was rip this fucker apart for good. She didn't even notice the Foot bots were already finished off and the turtles staring at her in shock at her fury.

Punch him!

Again her Blades were blocked by his.

Kick him!

He got to grab her leg and throw her in a wall, but she jumped up and was on him again in an instant.

Stab him!

One of his swords managed to cut her arm, but she didn't care.

Kill him!

She threw her Kama at him and sheathed a dagger instead. While he was smacking her weapon away she got an opening and charged. Blood splattered as she managed to cut his face, but sadly not deep enough.

He growled. "You're gonna pay, bitch." No smirk, no laughter.. His face got dead serious as he launched, not playing around anymore.

The turtles still watched, but no one wanted to step in yet. This seemed like a fight she alone wanted to run.

More blows came, and more blood.

Until the girl suddenly froze mid-strike and fell on her knees. Her eyes widened. "What-...?"

Samuel lowered his blades and his smirk returned. She stared at him in disbelief. "You didn't...?" She coughed up blood as she dropped further, her muscles slowly going limp.

"Don't recognize your own little trick, Kimmie? You were the one who taught me to use that poison, after all." He chuckled and took a step in her direction, lifting his sword in a ceremonial matter.

"Now let's finish this pity life of yours like I did with your father."

That was when the turtles finally took action, seeing there was no way she could survive on her own now. Leo blocked his strike with his katana while Raph and Donnie grabbed the girl, and Mikey-

"Booyakashaa, sucker!", he yelled and dropped a smoke bomb.

The alley was filled with thick purple smoke, making Samuel cough and lose his vision. And when it faded, everyone had vanished.

"Tch. Next time, bitch. That's a promise", he spat and turned away, leaving only masses of demolished Foot robots behind.
