So I'm so damn sorry that I haven't upload in such a long time. You know? My Laptop's motherboard was broken so I needed almost 5 weeks to get a new Laptop, my finger was broken and it still is, but it doesn't hurt as much anymore. I wanted to upload by my phone but I was too lazy and I've got so much stress because of my work. But now everything is so much calmer and I try to finish ALL my stories until mid-September, because my school will start very soon and I won't have time for my stories at all. But oh well, enjoy this story

No one's POV

The rest of the evening, Mona and April were chatting and telling each other what has happened in the last weeks. "And there was this guy, his name's Casey Jones. He once tried to save me from the Turtles because he thought that they wanted to harm me." She told her and giggled slightly.

"GUYSSS YOU DON'T KNOW WHO I'VE MET ON MY WAY HERE!" screamed an unfamiliar voice, well unfamiliar for Mona. "Speaking of the devil." Muttered Donatello under his breath.

"There was this squirrel monster again. I've hit it between the legs and it melted away." He said in over excitement and made a :O face.

"That's awesome Casey!" Said April and smiled in amusement, while Donnie glared at his newly human best friend. Of course, Monalisa caught him and smirked, knowing what's going on. "Hey Donnie, would you show me your lab?" she asked him and got up.

The turtle with the purple bandana blushed and scratched himself behind the back. "O-of course Mona. Just follow me." He said and showed Mona the way to his lab.

"See you later April, alright?" she shouted at her best friend while walking behind Donatello. "Of course, have fun!" the redhead answered.

"Wait Donatello and Monalisa!" The two mutants stopped walking and turned around. Master Splinter suddenly appeared behind them. "Donatello, make sure you bring Monalisa into my mediation room, I need to talk with her." He said and the lizard girl and turtle boy nodded and went to Donnie's lab.

"Well, here you are. My lab." He said and Mona made huge eyes.

There were tons of mutagen on a huge shelf, a blob-like mutant swimming in a glass box. Mona turned around and saw scalpels, test tubes and anything else what you can imagine in a lab. "Wow this is so amazing! Why did you deposit the mutagen in your lab?" She asked, full of excitement.

"Because he's scared that another accident happens." Said someone, the voice coming from the door. Mona turned around and saw Raphael leaning on the doorframe. "Another accident?" She asked.

"Yeah, a lot of things happened. See, we're not the only mutants. There are a lot of other mutants out there, that we try to fight and when I find a cure for the mutagen, we'll try to transform them back to normal. Especially our friend Timothy over there." He said and pointed to the blob.

Mona looked at Donnie and then at Raph. She had a sad facial expression. "Donnie, if you ever need help to find a cure, let me help you." She offered him her help and put one of her webbed hands on Donnies shoulder. The turtle smiled. "Thanks Mona. I appreciate it. But let's go to Splinter." He said.

"I'll show her. You can go back to your mutagen work." Raphael grunted. Mona scrunched her face.

"Hurry lizard." He said and walked away from the door.

"Lizard?! It's Mona! You dimwit!" She yelled but still followed him. "See you later Donnie!" She turned around and waved at him before running out the door.

"I'm still waiting lizard. If you don't hurry, I'll pull your tail and drag you along." Raph interrupted her, which made Mona almost explode. "What's your fucking problem Raphael?!" Said the mutated human in an angered voice.

"Nothing, just keep going lady." He muttered under his breath and lead Mona the way to Splinter.

~Meanwhile with Splinter~

"Sensei? Do you think it's a good idea? I mean, we barely know her." Started Leo on his Master.

"Oh come on Leo, she's my best friend and she really needs help from you all." The redhead tried to convince the turtle but he didn't give in.

"Why-" he tried to ask something but got interrupted.

Mona and Raph got into the room. "Ah, Monalisa and Raphael. Just the two I wanted to see, especially you Mona." The Sensei welcomed the two mutants with a huge smile.

"You wanted to speak with me Sir?" the mutant lizard asked. Splinter nod his head and gave her the "sit-down" gesture and she sat down. April sat down next to her best friend and looked at Splinter. The sensei joined them and got serious.

"Mona, the way how the Kraang have attacked you wasn't good. They know what mutants are capable of, since we all aren't the only mutants here. They have seen a lot of enemies who once were human and sadly they are all on the bad side. (*)" He started.

April showed off her usual grin to Mona, knowing what will happen soon.

"And now, I want to offer you my help to train you to be a Kuno-Ichi. A female Ninja. April will be your training partner." He said and Mona just had a shocked face expression.

"You want to train me? Why?" Mona asked.

"So you can protect yourself from people who try to catch or hurt you."

"Oh my gosh, this would be so amazing! When shall we start?" Mona almost yelled.

"We shall start tomorrow, but today, April will show you the basics and I want you to practice until perfection." Demanded Splinter. April put her hands to the side and bowed, Mona copied her.

"So Mona, let me show you." April started and soon they started with training the basic moves.

~Skipping to some hours~

April walked out from the training room, panting heavily while Mona was breathing really normal.

"Wohoo looks like you didn't do anything Lizard Lady" said Mikey and laughed his Shell off. He was rolling on the ground from all this laughter.

Mona raised her left eyebrow. "No Mikey, her stamina is really really high, probably higher than yours!" April panted and wished off the sweat forming on her forehead.

Now it was Mona's turn to smirk at the turtle with the orange bandana.

"No way, it ain't possible! I want a race!" yelled Mikey in shock.

"You really are over reacting Dude, but alright. Let's do this!" said Mona. "And I'll race you all." She added and smirked as she saw the faces from the others in the room.

I hope you've enjoyed this, stay tuned for the next chapter.
