Hey! This isn't Harvest Moon! Yes I know. Sorry for the delay, but I'm having a bit of trouble writing the next chapter. This fanfic though has been sitting around in my computer for awhile. I've had this idea for a long time and wanted to write it down.

It's about the teenage mutant ninja turtles and my OC. She gets mixed up into their lives and, as they learn more about her, causes tons of trouble. More so for Leo than the others... ;). This does have romance, but really, not a lot of it until later on. The story is supposed to work with the 2012 ninja turtle show by the way.

However, until further notice, this story is only going to be updated when I have time. If you guys like it more than the other then tell me and I'll try to update more often. Anyway, on with the story.

Being a teenage mutant ninja turtle is not that normal. Leonardo, Raphael, Donatello, and Michelangelo know that first hand. But when they meet a girl the same age as them, completely human and what appears to be completely normal, why does her life suddenly tangle with theirs? Perhaps there's more to her than meets the eye. Maybe we should look into the first time the turtles met the girl.

It started with the new assignment Master Splinter had given the boys. An unfamiliar enemy had recently shown his face in New York City. He was called the Reaper and the team found him dealing with the Kraang, his goal being the mutagen the Kraang had made. No one knew for sure how he got the aliens to make a deal with him, but Splinter assured them that the Reaper was not a friend. The turtles' mission was to find the Reaper's hideout, discover what he means to do with the mutagen, and stop the plan at all cost.

Donnie easily found where the Reaper was hiding, concluding that he didn't even try to conceal his face when he walked around town. By that night, the boys were racing across buildings to reach the car garage the Reaper called home.

"Hurry up you guys or I'll have beaten every last bad guy before you even get there," Leo taunted.

"Oh, not happening Leo!" Raph shouted, speeding up slightly to catch up with his older brother.

Mikey laughed at himself. Raph, Donnie, and he were behind Leo because Mikey had tried to do a cool flip over a building, only to have a misstep and trip his two brothers.

"What do you think this Reaper guy is like? I've never heard of him until now," Donnie wondered.

"I don't know, but I bet he's fun to punch!" Raph chimed.

Leo suddenly stopped. "We're here."

All four brothers leapt off the building. Just up ahead stood the rather large car garage the Reaper was supposedly taking refuge in. Leo took a look at the shop and then pushed his brothers into the nearest alley.

"Hey!" Raphael protested. "What are you doing? The fight's that way."

"Ssh, Raph; I thought I saw someone coming down the street," Leo explained. He leaned against the side of the alley and peeked around the corner. "I don't see them anymore, but we should stay put to make sure."

Michelangelo pushed his way in front of Leonardo. "Relax bro. It's the middle of the night during winter. Who's gonna see us?"

To prove his point, Mikey jumped back on the sidewalk and extended his arms like he was about to hug someone. Then, just as Leo was about to call Mikey back, a teenage girl ran right into Mikey's right arm.

"Aaah!" she screamed as she fell and tumbled to the ground. It appeared like the girl hadn't see Mikey and just accidentally bumped into him. Her scream came from her surprise at the fall, not her surprise at four mutant turtles.

Knowing he screwed up, Mikey quickly backed up into the alley. He smiled sheepishly at his older brothers.

"Whoops."

All three of the turtles, simultaneously, glared at their younger brother for doing something so stupid. Before anyone of them could return to the shadows, though, the teenager began to stir again.

"Oh my gosh! I am SO sorry!" the young lady apologized. She was wearing a baggy jacket, jeans, and a red hat which had fallen to the ground the same time she did. In her attempt to readjust the cap back onto its rightful place, the girl hadn't looked any of the boys in the eye yet. Unfortunately, there was nowhere to go for them without being seen.

"I should have been looking where I was going. I didn't hurt your-" the girl started. She would have finished her sentence if she hadn't managed to see Mikey's green skin. The teenager's eyes widened. "Your… your… you're turtles…"

Raph simply rolled his eyes. "Nice going Mikey! Stand out in the middle of the street when cars are coming while you're at it." He sighed and crossed his arms. "Well, at least this girl had the decency to call us 'turtles' instead of frogs."

Leo shushed Raphael. He returned his gaze to the girl who was rubbing her eyes in disbelief. A thousand thoughts were running through his head.

"Why hasn't she run away yet? Did Mikey hit her too hard? Something's not right about her."

Nervous about what this girl might do, Leo raised his twin katanas slightly. She didn't seem to notice, but Leo's brothers understood right away. Everyone they had met so far had screamed and rushed off once they saw the turtles, except, of course, the bad guys. They couldn't trust this teenager.

Well, they couldn't trust her until she caught them by surprise.

"You're turtles? That is… SO COOL!" the girl shouted.

All four of their mouths fell to the ground. This wasn't right. People were afraid of them. People ran from them. People thought they were freaky. People did NOT think they were 'cool'!

And yet, this one girl said it out loud. By this point in time, Leo finally got a good look at her. She had short hair, hidden mostly by her hat, but a few dark brown strands hung by her head, framing a pair of chocolate eyes. The girl also wore black glasses, except they didn't make her look nerdy or anything. Instead, she appeared to be actually very pretty.

"Wait, what am I thinking?! This girl is suspicious. I need to focus," Leo thought.

"You… you think we're cool?" Donnie cautiously asked.

To their astonishment, the young girl smiled and nodded. "I've never seen man-sized turtles before! It's interesting to say the least."

"You don't think we're weird or freaky?"

"I wish I could say that you guys are the strangest thing I've ever seen, but I've seen stranger," she laughed.

She still hadn't made a break for it, so the brothers were left wondering what to do. Of course, Mikey did his own thing.

"Sweet! Someone finally realizes our awesomeness without us having to save them!" Mike declared.

Without a second thought, he ran up and hugged the stunned girl. All three of his brothers tensed in preparation of the girl's freak out. Instead, however, the teenager stood silently, contemplating what to do when a turtle hugs you.

Mikey soon released her and stared hopefully into her eyes.

"Will you be my friend?"

Still a little taken aback, the young lady blinked a couple times. Then, she smiled.

"Heh, sure why not?"

"Yay!" Mikey skipped around the alley. He squeezed the teenager once more and then went back to prancing about.

Mikey's new friend giggled. "Is he always like this?"

"You have no idea." Raph grunted.

She laughed a bit more. However, the girl suddenly stopped and whirled around. Her hands gripped the backpack hanging on her shoulders. For some reason, she became very uneasy.

"Are you alright?" Donnie asked.

He got no answer. In its place, the teenager mumbled:

"Shoot, I forgot. Not now. Maybe I should…"

Her words grew quiet and less clear. Leo started panicking about what she was talking about and grabbed his swords again. Even Mikey noticed something strange and ceased his prancing.

"Friend?"

The girl turned around, breathing heavy. She looked scared out of her mind. Before the brothers could do anything, she shook her head.

"I'm so sorry! I need to get going! My parents won't like me staying up this late on my own."

Saddened by this, Mikey whimpered. "But we just became friends. Will you come see us again?"

Despite her obvious fear of something unknown, the girl smiled warmly. "Of course! I'd love to talk to you guys some more, but I really have to go now. Bye, see you later!"

With that, the mysterious girl rushed away.

Michelangelo sighed. "Yeah, see you later. Hopefully."

Raph patted him on the head. "Don't worry. Your new friend will come back… if she wasn't running away from your ugly mug!"

"Hey! She was not! Like she said, her mom and dad were going to worry about her!"

"Hmph, yeah right," Raph snorted. "If she wanted to see you again, then why did she not give her name? When you want to meet up with someone, you don't run off without learning a few things about them."

Mikey gasped. "You're right Raph! I forgot to ask her name! Wait, which way did she go?"

Raph, Leo, and Donnie all smacked themselves on the forehead.

"Forget about her, Mike," Leo said, slightly frustrated at his little brother's foolishness. "We have a mission to think about."

Without anymore distractions (except for Mikey's constant moping), the turtle brothers carried on with their assignment.

Unfortunately, their little excursion cost precious time. By the time they entered the Reaper's den, he had been scrambling to somewhere else. For some reason, he wanted to move his base before he even knew the turtles were on his trail.

The brothers only got a glimpse of him before he ran off in a van. They tried to catch up, but there was too much ground made between them. Leo said that they would just go back to the lair and find the Reaper again. No one was thrilled about going back as failures, but the turtles had no choice.

The next day, in his panic, the Reaper left several skid marks to his new hide out. The brothers decided to set off once again that night. Everything was going fine, until Leo noticed that no one was at the place.

"Great," Raph complained, "what do we do now? Wait all night on a cold rooftop until someone shows up?"

"That's the only thing we can do," Leo explained.

"Do you think the girl is looking for us right now?" Mikey asked Donatello.

Donnie rubbed his head. "No, Mikey, I don't think that girl wanted anything to do with us! Sheesh, you've been going on about her all day!"

Mikey crossed his arms. "Well excuse me for being concerned for my new friend."

"She's not your friend!" Donnie shouted.

"Guys," Leo loudly whispered, "how many times do I have to tell you to be quiet?!"

"Leo, you know I'm right," Mikey whined. "She said she would be my friend."

Leo groaned. "Look, I told you to forget about her. Either she was just saying that to get away from you or she was mentally ill. Now focus on the task at hand!"

Even sadder now, Mikey sighed deeply. "I wish she was here. Then I could prove to you that she is my friend."

"You might just get your wish Mike," Raph said. He pointed down towards the street. "Isn't that her walking by right now?"

Mikey bolted to the edge of the structure, tripping Donnie. Even Leo ran to the side to see. Just as Raph thought, the mysterious girl was strolling down the sidewalk, nose buried in a book. She was wearing the same hat, jacket, and jeans as before, so it was easy to tell that it was her.

"What are the odds?" Leo wondered.

"She's here! Now I can prove that she's my friend."

Without waiting for a response, Mikey jumped down from the building.

"Wait! Mikey!" Leo yelled to him. "Ugh."

All three brothers leapt from the building after their rash younger brother. However, they were too late to stop Mike from reaching the teenager. He bounced off a trashcan and landed right before the girl.

"Hi, you remember m-"

He was cut off by the girl's scream. While she was sucked into her book, Mikey landed right in front of her, surprising the lass to say the least. In her panic, the girl stumbled over and fell right on her backpack.

"Ooof! Hey, what's the big idea?"

"Oh, sorry," Mikey apologized.

To make up for his lack of manners, Michelangelo lifted the girl up off the ground. Her eyes widened.

"Your skin…" finally, she looked the turtle in the eye. "Oh… it's you guys again! I didn't expect to run into you four here."

Mikey smiled as his brothers at last reached them. "Yeah, we're on a secret mission! Don't tell anyone."

Raph hit him across the head. "Not so secret anymore, is it?" He turned his attention to the girl. "Your friend here hasn't shut up about you since you met."

The young lady blushed. Just as she was about to say something, Mikey butted in.

"You left so quickly last time, I never got your name."

"Oh, right," the girl blushed even more, "Sorry about that. My name's Kaylin."

Mikey flung his arms around Kaylin and smiled. Then, he released her and gave her a thumbs-up.

"My names Michelangelo, but call me Mikey!"

Kaylin grinned and reached out her hand. "Nice to meet you… again."

Instead of taking her hand, however, Mikey grabbed Donnie and pulled him to Kaylin.

"This is my brother, Donnie. Well, actually, all three of these turtles are my brothers." Mikey pointed to both Leo and Raph.

Donnie stumbled a little when his brother brought him over. Slightly embarrassed, he took Kaylin's hand.

"Uh, hi. I'm Donatello, but you can call me Donnie or Don; whichever you prefer."

Raph grunted some. "Name's Raphael, but most people call me Raph."

With each introduction Kaylin beamed even more, happy to be making new friends. Even if those friends were turtles. However, there was a fourth turtle that hadn't given his name or even said 'hello'.

Everyone turned to look at Leo who stood several steps away, arms crossed and eyes glaring. At his stare, Kaylin shifted uncomfortably on her feet. He looked so mad.

"Um, bro?" Mikey asked, "You gonna introduce yourself or something?"

Leo switched his gaze to his brothers and heaved a frustrated sigh. "I don't have time for this right now."

Aggravated, Leo turned around and jumped back up to the building they were originally on. Raph folded his arms together.

"What the shell is wrong with him?"

"I'm not sure, Raph," Donnie said. "Leo doesn't normally act like that."

"Well, that is a very rude way to treat our new friend," Mikey snapped. He put his arm around Kaylin in reassurance. "That was Leo. His full name is Leonardo. Don't worry about him; he's kinda stuck-up in his ways."

Kaylin nodded, not taking her eyes off of Leo. Mikey noticed she looked a bit upset. He rubbed the back of his head.

"Hey Kaylin… uh, can I ask why you weren't scared by our appearance?"

Snapped out of her thoughts, Kaylin looked up at the three brothers. "Sure. Everyone says it's a bit cliché, but you can't judge a book by its cover. That's what I believe. And I wasn't lying when I said you guys were cool. You seemed… like some really awesome boys!"

Mikey, Donnie, and Raph beamed. It's not everyday that they got compliments like that, especially from a normal human.

Now, both Donnie and Raph started to like this girl. She seemed sincere and friendly. Maybe they could become friends? You never know.

Mikey wanted to find out more about Kaylin.

"So were your parents mad when you got back home yesterday?"

Kaylin gazed up at Mike, giving him a look like he was crazy. Quickly, though, she changed her expression.

"What… oh! Um… yeah. I mean no," the girl explained. "They were still out of the house when I got home, so I didn't get in trouble." Kaylin glanced at a clock inside another building. "But if I don't get back soon now, they might catch me this time."

Suddenly a little nervous, Kaylin grabbed the book she dropped and threw it in her bag. Mikey whimpered.

"You're leaving so soon?"

"Yeah, I'm sorry," Kaylin heaved. "It's was really nice getting to see you again and getting your names. I hate to rush off like this, but I have no choice."

"So, are we going to see you again?" Donnie asked.

Kaylin smiled. "Hopefully I'll run into you on another 'secret mission'." As she was about to go, she peeked up at Leo. Her eyes dropped a little. "And tell Leo I'm sorry for bothering you guys. Bye Mikey, Donnie, Raph."

Without another word, Kaylin ran off into the night. Once she was gone, all three brothers climbed back up to where Leo was sulking. Donnie couldn't understand why he was so angry.

"Kaylin says sorry for bothering you," he explained.

"Although, I don't understand how she was being a bother," Raph grumbled.

Leo glared at his younger brothers. "We can't trust her. What person in their right mind would not freak out when they saw us?"

Donnie fiddled with his fingers. "Kaylin said that she doesn't judge a book by its cover. She seemed really nice. Maybe you should give her a chance?"

"I don't need to 'give her a chance'. That girl, Kaylin, is a suspicious character we need to watch out for," Leo protested, clenching his fist.

Mikey puffed out his cheeks. "Oh yeah? Well I think you're just jealous!"

"Of what, Mikey?!"

"Uh, I-I don't know… but I know you are!"

Tired of his brother's stupidity, Leo threw his arms in the air and groaned.

"Well what's it gonna take for you to trust her?!" Raph spat.

Leo flung around, now completely fed up with this argument. "When she saves my life! How about that?!" Leo yelled. "Now come on! I checked the supposed hideout while you were talking and the Reaper already left again. It was abandoned. We're going home."

Heading back to the sewers, Leo stumped off, practically fuming. The rest of the turtles stood half in confusion and half in terror. Leo was always the level-headed one of the four, trying to stop fights instead of start them. Why did he snap now?

"Do you think he'll ever trust Kaylin?" Mikey questioned.

Donnie shrugged. "I'm not sure."

Raph crossed his arms. "Well, I'd like to make more friends than just April and a blind noodle man, so how 'bout we make him see things our way?"

Raph pounded his fist together.

"Nah we don't need that," Donnie said. "However, I would like to know more about Kaylin and why she's walking around alone so late at night."

"Let's ask her next time we see her!" Mikey exclaimed. "'Cause we will see her again!"

Who is this mysterious Kaylin? Why is she out so late? Why does she leave so suddenly? And why is Leo acting so hot-headed? The three brothers were left to ponder these questions. Little did they know what an affect this single girl would have on their lives.

How was it? What's going on with Kaylin? More importantly, what's going on with Leo? You'll see in the next chapter!
