Leo's Pov..
I'm running towards home and I could not stop thinking about Calli, I loved everything about her. How she didn't freak out when she saw me, her eyes, her laugh, and calm personality like me. When I was holding her hand, my palms started to sweat and my heart was racing fast. When she was cleaning my wound on my arm, when she was that close to me, I thought I was sitting next to beautiful angel from heaven. How her dark beautiful blue eyes were like lipid pools that shimmered in the night sky. Her curly hair with soft curls that rested perfectly against her with no effort, that would make any girl jealous of her. How her skin was silky smooth to the touch against my rough and dry skin. And her smile. Her smile really brought her out. It was caring and passionate that can make about anyone smile.

Wait what was this feeling? Do I like her? Am I falling in love with her? Many questions went through my head as I ran back home.

I jumped down from the last rooftop of the block and I jumped down on the darkened street. I ran across the street and made it towards the tunnel that lead to the sewers. I arrived back in the sewer tunnel and passed the Jeep and Raph's motorcycle. I walked towards the manhole cover that lead to the lair and I climbed down the ladder to my home, an abandoned subway station, to see my family inside doing their own things. Donnie at his work table doing some kind of experiment, Raph was eating on the lawn chair while lifting one of his dumbbell's in his hand, and Mikey was playing video games on the T.V.

I saw my father, Splinter, a gray rat a few inches taller than me, wearing a red, blue, and gold colored robe, holding his walking stick in his paw come walking into the room. "How was patrol Leonardo?", Splinter asked.

"Nothing too serious master, but I have to talk to you though", I said

Splinter looked at me surprised, but he nodded. "Come with me my son", Splinter said, walking off

I followed Splinter into the dojo and I closed the doors behind me and Splinter lit a candle in the darkened dojo. Splinter knelt on the wheat carpet and I knelt down on my knees in front of him as he placed the candle between the two of us.

"What is troubling you Leonardo?", Splinter asked

"Nothing is wrong", I said "It's just that something happened tonight"

He then noticed the bandage around my arm. "Leonardo what happened to your arm?", he asked, pointing

"Oh I got attacked by a Foot Ninja", I said, rubbing it gently "But someone helped me"

"Leonardo you know you are not suppose to show yourself to the humans above", he said, disappointed

"I know sensei, I'm really sorry", I said "But this girl who helped me, she was different"

"Different in what way?", he asked

"Well she was actually a ninja like me", I said

Splinter looked at me surprised. "Another ninja here in New York? That is quite a surprise", he said

"I know I was too", I said "But anyways though she was getting attacked and she was nearly killed by a Foot Ninja, but I stepped in and saved her. But the ninja who attacked her, came out at me and he sliced my arm. When he finally fled, she came up to me and what shocked me the most that she wasn't afraid of me"

"She wasn't?", he asked

"No she didn't find me terrifying at all", I said "Oh she was so beautiful, like an angel. I knew from the moment I saw her I knew she was an honorable kunoichi. She helped me healed my wound and we got to know each other more and we were a lot in common. She and I both have the same mission of protecting New York and the people above. She said she would never tell anyone of our existence and would keep her promise"

Splinter stroked his whiskers and waited anxiously for him to say something. "Well you did a good thing of helping that young girl Leonardo", he said "And I sense that we may have a new ally on our side, who has a special gift. Who is this young girl Leonardo?"

"Her name is Callista Sorrento", I said "She is about as old as me and the others"

"We should get to know this young kunoichi", he said

"Is it okay if she can come meet us all tomorrow?", I asked, hopefully

He thought about it for a moment then he looked back up at me. "Yes, she can come and meet us all", Splinter said "But only to see, if she is trustworthy enough that she isn't a danger to us"

I smiled happily that I got the answer I have been wanting to hear. "Great! Thank you so much master", I said, excitedly

"I will tell your brothers about our guest soon, right now you should rest after a long night of patrolling", Splinter said.

"Yes sensei", I said

I got up and I bowed respectfully, then I walked out of the dojo. I smiled brightly, happy that Splinter said yes. I couldn't wait for Calli to come and meet our family and I smiled as I walked in my room and I laid down on my bed, looking up to the ceiling, thinking about the beautiful kunoichi that I couldn't stop thinking about, Callista.

Calli's Pov….
It was around 7:45 in the evening and I was getting ready to go and meet Leo in the park. I was eager to see Leo again since I could not stop thinking about him last night. I decided to dress in my best outfit for him tonight. I dressed in a beautiful dark jade Japanese shirt with gold threads, a black belt, black silk pants, and gold sandals with jade gemstones. I put on my gold bangles and golden chain necklace with a jade ellipse around my neck. I put my make up on and tied my hair into a bun and pinned some of my bangs behind my ear and I let my longer bangs rest against my cheek. I stuck two dark wooden rods in the back of my bun and sprayed on some perfume on my neck and wrists.

I grabbed my katana just in case I ran into Foot Ninjas again and sheathed it in its hold. I walked downstairs into the living room, where Yani was meditating.

"Sensei, I'm going to go out for a while", I said "I won't stay out too late"

I then noticed that my sensei had a look of worry on his face while he was meditating and I became concerned. I walked over to him and I knelt down to his level and I shook him gently on the shoulders and he looked up to me.

"Master, what's wrong?", I asked, concerned

He gasped a bit noticing I was in the room with him and his look had changed.

"Oh, nothing is wrong my child, please be careful and have a good time", he said.

"Hai sensei", I said

I got up and I walked towards the door. "I wonder why he had that look of fear?", I asked, to myself "I hope its nothing bad happening".

I walked out of the house and I walked to Central Park, across the street from home and went to the big oak tree, I was told to meet Leo there. And sure enough, there was Leo leaning against the trunk, looking around for me. I smiled seeing that he actually came and I started running up to him.

"Hey Leo, what's up?", I called out

He turned and smiled and I ran up to him and I gave him a huge hug. He laughed a bit and he hugged back tightly in return. We let go after a few moments and we smiled at each other as he set me down on the grass.

"Hey Calli, I'm good and you look great", he said, politely

I blushed hard. "Oh thank...you", I said, stuttering a bit

"You are quite cheerful today", Leo said

"I was just happy to see you again", I said, smiling

"I am happy to see you again", Leo said, smiling

We smiled at each other, but then we both turned away blushing embarrassedly. But then Leo turned back and I faced him again.

"So how was training? If you had any today that is", he asked, shyly

"Training was good today, I learned how to attack my opponent without my vision", I said

"That sounds awesome! Could you teach me that?", he asked

"Sure I would be happy to!", I said

We stared at each others eyes for a few moments and smiled. "Oh hey that reminds me while you are at here, my master and father wants to meet you", he said

"Oh really?", I asked, surprised

"Yeah I talked to him about you last night and he was fascinated by you and he said he wants to meet you in person", he said

"Oh well it will be quite an honor to meet your master", I said

"Great! Come on they are waiting for you", he said

"Alright then!", I said, smiling

So we walked out of Central Park and he lead me to a dark tunnel, taking my hand gently, leading me through the darkness. I blushed feeling his warm and soft hand in my own. I felt it sweating a little, but I didn't mind.

"So this is where you live?", I asked

"Yep this is my home sweet home", he said

He lead me to a manhole and he climbed down the ladder. When he got inside he offered me his hand to help me down. I took his hand into mine and I started climbing down inside. After climbing down the ladder, I turned and I gasped in amazement of their home walking down the steps. A huge subway car that covered some of the station, along with a couch, a TV set, a kitchen, and bedrooms for each of them.

"Oh my gosh! This place is awesome!", I said, excitedly "I can't believe you guys made this!"

"I'm glad you like it", he said, smiling

Just then a turtle with an orange bandanna, that cover most of his head, walked out from the subway car and I looked at him curiously. As he turned a little towards me and Leo, he then looked down, but then realized I was in the room as he gasped with wide eyes.

"Woah Leo! You saved a fox!" he said, walking over

I giggled and blushed a bit, hiding my mouth. "Oh my", I said, embarrassed "Leo who is he?"

"Calli, this is my younger brother Mikey, Mikey this is Calli", Leo said

"Hi there", I said, smiling

He smiled brightly and suddenly took me in his muscular arms and hugged me tight. I laughed a bit as he squeezed me towards him. "Wow you are a hugger!", I said, giggling

"I'm so glad to finally meet you!", he said, happily "Leo by beautiful you didn't say drop dead gorgeous"

I blushed hard in my cheeks. "Mikey come on", Leo said

I giggled and smiled, then two more turtles walked in one wearing a red bandanna, only covering his eyes, and another one wearing a purple bandanna that covered his whole head. "Woah who is the girl with the sword?", the red one asked

"Raph be nice, we have a guest", the purple one said

I giggled and the purple one came up to me. "We heard about you through our master", he said "You must be Callista"

"Yes I am, but you may call me Calli for short", I said, smiling "And you are?"

"Oh I'm Donatello, but you can just call me Donnie", he said "And that is Raphael, but you can just call him Raph for short"

"Hi its nice to meet you both", I said, smiling

"Its very nice to meet you", Donnie said, smiling back

"Hey what's up?", Raph asked, in a tough Brooklyn accent

"I'm doing great, now that I meet all of you", I said, smiling

"Well here sit", Donnie said "We can get to know more about each other"

I smiled and we sat down in the living room. Leo and I sat together on the couch while Donnie and Mikey sat on the floor across the couch and Raph sat down on a lawn chair. "Can I ask you guys something? How are you all like this? Not to be mean or anything", I asked

"Perhaps, I should tell you the story of our origin", someone said

We turned and looked to see a tall gray rat walk into the room, who looked and sounded very wise like my master Yani. I turned to face Leo. "Leo who is he?", I asked

"Oh Calli, this is our father Master Splinter", Leo said

"So you must be Callista", Splinter said

I stood up and I faced him. "Hai sensei wa, sore wa anata ga anata no ie ni sa sete itadaite kōeidesu. Soshite, wataashi wa sono Futto ninja kara watashi o hozon suru tame no jūbun'na anata no musuko ni kansha suru koto wa dekimasen", I said, bowing respectfully

He smiled. "Anata wa hijō ni reigi tadashī wakai joseidearu, Callista", he said

"Arigato, Master Splinter", I said

"You speak Japanese Calli?", Leo asked, surprised

"Fluently yes", I said, smiling at him "I guess those 5 years of learning the Japanese language from Yani is starting to pay off"

He smiled, then I sat down beside Leo again, still looking up to him.

"The story of my sons and I begins a long time ago. I was originally a human named Hamato Yoshi and I resided in Japan where I became an expert of Ninjutsu. When my friend Oroku Saki sought the affections of my wife Tang Shen, Saki wished to discredit me in front of her. I had lost my temper and the altercation ended our friendship culminating in a battle that burned down my home and killing Shen and seemingly our daughter Miwa. After moving to New York City, I had just purchased four pet turtles when I stumbled upon an exchange in an alley between two people. Seeking to silence, before I could share what I had been seen, a fight ensued and the canister the people had been carrying smashed open splashing both on me and my turtles with an mutagen called TCRI. As a result, I changed into a humanoid rat after having had contact with a rat upon entering the alley, while the Turtles took on my human characteristics. Realizing I could no longer live a normal life topside, I retreated to the New York sewers where I raised them as my sons and I taught them the ancient Japanese fighting art of Ninjutsu.

"Wow, that is so incredible!", I said, amazed "What a tale, it's like something you would hear of a Japanese legend in the Yamato dynasty"

"So, what is your story, my dear?", Splinter asked

"It is quite a long story Master Splinter", I said.

"Go on and tell us, young one", he said

"Well, I didn't always live in New York, in fact I didn't live in America at the time", I said.

The boys looked at me with shock. "Woah talk about a long way from home!", Mikey said

"Michelangelo, don't interrupt!", Splinter said, hitting his head with his tail

"Ouch! Sorry sensei", Mikey said, rubbing his head

"Please continue on my dear", Splinter said

"I used to live in Florence, Italy with my mother who was American and my father who was Italian, in a big house on the country side. But one night, a few days after I turned 4 years old, our home was invaded and attacked by the Foot Ninja clan and The Shredder. They demanded all our goods, but my parents refused and they attacked, my mother took me to the wardrobe and hid me inside telling me to be quiet. Then all of sudden I hear screams of my parents and got really scared, then there was silence. I was horrified to find my parents lying on the ground dead in a pool of blood. Before I could do anything two foot ninjas grabbed and took me outside, then one ninja took a lighted match and threw it inside and my home instantly caught on fire. They took me to the Shredder and he was going to kill me for being a survivor. But my adoptive father Yani Shen saved me before he could do anything and fought off the Foot Ninjas. He offered to be an adoptive father to me and I accepted it, so he took me home with him to New York City, and he taught me the ways of becoming a kunoichi that I am today. And I have been living in New York ever since", I said

A few tears ran down my cheeks and I sniffled. I felt an arm go around my shoulders and I looked to see Leo looking at me as he rubbed my hand gently. "I'm so sorry that happened to you", Leo said, sadly

"It's okay", I said, softly

He hugged me to him and I hugged him around his arm.

"Me too, that is insane", Mikey said

"I'm gonna make Shredder regret doing that to you!", Raph said, punching his fist into his hand with a glare

"I'm sorry Calli, we will be here for you, no matter what", Donnie said, putting his hand on my lap.

Splinter looked at me with concern and sorrow. "I'm so sorry for your loss, my dear", Splinter said "I'm sure you parents loved you very much and are blessed that they had you as a daughter"

"It's okay, but I thank you all for your concern, that means a lot to me", I said, wiping away my tears. "But anyways lets try to not make this visit emotional, we should try to make it a good one"

"Yeah let's do it!", Donnie said, smiling

"Well anyone ready for pizza?", Mikey asked

"How about I make some for you guys? I know how to since I took culinary class in school", I said

"Sounds awesome!", Leo said

I smiled and I walked into the kitchen and Mikey gave me all the ingredients that I needed to make the dough and flipped it in the air and did tricks with it by rolling it along my arms and shoulders, while the boys cheered as I sang a traditional Italian song used while cooking. I then used my katana to slice the pepperoni, salami, green peppers, and tomatoes in the air and they landed across the table neatly.

"Callista that was Shellidellic!", Donnie said

"You are like a ninja but for food!", Mikey said

"Thank you I still have my Italian touch" I said happily.

When the pizza was finished, I threw it up in the air and I took out my katana and I quickly sliced it making each slice landed on everyones plate. "Wallah", I said, blowing a kiss giggling

"Nice touch", Mikey said, laughing

I giggled and they each took a slice and bit into it and swallowed, and as they did they just froze, their eyes went wide and they all smiled with amazement.

"This is the best pizza I ever tasted!", Leo said, happily

"You said it, Leo!" Raph said

"I agree!", Donnie said

"Me too this is delicious!", Mikey said

"I'm glad you guys like it", I said, happily

I served myself a slice and I sat down between Leo and Mikey and I started eating. After eating, they showed me their dojo where they train. It was a bit bigger than ours and it had punching bags hanging from the ceiling, weights on the floor, and a huge sparring match arena.

"Woah this is awesome!", I said

"You up for a match against us, kunoichi?", Raph asked

I smirked playfully. "I'm up for the challenge", I said

Raph laughed. "You are going down!", Raph said

"We will see about that", I said

We took our positions in the arena and I unsheathed my katana from its hold, while the others faced me with weapons drawn. They gave me fierce looks and I gave them one back, gripping my katana tight. We waited to see who would make the first move and Mikey made the first one, spinning his tonfas at me. I dodge them and I roundhouse kicked them out of his hands. I kicked him in the chest, then I quickly ducked down and swept kicked him off his feet. Donnie came spinning his staff and I kept blocking his attacks with katana. As he tried to hit me again, I quickly sheathed my katana in its hold, and I quickly grabbed a hold of his staff. He tried to pull it back, but I twisted it to where his arms were behind his shell and I kicked him in the shell, letting go of the staff. He fell on his plastron, the Raph jumped out attacking me with strong force with his sai's.

I tried to sneak attack by jumping behind him but he was quick enough and he blocked my attack. I unsheathed my katana again and I used it to block his attack and my sword entangled with sai's. He struggled to get them loose, but I used my katana to turn his hands inward, then I twisted them more to where he was leaning down. Then I quickly turned my katana again the other way and his grips on his sai's loosen and I jumped and kicked them both and struck a punching bag. I swept kick Raph off his ankles and I held my katana towards his face.

He looked at me with shock. "Woah Raph you got your shell kicked by a girl!", Mikey said, teasing

"I can't believe this!", Raph said, shocked

I giggled then I faced Leo. He had his sword drawn in a firm fighting stance and I sliced my katana a bit in the air, challenging him. He gave me a glare then he charged me. I charged at him and we clashed our swords against each other. Leo snuck in a front kick and he kicked me in the stomach, making me stumble backwards. I grunted and I charged him again, but I didn't noticed a crease in the rug. I tripped over it and I fell against Leo, making me fall on top of him and making us fall on the floor.

Our faces were both just inches from each other and we both blushed furiously red as the color of Raph's bandanna.

"Aww that is adorable", Mikey said

I blushed more red and I quickly rolled off of Leo.

"I'm so sorry Leo...I...I...didn't mean for that to happen", I said, embarrassed

He sat up and faced me. "It's..alright Calli…no..biggie", Leo said, stuttering

I got up and I held my hand out to help him up. He took it and he stood facing me.

"Good...match", I said, stuttering

"Yeah good match", Leo said, shyly

I smiled a little, then I looked out the dojo and saw on the clock in the living room to see it was 11'o clock. I sighed a bit disappointed, since time had flown by so quickly.

"I think I should probably get home, it's getting late", I said

"Wait Calli before you go", Donnie said, handing me a cell phone that looked like a turtle shell "So you can contact us whenever you want".

"Thank you", I said, smiling

I gave him a hug and he hugged back.

"I will walk you back home", Leo said, quickly

"Oh thank you I appreciate that", I said, smiling

"Bye Calli, come back soon as you can", Mikey said, giving me a huge hug.

I giggled feeling him squeeze the life out of me. "Don't worry, I will Mikey", I said, hugging him in return

"See you later and good match kunoichi", Raph said

"Thanks Raph", I said, smiling

He smiled back and gave me a playful punch in the shoulder. I smirked and I gave him one back, laughing a bit.

"Bye we had a lot of fun with you", Donnie said, smiling

"Bye you guys", I said, smiling and waving

Leo and I walked out of the dojo and we climbed up the ladder, out of the manhole. We walked out of the tunnel and through the park and walked up to the fire escape to my bedroom window.

"I really think my family is starting to like having you around, especially Mikey", Leo said.

"I agree, your brothers are awesome", I said, giggling.

He was staring into my dark blue eyes while I stared back into his brown eyes. I didn't even looked away with shyness this time, I was so mesmerized by his eyes. Something about them was just so different. They were so caring and gentle, that if you stared into them you would be lost in a spell that would be hard to come out.

"I really had a great time with you Calli", he said, softly

"And I did too Leo", I said, smiling "It was really...nice"

"I'll text you when I get back home, okay?", he said

"Okay", I said, smiling

He smiled and was about turn to leave down the stairs. But I couldn't let him leave just yet and I grabbed his arm with my hands and he stopped and I felt him froze as I touched him and he slowly looked back towards me with curiosity.

"Thank you Leo for everything you did for me", I said, lovingly "You are really something special"

"Your welcome anything for you", he said, shyly "Good night"

"Good night", I said, smiling

I gave him a sweet kiss on the cheek with my hand on his other cheek, before going inside my bedroom window. I closed the window and I leaned against the wall and legs couldn't hold me up and I slid down the wall to the floor and I sighed with happiness as I felt my heart beating faster out of my chest and felt heat rise out of my cheeks. "Oh my gosh, I think I'm in love", I said
