~Aqua's POV~

We looked at was happening and saw Raph holding an unconscious  human girl. She had  long black hair with purple and blue tips and some hair covering her left eye. She had white shrink and her clothes were torn and dirty. Donnie went to her and examine her.

I got out of the pool and Leo did too.

"Donnie please help her... I-I don't want to loose her..." Aika begged Doctors with her ears perked down and some tears treating to fall.

"I'll do what I can baby sis. Come on Raph." He and Raph left to the lab with the hurt girl.

"Hey Aika come here." Leo call her over.

She locked at are direction and came over sniffling a little.

"Hey don't cry, what happened? And who's the girl your two brought?" I asked.

"What girl?" MikeStar came over too.

"A human girl that Raph and Aika brought back know that Splinter is going to get mad when he finds out." Leo said looking at Aika a bit serious.

I put a hand on Leo's shoulder to make sure he doesn't be to harsh on Aika but I understand why he would be a bit mad. "Aika can you explain what happened?" I asked her.

She nodded.

~Flash back in My POV~

I was doing the training run with Raph to get used to my powers and to discover new attacks I could do with my powers.

I threw a strong sakura wind at Raph but he dogged it.

"Ha! Better luck next time princess!" He mocked.

"I'll get you Raph!" I made a sakura sphere appeared and then it at him.

The sphere hit the floor closed to Raph's feet. "Wow! Too close."

"Tee hee" I giggled but I perk my ear up and moved the to side to side trying to locate where the sound I was hearing was coming from.

"What is it?" Raph asked.

"I hear something or someone... I think it's in trouble! Let's go!" I ran off with Raph following.

We jumped a few roof tops till we got to where I was hearing the sound. Raph and I looked to the ally from the edge of the roof top and saw the Purple Dragons cornering  a girl with black hair and purple and blue tips and part of her raid covered her left eye. She looked beat up and her clothes were torn and dirty.

"I'll say it once and I ain't saying it again, do as I say and we leave you alone for now." Hun said to the girl.

"I-I won't l-leasing to you a-anymore! I-I'm tired of w-working for you!" The girl told him. Her voice sounded familiar and looking at her kinda reminds me of someone but nonetheless we have to help her with out letting her see us.

"Oh? So you choose death?" Hun asked her advancing towards her.

"I d-don't care! M-My life is c-crap anyway!" The girl lowered her head. "A-And that w-way I can r-reunited w-with my o-onee-chan..." She whispered.

I heard what she said and gasped. 'Hikari-nee!' There's no denying that's her. I looked at the Purple Dragons and growled jumping down.

"Hey what are you doing?!" I heard Raph yelled  but I just ignored him.

I landed between the Purple Dragons and my onee-san. I looked at the Purple Dragons with my eye pupils thin and growling intensely at them. "Don't.you.dare. TOUCH HER!!" I road at them and attacked them blindly because of my intense rage.

...

After a while the Purple Dragons ran away, I looked back at my Hikari-nee, she was scared of me but I knew that it was of what I was. If I remember correctly she was afraid of animal and more of dogs because of something that happened when she was a little girl. She was afraid of other specific animals but there a lot.

I slowly got close to here. "Hey easy is me Tilana."

"Y-You're lying! T-Tilana is d-dead and l-last I remember s-she wasn't a-a mutant t-tiger thing!" She yelled at me with tears running down her cheeks.

My ears perk down, I never knew that my "loss" would affect her.

"...o-onee-san... Feari where are you going? Hikari seumbu asumete kimini ashitatera tsuyo..." I sung a bit.

She gasped lightly and more tears ran down here cheeks. "N-Nee-chan..." She said before passing out.

I gasped and ran to her. "nee-San hold on onegai! Raph help me pleas!"

Raph cam down of the roof top to were I was.

I looked at him with distress in my eyes. "Raph we have to take her to Donnie pleas!"

"Are you crazy?! First she's a stranger and you just broke the number one rule, second Splinter is going to kill us if we bring a stranger back after breaking the rule!" She said.

"She's no stranger! I know her and she needs help! I'll deal with father later but now she needs help!... Pleas Raphie... I beg of you..." Tears started running down my cheeks.

Raph sighed then nodded. "Fine"

I smiled a little. "A-Arigatou"

~End of Flash back, still My POV~

I dropped my ears a bit as looked at the others after finishing explaining what happened.

"So wait that girl is your childhood friend?" Mikey asked.

"Yes... Before ending up with you guys she was the only friend I had since the other kids didn't want to play with me and bullied me a lot because I was really sensitive... But thanks to Hikari-nee I wasn't that lonely and she even defended me."

"But nonetheless Sensei will be mad that you brought her and let her see you ." Leo told me a bit serious.

Aqua got up since her legs came back while I was explaining. She stud behind me and put her hands on my shoulders. "Maybe Sensei will understand."

"Understand what Aquamarine?" Sensei said appearing out of nowhere.

We all gasped and jumped a little. I stepped forward and lowered my head. I started to explain to Master Splinter what happened and he looked at me serious.

"Aika what have I told you about letting humans see you?" He said serious and mad.

"I-I know Master Splinter... But I know she's not a threat to us... Just pleas let her stay till she's recovered... I know we can trust her with are secret..."

Master Splinter sighed and started stroking his goat beerd. "Very well but you know you are grounded for a week and you are responsible of your friend."

"H-Hai Sensei." I bowed my head.

"Good, now I'll go meditate." And with that Master Splinter left to the dojo.

Every on stud silent for a few minutes till...

"Wow, bummer baby sis. I never thought Sensei would ever ground you in you're life." Mikey scratch the back of his head.

"How do you feel?" Aqua asked walking up to me.

"I-I'm fine it doesn't actually bothers me like it those to my brothers when they get grounded." I said to her looking at the lab.

Mikey noticed  and walked up to me too and putting a hand on my head. "Hey cheer up baby sis, she'll be ok." He tried to cheer me up.

"Yeah, Doctor is the best there is." Aqua backed him up.

I looked back at them and smiled a little.

"But Aika next time, try to help IN the shadows." Leo said.

"Ok ok I will." I said.

We all waited for Donnie to finish fixing up me nee-san. As we waited Aqua and my brothers asked me to tell them about Hikari-nee and me so I started telling them stories about the little time we've been together since I was 4 but that time we got really close since she was always alone because of her strong attitude and the fact that she tell you things straight despite her age but it didn't bother me at all that she was like that.

After a while Raph came out of the lab and told us we could going. Of course I rushed in first to the lab, I went in and saw her on the bed asleep. I went to her and looked at her, she had change even her hair, I think she dyed her hair tips. I looked at her chest and noticed she had them bigger than my, I instantly felt jealous that she grew up to be a sexy girl and I'm almost the same age as her only by months. But how the heck did she got to have a lot of curves than me?! And now that I think about it, Aqua haves even more curves than me to! Why do I have to be flat chested?! It's not fair (T-T).

I turned to Donnie. "Hey Donnie, will she be ok?" I asked.

"Yes but she needs a lot of recovery, her body is even more weak that I thought. I think she doesn't takes care her body." He informed me.

"R-Really?" I looked at Hikari-nee worried.

"Yes but don't worry sis I'll get her to in good health soon.

I turned back to him and gave him a warm smile knowing that my best friend is in really good hands. "That's big brother Donnie"

"Your welcome." He smiled.

I looked at my nee and with two fingers I stroked her cheek gently while the others watch. I noticed that someone was watching very intensely. I looked a bit to see who it was and my eyes landed on Mikey. He was watching  without taking his eyes off my nee for some reason. I thought he was just curious so I put my attention back to my nee. I still can't believe I have her right in front of me after all this years.

A few hours passed and I was still in the lab sitting on the table where my nee was laying. I didn't want to leave here, I was afraid that if I leave she might disappear and I didn't want that. I was so caught up in my thoughts that I didn't hear Mikey come in.

"Hey baby sis, you still here?" He asked me while he approached me.

I turned to him and smile slightly. "Mmm hmm, just keeping and eye on her. Did you need me for something?"

"Just that Master Splinter wanted you to have a training section with only Aqua." He informed me.

"Oh. Well um..." I looked at my nee again.

I heard a lightly chuckle from Mikey that made me turn to him. "Don't worry Ai, I can watch her for you." I smiled and got off the table and hugged him.

"Thanks Mikey, I leave her to you." With that I pulled apart from home and walked out of the lab.

~Mikey's POV~

When Aika left I looked at her fried and started at her for a while. 'Wow she's so cute and she looks cool too' I thought to my self as I kept watching her. I can wait for her to wake up...
