-Five POV

Red lights were blaring throughout the Academy, signaling that we have a new mission. Quickly, me and my siblings got ready and ran down the stairs to our Father.

"Attention Children! I found another one of the 43 babies from 1989. Your mission is to bring it here. From my research I can say that it is a girl and her powers can be very dangerous. Pogo can't drive you all the way there, so you have to walk the last few meters. You are not to harm her. " The old man explained to us.

All my siblings agreed and wanted to run out of the house but I stopped them by asking the old man," How does she look like? "

The others gave me a weird look and Luther spoke up, "Who cares how she looks like?"

"Well, how are you going to find a girl somewhere, when you don't know how she looks like? Use your brain for once." I told him and pointed to my head.

"Very clever, Number Five." The old man said and had cold but proud look on his face. "All we know, is that the girl is small and has h/c hair. She has a really pale skin, but we couldn't see her eyes."

"Now get in the car. Pogo is waiting. Remember Children, her Powers are dangerous." he reminded us and we all ran out to the car.

We all got in and Pogo started Driving. All the while, my Siblings wondered how she could be like. Diego and Luther had the same thought about her and her powers. They said that they think she would be lovely, but when she uses her Powers, you shouldn't joke around with her. Allison just thought about someone to talk about Powers, since she couldn't talk about anything like that with Vanya. Klaus wanted a Sister, that can talk about fashion with him and would help him with the ghosts he sees. Ben just hoped she would be nice and I didn't really care as long as she doesn't hurt us.

We drove for an hour and as Pogo stopped we were in the middle of nowhere. There was nothing else than the street and a big forest. I think we all got this weird feeling in our stomachs before Pogo turned to us and said, "You have to go into the Forest. I'll be here in the car and wait for you. Be careful children."

We all took a deep breath and got out of the car. We started walking and, surprisingly, Luther and Diego didn't fight about the leadership. Allison wasn't as calm as on other Missions. Klaus wasn't high. And Ben was in the back with me by his side.

We walked through the Forest and soon spotted a small abandoned house in the middle of it.

We all looked at each other and nodded. Silently, we made our way over to the house. Klaus began to whimper and we all turned to him.

"Ghosts?" asked Ben and Klaus nodded. Luther and I went to his side and helped him into the house.

It looked even worse from the inside. There was broken Furniture everywhere. And on the walls were little massages saying 'You're not alone' or 'He's here' all written in a black substance.

We walked further down the hall and looked into every room. No one was in there. We got to the last door. It was closed and everyone began to argue about who opens it. I rolled my eyes and opened the door. I stepped inside and the room seems to be an old bathroom. There is a sink that is broken, a toilet and a bathtub.

The Bathtub was filled with a black substance, probably the one that is on the walls, and in the Bathtub is a small girl in white clothes. She looks up at me and I'm amazed. She has h/l, h/c hair like the old man said and e/c eyes.

I give her a gentle smile and she gives me a small one back. It fades quickly as my Siblings step inside. She panics and her eyes turn black, even the white in her eyes is gone. Its all black. A shadow arises behind my Siblings and attacks them. I quickly rush over to her and try to calm her down.

"Hey, Hey. It's okay. We are here to help. We won't harm you. We just want to take you to a safe place." I told her and she calms down a bit. I look over to my Siblings and the shadows are gone and all five of them lay on the floor, breathing heavily.

I smile gently and look back over at the girl. She is shaking and I gently place my hand on her shoulder. She looks at me and her eyes turn back to their beautiful e/c color.

"What's your name?" I ask her and she dips her hand into the black substance and starts to write on the wall.

"Y/N. A beautiful name." I smile at her and she smiles back. My Siblings stand up and slowly walk over to us. Allison and Klaus kneel down next to me.

"Can you talk?" asks Allison and smiles gently.

Y/N dips her hand back into the substance and writes at the wall 'Not anymore' and looks back at us.

"Not anymore? How comes?" asks Klaus. Y/N wanted to dip her hand back into the water but stops and smiles softly at something behind us.

We all look in the direction and see nothing. Only Klaus jumps a bit, which means there are probably ghosts.

"A-are these your P-parents?" asks Klaus shakily. She nods and has her gaze still fixed at her 'Parents'.

"They say she lost her Voice as she was here alone all the time. They died 3 Years ago. They were at the mall and there was a robbery and they got killed by one of them. Y/N was here alone with her Grandmother but she passed away right after that." Klaus told us and looked back at Y/N. "I'm so sorry. We want to bring you with us. To a safe place with food, it's warm and you can try and learn to talk again."

We all looked at her with sympathy and she looked at us scared. She looked back at her 'Parents' and they seemed to be okay with it since she smiled in that direction. Klaus slowly put his hand out to help her and she slowly and shakily took it. We all stepped back, so she could get out of the bathtub easily. Right after she stepped out, she fell but I catched her in my arms. She seems to be passed out, maybe something about her Powers, so I picked her up and held her in my arms.

Ben took a blanket out of his backpack that Mom packed for us if we had to stay overnight and wrapped it around her. She was really cold because of the Water and lazily wrapped her arms around my neck, out of reflex I guess, and nuzzled her head in the crook of my neck.

We walked out of the house and walked back to the car. Pogo started the car as soon as he saw us and we all got inside. He quickly drove us home and as we were half way there, she wakes up. She looks around the car with half closed eyes and the nuzzled her head back in my neck while I rubbed circles on her back.

As we got home, everyone stepped out of the car. I stepped out of the car last and was met with the old men, standing in the doorway.

"Very well Children. Bring her inside, Number 5. Grace is waiting there." he ordered and I quickly went inside and brought her to the infirmary.

I left the room and waited in the hall for mom to come out. I hope she is okay. She's just an innocent girl. And I don't think she can control her Powers that good. Even if that what she did to my Siblings, at her old house, was pretty impressive.

Its been an hour until Mom finally came out. She smiled at me and said, "She's okay. Don't worry. She just needs a warm place, food and a good rest until your Father is doing some tests with her."

I smiled and nodded. "Can I see her? I don't want her to be alone when she wakes up." I asked her.

"Of course you can." she said and strocked my cheek lightly. I smiled at her and went inside to see Y/N, still passed out, on the Infirmary bed.

I sat down beside her and softly took her hand in mine. After about ten minutes she squeezed my Hand and looked around the room in confusion. She began to freak out, so I stood up and gave her a notebook and a pen, so she could write what she wants to say in it, and she did.

'Where am I?' she wrote onto the paper. I smiled gently at her.

"You are at the Academy. Here you get food, a bed, new friends and you get to learn how to control your Powers." I told her and she nodded and wrote something down.

'Who are you?' was written on the paper. My eyes widen in realization. We haven't told her our names yet.

"Oh sorry. I'm Five. Five Hargreeves. I can get my Siblings and you get to know them if you want to." I told her and she nodded and smiled.

I quickly went out and got my Siblings. They all looked surprised to see her awake and even a bit scared because of what they saw in the Forest.

"These are Number one, Luther. Number two, Diego. Number three, Allison. Number four, Klaus. Number six, Ben and Number seven, Vanya." I introduced them and pointed to each of them. They each gave her a little wave and smiled.

She starts writing something down again. 'Hey! Sorry about the incident in the forest. I just freaked out.'

"That's no problem, really. I can understand that you freaked out. I mean, we were total strangers to you." Klaus chuckles and she had a bright smile on her face.

After a while of getting to know her more and Mom giving her a warm soup, the old Man came into the room and told Y/N to follow him.

"I like her." Vanya said and everyone agreed with her.

It's been six years since that day. Y/N got the name 'Number Zero' from the old man and the name 'The Demon' from the Paparazzi.

She learned how to speak again and how to control her Powers. She goes on Missions with us and we have a lot of fun. She got her own room, that is beside mine, and she hasn't been adopted by The old man. That's why shes called 'Number Zero'.

Her Best friends are Ben, Klaus and Vanya. She is good with Allison and Diego, but Luther doesn't like her that much. Since she is 'Number Zero' and with that a 'Better number' than Luther.

I Actually asked her, a year after she arrived, if she wanted to be my Girlfriend... And she said Yes!

I only wish I could get back. Just because I wanted to time travel. Now I sit here with the dead body of the Love of my life in my arms. I should have listened to the old man. I wasn't ready. Not at all.

I miss my little Demon.
