Prologue:845-621-937

In a dark small room, where light could only barely pass inside and nothing could be heard except the rustling sound of rusty metals rubbing each other. Looking inside, two silhouettes could be seen, one was a guy sitting on a pile of junk, and the other is a little girl kneeling on the ground as if she's looking for something.

[ Hey, Erica! don't play with my stuff so much. You might damage some of them. haah... Just, come here, here sit on my lap. ] the guy said in a tired voice. He tapped his left thigh to indicate that the girl should sit in there.

[ Un! okay. ] she instantly stood up and walked towards him and followed his order like it was the most natural thing to do.

[ so Erica-chan what do you want to eat today? is there anything you want to? ] he asked while patting the little girl's head.

[ Un! I want French fries! ] she replied immediately.

[ Then, should we go back to our base? ]

(change perspective and location)

After traveling outside for a while, I and Erica decided to come back to our base.

In a junk-filled area, where all you can see were thrashes and scraps. I walked towards the middle of an area yet to be filled with anything but a few dust and dirt, I kneeled down and washed the floor in front of me with my hands. Just a minute after, an outline of a small Trap door could now be seen. There's a little gap between it, I put my fingers on that gap and opened the trap door.

[ Erica, you come first, But keep the door opened. I just need to make sure that nobody followed us. ] It would be dangerous if anyone but us would know about this place.

I checked my surroundings, making sure that no eyes are watching us. After a while, I finally confirmed to myself that there is no one.

[ Erica, I'm coming in now. ] I said to Erica. I went down inside the hole and closed the trapdoor from the inside. What I saw inside was a small square room with a large vault as tall and wide as the other three walls. I walked towards the large vault and in it's middle was a ship steering wheel like vault lock with eight handles and nine numbers are written inside, but the number 1 was written in the most middle part of it. I put my hands on the handles and steered it, I remembered when I first did this I was really afraid back then because I don't know how it works. But now that I already mastered it, it was now easy.

845-621-937, that is the vault's password.

The vault then opened.

[ uwaah..we're finally home Erika-chan. ] I said while patting her head.

[ Un! home! ] Erika said with a bright smile a

then she raised her arms while looking at me.

[ yes, here here. ] I carried Erika into my arms

and finally get inside.
