This is my first story so please be nice! My friend gave me the idea for this when she asked me what I thought would happen if I had been Mello's sister when I was about six. So this is what I came up with!

Prologue-

Mello P.O.V.

It happened just a few weeks ago. My parents were killed in a fire that was set after a robber ransacked our house. I just barely escaped the blaze, and just barely pulling my sister, Allegra, from it too.

We were stuck in the government's care for those weeks and trust me it was horrible. The police who are talking to you don't get that you're just a ten year old who was hiding in an upstairs closet and trying to keep your six year old sister quiet so you really didn't see anything that happened. When a man who called himself Watari came and talked to the cops and told us that we were going to live at a place called Whammy's House, I was pretty happy.

When we got in the car to go to the airport Watari told us about Whammy's House. How it was a school for genius children and that it trained them to become the next L. L is the best detective in the whole world. He was my hero and now he's an even bigger hero to me. If Watari hadn't come then I was going to run away with Allegra, and that wouldn't have ended very well.

Now, we're in a black town car and we're pulling through the gates of the orphanage. When Watari opens the door I hop out as fast as I can and race halfway up the steps before I turn around to watch and make sure that Allegra gets out of the car alright. She climbs out slowly and follows me up the steps. As Watari opens the door she grabs my hand and hides partially behind me. I follow Watari and lead her down the main hallway to the office.

In the office there's another old guy sitting at a desk. He greets Watari first; they seem to be old friends, before he turns to us.

"You're Mihael and Allegra Keehl," he said to us as he sat back down and opened some folders. I saw Watari slowly back out of the room and smile at me.

"Yeah, we are," I answered for both of us.

"I'm Roger, the caretaker of Whammy's House. Now, what would you two like to be called?"

"Mello," I told him. Watari had informed us of this so I had a name picked out. I looked at Allegra; she hadn't told me the name she wanted to be called.

"Astraea," she said.

Roger looked at her with a look of surprise on his face, "how do you spell that?"

"A-S-T-R-A-E-A," she spelled out slowly. "It's the Greek goddess of justice."

I rolled my eyes. "She's obsessed with mythology," I told Roger.

"You're addicted to chocolate!" she huffed as she crossed her arms and looked away.

I shook my head and turned my attention back to Roger who was watching us curiously.

Roger finally snapped back to reality and told us the classes we'd be required to take and the rooms we'd be in. He dismissed us and gave us a map to find our rooms.

We walked to the stairs and went up to the second floor. I walked my sister to her room, which was only about four rooms down from mine. I helped her unpack her stuff and left her reading one of her mythology books while I went to find my room.

I opened the door and found my stuff and a red headed boy sitting on the opposite bed playing on a DS. He looked up when I walked in and turned the game off.

"You are?" he asked me.

"Mello, and you?"

"Matt, you're my new roommate?"

"I guess," I said as I started to unpack.

"What do you like to do?" he asked.

"Beat people up, eat chocolate, mind games, and stuff like that. You?"

"Video games and cigarettes."

"How do you get cigarettes here?"

"You need connections."

I snorted, "what connections do you have?"

"Lots."

We sat in silence for a minute and then we began to talk about things that didn't reveal any of our pasts or our real names. I was watching Matt try and fail to beat a level on his game when I heard a knock on the door.

"It's open!" Matt shouted.

"Mello?" I heard my sister ask as the door slowly opened.

"Over here," I told her from my place next to Matt on his bed.

I watched her open the door and run in before she climbed up on the bed and settled herself in my lap.

"Who's the kid?" Matt asked while most of his attention was on his video game.

"My sister, Astraea."

Matt paused his game and they looked at each other for a minute. Matt poked her in the head.

"What can a munchkin like you do?" he asked her.

"I probley remember more stuff then you do! And I'm smart for my age!" she huffed and poked him back.

Matt was about to respond when a bell rung loudly through the hallway

"Dinner," Matt told us as he stood up and walked out to the hallway. Astraea ran up to him and I could tell she was already starting a bicker-fight with him as they walked ahead of me. This was going to be a hell of a life experience.
