A/N: I'm re-writing all the chapters... The next couple probably won't have anything to do with Blue Exorcist, but it's still going to eventually!

That day, eleven years ago, was a day I'd never forget. The day I met my best friend. My only friend. Since I was a small child, age four to be exact, even before I started pre-school, I've had a strange interest for the unknown. It started one day when I saw a ghost-hunting show that my older brother, who was ten at the time, was watching on TV. Rather than being scared of it, I found it interesting. Ghosts, demons, creatures that the human eye can't see. I wanted to know more about it.

Then when I started school, and when I'd talk about it to the other kids, they'd think I was weird. Therefore, they never wanted to be my friend. Everyone avoided me. The teachers even made me see a counselor, but my interest was undying. I resented the kids for not accepting me because of what I liked, so I worked harder on everything to prove myself better. I completely secluded myself from everyone else.

Then that day came. It was Saturday, so I was playing outside with a ball, which I was just throwing at a fence, so that it'd bounce back to me. A fun game you didn't need friends for. I'd keep track of every time I'd catch instead of miss. Each catch was one point, and each miss took one point off. I'd try to beat my record within a certain amount of time. But that day, my game was cut short. I saw a shadow appear on the fence from behind me of a tall female figure. Thinking it was my mom, I turned around. But it wasn't her. It was a... rather strange looking girl. She had the body of a human, but she was abnormally tall, especially for a Japanese girl who looked about eighteen.

She was deadly pale, and she two different colored eyes. Her right eye was white, and her left eye was a bright yellow. Her hair colors were also split. The right side of her hair was jet black, and the left was a bright pink. Her lips were colored black, and she had pink snake-bite stud piercings under her lips. She wore a lolita-like outfit. A tight looking corset and short flowy skirt. It was also split down the middle, the right side was black and decorated with white ruffled lace, and the left was pink with yellow ruffled lace. On her darker side, she wore a black and white striped arm warmer, and underneath it was a longer fishnet arm warmer. On the other side, she just wore a pink and yellow striped arm warmer and a yellow beaded bracelet. Same went for her stockings, her darker side was black and white stripes, with longer fishnets appearing ontop, and the brighter side was just the pink and yellow stripes. Her boots looked like they were made out of leather, and they had very tall heels. Again, they followed her pattern, the dark one being black with white laces, and the brighter one being pink with yellow laces.

I was scared. But she smiled sweetly at me, and knelt down so that she'd be closer to my height, "Do not worry." she said, her voice sounded so soft and sweet, and yet there was a small hint of darkness behind it, "I will not harm you." her face said she was genuine, but I wasn't sure if I should trust her. "Your name is Keiko, right? Suzuki Keiko?"

"H-How do you know my name?" I asked. My heart was racing. It felt like it'd pop out of my chest at any moment.

"Because I am what you would call a 'Shinigami'." she explained, "It's part of my job to have the names of all humans memorized."

"Wh-what's a... Shi-ni-gah-mi?" I asked, slowly trying to pronounce the new word as she did.

"Well, if I tell you, you have to promise you won't be scared, and let me explain it to you throroughly." I nodded, "A shinigami is a kind of demon who takes the lives of humans whose numbers come up. By that I mean, every human has a specific time to die, and when that time comes, a shinigami will go to them, and take their soul, officially pronouncing them dead." upon hearing this, I began to question why she was here. Was she saying it was my time? "However, we also protect the lives of those who aren't set to die yet."

"S-so then... Why are you... H-here?"

"Well... I've been on the working field for about half a year now. Life gets boring after a while of doing the same thing all day every day for six months, don't you agree?" I nodded in agreement, "I saw that you were lonely, and so I thought, how about we be friends?"

"Friends?" I looked down at the ball in my hand, "I don't need friends."

"You don't need to hide the fact that you're lonely, Keiko." she gently placed a hand on my shoulder, "I know you are. And I know how you feel. When I was in training, no one wanted to be my friend either."

"Why not?"

"Because I'm different from everyone else." she said, "You can say I'm an experiment that my boss wanted to test out."

"Who's your boss?" I was suddenly interested in this girl. She was a demon, afterall. And this was my first time being in contact with a demon.

"I'm sorry... I.. I'm afraid that if I tell you, I'll scare you off. So, I'll tell you when you're older." I nodded, "Oh, my name is Bittersweet, by the way."

"Bittersweet? That's an odd name."

"Demons, especially shinigami, tend to have names that are considered 'odd' to humans." she explained, "My name is an English term. It translates to 'Horonigai'"

We continued talking about random things. She told me a bit about what she does, and I told her about the things I liked. We laughed together, and she even joined me in my little game. We played together until my mom called me in for dinner.

"Keiko, sweetie, it's time to come and eat dinner!" she called out after I caught the ball.

"Okay, Mom!" I called back, "Do you want to join us?" I asked her.

At first, she looked like she wasn't sure how to answer me, but she finally gathered her words, "Actually, I don't eat." she laughed, "I should probably get going, anyway."

"Okay." I said sadly.

"Don't look so down." she patted my head and smiled, "I won't always be around because of my work, but I promise you, I will always come back to you. I can't give you a schedule because my work's times are random, but I will be here."

"Pinkie promise?"

She chuckled at my simple childlike ways, but she held out her pinkie, and I linked it with mine, and we shook on it. After that, she disappeared, and I ran back inside.
