Chapter 1: In the Beginning.

Tohru stared hopelessly at the math problem Yuki had written on the paper in front of her.

"Sin² Ө + 6cos Ө 5. Find the value of theta. Yuki! This math is too hard!"

Yuki smiled reassuringly. "Miss Honda, its just elementary trigonometry. It may look hard, but all you have to do is subtract the five from both sides to change the equation into a quadratic. Then, plug in one, six, and negative five for values a, b, and c of the quadratic formula. Once you have those values, it should be relatively easy to solve for sine of theta."

Tohru's brow furrowed as she slowly worked out the equation. After a few minutes, she hesitated, her pen hovering over two numbers. "So… the answers are—"

Before she could verify the solution, Momiji barged into the house with a shriek of joy. "TOOOHRUUU!"

Kyo and Haru followed, more sedately.

"Hello, all of you! Dinner's still cooking, but it should be done soon," Tohru said, as cheerful as always.

"Good. I'm hungry," Kyo mumbled. He plopped down next to Tohru and peered at her work. "You forgot to change the problem into like terms. Right now, you're trying to solve for sine and cosine, but that's impossible."

Tohru's face turned bright red. "Oh! I can't believe I did something so stupid! I'll never graduate, Yuki. Never."

"Yeah, yeah. And your mom will be disappointed, and you'll have to work as a janitor for the rest of your life, and Godzilla will destroy Tokyo again, and then the icecaps will melt and the ruins of Tokyo will be submerged in water, and—" Kyo was cut off by a pillow pressed into his face by Haru.

"Get this damn pillow off of me!" Kyo's muted voice bellowed.

"Don't feel bad, Tohru. Kyo is insensitive to everybody," Momiji said consolingly.

Kyo's hands reached out blindly for Momiji, as the pillow was still smothering him.

"Don't worry Miss Honda. I believe what Kyo was trying to say is that one mistake isn't important. We all make mistakes. They help you learn. Next time you'll remember to change the problem into like terms. Here, let's go over it again."

Tohru beamed and picked up her pencil determinedly. They turned back to the sheet of paper placed on the table, while Kyo screamed for breath, since Haru had yet to remove the pillow.

"Haru, you can stop now. I think Kyo has passed out."

"So, why did you and Haru come over to visit?" Tohru questioned Momiji as she stirred the leek soup. Kyo and Haru were in the next room playing a video game. She could hear Kyo from where she stood.

"What the hell do you mean Game Over! I beat you!"

"You were playing the wrong person, idiot." Yuki's voice drifted through to the kitchen.

"Rin" He said softly. Then he perked up and added, "And for the food!"

"Oh," Tohru responded. "Rin's upstairs talking with Shigure."

"Okay then! I'll watch Haru beat Kyo until dinner's ready! See ya!"

Momiji skipped out of the room and left Tohru by herself.

That's weird, I feel hot all of a sudden. I hope I'm not coming down with something.

But the feeling passed very quickly and Tohru forgot about it as she resumed cooking.

Now, where's that cooking knife? I'm sure it's around here somewhere.

She found it on a nearby counter and grabbed for it, reaching it far more quickly than she normally should have. As her hand wrapped around the hilt to pull it closer, she spotted a fly buzzing about near her head. Without thinking, Tohru buried the knife into the wall, ending the fly's life with a single thrust.

Tohru tugged the knife free, plaster billowing out in a cloud of dust, and stared at the hole.

"What the hell did you do to the wall?"

Tohru gasped and turned around. Kyo was eyeing the hole, obviously bewildered.

"I AM SO SORRY! I PROMISE I'LL NEVER DO IT AGAIN! PLEASE DON'T BE MAD AT ME! I'LL PAY FOR IT TO BE FIXED, I PROMISE!"

Kyo walked over to the hole and inspected it.

"Don't worry, it's nothing a little duct tape won't fix. But how did you manage to drive it in so far? That must have taken a lot of strength … is that a fly wing? You hit a fly with a knife? It was either already dead or you were really fast."

"I don't know what happened. I had the knife and I saw the fly and suddenly the knife was there and the fly wasn't."

Kyo walked over to some drawers. "Where do you keep the duct tape? It used to be in this drawer with everything else."

"Oh! I alphabetized all the drawers and their contents. It's in drawer D-F, over there, by the refrigerator."

Kyo muttered, "That's a little over the top"

"Why? I couldn't stand how cluttered everything was, so I cleaned the whole thing out."

"How did you hear me? Oh never mind, I'll get the tape."

Kyo looked at the drawer's contents. Everything was immaculate and sorted neatly into little bins with labels.

"When did you do this? It must have taken forever."

Tohru didn't answer. He found the duct tape in bin Dm- Dz, ripped off a piece, and covered the hole. "We'll find some wood filler later."

He turned around and saw Tohru standing there, still looking guilty.

"Don't worry about it! And I think the soup is burning."

Tohru hurried over to the soup and squealed, "Oh no!" She rushed to save what was left of dinner, the knife incident gone from her mind. Kyo watched her for a few seconds and turned to get the drink he had come in for, then returned to the living room, determined now to beat Haru at that damned video game.

She continued making dinner, a dim part in the back of her mind noting that she could sense all the people in the house: Momiji, Yuki, Kyo, Rin, Haru, Shigure, and… Hatori? She hadn't realized he was planning to visit that night, let alone that he had already arrived. They all felt like…animals. She was hearing, seeing, and smelling things she logically shouldn't.

···

Hatori had indeed come over for dinner. Dinner was simpler than usual because of the burnt food, but still as delicious as ever. Rin and Haru had gone upstairs to talk. Hatori hadn't said why he had come over, and Shigure couldn't help but tease Hatori of being a naughty old man infatuated with Tohru. Hatori had simply rolled his eyes in disgust and continued to eat.

After dinner was finished and the dishes cleaned, Hatori asked Tohru to come with him outside, away from eavesdroppers. A confused Tohru followed and they left with Shigure calling out locations where the wedding could take place, and hadn't stopped until Yuki and Kyo hit him.

"Tohru, I know this will sound crazy, but there's no way to say it except straight out. I've been informed that you have become one of many Slayers, girls imbued with the strength and skill to stop the powers of darkness. I am not a Watcher, but I will train you to slay vampires and their ilk."

"Eh?"
