"I told you earlier, I don't know where it is. There are thousands of books here and if yours happens to get lost among them, that's your problem." A figure recited without removing her gaze from the thick brown book she was holding. Dressed in what seemed to be nightwear, she did not look out of place in the dimly lit library. She wore a violet dress and a nightcap with a crescent moon attached to it. She looked like she had spent more time here than the hundreds of bookshelves towering over her.

"Now Pache, is that really a way to address the mistress of the mansion?" replied another figure, a silhouette in the candlelight, with a slight smile.

"Patchouli quickly lowered her book and peered over it with her enchanting purple eyes. Blushing slightly she shuffled a little and looked around her.

"Lady Remilia... How strange for you to be spending your night wandering down here. Is there something you're looking for?"

Patchouli respected Remilia, and was grateful she allowed her to live in the mansion. Here she could enjoy reading and writing books for as long as she pleases, with almost no interruptions. Remilia stepped closer, now glowing beside the candle, and looked at her closely. Remilia wore a pink dress, a mob cap and had short light blue hair. The strange part about her appearance was the black bat wings on her back, and the fangs resting on her lower lip.

"I'm looking for assistance. I've learned that this mansion isn't safe. Vampire hunters have been seen searching around Gensokyo the last couple of days. If I don't do something about them, they'll find their way here and a massacre is sure to unfold..." Remilia's tone had become much more serious, and her eyes flickered red as she clenched her fist tightly.

"Vampire hunters, huh? I'm sure they wouldn't mind bending their target criteria to taking care of witches, given the chance... I'll accompany you; we'll fight together like we used to do!" Patchouli rose to her feet. She won't let this library come into any danger, she thought.

"No, you mustn't come with me. I know it's a lot to ask, but I need you to stay here and keep some kind of defence. If they get hold of her, you know what might happen. We can't allow that kind of destructive power to be let loose in that kind of situation. Existence itself may be at stake here!" Replied the vampire pleadingly.

"I understand." Answered Patchouli after some thought. "Nobody will find out about her existence, never mind harm her. You have my word."

With a smile and a bow, Patchouli sat herself back down and picked up her book. Remilia, with a stil troubled expression, headed out of the library and out of the mansion.

"It's going to be a long night, but I'll make sure the hunters become the hunted."

She took a deep breath, and then shot into the air. Her wings spanned much further in width than her body did height. She glided away towards the lake besides the mansion, becoming nothing but a silhouette under the moon.

In the basement of the mansion, there was something so powerful yet innocent, it could unintentionally destroy everything in sight. When frightened, happy, sad, excited, depressed, almost any form of emotion you can think of... It becomes dangerous. This thing was Flandre Scarlet, Remilia's younger sister. With the mental age and physical appearance of a child, she loved games and wanted to play often. But Flandre's idea of playing was attacking people in full force and often dismembering or exploding them. She held the power to destroy any physical thing by simply clenching her fist.

She wore a red dress, a pink cap, had her sister's red eyes and blonde hair a little longer than Remilia's. Her wings were much more colourful, with different coloured crystals set on them.

There were sounds of footsteps getting louder and louder coming towards the basement. Flandre jumped up and hurried towards the locked door.

"Oneesama have you brought food? I've been waiting! Fufufu I hope its cake again!" Flandre was rambling innocently. It would be hard to notice how unstable she really is.

"Oh, so you must be Remilia's sister, I've wanted to meet you for a long time." Patchouli replied to the little girl, not unlocking the door but moving her face close to it.

"Huh? Who are you! You're not my oneesama! An intruder! Do you like to play? Play with me, play with me!" Flandre's eyes were glowing with excitement, and she started banging on the basement door.

"I live in the library here, I'm not an intruder! The lady has gone on a trip for a little while and asked me if I can keep an eye on you. How about I make you some cake? Then we can maybe play afterwards?" Patchouli had always been curious about Flandre, and after meeting her she was a little worried the girl might be too much for her to handle.

It's probably a stupid idea to bring such a powerful being out of her nest, Patchouli thought to herself. But if there's going to be an attack, it's best to make acquaintances sooner rather than later. If something happens and she gets out, she'll assume I'm an enemy.

With a beaming smile, Flandre nodded and Patchouli cast a strange looking symbol on the front of the basement door. Then, it flung open and Flandre skipped out happily. They both made their way towards the kitchen in what would be silence if it wasn't for Flandre's joyful humming.

"Okay, let's get started." Patchouli muttered unenthusiastically.
