Flandre was having a nice time with her new friend, Patchouli Knowledge when there was the sound of a broken window from above in the Scarlet Devil Mansion.

Patchouli sighed and sipped her tea. "Another book gone..."

Flandre frowned. "Is there any way we could stop her? She's annoying..."

Patchouli thought about this for a moment. "You said you were a Vampire, right?"

Flandre tilted her head as she started to get the message. "Yeah... So, if I was to bite her..."

"She wouldn't bother you again. In fact, you may even have someone to play games with." Patchouli mentioned as she put her cup down. "For eternity maybe."

Flandre's mouth turned a toothy smile as she stood up and spread her wings out, all the multicoloured gems showing. "That's it!" She giggled madly and took off into the heights of the mansion after the trail of a certain Black-White Witch.

At the top of the mansion, Flandre saw the "Ordinary Witch" standing there, with her back turned to her counting the books she had taken. She walked very slowly up behind her, so as to not startle her, and within a few moments...

1.

Flandre pounced onto Marisa and bit into her neck so deep and so quickly that Marisa didn't have chance to even get her Master Spark out. Only a scream and a muffled, "GAH! He-Help!" Was all she could muster as she fell onto the roof of the mansion, almost knocked out. "What... What the hell?" She managed to get out. Flandre fell onto Marisa also, making it impossible for Marisa to move really.

Marisa tried to move but with the weight of Flandre on her, she couldn't. She suffered as Flandre sucked some blood out of her and used both her fangs to push even deeper into the veins of the poor witch.

'I was only trying to get some books! ZE!' She screamed in her head as she felt her body start to fail her. All consciousness was failing but she refused to quit. Flandre pulled her fangs from Marisa after injecting a syrim that only she had in her - The Vampire Changing Syrum that would make her dear friend a Vampire Witch. Now didn't that sound appealing?

Meanwhile on the other side of Gensokyo, Alice Margatroid looked up from her doll crafting and went to her window immediately. "Marisa!" She could sense something was wrong with Marisa's magical energy... She was becoming immortal but... Not a good type. More of a Dark type. Alice shivered as she sensed it.

Alice raced out of her house, flanked by dolls of course, and headed straight for the Hakurei Shrine. If she was going to help her dear friend Marisa, well, Crush, then she'd need help - Namely in the name of Reimu Hakurei or maybe Yukari Yakumo, the barrier protectors.

Reimu and Yukari were playing cards when Alice came racing through the forest up the Shrine's steps and towards them. Reimu sighed. "You win, again. I swear its your gap abilities..."

Yukari smirked. "My, you compliment me too much."

Reimu stood up and looked to Alice who panted in front of her. "What's it this time? Marisa took a sewing pin?"

Alice frowned and marched even closer to Reimu, grabbed her by the shoulder and pointed her in the direction of the Mansion. "Feel that!? That's not normal Marisa, right?"

Reimu focused her senses after a moment of confusion and then both her and Yukari frowned. "That... Isn't normal... What's happened to her?"

Alice flailed her arms around. "I don't know, that's why we are going to find out!"

Alice grabbed Reimu's hand and dragged her skyward and towards the Mansion.

At the Mansion, Marisa's breathing slowed down until she couldn't even hear her heartbeat. It was odd, but whatever had bitten her was changing her internally. And it hurt. BADLY.

Marisa twitched several times as she rolled over. Flandre moved long ago and was watching from afar, giggling to herself.

Alice and Reimu arrived with Yukari in tow. Alice immediately going to Marisa's side as Marisa coughed. Time and again.

Alice panicked as she put her hand underneath Marisa's head. "Come on, Marisa, you're okay. What happened? Did you try to take a book again? Come on, sit up."

Marisa slowly rose to a seating position as Reimu knelt in front of her. "She's completely out of it. Marisa, hey, can you hear us?"

Marisa blinked. She couldn't hear nor understand her friends. Her two closest friends in the whole of Gensokyo and she couldn't talk to them. WHY!?

It was then that Marisa heard the giggling. Yukari heard it too. They both looked at the source, to see Flandre with blood down the side of her mouth with a twisted smile.

Marisa blinked. That was her blood, wasn't it... So... It stood to reason that... Wait a second...

Reimu took out her staff and she tried to heal Marisa's wounds but it didn't work. It only served to infuriate Reimu and Alice smiled at Marisa. "We'll work this out. You'll be fine."

Marisa winced. She could hear Alice now, her hearing was SIX TIMES as strong as it had been. Her powers were increased ten-fold and she knew Flandre could sense this... But, she felt a sense of... Familiarly to Flandre. Almost as though...

"Did you just..."

Flandre nodded slowly. "You keep stealing books. Hehehe." She giggled again. "So, I took the liberty of trying you into one of Remilla or Me type people!"

Marisa's eyes widened. "A vampire..."

"Uh-huh"

Alice looked between them. "What have you done Flandre..."
