Index of the Lamp!

"Waaaah! Leave me alone!" Index shouted as she ran from the group of weird machines. "I am not trash!" It took a while before she somehow managed to lose them. She had wandered about the city for a long time afterwards, managing to get a bunch of nice strangers to feed her, including a nice blonde lady with stars in her eyes. Her name was Shoukou Misaki, and had a lot of nice people around them too. Index enjoyed their company, but she didn't want to drag them into her mess, so she eventually left. Wondering where she should go next, she put a hand on her head to rub her silver hair while she thought... only to realize she had forgotten her nun's habit back at Touma's place. Grumbling a bit as she started heading back, she kept an eye out for any of the mages hunting her.

Unfortunately, one of them had. A large and voluptuous woman with black hair in a ponytail, had approached her in an abandoned alley, with her sword at the ready. Index knew she wouldn't be hurt by the blade if her Walking Church was still working. However, after repairing it with clothes pins into her new Iron Maiden outfit, it no longer had the ability to protect her. So she did the only thing she could - run! Unfortunately, she was struck across her back with the blade, a large gash forming across her back.

She had no idea how she had managed to lose her pursuer after such an attack, but she eventually made it near Touma's apartment. Breathing heavily from her injury and her flight, she tried hiding in the bushes for her safety. She ended up almost sprawled on the ground, one hand on the concrete wall as her other went for the ground, suddenly finding something unexpected there.

"An... Arabian lamp?" She picked it up, looking at it. It could well be a trap from an unknown third pursuing mage, but she couldn't;t help herself. If it wasn't for what happened next, she would chastise herself for accidentally brushing it with her thumb.

"AAH~!" She gasped as she was engulfed in a silver blue smoke, a flail of her arm, dropping the lamp closer to the road pavement as she was engulfed. The lamp wrapped around her, focusing on her body first as it patched up her wound and dissolved her improvised outfit, converting it into a more genie appropriate attire. As Index was thinking through the tomes in her head to try and figure out what spell this was, the lamp followed suit, searching her past and history. It didn't take long for it to find something distressing.

This girl had been implanted with a spell setup of intricate complexity, designed to reset her memories every year, wiping away the previous one as easily as wind wipes away sand in the desert. It felt what could be approximated as rage at this - the spell even had connections to a couple of remotes that could activate an automated program, turning her into a weapon!

Unfortunately, this 'John's Pen' had been a part of her for so long, getting rid of it could cause problems. As much as it wanted to deny it, it was also a good self defense program, even if the motives behind it were vile. Then, the lamp had what could pass for a realization - the negation power it sensed. This girl knew the one who had it. It wouldn't be enough to remove the spell completely, but it could remove the automated mindwipe. And, the configuring of Index into a sex genie meant that the Lamp would be able to interfere with the automation of John's Pen, including the remote control systems. As odd as it was, the lamp had faith in this Kamijou Touma to save her, and so finished the transferring of information into her, before sucking her into the lamp.

Touma blinked as he processed this information with a dumbfounded expression. "So, you've been turned into a Sex Genie, who can grant me an infinite number of sex related wishes, in spite of Imagine Breaker?" He said, holding up his trusty right hand.

"Exactly Master!" Index said, already summing up how she preferred this new existence, including her new invulnerability. "So, would you like to make a wish?"
