"So this little thing is supposed to make my magic stronger?"
That's what Lucy Heartphilia asked the traveling merchant in front of her. In between her fingers was a tiny lacrima, slight ovular in shape, and blue in color.
She had seen this shop come in from nowhere, and curiosity beckoned her to check it out. Leading here.
"Oh yes Miss! Accessories like these were incredibly popular with women in the eastern countries! They increase ones magic power, and men adore them! And this little bauble will only cost 500 jewel!"
"Huh, cheaper than I expected. You know what? I'll buy it." Lucy placed the money on the counter before her. "So how does this thing work exactly?"
"Oh, you must place it within your navel."
"...Seriously?" Lucy didn't want to believe it.
"Like I said, it's popular the eastern countries, and they were mostly deserts. Lots of exotic dancers."
"Well, thanks anyways." With that, Lucy walked off.
Behind her, the merchant pulled out a communication lacrima. Someone on the other end picked up.
"Did she take it?"
"Yes sir. Soon enough, our master will be reborn."
(That night, Lucy's home)
Lucy had just finished writing another letter to her deceased mother, having changed out of her usual clothes and into her sleepwear. She stretched out a bit as she put her pen down, and saw the tiny lacrima on the side of her desk.
"...Oh why not? If it works or not, no real skin off my back." She pulled her t-shirt up enough to expose her belly, then slipped the object into her navel. Oddly, it felt refreshingly cool.
"Hmm, don't really feel any different."
She stood in front of a mirror in her room, and she posed for a bit, flaunting how she looked. "Not bad. This thing suits me."
At that moment, she was hit with a wave of drowsiness. Deciding to pack it in for today, she crawled into her bed and sleep soon took her.
Under her blanket though, the lacrima had begun glowing, and after that, her belly began to gradually puff up and outwards, causing her shirt to ride up slightly.
The lacrima was absorbing the magic energy from the air and adding to Lucy's supply, but all the excess power was making her belly grow much larger.
All the while, she was just blushing and rubbing the growing orb.
(What's next?)
