The cursed weapon that Lilith Potter's newest piece and sole knight, Ginny Weasley, was the host of turned out to be one of the lesser known ones. Specifically The Chikage, Blade of the Bleeding Moon.
Cursed weapons had their own system, which was quite similar to the Sacred Gear-system. And The Chikage was classified under the category of the Morph-type, causing a transformation upon speaking its phrase of awakening, which was in the case of The Chikage: Bleed 'em out… Chikage! Another type of cursed weapon was the Attack-type, which was quite obvious on how those worked. An example of the Attack-type was the legendary spear of the Celtic hero Cú Chulainn, Gáe Bolg, The Barbed Spear that Pierces with Death.
Anyway, Ginny's reincarnation consumed both of Lilith's knight-pieces, making her Lilith's sole knight. The cursed nature of The Chikage had corrupted Ginny's old dormant supernatural heritage and overwritten it with its own. Resulting in Ginny being reincarnated as what was known as a Sword-Devil, a Devil magically fused with a cursed weapon on an intimate level, even if the weapon in question wasn't a sword. Her figure, like the rest of Lilith's pieces, had started to develop at an accelerated rate, along with her kinetic vision and capacity to respond quickly. She was however nowhere near as buxom as her king or fellow pieces, yet. Fortunately, since her reincarnation was the most recent one in the British Peerage, her family didn't notice her more rapidly developing figure.
The games went well without any problems, even if most of the Devils, except for the most recent one, didn't really pay attention to the actual score in favor of what was happening on the actual field. Though the queen and bishop of the British Peerage had to slap their king back to her senses when the Veela-cheerleading squad of the Bulgarian team showed up, literally. While neither member of their little harem liked the idea of expanding it, including Lilith, it didn't stop the Devil/Reaper-hybrid from gaining a nosebleed, since Veela apparently attracted anyone who was attracted to women, regardless of their gender. Lilith might only have eyes for her girls, Luna and Hermione, but that doesn't mean that she couldn't resist finding other women attractive as well, even if she refused to do anything more than look out of loyalty to (and possible fear of) her girls.
It wasn't until after the games that trouble started stirring. Namely a combined assault on the fairgrounds from both Lord Voldemort's old forces and a rampaging stray devil. Fortunately for everyone, the simultaneous attacks happened on opposite sides of the fairgrounds. So the Devils let the wizards deal with Voldemort's forces, while they dealt with the Stray Devil.
Stray Devils were reincarnated Devils who no longer served a king and their demonic power had more often than not mutated into monsters. And this one was no different, having been mutated into a form resembling a freaky fusion between a stereotypical depiction of the Devil and Freddy Kruger.
Lilith couldn't hold back making a grimace of disgust upon arriving at the scene of carnage the Stray Devil had left behind. The fact that they had left bloody footprints behind them made finding the Stray Devil.
"Ladies." Exclaimed Lilith in a calm tone, despite the fact that her Peerage knew she was pissed. "I don't care how we kill this… thing. Only that we do it. Have I made myself clear?"
"Crystal!" Exclaimed the rest of the Peerage.
"Ginny!"
"Humph?"
"You're not partaking in this. Let the rest of us handle it."
"What!? But-"
"Think about it. You've only been a Sword-Devil for about a day whereas the rest of us has been Devils for at least a few months. Well, technically Rias and I've been what we are since we were born, but that's not the point. And I'm pretty sure that my cousin and her Peerage is here somewhere, ready to intervene if necessary. Take this as a lesson Ginny Weasley as you are no longer a human witch, as such you don't have to fight like one. You're a Sword-Devil now, and this is how Devils do battle." Exclaimed Lilith in a dramatic tone as a magic circle appeared underneath a stretched out arm. At the center of the magic circle was a triangle with a circle that was divided in two by a straight line. The mark of The Deathly Hallows, Lilith's personal crest (and possibly in the future, family-crest). From the center of the magic circle, a weapon was called forth. A triple-bladed scythe, the weapon of a Reaper, Lilith's personal scythe to be specific, which she affectionately calls Malthael. She had it forged earlier during the summer and trained herself to properly wield the weapon of the Reaper.
The British Peerage, except Ginny, engaged the Stray Devil, and the fight went rather well… that is until the Stray Devil sent the king crashing through a series of trees and the sole knight of the Peerage ran out of patience.
"*ROAR* that does it!" Screamed Ginny in frustration, summoning the cursed weapon she was the host of into her right hand. The Chikage, a katana-like sword. "Bleed 'em out… Chikage!" With the command to awaken the cursed sword, blood flew off the ground and started to cover Ginny while simultaneously shredding her clothes. Once the transformation was over, Ginny was now only wearing a skintight suit made of blood that only covered her privates, anything else was out in the open. With a disturbingly maniacal cackle, she joined the fray.
