The second girl is named Jo Ayara, and she happens to be the most interesting character in this fan-series. Jo Ayara is an Elite Maho Shoujo who is vastly different from most of the others. She made a contract with Kyubey long ago, and in this series, she makes friends with Rika and decides to take her along with her.
Jo is a young girl with short brown hair. She tends to stay in her "powered up" form all the time. In her "powered up" form, she wears a light-gray Maid Outfit, and black shoes with sharp points on the end used for delivering kicks that impale. She has two Maho Shoujo weapons. Her first one is a Metal Magician's Staff with a silver orb on one end, and a sharp blade shaped like a giant Needle on the other end. Her second ones are these smaller Needles, which she spawns to her hand and throws like daggers. Her Soul Gem, while in its "portable form," attaches onto her back, on the area right below her neck.
Jo's unique special ability is a myriad of Elemental Attacks. Its her special power, like Homura's Time Control and Mami's yellow ribbons are. Jo can fire powerful blasts of various elements (Fire, Electricity, Ice, Wind, Earth etc). She uses them in her attacks, and often times uses multiple elements at a time to combine their effects. She can fire them from either her body, or from her staff, though it usually is more powerful when fired from her staff.
Jo has a number of things that makes her very different from the other Shoujos. The first thing is that she is actually happy that she made a Contract. All the other Shoujos think of the Contract as a curse, but Jo finds it to be a gift. She is happy about it because making the contract gave her amazing special powers, and now she cannot be killed by conventional means (only destroying her Soul Gem will kill her now). Plus she loves the thrill and adventure and excitement involved when she has to go into the various Witch Barriers and face off against the various Evil Witches herself, it's so exciting to her. Finally, she thinks that Kyubey's motives to essentially preserve usable emotional energy is a just cause, and she wishes to help him with that. Not only that, but she also has a bunch of friends now, of the other Maho Shoujo's, and she likes that. This playful, and optimistic nature of her is what kept her as a Maho Shoujo for so long. Unfortunately though, it doesn't last forever, and soon she does fall into despair.
Jo almost acts like a Zealot to Kyubey's cause. She claims that making a contract isn't as bad as it seems, after all ,you even get a free wish, alongside these special powers and everything. She is aware that she might become an Evil Witch herself, but that isn't too big of a problem for her. After all, all she has to do to avoid becoming a Witch is just "be happy," which is easy for her because she is very optimistic and playful and kind. Throughout this fan-series, Jo tries to also persuade Rika into making a contract, although she doesn't pressure Rika into doing it, like Kyubey himself does. Rika does consider it from all these benefits, but knowing the other consequences, she has second thoughts, and doesn't completely agree that it is a good idea.
Another unique feature about Jo involves her Soul Gem abilties. If you remember, the Maho Shoujos can survive even fatal wounds, and cannot feel pain, as long as their Soul Gem is not destroyed, and remains within 100 meters of them. Like they can be stabbed, decapitated, shot, and other stuff, but as long as the Gem remains intact, it won't kill them. The original Maho Shoujos only merely used this ability to survive longer in battle. Jo, however, managed to find another good use for this Semi-Immortality. This isn't exactly a unique ability for Jo. All of the Maho Shoujos could probably do what Jo is doing, but they just choose not to. Jo simply found a much more effective means of using her Soul Gem powers.
After Kyubey explained to Jo about how her Soul Gem keeps her alive, Jo got creative and decided to use this in another useful manner. She used the blade-end of her staff to cut her whole self apart, and then installed these custom-made, thin, metal Brackets in between the spaces, then reattached them all. These Brackets come in pairs and are in between various spaces of her body, and the way they are made prevents the skin from reattaching when her Soul Gem heals her. That way, they stay physically separated, and are only held in place by a bonding that is somewhat loose. They are not too noticeable on her, especially since they are thin, and her clothing covers most of them. Jo has brackets on all the useful areas for them. Her brackets are in-between her neck, waist, shoulders, wrists, ankles, and the joints in between her hips and upper legs.
The advantage to this Bracket thing is that Jo can make herself split apart, and have all her severed limbs move individually, and then she can pull herself together whenever she desires. Normally a Maho Shoujo would have to cut themselves with their weapons every time they'd want to do this. Thanks to Jo's custom Brackets though, she can just make them pop off and on whenever. Her Soul Gem keeps her alive through this, and she can still move her detached body parts, as long as they remain within range of the Gem. It took her some practice to get used to this, but now she is extremely talented at this strategic bodily disassembly and reassembly. Perhaps she's a bit too used to it, as for she likes to fall apart too much, and that happens to her almost on a daily basis. She always keeps herself together when in public though, as to not scare others. But when she's among friends who know her, or by herself, she much rather perfers her limbs not being attached. The most common one for her is that she removes her head and carries it in her arms instead. Jo also has a suitcase full of spare Brackets. Should her limbs be completely destroyed, and she has to regerenate it completely, she can just install a spare one later so that she can keep disassembling herself. Also the Brackets on her arms and legs are labeled "Left" and "Right." This is so that when Jo is putting herself back together, she knows which is which and doesn't accidentally put them on backwards.
There are a number of advantages to Jo's special skill to fall to pieces at will. One advantage is quickly dodging through detachment. Like say a projectile is headed for her face. Then she can just remove her head, let the projectile pass by harmlessly, and then stick it back on. Another use is that it allows her to be in multiple places at a time, well at least some of her. She has a battle tactic for this called "Divide and Conquer" where she removes her limbs and let them fire her weapons at the enemy from another location, while the rest of her runs around somewhere else, serving as a distraction. She also uses it in battle by pulling off her head, charging it up with elemental energy, then throwing it at her enemy like a cannonball, causing it to do severe elemental damage to the foe. Also it is useful for her as for her individual pieces can fit into narrow or tight areas much more easily. When not in battle, she also uses this in other ways for fun, like tossing her head around, or detaching her lower half and having the two play around separately. All of this is how she abuses the fact that she can no longer be killed this way, thanks to her Soul Gem.
All of these qualities makes Jo an extremely skilled Maho Shoujo. She could easily outperform Sayaka and Kyouko, and is about evenly matched with Mami, but Homura could still easily overpower her.
