Jo's history isn't clear and much if not all of it is secret. To some it seems like she's been around forever, taunting heroes and cutting them with her knives, drawing blood whenever she can manage to get in close. To others it's like she appeared like a whirlwind after being an absolute nonentity. The HPSC has no records of her, and any that the Japanese government might have had appear to now be erased.
Jo is a nobody and a mystery, and while rumors have spread regarding her bloodthirstiness and apparent desire to kill as many heroes as possible, no one appears to have seen her outside of her intense, violent battles with the various pro heroes she's gone after.
At least, nobody will admit it.
there's nothing there's nothing there's nothing there's nothing there's nothing there's nothing there's nothing THERE
There's footage of someone who looks similar to her visiting a cafe once, and of a tall, slender figure in the background of some villain encounters, but copies of these mysteriously disappear quickly after they are brought to light. A security film of a young woman with prehensile braids entering and leaving a hospital is present in the HPSC's records, but no one at the hospital in question reports ever seeing a figure like that, despite the footage being relatively close in time to the first appearances of Jo's battling against various heroes.
There's a grainy video taken by satellite of a girl with her build and shorter braids on the edge of a roof, but it's not clear whether it's actually her or if the blurry image is just an artifact of the bad signal and lack of clear lighting at the time.
And of course, there are the rumors of the genetically modified Nomu, made from corpses and preserved brains and modified with extra physical strength and agility and multiple quirks.
And some have made the observation that Jo appears to be uncannily quick with her braids, and even her movement in general, more agile and fast than any normal, non augmented human should be.
But so far, no overt connections have been made.
Jo hasn't been captured yet, seemingly able to escape most situations even when it seems likely that she would much rather stay and fight more. She doesn't like being trapped, apparently, and given her taunts against a certain Wing Hero, she doesn't think highly of those who are.
Wouldn't you like to know, bird in a cage?
Though of course Hawks isn't trapped. He's Hawks, the No. 3 hero! Surely, this woman must be delusional, with her taunts of him being a "caged bird" and all. Perhaps it is a statement against Hero Society in general, but one may wonder, what it is she knows about Hawks that leads to her apparent contempt for his situation.
She's still happy to fight him, and so far has managed to be fast enough to slice many of his feathers into pieces in midair. Some may be concerned that the hero too fast for his own good has met his match, but he holds his own, and this dance of blade and wing won't be done anytime soon...
Even with pressure from the HPSC and the emergence of Tomura Shigaraki as a figure in the world of villainy, and the odd coincidence that Jo seems to be aligned with his goals, despite the fact that they have never been seen together.
Who is Jo, and what is her connection to the League of Villains, if any?
Is she a tool for Tomura that he doesn't know he has, built out of a broken girl and whatever raw material was available to enhance her abilities?
Does she have a connection, in origin, to the man in the shadows, Tomura Shigaraki's Sensei, All For One?
If you have any inkling of what any of this means, you're either in the know or, probably, on a hit list.
Or maybe, if you're a Pro Hero, you'll soon find yourself on the business end of a very sharp knife.
But she'll draw it out first.
To make it fun.
Catch me if you can, bird-in-a-cage! You think your feathers will help you? You don't know anything.
