Anyway, double posting now, sorry about that. Here's how the real danger would play out. While on their own, the Reiketsu Gates would be a problem, a danger to all around them, and a disruption of the balance between souls. But they'd be manageable they could probably be closed through Kidou or Ginto rituals. However, the real problem would occur when and if they were to intersect.

If they grew large enough to intersect with another such gate, they'd grow much larger and by the same virtue as how the Reiketsu might react when close to one another.. ahem. They'd merge into one highly unstable gateway to.. anywhere. If you happened to walk into one of those.. you might get sent to the destination that either of them had while separate, or you might simultaneously get sent to both. The latter part, needless to say, would not at all be pretty, your soul would be rent asunder and completely disintegrated, not to mention your body.

And this brings us to Osaka, rather than having it just be destroyed for Kraven to show off how evil and scary he is. I suggest we go deeper into it and have it so that it wasn't destroyed by Kraven, not necessarily. Although he'd definitely have a hand in it.

What happened to Osaka from my point of view was that it was swallowed up by multiple such Gates intersecting along it's entire perimeter, making it be torn to pieces and sent all across the spiritual realms. Rukongai citizens might find a strange abandoned high school in the Zaraki District.. a large park might've suddenly appeared in Hueco Mundo.. and Yuanrang might find that an entire forest has been eradicated and replaced with a ruined Osaka district that appeared there practically overnight.

The people however.. they'd be dead, and their souls annihilated by the Reiketsu Flux. And here's the dangerous thing.. as Quincy could close the gates, they could also make it a LOT worse. Kraven could inflict damage by focusing upon one of these gates, and driving a symbolic wedge into the gaping hole and forcing it open even more.

If by any chance the entire human world would become covered by these Reiketsu Gates, it would cause all the planes to merge into one.. and then implode upon themselves in one fell swoop. Result? Total annihilation of all the spiritual realms AND the human world.
