I'll read through all this tonight, don't have time just now but I'll quickly say you can butcher/mess with my plot all you like. And the Jakakumei is a band of guys who used to be squad members of Nobunaga, just one group of shinigami.

EDIT: Ok! I'm back and I've read through the stuff. So! first of all I'm gonna link my old RP so you can actually have a look since you seem happy to adopt a similar premise (Also you could probably get a few more players by contacting those who were in it)

Secondly we did have a plot twist that involved the Jakakumei breaking into central 46 and releasing Nobunaga from his prison (Much like Aizens prison) But I can't for the life of me remember the proper twist (It was something along the lines of Nobunaga wanted to be imprisoned hence why he went quietly) but either way we can put a new spin on it.
