Sorry for snailing on you all. >.<
The Plot will still be the same, we'll still do it in cannon world/setting, but we'll give some restrictions. First of all:
No Arrancar = Arrancars are actually rare, until they're mass produced by Aizen.
No BANKAI = All profiles having a Bankai, Please remove it, or stripe it, as the very move will be locked. No one can afford to have someone that constantly transforms into a form that runs over and violates SS in one arc. As all captains have bankai, except for Zaraki, of course. but they'll pretty much gangrape you themselves on their.
No Neo-Quincy, at least until we get there. = Well, Neo-quincy is actually a new regime, if you don't know what that is, feel free to ask. All quincy profile are considered the Traditional kind. You know, Bow & arrow, ginto, seele schneider. But, no spirit weapon and Volsandig before the time skip.
No Vizards = All Vizard made profiles will have ALL their Vizard/Hollow Powers locked, and will be counted as Shinigami, at least until the start of Arrancar arc, where they're actually used. And No Accidental Releases of hollowfications, either. ONLY KUROSAKI ICHIGO, as NPC, will have that right. But then, it's only valid until Arrancar arc.
Fullbring = Yes, full bring are allowed, but no one know that's it's called a fullbring. Mail me if it sounds confusing. Call it a "Chad" if you really need a name for it. (In the IC thread, of course. OOc: Calling it by its name is fine. A cat is fine too.)
Power level: Unknown will count as unseated level. Not like I want people to reveal their "Levels". Oh yeah, People in IC doesn't really know anyway. Anyone claimed Facing the head captain in the before the story will count as a Loss, A curbstomping humiliating loss. Long story short, He's teaching you a lesson. And for plot purposes, NO CAPTAIN LEVEL until the time is appropriate. It goes also with the no bankai rule. VC Level power will be achieved once you've beaten a VC level, and more or less the same thing for a captain. Just don't expect to beat the head captain.
Golden rule about the power Level: No OC is Stronger than Ichigo Kurosaki: He might be an NPC, but he remains the main hero. So, no "being stronger than him" kind of game.
