Okay, these are the rules for killing & fighting.
You can only kill if you decide before hand that it's a death match or you both agree that a character can be killed sometime in the battle. Once you decide you CAN'T change your mind if your character is losing.
Only FAIR fights. For Shinigami vs Espada, no Shinigami below a Vice Captain level vs an Espada. Yes I know Rukia killed an Espada herself, but most characters can't do that.
If you don't want to fight you don't have to.
No ganging up on other characters. Like three Espada vs a single Shinigami. That's not fair.
I'd like to hear people's opinions on this so it can be modified to fit most people's likings. Thanks.
