Okay, this isn't really a suggestion, it's more of a "This is what me and Korari have decided to do, but some details can be changed" thing.
So, here's how the rest of the plot is gonna work:
It starts in Nevermore City. Mika gets an appointment to see the mayor, which will lead to a ninja-ambush on him in his own office by the whole evil group. What they DON'T know, is that they are running right into the good side's ambush, because Cai has disguised himself as the mayor. So, then there is an all-out battle between both sides in the Mayor's office, in which Osi is killed by Cai. DO NOT INTERFERE WITH THIS FIGHT. I will not rp the whole battle at once, because that would take a LOT of space. This battle is some-what crucial to the next part of the plot. Once Osi is killed, the rest of the evil group will leave. After the battle, Cai will have a mental-lock-down, which will cause him to be unable to lead the good side anymore. Korari will take this as weakness, and decide to attack Windtown. However, the good side will win this battle, and then our plot will be over.
