So here is what I have gathered so far
There is a sort of fighting in a pub (your char obviously doesn't have to be in the pub when it happens they can already be in jail or done something else somewhere else its your choice :P) then whoever is in the bar fight get arrested. They all meet up in a dungeon (idk if separate cells or just one main cell). They manage to escape somehow and are hunted because they literally just escaped and with Itachi and well in turn they become public enemy number one aw well for escaping with a wanted criminal. They are hunted in every way possible and (incorporating Rouges idea a bit) They go on a few adventures and all that fun stuff, banirtry, thievery and maybe murder if they get caught (with the hunters still following their trail) Eventually the hunters catch up with them and they need to get out of where they are taking refuge (probably a ruin) over time they become good friends and form the gang seeing that it would be safer for them all to stick together (maybe idk XD) for a while otherwise the those hunting them would catch one of them and eventually maybe catch all of them and they are in prison again.
Thats what I have gathered so far. It's obiously a quick rough rough draft since anything can happen to be honest. It seriously is just something i whipped up right now from what all of you posted all out together :3
