How do you have Karin so quickly?

So no response on how the original poster got Karin so fast? I mean, the only way to get her seem to be from shops like group, arena, etc. Is the original poster topping up, and getting extra currency quicker because of it? I'm free to play, so if that's the case, what's the best set-up for an Earth that isn't paying money?

EDIT: If you need to know what ninjas I have, here's a picture: http://imgur.com/a/FCZmv

They might have, but they must've gotten super lucky to get the drops. I barely get ninja fragments dropping while doing those.

Getting seal scrolls is hard to do, though. I hardly ever get them. Either way, I still asked for help on a set-up. With my current ninja line-up that I posted, until I can get the ones put in this thread, who should I use?

So is that a good set-up or not? Since you said you're not really an expert. I'll try it out to see how it is, though.

EDIT: Just realized this set-up only really helps if I know what skills to have for my main to go into battle. I've mainly been using the three presets the game gives you as reccommendations, and usually I have trouble staying alive, unless it's a plot or elite instance, then I have no trouble at all.
