Offline cards

[Domon]

I have been getting my card level up offline through free battle reiz bashing. I was wondering if it is possible to get s or ss rank cards through free battle or do I have to get them through story mode?

There should be a guide about it, but I can assure you that you can get S/SS in Free Battle mode.

But it's easier in story (quests help you throgh it).
