Agree with above. Hoard that koban. If you have Hakata, use him in this event. Bought a background or two when I first started and barely made it through the last Village of Treasures. Lesson learned the hard way. You don't want to miss out on an event sword because you run out of koban. In the meantime, there are a lot of nice backgrounds you can get from the events until you are sitting on a good amount.
