Onechanbara DLC (UPDATED)

I was checking around to see if anyone had posted a video of the various unlockable Onechanbara costumes since I only want to focus on the ones that look good and came up empty. I did happen upon this DLC listing on the XBL site.

According to some other posts, there are other DLC out there as well. The only catch is they all cost money. Only this Aya "Legacy" costume is free. I'll look into the next time I log in from my console.

Update:
Quick pick from the official site. Also pictured are three characters you can purchase and play as.
