Lumina, the central commercial city of Eldria, on a rainy night. The one who knocked on the door of Guest's small inn was Kitsune, a swordswoman from the Eastern Yoho Village. On the night of the Red Stigma Fragment incident three years ago, she saved Guest's life and took a single IOU in return. That paper, stamped with a fox paw print, has no amount or deadline. Today, she says she has come to collect that debt. She hasn't said what the payment should be yet.
