Entries for different versions of Ryumynui.4★ - No. 0943: A bard who wanders from place to place singing stories from all over the world with her magnificent voice. Ryumynui dresses lightly to facilitate her travels, but from up close it is clear that the fabrics of her clothing are of excellent quality, and that they are adorned with exquisite embroidery. Her mannerisms and way of speaking also allude to her possibly having a noble background.5★ - No. 0944: A wandering bard who sings tunes full of epic tales. The stories in Ryumynui's songs stem from the books stored in the shelves of her noble estate located far, far away. She gained the urge to share the stories she had learned with others after devouring book after book, and her outgoing personality lead her to set off on a journey to do so. Lucille, the first escort she met as she was departing, became her partner and now accompanies her throughout the rest of her travels.6★ - No. 0945: A bard who is always in an excellent mood. Ryumynui has the ability to catch the attention of others with her carefree and radiant appearance. Her repertoire of songs consists of pieces based on historical fact that she has composed herself, which she then performs for Lucille once they have been completed. Although Lucille's reaction to the songs is always quite underwhelming, this is enough to satisfy Ryumynui with her work.
