Theodosia
Theodosia travels with Yogiri Takatou as one of his companions, appearing prominently in Volume 2 and again in Volume 5. She's Euphemia's sister and carries the weight of having killed the first Sword Saint—a necessary act given the extent of his crimes. By the time of Volume 5, she's actively searching for Euphemia, her missing sister, and eventually tracks her down near the volume's start.
