Sedona

A tomboyish girl that appears in the second season. Angelique, J.D., Rayne and Hyuuga met her while travelling. After the Hidamari Mansion was burnt down, the group disappeared, and the Thanatos numbers increased, the people of Arcadia started to blame everything on Angelique and the "Aube Hunters". While the group was passing by a village, looking for a place to rest, a group of men cornered Angelique after she wandered off, trying to kill her due to their recognizing her as the "Queen's Egg". Sedona beat them up and saved Angelique. Afterwards, the group follows Sedona to her ship (of which she's the captain), where they stay for a while. She's rather skilled with the sword and she taught Angelique when she requested it.

When they first met, Sedona didn't want to tell Angelique her name when she asked, because they weren't friends, so she told her to just call her "Captain." When they parted, she gave Angelique the fighting clothes and the sword she had lent her for practice as parting gifts, and she told her she could call her "Sedona", as they were now friends.
