Natsumi Amuro is a Yamatian refugee, and a fairly new member of the Blades of Vigilance. Save for Natsumi and her little brother, her entire family was murdered by demons. She and her brother fled, though they were separated in the confusion. Natsumi's main goal is to find her brother. Despite her tragic past, Natsumi is quite a cheerful young girl and has shown affection to a few men in the Grand Alliance. She later turned out to be actually working as a mole for Vaetris L'andariel and the Eastern Horde in return for getting her brother back from demons.
