Card Lores:Black Shiver, Gavrail

She is the captain of "Black Gravers", the special force of "Angel Feather" in black clothes. She stays in the capital garrison team because an especially great amount of patients are transported to the capital. She was given the frightening title "Shiver" before she joined "Black Gravers", from the fact that simply her presence on the battlefield is scare away the enemies. This extraordinarily dexterous lady can use multiple medical armament simultaneously, while common people can only use one at a time. She had fought well against the rebels, but she fell into the enemies' trap that her hospital was taken hostage. Under the promise that her patients would be kept safe, she surrendered to the rebels.
