Матільда Сент-Омер

Mathilde Saint-Omer is the previous owner of the title "Flame-Haired Burning-Eyed Hunter". She is shown in the flashbacks leading to the ceremony of Shana's ascent as a Flame Haze. She was Wilhelmina Carmel's friend and companion. The two were regarded as the greatest pair of Flame Haze, rivaling in power and referred to as a counterpart to the "Pair of Wings", Crimson Lords Merihim and Illuyanka. She was in love with Alastor.
