The fourth of the twelve Dominions belonging to the Gralsritter, an order of holy knights within the Septian Church. Despite her small stature and youthful appearance, Celis is both foul-mouthed and temperamental; not only will she send foes flying for getting on her bad side, but she'll even pick fights with those she deems worthy opponents. Regarding combat, Celis specializes in a fighting style that requires her to wield a giant templar sword—one that's roughly as tall as she is. She was initially quite skeptical of Van upon learning that Bergard had taken him on as a student. However, over the course of the incidents surrounding Almata and the Oct-Geneses, she has grown to be marginally more trusting of him.
