Shigi is an inquisitor, a nun belonging to the Pope’s central office. Burning at the stake all devil worshippers, pagans and even believers who show misconduct is her mission.
She’s a passionate devotee to God and her strictness is second to none, even to Queen Claudette.
She has been given the authority to punish anyone that can be called heretic. It’s not that she has a cruel personality, actually she’s usually a virtuous woman, but she’s too serious and inflexible and doesn’t hesitate in judging people.
She’s very eager to burn down the Rebel Army that she considers to be a den of heretics. She sees their leader Annelotte, who carries demon blood, as an abomination. Also, she considers the use of Alchemy as a heresy (even the Pope’s central office has divided opinions on this topic).
She’s a user of the “Divine Power”, the manifestation of God’s miracles. For that she needs to perform the “Holy Poses” as written down on the sacred scriptures.
