"The acting guild master of the Aoyama Missionaries, the biggest guild in the 23 wards. She is also the vice president of the Daikanyama Academy Student Council in Shibuya Ward. She leads the ever expanding Aoyama Guild, which spreads from Minato Ward to Shibuya Ward and is comprised of Transients who have fled from other areas. She is a plucky nun whose strong will enables her guild to resist all the harassment aimed at them from the neighboring Roppongi Guild. She's been involved with the guild since they were still a volunteer group that provided welfare for stray Transients. As she never acts out of self-interest, she does not get along with entrepreneurial types concerned with wealth."
"She holds the Sanctified Nails Sacred Artifact that can transfer the pain and injuries of others to herself. She is best friends with Gabriel, the mascot and idol of the Aoyama Guild. In the past, she hated the entire world, but after experiencing a one-time-only miracle, she changed her way of life. She has lead a treacherous life beyond anyone's imagination. The name ""Maria"" is also not her real name. She considers those who bear the burden of their sins her comrades in arms. "
