Maria is a former S-rank adventurer who once carried the double name Gray. She serves as the teacher of Miriam, a member of Angeline's adventuring party. Maria is characterized by a blunt and coarse manner of speaking, often described as having a bad mouth. She is afflicted by a curse originating from dragon's blood, which causes her to cough frequently and limits her physical condition. Physically, she has long gray hair that reaches her waist and blue-green eyes. In the story, she takes on a supporting role as a mentor, guiding Miriam in her adventuring career. Her background as a retired top-tier adventurer implies significant combat experience and skill, though the dragon blood curse has diminished her active capabilities. Beyond her mentorship of Miriam, specific motivations or personal goals are not extensively detailed. Her key relationships center on her role as Miriam's teacher, and she interacts with other characters through the guild and adventuring circles. No notable character development or progression is evident from the available information. Her primary notable ability is her past status as an S-rank adventurer, but the full extent of her skills is not elaborated upon.
