Magical Girls

From the introduction: Magical Girls are often part of an ‘ancient’ group - knowingly or not. In Mariann: Soul Detective, we introduce the ‘ancient’ group of the SOUL DETECTIVES. But we didn’t go into detail about this group, because we want the Soul Detectives to match with your idea of an ancient group that protects the balance between the living and the departed! The group is what you make of it!
