I thought it could be useful if I add onto this blog periodically, jotting down any new information pertaining to the theming of Initial Personas.
Persona 2 & Persona 2: Innocent Sin: Greco-Roman Mythology
Persona 3: Greek Mythology
Persona 4: Japanese Folklore and Shinto
Persona 5: Breaking rules
Be sure to notify me of any future information, and I'll add it here.
