Taking the RPG mobile game Persona 5: The Phantom X (hereinafter referred to as P5X) as the research object, this paper analyzes the language use characteristics of five main characters based on Satoshi Kinsui’s concept of “role language” and its indicators. The purpose of this paper is to make up for the current lack of research on role language in the game field and provide a reference for Japanese language teaching and game localization translation.
