Fujiwara served as an assistant judge within the Magical Law Association. Assigned to the Arcanum prison, he met his death during an incident involving a haunt. Toru Muhyo characterized this haunt as relatively weak and questioned Fujiwara's competence due to this outcome. Despite perceptions of incompetence, Fujiwara was acknowledged for his diligent work ethic. Reiko Imai referenced him when contrasting him with Jiro Kusano. She highlighted that while Fujiwara displayed cowardice, he consistently exerted effort in his duties. This comparison emphasized Kusano's untapped potential, implying Kusano possessed greater innate bravery and talent than Fujiwara but needed to apply himself more rigorously.
