Mai Kashiwagi

Mai Kashiwagi (柏木 舞, Kashiwagi Mai) was a high school student and the daughter of Kōzō Tahara who is the only survivor from an expedition into Hell's Gate. As a young child, Mai showed signs of becoming a Contractor, causing beetles to spontaneously combust. Her father, Kōzō, who was a researcher for Meyer & Hilton, used seeds which he found inside the Hell's Gate to suppress her powers. He also erased her memory with the ME. Due to the seeds not lasting forever, her father spent all of his time in his office looking after the plant which would give more seeds if ever the one in Mai's wrist should stop working. Due to this her father was never home, and Mai had to look after herself once her mother died. There was a significant emotional detachment between Mai and her father and Mai chose to adopt her deceased mother's maiden name
