Best known for her role of Kiyomi Nagashima/Mitochondria Eve in Parasite Eve (1997). Riona Hazuki moved to Chicago when she was 9 years old and lived there until 1992, when she was discovered by a Japanese talent scout. Shortly afterwards, Hazuki flew back to Japan to begin a acting career. She started off as a regular in several Japanese television shows, before making the jump to the big screen in 1995 with the film Sharaku. Two years later, she got the role of the antagonist in the film Parasite Eve (1997), and has been starring in films from a variety of studios sense. Riona Hazuki has a rather nasty reputation for "fooling around," and has been spotted with several married men, such as actor Hiroyuki Sanada, who was later divorced by his wife (Satomi Tezuka) as a result.
