Nazuna Gogyō is a stage name primarily used by the Japanese voice actress Ryōko Ono. Born on June 22, 1977 in Yokohama, Japan, Ono is a prolific voice talent who has worked extensively in both mainstream anime and adult-oriented visual novels under different pseudonyms. In addition to Nazuna Gogyō, she is also known by the alias Rikka Kitami, a common practice in the Japanese voice acting industry to separate different types of work.

The name Nazuna Gogyō itself is an artistic combination of two Japanese spring herbs, "gogyō" and "nazuna," which reflects a deliberate choice in her professional branding. As Nazuna Gogyō, she has built a significant body of work, particularly in the field of visual novels and PC games. Some of her most notable roles under this name include Airi Sena in Mashiroiro Symphony, Erika Takezono in Princess Lover!, Amane Mochizuki in Kono Oozora ni, Tsubasa wo Hirogete, and Kazuha Migiwa in Yosuga no Sora. Other credits include Mio Suzuya in Friends and Rin in Hare Tokidoki Otenkiame.

Her work extends to original video animations where she has voiced characters using the Nazuna Gogyō name. These roles include Karin von Gielen in Uchū Kaizoku Sara, the title character Shion in Shion, Kana Sumiya in Aki Sora: Yume no Naka, and Hikari Satake in Jūgo Bishōjo Hyōryūki OVA. She also performed the role of Izumi Moriyama in The Karma Saiyuki.

While Nazuna Gogyō is associated with more adult-oriented content, the actress's primary professional identity is Ryōko Ono, under which she has achieved considerable recognition in mainstream anime. One of her most significant and long-running roles is Mirajane Strauss in the popular series Fairy Tail, a character she has voiced since 2009 across the original anime, its second season, and the film Fairy Tail: Dragon Cry. Other notable anime credits under her real name include Atsuko in the Minami-ke series, Iliya Arkadia in Sound of the Sky, and Kazuha Migiwa in Yosuga no Sora, a role she also performed under her Nazuna Gogyō alias in the visual novel version. Her career began in the mid-2000s with roles in shows like Kurau: Phantom Memory and Trinity Blood, and she has since appeared in major franchises such as Pretty Cure and Digimon.
