Harumi Sakurai is a Japanese voice actress and narrator born on October 21, 1982, in Tokyo, Japan. She is affiliated with the talent agency Office Watanabe. In addition to her main stage name, she is widely known by the alias "Kazane" (風音), under which she has performed extensively in adult video games.

Sakurai began her career in the early 2000s, with one of her first credited roles being in the Japanese dub of the animated series X-Men: Evolution in 2002. Her early anime roles included Delie in Bōken Yūki Pluster World (2003) and Kaoru Yoshimura, listed among her roles, though the specific series title Circlet Princess is not verified in the search results provided. In 2008, she gained attention for her role as Hayami Kohinata in H2O ~Footprints in the Sand~, where she also personally handwrote the diary entries featured in the animation.

A pivotal moment in her career came in 2010 when she was cast as Yuri Nakamura in the original anime series Angel Beats!. While the series' original scenario writer, Jun Maeda, was involved in the auditions, Sakurai was reportedly recommended for the part by director Seiji Kishi and sound director Satoki Iida. This role as a central character in a high-profile original animation significantly raised her profile and is considered a key factor in her later success in mainstream anime. She would later reprise the role of Yuri Nakamura for the crossover series Kaginado in 2021.

Throughout her career, Sakurai has built an extensive filmography, often taking on supporting roles. She has been particularly active in franchises and series adapted from visual novels and games. She voiced Miyuki Seta in The Qwaser of Stigmata II (2011) and played dual roles as Panya and Ranka Sena in Mashiroiro Symphony - The color of lovers (2011). She also provided the voice for Kitty Evans in a Tantei Opera Milky Holmes alternative special. In the Monster Strike franchise, she voiced Ayumi Fukuhara in the Rain of Memories arc.

Sakurai has been the voice of several recurring characters across multiple seasons of long-running series. In A Certain Magical Index, she voices the esper Awaki Musujime, a role she has played since the show's second season in 2010 and reprised for its third season in 2018. Another notable long-term role is Lisanna Strauss in the popular fantasy series Fairy Tail, a part she has played since 2009. She is also known for voicing HMX-17c Silfa in the ToHeart2 franchise, including the adplus OVA series, a role that also led to her participation in related radio dramas. In 2012, she voiced the character Luna Luna in Queen's Blade: Rebellion.

In addition to her anime work, Sakurai has had a prolific career in video games, often under her Kazane alias. Prominent game roles under her main name include Saya Tokido in the Little Busters! franchise and Mao Yasaka in Hiiro no Kakera 2. She has continued to be active in the industry, with recent roles in the anime Kaginado (2021-2022) and the game Blue Archive in 2024.

Sakurai is recognized for her vocal versatility, capable of portraying a wide range of characters from young children to mature women, and is particularly known for her skill with tsundere (initially cold but gradually warm-hearted) and older, more experienced female characters. Off-screen, she is known to be good friends with fellow voice actress Ryoko Ono. In the industry, she is regarded as one of the few voice actors who successfully transitioned from primarily working in adult games under an alias to securing a substantial number of prominent roles in mainstream anime.
