__Introduction:__
Ai Kayano is a Japanese voice actress and vocalist currently affiliated with Office Osawa.

__Biography:__
Kayano wanted to work in a job that would involve "healing people", leading to initially take up a course at a vocational school. She worked in the beauty industry and became interested in acting after having seen [Aria](https://anilist.co/anime/477/). While attending school, Kayano continued working in the industry and paid for her tuition.

Kayano began working at Pro-Fit in 2010, voicing two supporting characters in the original video animation [Princess Resurrection](https://anilist.co/anime/9159/). In 2011, she voiced [Meiko "Menma" Honma](https://anilist.co/character/40592/) in [Anohana](https://anilist.co/anime/9989/) and received the Best Rookie Actress award for said role at the 6th Seiyuu Awards. Kayano, [Haruka Tomatsu](https://anilist.co/staff/95890/) and [Saori Hayami](https://anilist.co/staff/95869/) performed the series' ending theme "Secret Base – Kimi ga Kureta Mono (10 years after Ver.)", a cover of a song originally sung by the band Zone.

She is often praised for her vocal range, having voiced a variety of characters such as [Mayaka Ibara](https://anilist.co/character/55137/), [Mashiro Shiina](https://anilist.co/character/61371/), [Darkness](https://anilist.co/character/89363/) and [Akari Kawamoto](https://anilist.co/character/24311/) for example, none of which one would connect to the same voice actress.
