Ayasa Itō is a Japanese voice actress from Kyoto Prefecture, born on August 17, 1996. She is affiliated with the talent agency Hibiki and has been active in the industry since 2013. Her path to becoming a voice actress began when she was a junior high school student and participated in a dubbing experience at NHK Studio Park; the praise she received for her performance inspired her to pursue this career. To focus on her acting studies, she quit her high school activities in 2013. Her big break came when she applied for the "Milky Holmes Sisters Members Scout Audition," where she was chosen from a field of approximately 2,000 applicants. This victory led to her debut role as Alice Myojingawa in the anime Futari wa Milky Holmes, a part of the larger Tantei Opera Milky Holmes franchise.

Itō is widely recognized for several major and long-running roles in popular multimedia franchises. She is known for playing the pragmatic keyboardist Arisa Ichigaya in the band-based anime and game series BanG Dream!. This role extends beyond voice acting, as she performs as a keyboardist for the series' associated real-world band, Poppin'Party. Another significant role is Kaoruko Hanayagi, a traditional Japanese dance performer, in the Revue Starlight multimedia project, which includes an anime series, films, and stage productions. Her career began with the Tantei Opera Milky Holmes series, where she voiced Alice Myojingawa, a role she played across multiple seasons and adaptations starting in 2013.

Her filmography demonstrates a wide range of voice work in both anime television series and films. In addition to her most prominent roles, Itō has voiced numerous characters, including Rena Mōri in D_Cide Traumerei the Animation, Mukuge in In the Heart of Kunoichi Tsubaki, Asahi Nakamura in Joran: The Princess of Snow and Blood, Fighsly in I've Been Killing Slimes for 300 Years and Maxed Out My Level, Riko in The Demon Girl Next Door, Akane Suzumiya in Muv-Luv Alternative, Michi Sonoda in "Ippon" Again!, Kotori Shiratori in Taisho Otome Fairy Tale, Elfuda in Plus-Sized Elf, and Nao Koshiyasu in the Yatogame-chan Kansatsu Nikki series. Her work also extends to the D4DJ Double Mix project as Rika Seto, Mewkledreamy as Maira Tsukishima, and various BanG Dream! short-form series and films like BanG Dream! FILM LIVE 2nd Stage and BanG Dream! Poppin' Dream!.

Throughout her career, Itō has formed recurring collaborations with fellow voice actors and production companies. She frequently works with Aimi, her partner in the singing unit Milky Holmes Feathers formed for the Tantei Opera Milky Holmes franchise. This partnership continued in BanG Dream! and expanded into a joint YouTube channel called "Three Voice Acting Sisters [Team Y]" with Aimi and another voice actress, Mikoi Sasaki, which they started in April 2020. Her long-standing association with the talent agency Hibiki and production company Bushiroad has led to her casting in numerous projects from that stable, including BanG Dream!, Revue Starlight, Cardfight!! Vanguard, and D_Cide Traumerei.

One of Itō's notable achievements is her integration of voice acting and live musical performance, particularly through her work with Poppin'Party in the BanG Dream! franchise. This has allowed her to perform in concerts and contribute directly to the music of the series. Her career, beginning with a highly competitive audition win, showcases her sustained success in the voice acting industry, with a steady stream of roles across anime, films, video games, and audio dramas since her debut.
