Hisayo Abe is a Japanese voice actress and singer affiliated with the agency hive-six. She was born in Hokkaido, Japan, on November 4, 2000. Her career encompasses both voice acting for anime and games, as well as a significant parallel career as a vocalist. A notable aspect of her artistic development is her training as a vocalist under the tutelage of I've singer岛宫荣子. In 2022, she was selected to be one of the two new lead vocalists for the long-running music project fripSide, marking a major milestone in her music career.

Abe's most prominent and frequently cited voice acting role is Love Kurumizaka, also known by the nickname Kurumitan, within the multimedia idol project Idol Bu Show. She voices the character as a member of the idol unit NO PRINCESS, appearing in various project installments including drama CDs, character songs, and the 2022 anime film adaptation titled Gekijō-ban IDOL Bu SHOW. Beyond this flagship role, her voice acting credits include the character Anna in the PC game Grisaia: Phantom Trigger vol. 8, and roles in other games such as Muv-Luv: Dimensions, Destiny Child, and Vivid World. She also provided the voice for the character Sheela in the television anime Seija Musou: Sarariiman, Isekai de Ikinokoru Tame ni Ayumu Michi.

A significant and recurring aspect of Abe's professional life is her work as a singer, which often intersects with her voice acting projects. In 2020, she performed the theme song te to te to te for the Kyoto Animation original anime Baja no Studio: Baja no Mita Umi. Her career as a vocalist became more prominent starting in April 2022, when she and上杉真央 became the new vocalists for fripSide. With fripSide, she has performed theme songs for television anime, such as the second opening theme for Mission: Yozakura Family, and has participated in major music events across Japan. This dual career as a voice actress and a high-profile singer, particularly her selection for fripSide, represents a key achievement and defining characteristic of her professional profile.
