Manami Numakura is a Japanese voice actress and former singer born on April 15, 1988, in Kanagawa Prefecture, Japan. She is affiliated with the talent agency Arts Vision.

Numakura decided to pursue a career in voice acting during high school, inspired by a drama CD from a friend and her interest in the Gundam franchise. Her professional debut followed a successful audition for the role of Hibiki Ganaha in the video game The Idolmaster SP in 2008, a part that would define her early career and foster a deep, long-standing connection to the franchise. She made her anime debut in 2009 with a minor role in an episode of Gintama.

Her career features a wide array of notable roles across various anime series. She is known for characters such as Kohaku in Dr. Stone, Pieck Finger in Attack on Titan The Final Season, and Narberal Gamma in the Overlord series. Other significant parts include Takao in Arpeggio of Blue Steel - Ars Nova, Riko Kurahashi in Love Lab, Rio Nakamura in Assassination Classroom, Saya Endō in Dagashi Kashi, Hinata Sakaguchi in That Time I Got Reincarnated as a Slime, and Beelzebub in I've Been Killing Slimes for 300 Years and Maxed Out My Level. Her filmography also includes roles in Fairy Tail, No Guns Life, Magical Girl Raising Project, Adachi and Shimamura, and the Aikatsu! franchise, among many others.

Numakura has frequently collaborated with specific production teams and franchises, demonstrating her versatility. She is a core member of the cast for the long-running The Idolmaster franchise. Her role as Narberal Gamma in Overlord led to reprisals in related shorts like Ple Ple Pleiades and the crossover series Isekai Quartet. From 2013 to 2016, she was part of the voice-acting unit Trident, formed with Mai Fuchigami and Hibiku Yamamura to perform music for Arpeggio of Blue Steel.

In 2016, Numakura expanded her career to include solo singing, debuting under the Flying Dog label. She performed theme songs for series in which she also starred, such as Magical Girl Raising Project and Fuuka, and released two albums, My Live in 2017 and Ai in 2019. She announced the end of her solo singing career in late 2019 to focus on voice acting, holding a final concert and releasing a compilation album in February 2020. In her personal life, she married fellow voice actor Ryota Osaka in 2019, and they have a child.
