Tomo Muranaka is a Japanese voice actress born on December 15, 1989, in Ibaraki Prefecture. She is affiliated with the talent agency Haikyō and began her career in 2008. Her inspiration to become a voice actor came from watching the magical girl anime Sailor Moon during her elementary school days.

Muranaka's career is marked by a wide range of roles across various anime series, films, and video games. In her early years, she gained experience in numerous supporting roles. A significant early lead role was as Yūma Kuga in the long-running anime series World Trigger, starting in 2014. She also voiced the character Daigorō Iwata in Kuromajo-san ga Toru!!.

A major milestone in her career was being cast as Aoi Tategami, also known as Cure Gelato, in the 2017 Pretty Cure series Kirakira PreCure a la Mode. This role placed her in the prestigious line of voice actors for the long-running magical girl franchise. She reprised this role in several subsequent Pretty Cure theatrical films, including Eiga PreCure Dream Stars!, PreCure Super Stars!, Hugtto! PreCure Futari wa Pretty Cure: All Stars Memories, and PreCure Miracle Universe, becoming closely associated with the character.

Her filmography also includes significant roles in high-profile projects. In 2018, she voiced Michelle Luio in the theatrical film Mobile Suit Gundam Narrative. She played the young sailor Sinbad in the 2015-2016 trilogy of anime films, including Sinbad: A Flying Princess and a Secret Island and Sinbad: The Magic Lamp and the Moving Islands. In 2020, she took on the role of Gō Mutō in the Netflix original anime series Japan Sinks: 2020. She also voiced the character Yoshimura in the 2021 series Megalobox 2: Nomad. Her work extends to video games, with notable performances as Poison in Soul Worker: Your Destiny Awaits, Aki Yamato in The Idolmaster Cinderella Girls, and Daniela Dimitrescu in the Japanese version of the global hit Resident Evil Village.

Muranaka has demonstrated a recurring collaboration with the Pretty Cure franchise through her multiple appearances as Cure Gelato. Her work on The Idolmaster Cinderella Girls is also a significant part of her career, where she is noted for her vocal performance and dance ability during live concerts, often singing in a lower register that stands out among many higher-pitched voice actors in the series. Her role in the Sinbad films also represents a sustained performance across a multi-part project.

A notable achievement in her career is her versatility in voicing a wide spectrum of characters, from young boys like Yūma Kuga and the young Sinbad to energetic heroines like Cure Gelato and more mature or mysterious women like Poison in Soul Worker. Her voice work in the gaming industry, particularly in a globally renowned title like Resident Evil Village, highlights her reach beyond traditional anime.
