Seria Fukagawa is a Japanese voice actress born on September 26, 1995, in Saga Prefecture. She is affiliated with the talent agency AXL ONE and began her career in 2014. Her path to voice acting was influenced by winning the Best Reader Award at a broadcasting competition during elementary school, which inspired her to pursue performing arts. She later moved from Saga to Tokyo to achieve her goal, attending an arts-focused high school and university while also graduating from the Watanabe Entertainment School.

Fukagawa made her debut as a voice actress in 2014 and secured her first leading role in the same year, playing the character Toko Fukami in the anime television series Glasslip. This early leading role helped establish her presence in the industry. She has since built a career with a range of notable performances. One of her key roles is as Hanako Yamadagi in the 2018 television series Ongaku Shōjo (Music Girls), where she voiced the cheerful and tone-deaf protagonist who becomes involved with an idol unit. Other major roles include voicing Himeno Kimihara in Centaur's Worries (2017) and Yuu Akina in Stardust Telepath (2023). Beyond anime, Fukagawa has an extensive portfolio in video games. She is particularly recognized within the franchise The Idolmaster Cinderella Girls, where she voices the character Hinako Kita across various anime, games, and related media. Her other game credits include White Cat Project, Monster Strike, and the Taiwanese game Food Girls.

While a specific, long-standing creative partnership with a single director or studio is not prominently documented in her filmography, Fukagawa has recurring professional relationships. She frequently works alongside other voice actors in ensemble casts, as seen in projects like Music Girls and The Idolmaster franchise. Her most consistent collaboration is with her talent agency, AXL ONE, which has represented her since May 2014. A notable achievement from her early life was the Avance Cup Broadcasting Competition award, which served as a catalyst for her career. Her first leading role in Glasslip in her debut year stands as a significant early achievement, demonstrating a swift rise to a principal role. Her continued participation in a major multimedia franchise like The Idolmaster also represents a significant and ongoing contribution to the industry. In addition to her acting, Fukagawa is skilled in several areas, including hip-hop and jazz dance, which she studied for nine years, as well as playing the clarinet and painting.
