Yua Nagae is a Japanese voice actor born on November 30, 1994, in Ehime Prefecture, Japan. She began her career in the entertainment industry in 2016, initially affiliated with the talent agency Quatrestella. Her debut role was as Yukidaruma in the game "Tsukumo Hime" that same year.

Nagae's career saw a series of transitions in its early years. In October 2017, she left Quatrestella and joined BloomZ shortly after. During her time at this agency, she began appearing on BS Fuji programs in April 2018 and subsequently formed the voice actor unit Guildrops with fellow voice actors Marina Yamada, Yurie Kosakai, and Yuri Ehara. The group was active until 2024.

Her first major television anime role came in October 2018 when she was cast as Haruna Kanzaka in the series "My Sister, My Writer". This role is widely considered her representative performance. She also voiced the character Sakura in "Comet Freyline: Prologue" and the role of Ocea in "Seaside-sō no Aquakko".

In February 2020, Nagae changed agencies once more, moving to Office Anemone. Concurrent with this move, she changed the presentation of her stage name from the kanji 永恵由彩 to the hiragana ながえゆあ, though the pronunciation remained the same. Beyond her work in television animation, Nagae has built an extensive portfolio of roles in video games, including characters in major titles such as "Ys IX: Monstrum Nox," "The Legend of Heroes: Trails through Daybreak," and "闪乱忍忍忍者大战海王星 -少女们的响艳-". Her work also extends to OVAs, drama CDs, theatrical performances, and narration work.

Nagae is known for her interests in drawing and cosplay, and she lists illustration and traditional poetry chanting as her special skills. Her associated voice actors often cited include Marina Yamada, Yurie Kosakai, and Yuri Ehara, her former colleagues in the unit Guildrops.
