Aoi Koga

In "Demon Slayer: Kimetsu no Yaiba," the Ufotable production, Koga voices Rokuta Kamado, the youngest of protagonist Tanjiro's siblings. The role is one entry in a career that took off in the late 2010s, after Koga had spent her early years drawn toward voice acting and finally entered the profession in 2014. She landed her first leading part in 2017 as Sora Kaneshiro in Angel's 3Piece!, a series whose main cast also formed the musical group Baby's Breath, of which Koga was a member. Affiliated with the agency 81 Produce, she hails from Saga Prefecture and was born on August 24, 1993.

Koga has voiced a wide range of leading characters across television anime. Her signature roles include Kaguya Shinomiya in Kaguya-sama: Love Is War and Shouko Komi in Komi Can't Communicate, both adaptations in which she headlined the cast. Earlier credits include Yuri Ashida and Juli Liszt in Aikatsu Stars! and Yuri Miyata in Two Car. She has also played Ange le Carré in Princess Principal: Crown Handler and Princess Ellee, also known as Cure Majesty, in Hirogaru Sky! Precure. Beyond animation, Koga made a cameo appearance in the live-action film adaptation of Kaguya-sama: Love Is War.

Koga's performances have earned her several industry honors, most notably the prize for Best Actress in a Leading Role at the 14th Seiyu Awards, one of the most prominent accolades in Japanese voice acting. Her work outside straightforward voice roles has included singing as part of Baby's Breath and her on-screen cameo in the Kaguya-sama live-action feature, reflecting a career that extends beyond the recording booth.
