Aki Toyosaki

In Demon Slayer: Kimetsu no Yaiba, the series animated by studio Ufotable, Toyosaki voices the Hand Demon. The antagonist role marks her involvement in a major modern adaptation and stands apart from the lead and supporting parts that established her reputation. By the time of this appearance, Toyosaki had spent well over a decade as a working voice actress, having begun her career in 2006 and reached her first major roles the following year, so the Demon Slayer credit reflects her continued presence in high-profile anime productions long after her breakthrough.

Born on October 28, 1986, Toyosaki secured her first significant voice roles in 2007 as Amuro Ninagawa in Kenko Zenrakei Suieibu Umisho and Su in Shugo Chara! Her best-known performance came as Yui Hirasawa in K-On!, for which, together with her work as Kana Nakamachi in Kanamemo, she was named Best New Actress at the 4th Seiyu Awards in 2010. The following year she earned both the Best Lead Actress and Best Personality honors at the 5th Seiyu Awards, cementing her standing among the leading voice talents of her generation.

Toyosaki's music career began in April 2009 when she performed the opening and ending themes for K-On!, the ending of which later received Animation Kobe's Best Song award. That same month she and three other voice actresses debuted as the group Sphere with the single Future Stream. Her first solo single, Love Your Life, followed in October 2009, and she has since released two albums and eleven singles that have charted within the top 20 of Oricon's weekly rankings. At the 4th Seiyu Awards she also shared the Best Musical Performance honor for the K-On! mini-album Hokago Tea Time, recorded with four other actresses.
