平野綾
The popularity of the series made Aya Hirano one of the earliest examples of the "idol voice actor" crossover in the late 2000s. Haruhi, Yuki, and Mikuru (voiced by Aya Hirano, Minori Chihara, and Yūko Gotō), along with Japanese drama actor Toma Ikuta, made their first Japanese ad appearance in promoting Lotte Acuo Gum in March 2010.
