The Haruka seiyuu (voice actor) cast includes some of the best and most popular in the anime industry. All of them are well loved by their fans, and many of them have been known and adored for years under other roles in the industry.

With the live stage version of Maihitoyo came a live-action cast for the the Haruka characters. The live stage version was so successful that it continued with a second, "original" Haruka1-based story, Oborosoushi （朧草紙）.
