Haruka made it through the audition for and was accepted into Takarazuka Music School at age 19, choosing to be among those to play male roles after having finished the first year of her education. Directly after graduation she played important (but not leading) otokoyaku roles in the Moon Troupe and quickly gained great popularity in the fandom. When the Moon Troupe decided to do a performance of For Whom the Bell Tolls, Haruka was given the role of Robert Jordan and her former class-mate Kaioh Michiru (new-comer in the Moon Troupe after having initially performed in Snow Troupe) was given the role of Maria. The show became a gigantic success and made Haruka one of the most famous and loved otokoyaku actresses. She and Michiru were declaired the new golden combi of Takarazuka and as a result allowed to become the star performers and heads of the new troupe, the Rose Troupe. The opening performance of this troupe was an abstract staging of Aida which ended up a tremendous success also outside the Takarazuka fandom and now when Haruka finds herself in Moonlocket, she and Michiru have been working hard on the preparations for an original stage project.


Haruka hadn't always wanted to become an otokoyaku. From she started racing at age 14 and until her brother, Haruki, died when she was 17, her biggest dream was to become a F1 racer. However, due to an accident at the circuit, her three-year-older brother who also raced was killed when he lost control over his car and from that moment Haruka decided that it wasn't her dream to pursue and instead started focusing her talents on music and dance (both interests she'd had since she was a girl, having played the piano since she was four and danced ballroom since she was ten). It wasn't until her 19th birthday, however, that she decided what to make of these interests, when a girlfriend of hers took her to a Takarazuka performance of Elisabeth. Haruka was struck by the freedom that the otokoyaku actresses experienced on stage, how they were no longer bound by the gender roles of the Japanese society, and decided to join their ranks. When the annual auditions were hosted barely half a year later she attended and was accepted into the Takarazuka School of Music.
