OVA
Description
Hibiki Ganaha debuted as a rival idol under 961 Production in THE IDOLM@STER SP before transferring to 765 Production during THE IDOLM@STER 2's "second vision" storyline. Her most recent appearance is in THE IDOLM@STER STARLIT SEASON. She is 16 years old, born October 10, standing 152 cm tall, weighing 41 kg, with blood type A and measurements of 83-56-80. Her image color is light blue or turquoise.

Originating from Okinawa, her background accounts for her tanned skin and Okinawan dialect, incorporating phrases like "Haisai" and "Nankurunaisa" that occasionally puzzle others. She relocated alone to pursue idol work, motivated by a conflict with her older brother and the goal of supporting him financially through her success. Her family includes her mother and this brother, whose demeanor resembles the Producer. This connection shapes her dynamic with the Producer, whom she treats as a substitute sibling through playful arguments that conceal mutual affection.

Hibiki radiates high energy, optimism, and friendliness, nearly matching Yayoi Takatsuki's exuberance. While fiercely competitive in rivalries, she instinctively seeks friendships. Her dance skills rank highest among 765 Production idols in games like THE IDOLM@STER: One For All. Despite her confidence, she self-identifies as a crybaby, tearing up easily in dramatic or comedic moments, such as losing pets or during anime scenes.

She owns numerous pets—a hamster (Hamuzō), dog (Inumi), cat, rabbit, parrot, pig, flying squirrel, and crocodile—and frequently misplaces them, requiring help from idols like the Futami twins to recover them. Her bond with animals extends to co-hosting the TV show "Break Out Animal World" with Inumi. Academically, she displays unexpected intelligence by tutoring the Futami twins in THE IDOLM@STER SHINY FESTA: Funky Note.

Her hobbies include knitting, table tennis, walking, cooking Okinawan dishes like chanpurū and sōmin tāshiya, and housework. Sensitive to heat, she prefers indoor activities and once led her Okinawan table tennis club. In THE IDOLM@STER SHINY FESTA, she performs in rhythm concerts for the Funky Note/Rhythmic Record version alongside Yayoi Takatsuki, Iori Minase, and the Futami twins.

Trivia notes her dislike of cute/girly outfits despite her "Cute" attribute in spin-offs like Cinderella Girls. Early concept art featured thick eyebrows, and she shares a birthday with Noriko Shiina. Her name combines 響 ("sound/echo") for Hibiki and 我 ("I/self"), 那 ("what?"), and 覇 ("supremacy") for Ganaha.
