OVA
Description
Hikaru Usada, a 14-year-old human girl of French-Japanese descent born August 30, 1985, lives independently on Earth as Rabi~en~Rose, her chosen stage name within the *Di Gi Charat* universe. Her parents arranged this independence to support her idol ambitions, requiring her to balance multiple part-time jobs. Transforming via dice into Rabi~en~Rose initiates a rapid costume change, revealing her signature look: a pink, white, and red bunny-themed dress, oversized white rabbit ears, a cotton tail, purple high-heeled shoes, and large dice-shaped ornaments in her rose-pink twintails. Her rose-red eyes, briefly blue in a 2007 redesign, reverted to original in 2013.

The name "Rabi~en~Rose" weaves a multilingual pun, blending the French "La Vie en Rose" (meaning a carefree, optimistic life) with "Rabi" (suggesting "rabbit") and "Rose" (reflecting her rosy outlook). This rabbit motif echoes her real surname, "Usada," derived from the Japanese "usagi" (rabbit). She strongly resists being called "Hikaru Usada," partly due to its similarity to singer Hikaru Utada. Unlike other kemonomimi characters in the franchise, she lacks an animal-based verbal tic. Her primary ability involves using her oversized ears as the "Rabbit Ears Propeller" for flight or mobility.

Outwardly competitive and bossy, Rabi~en~Rose fixates on protagonist Dejiko as her rival, often displaying attention-seeking behavior or attempting to outshine her. Beneath this antagonism, however, lies a genuine desire for friendship, occasionally revealed through subtle comedic gestures. Fundamentally, she possesses a caring and kindhearted nature.

Her journey unfolds across various media:
* In the original anime and specials, she frequents the Gamers store, self-proclaiming as its "idol," though her schemes to usurp Dejiko's popularity typically fail.
* The movie *Di Gi Charat: A Trip to the Planet* sees her accidentally stow away on Dejiko's spaceship after her rabbit ear gets trapped. She aids in thwarting the Black Gema Gema Gang and gains recognition in the celebratory ending.
* *Di Gi Charat Nyo!* depicts her attending Bōbō Junior High School, harboring a crush on Kiyoshi Omocha, and assisting at her father's "Charisma" beauty salon by distributing tissues. Later, she enrolls in "Princess School," leading a cheerleading club and interacting with her idol cousin, Akari Usada.
* She maintains her core traits and design in appearances within *Winter Garden* and *Reiwa no Di Gi Charat*.

Her family includes parents Mr. Usada and Gertrude Usada I, and cousins Akari Usada, Miyako Usada, the deceased Juri Usada, and the deceased Gertrude Usada II, along with her deceased uncle Koji Usada.
