Hikaru Usada

Acting as Dejiko's fierce rival, this competitive bunny girl seeks fame as a solo idol despite living on her own. Known by the punny moniker Rabi~en~Rose, her name reflects a carefree, rabbit-themed lifestyle. Unlike other characters in the Di Gi Charat series, she lacks a signature animal verbal tic. While she frequently picks fights with Dejiko, manga storylines reveal a deeper, comedic desire to simply be her friend, adding layers to her ambitious yet lonely personality.
