Rabichi is a pink rabbit mascot functioning as both Pair Cheer and coach for Aira Harune within the Pretty Top organization. Her core responsibilities center on guiding, training, and advising Aira to advance her growth as a Prism Star, encompassing the creation of tailored training regimens and strategic performance insights.

Physically, Rabichi possesses bright blue eyes and primarily pink fur, with paler pink accents on her arms, eye areas, chest, and feet. She displays a pink nose, white muzzle, and yellow inner-ear markings, consistently accessorized with a blue bowtie featuring a yellow-orange heart gem.

Her personality blends unwavering support for Aira with a marked enthusiasm for comedy, often weaving Aira into her joke routines. Rabichi’s speech distinctly ends sentences with the suffix "-chia."

Rabichi employs unconventional training methods that initially appear unrelated to Prism Shows yet target Aira’s specific weaknesses. For example, an exercise focused on coloring within lines refined Aira’s coordination and spatial awareness, while manzai (comedy duo) practice unexpectedly honed her timing and audience engagement during performances.

She maintains professional collaborations with fellow mascot coaches Bearchi (Rizumu Amamiya’s mentor) and Nekochi (Mion Takamine’s mentor), involving joint training efforts and occasional shared duties.

The name "Rabichi" merges "Rabbit" (ラビ) and "Cheer" (チア), highlighting her cheer mascot role. A documented trivia note reveals she shares a voice actress with another character, Kyoko Asechi, though this detail reflects production elements rather than in-universe traits.

Rabichi debuted in Episode 3 ("They're Our Coaches!? Rabichi and Bearchi"), assigned to train Aira by instructors Yamada and Mr. Penguin. While consistently involved throughout *Pretty Rhythm: Aurora Dream*, narrative emphasis on mascot characters lessens past the series' midpoint.
