Omi Harune serves as the nurturing core of the Harune family, her life shaped by dual legacies of artistic flair and domestic devotion. Once a sought-after Prism Star stylist, she crafted iconic looks for legendary performer Sonata Amamiya, forging a deep connection with Sonata’s family. Before each performance, Omi would steady Sonata with a hand on her back and the whispered mantra, "The sparkle of the Prism is always right here"—a ritual blending practicality with symbolism to bolster her friend’s resolve.

Her marriage to Hiroshi Harune shifted her trajectory, trading glittering stages for flour-dusted aprons as co-owner of Haru no Oto bakery. Between kneading dough and raising four children—Aira, Itsuki, Eru, and Uru—she channels her creative instincts into "Pretty Remake" sewing projects, transforming Hiroshi’s thrifted finds into vibrant outfits that let her children’s personalities shine.

Hiroshi’s insistence on burying her Prism Show past, rooted in Sonata’s career-damaging Aurora Rising accident, never extinguished Omi’s quiet understanding of Aira’s stage dreams. When Hiroshi banned Aira from Prism Shows, Omi navigated the tension with calibrated care, urging Aira to respectfully challenge restrictions while preserving family bonds.

Kyoko Asechi’s push for Aira to attempt the Aurora Rising reignited Omi’s old fears, her resistance crumbling only after Hiroshi acknowledged their daughter’s distinct path. This evolution culminates in Omi stepping back into the spotlight’s periphery at the Prism Queen Cup, joining Aira mid-performance as both anchor and ally.

Warmth and resolve define her approach to motherhood, tempering Hiroshi’s caution with measured support for her children’s self-determination. Her laughter-filled kitchen and deftly mended garments mask a steel core, one that guards her family’s cohesion without stifling their individual sparks.
