Hikari Kagura, a second-year student in Seisho Music Academy’s Actor Training Department (99th Graduating Class), forged an unbreakable childhood bond with Karen Aijo in Japan. Their shared dream of performing in *Starlight* after witnessing the play propelled Hikari to train for 12 years at England’s Royal Academy of Theatrical Actors. There, she mastered classical ballet, jazz dance, and vocal music, sustaining her connection to Karen through handwritten letters. Her sterling record in revue auditions abroad shattered when a crushing defeat by rival Judy Knightley extinguished her passion. Reduced to mechanical routine, she drifted until a botched performance reignited memories of her vow to Karen. This spurred her return to Seisho’s revues, driven by flickering resolve to reclaim her brilliance. Hikari’s striking cerulean eyes and long black hair—framed by blunt bangs—are accentuated by a twin-star hairpin, Karen’s childhood gift. Her wardrobe shifts between Seisho’s gray uniform, a breezy white sundress with azure accents, and a revue ensemble: a navy-blue jacket edged in gold, a jeweled diadem, and a rope dagger. A jellyfish plush, Mr. White, clings to her as a constant companion, echoing her marine-life fascination. Once ambitious and outgoing, Hikari’s demeanor cooled post-defeat, leaving her aloof yet fiercely protective of Karen, Mahiru Tsuyuzaki, theater, and jellyfish. Rare glimpses of vulnerability surface around Karen, while her rocky dynamic with Mahiru matures into a partnership tested in collaborative trials, documented in spin-off tales. Within Seisho’s giraffe-judged revues, Hikari battles to resurrect her faded spark and honor her promise. Her clashes with Karen crescendo in *Rondo Rondo Rondo*, viewed through Nana Daiba’s lens, where Hikari confronts the futility of recreating ephemeral stages. The *Epic of Bravery* stage play reimagines her as a hero shielding Karen from existential threats, mirroring her internal struggle: fearing irrelevance in tranquility yet yearning to carve fresh destinies. Her tastes favor jellyfish motifs, rich chocolate, and Sanuki udon, while wobbly desserts like pudding and administrative chores repel her. Academic accolades—lead roles in *Romeo and Juliet* and *Othello*—further cement her theatrical legacy beyond the revues’ glare.
