Description
Eriko Hara serves as the central protagonist of the story, an aspiring idol whose ultimate dream is to achieve widespread recognition and become the champion of the Formula Venus tournament, a competitive musical event that determines the future of its participants. She is a teenage girl with a distinctive appearance characterized by her long red hair and blue eyes, often styled with a ponytail.

Eriko possesses an energetic and determined personality, working tirelessly to hone her skills and advance through the ranks of the competition. She is portrayed as a genuinely kind and likable individual, well-regarded by her peers, which establishes her as a classic Nice Girl archetype. This inherent goodness is most prominently displayed through her dedication to running an orphanage, where she personally cares for the children living there. Her compassionate nature extends to her rivals; she feels genuine sympathy for a competitor who faints during a match and maintains a strong sense of honor, always shaking hands with opponents after a battle.

Eriko's deep-seated motivation to become an idol is rooted in a painful past. Her mother abandoned her twelve years prior to the main events of the story, disappearing and leaving her without a parental figure. Music became the source of inspiration that helped her recover from this traumatic abandonment, and she now strives to use her own performances to inspire others in the same way. This dream is paired with the practical reality of her responsibilities, as she runs the orphanage that likely became her home after being left behind.

In the story, Eriko is a rookie participating in the Formula Venus tournament, where her primary rival and eventual opponent in the finals is Ruka Sovagasky. Ruka is a competitor with a weak vocal constitution who can only sing for about five minutes, a limitation that becomes a crucial factor in their battles. Eriko also shares a significant bond with Miu Nureha, who is both her best friend and a fellow competitor. The two train together and must face each other in the tournament's semi-finals, a confrontation that forces Eriko to reconcile her ambition with her friendship. Eriko's coach is a pivotal figure in her life, subjecting her to a Training from Hell regimen that pushes her to her physical limits, only passing her after she collapses from exhaustion. This mentor ultimately falls victim to an unknown illness and dies just before the climactic final match, leaving Eriko to compete while emotionally shaken by the loss.

Throughout the series, Eriko's development is chronicled through flashbacks that reveal her difficult entry into the Tosano production agency, her grueling early training, and her first battle. Her abilities as an idol are demonstrated in her performances, though she is noted to have a distinct trait: her vocal cords are weak, allowing her to sing effectively for only about five minutes at a time, a condition she shares with her rival Ruka. Despite this limitation, she advances through the tournament, defeating opponents with a combination of physical stamina and honed performance skills. In the final battle against Ruka, Eriko experiences a moment reminiscent of a classic sports drama, getting knocked down but finding the motivation to continue after seemingly hearing the voice of her recently deceased coach. Although she ultimately loses the final match, placing second, she returns to the orphanage to a surprise party celebrating her achievement from her friends and found family. In the final moments, Eriko reflects on Ruka's whispered words to her to keep singing her songs, and she is last seen preparing to take the stage for another performance, suggesting her journey as an idol continues beyond the tournament's conclusion.
