The Core Cast: Who’s Who in Oshi no Ko’s Universe

1. Haruki Setsuna – The Reluctant Idol and Rising Star

Key Insights

Haruki Setsuna embodies the multifaceted journey of modern idol culture. At first appearing as a talented but timid singer, Setsuna evolves into a complex protagonist torn between dreams and reality. Her internal conflict—balancing honesty with public image—made her a fan favorite early on. Her gradual character development, from hesitant novice to assertive leader in PLG (Pro Big Girl), symbolizes resilience and authenticity. Fans admire her vulnerability and growth, especially as she confronts jealousy, betrayal, and personal loss.

2. Megumi Tachibana – The Charismatic Oversoul

Megumi Tachibana is the shining idol everyone desires—and few can claim. Known for her stunning looks, magnetic stage presence, and ambiguous allure, Megumi represents the glamour and mystery of stardom. But beneath her perfect facade lies emotional turmoil and trauma. Her complicated relationship with Haruki fuels much of the narrative, highlighting themes of trust, control, and healing. Megumi’s layered portrayal—equal parts vulnerable and powerful—cements her role as one of anime’s most fascinating idol protagonists.

3. Yuun Kubota – The Ruthless Media Savior

Yuun Kubota stands in stark contrast to idol ideals—sharp, strategic, and driven by ambition. As a powerful media manager, Yuun understands image and influence better than anyone. His morally gray methods and intense loyalty to PLG’s success make him both a vital ally and a source of tension. Fans are drawn to his charisma and intelligence, even as his actions challenge ethical boundaries. Yuun’s character embodies the darker side of fame and ambition.
