Ichika Nakano, the eldest of five identical sisters, embodies responsibility and care, often adopting a maternal role within her family. She sports short hair with a distinctive long strand on her right side and wears a signature earring denoting her firstborn status, paired with a notably curvaceous figure. Juggling academic rigor and an emerging acting career, she diligently studies between film shoots, driven to establish herself professionally before celebrating her successes with her siblings. Initially dismissive of her sisters’ academic potential, she transforms into a motivated student after Futaro Uesugi, their tutor, sparks her determination. This change mirrors her inner conflict between pursuing her ambitions and preserving family unity. Her relationship with Futaro oscillates between playful teasing and vulnerable sincerity, evident in blushing reactions to romantic tension. A pivotal moment arises when she impulsively kisses him during the school festival, exposing her turmoil over balancing her feelings with her sisters’ affection for him. Skilled in mimicry, she replicates her sisters’ mannerisms—though less seamlessly than Miku—leveraging her sharp insight into human behavior. This talent sometimes fuels friction, especially when her career goals collide with her siblings’ desires. Behind her poised exterior lies insecurity about her familial role and fear of disrupting their bonds, leading her to suppress open rivalry for Futaro’s attention despite private jealousy. Five years post the central events, Ichika emerges as a successful actress, fulfilling her lifelong dream through relentless perseverance. Her arc traces self-discovery and the reconciliation of personal ambition with family loyalty. Key moments—such as crediting Futaro for reigniting her academic drive and embracing her sisters’ divergent journeys—underscore her growth, cementing her evolution from a guarded eldest sibling to a self-assured individual navigating love, ambition, and kinship.
