Born as the eldest of the Nakano quintuplets, Ichika naturally assumed a leadership role within her family, acting as the big sister who looks after her younger siblings. Unlike her sisters, she pursues a professional career early on, aiming to become a successful actress while still managing her studies.

Despite her initial indifference toward academics, Ichika joins Futaro’s tutoring sessions with her sisters. As she spends more time with him, her admiration for his determination grows, leading to conflicted feelings of love. However, her pursuit of romance causes tensions with her sisters, forcing her to confront her desires and responsibilities.

Ichika has short, pale blonde hair that reaches just above her shoulders, with long side bangs framing her face. She has light purple eyes and a beauty mark under her left eye, making her distinct among her sisters.

Her casual style is mature and fashionable, often consisting of off-shoulder tops, skirts, and stylish accessories. She prefers a laid-back and elegant aesthetic, reflecting her cool and confident persona.

In contrast, her school uniform consists of a green blazer, a white blouse, and a pleated skirt, like her sisters.

Ichika is charming, playful, and easygoing, often teasing her sisters and acting flirtatiously toward Futaro. She presents herself as mature and responsible, but underneath her composed demeanor, she harbors insecurities and doubts about her choices.

  Ichika is the first among the sisters to pursue a career, balancing her school life with acting auditions. However, her developing feelings for Futaro cause conflict, as she struggles to choose between love and her professional aspirations. As tensions rise, Ichika attempts to sabotage her sisters’ chances with Futaro, disguising herself as Miku to manipulate his perception. This creates strain among the quintuplets, leading to a turning point in her character arc.

• Redemption and Moving Forward
  After realizing her mistakes, Ichika chooses to prioritize her career over romance, ultimately letting go of her pursuit of Futaro.
