Ichika Nakano is depicted in a playful crossover look, wearing a cozy nekomimi hoodie that blends casual charm with fantasy flair. The hoodie is sculpted to show fluffy cat ears perched atop a hood that frames her face, with meticulous fur texture and subtle shading to bring depth to the orange-brown hair and warm eyes. Her pose balances a relaxed stance with a hint of motion, as if she is about to turn and offer a playful wink. The figure captures the contrast between her refined, mature personality and the cute, whimsical hoodie, while the tassels and base details hint at a lighthearted anime aesthetic. Her outfit beneath the hoodie features a simple, tasteful ensemble that nods to the character's design in the series, with clean lines and a soft color palette that compliments the fur accents. The paintwork uses gradients on the skin and hair to reflect lighting, and the eyes are designed to capture Ichika's confident but approachable expression.

Ichika Nakano is the eldest of the Nakano quintuplets and often serves as the calm, self-assured anchor of the sisters. In Gotoubun no Hanayome, she hides a playful side behind a composed exterior, using her experience and warmth to guide her sisters and to work with Futaro’s tutoring sessions. Although she projects confidence, she carries doubts about love and her future, which gradually surface as the story unfolds. Ichika's interactions are characterized by subtle humor, occasional misdirection, and moments of genuine tenderness. Her growth throughout the series reveals loyalty to her family, a fierce sense of responsibility, and a soft spot for those who earn her trust.
