Hiroi Kikuri is rendered as a compact chibi-style figure designed for desktop display. The character's hair is sculpted in flowing strands with soft curls and painted with gentle shading to bring out the lilac hues and pink tips that fans will recognize from the Bocchi the Rock! series. She wears her signature scene-inspired outfit translated into a dollable, collectible form: a crisp sailor-style top, a pleated skirt, and subtle band details that echo her role as guitarist. The base uses a crystal-clear stand and a decorative platform that evokes a small stage diorama. The finish is glossy with careful line work to highlight her eyes and accessories, making the figure feel lively and ready to decorate a desk or shelf.

Hiroi Kikuri is introduced as the cheerful, ever-optimistic guitarist and the spark that keeps Bocchi's band energy alive. In the series, she jokingly lends her friends a push when doubt creeps in, offering practical advice and encouraging performances with a never-fading sense of humor. Kikuri's musical dream anchors many episodes, as she and the rest of the group navigate first gigs, creative blocks, and the awkward charm of growing up while chasing a shared stage. Her friendship with Bocchi, Nijika, and other members demonstrates themes of resilience, collaboration, and the joy of turning passion into friendship, even when stage fright looms.
