Isshiki Iroha stands poised in Serenus Couture style for a 10th Anniversary edition. The figure captures a refined balance between elegance and charm: a floor-length, tiered dress with intricate lace textures, metallic embroidery, and a cobalt-blue cape that drapes behind her. Her hair is arranged in sweeping strands with delicate accessories and a subtle tiara. She holds a small accessory, like a quill or fan, that nods to her witty persona. The sculpt emphasizes graceful lines, a slender waist, and a confident pose with one hand extended as if inviting conversation. The base features a stylish monochrome platform with light accents that echo the outfit's color palette.

Isshiki Iroha is a perceptive, energetic character who navigates the social currents of her high school life with tact and charm. In Yahari Ore no Seishun Love Comedy wa Machigatteiru, she frequently challenges conventional reputations, seeks to help friends with practical solutions, and uses her wit to diffuse tense moments. Her arc revolves around balancing personal ambitions with genuine care for the people around her, building relationships through conversation, persuasion, and collaboration with the Service Club. Through trials and misunderstandings, she grows in self-awareness, loyalty, and leadership, while keeping a playful, optimistic spirit that makes her a memorable ally in the story.
