Wakana Gojo is an introverted high school student who has dedicated his life to mastering the traditional art of crafting Hina doll heads under the guidance of his master-craftsman grandfather. He possesses exceptional technical skills in human anatomy scaling, traditional garment drafting, complex textile stitching, and pattern engineering, allowing him to adapt rigid doll-making methods into full-scale human costumes. Due to childhood trauma from a peer who harshly criticized his hobby, he suffers from profound social isolation and performance anxiety, causing him to hide his talents from the world. Functionally, he serves as the team's chief structural engineer, tailor, and material coordinator, physically fabricating complex, high-fidelity prototypes completely from scratch.

Marin Kitagawa is a highly visible, trend-setting high school student who proudly embodies modern Japanese "gyaru" fashion through her bold personal aesthetics and charismatic personality. She possesses an encyclopaedic knowledge of niche subcultural media, ranging from tactical role-playing games to magical girl anime, and is driven by an intense respect for character designs that demands absolute physical accuracy in her projects. She features exceptional interpersonal charisma, actively dismantling social cliques and enforcing a zero-tolerance stance against subcultural gatekeeping or judgment. In the design workflow, she operates as the creative director, performance model, conceptual planner, and primary financial investor for all costume fabrications.

Sajuna Inui (Juju) is a highly respected, independent digital presence in the costuming community who maintains strict, studio-grade standards for her flawless adaptations of magical girl source materials. She leverages a naturally petite, compact frame to precisely mirror the body proportions of younger fictional characters, prioritizing premium material sourcing and highly controlled indoor environments for her photography. She possesses a fiercely passionate, no-nonsense attitude toward her craft, refusing to compromise on quality or chase fleeting social media trends. Within the collective, she functions as a critical technical analyst who provides objective, unvarnished performance critiques on garment construction and structural integrity.

Shinju Inui is Sajuna’s younger sister who specializes entirely in behind-the-scenes production mechanics, demonstrating advanced proficiency with professional DSLR cameras, lighting rigs, and digital post-processing software. Despite being the younger sibling, she features a tall, robust, and highly developed physique that stands in direct structural contrast to her sister's frame. She initially suppresses a private technical interest in crossplay due to severe body-image anxiety before gaining the confidence to transition into active performance modeling. Functionally, she operates as the principal documentarian, camera operator, lighting technician, and male-character costumer within the circle.

Kaoru Gojo is a recognized master craftsman operating within the historical Saitama doll-making tradition, managing a fully functional home workshop where he raises and trains his grandson. He employs a patient, non-intrusive pedagogical approach, requiring student artisans to learn through iterative practice and error correction while maintaining a progressive view that validates modern subcultural costume design as legitimate technical training. Despite managing intermittent, age-related health setbacks that require him to balance his commercial workload with physical rest, he remains a steady anchor for the household. He provides foundational historical knowledge, advanced workshop machinery access, and essential stability to the manufacturing environment.

Amane Himeno is a highly respected veteran of the costuming community who specializes exclusively in high-fidelity crossplay, utilizing advanced expertise in heavy facial contouring, structural wig architecture, and temporary body-shape alteration methods to achieve male character transformations. He serves as an invaluable external industry consultant, delivering advanced workshops on cosmetic application and wig-styling mechanics to less experienced creators. Additionally, he provides vital operational knowledge concerning convention event safety, venue mapping, thermal regulation, and long-wear physical comfort. His functional role centers on guiding new tailors through the practical, real-world logistics of displaying complex outfits in crowded public spaces.
