This S.H.Figuarts Kamen Rider Knuckle Kurumi Arms figure captures the distinct walnut-themed armor and rugged brawler silhouette seen in Kamen Rider Gaim. Sculpted details emphasize the knuckle-style gauntlet, layered armor plates, and seed motif decorations across the chest and limbs. The paintwork combines metallic and matte finishes to highlight mechanical textures and organic Kurumi (walnut) motifs, while sculpted articulation points remain mostly concealed within the design for smooth posing. The figure stands approximately 140 mm tall and features multiple points of articulation typical of the Figuarts line, allowing dynamic fighting stances. Typical accompaniments include exchangeable hands, a Kurumi Lockseed accessory, and effect or display parts to recreate signature attacks and action poses with stable posing and balanced weight distribution.

Kamen Rider Knuckle is presented as a tough, streetwise combatant within the Kamen Rider Gaim universe who relies on close-quarters strength and a tenacious fighting style. Using the Kurumi Arms, he taps into a walnut-themed power set that enhances striking capability and defensive resilience, turning his gauntlet and armor into his primary weapons in clashes over Lockseeds and territorial disputes. Throughout the storyline he is driven by loyalty and a straightforward sense of honor, often acting as a protector of his allies and willing to charge into conflict when necessary. His narrative arc explores the pressures of factional rivalries, the moral complexity of power, and personal growth as he confronts stronger opponents and questions about how to use force responsibly. Relationships with other Riders and shifting alliances highlight his pragmatic approach: he can be an ally one moment and a relentless rival the next, reflecting the chaotic world around him and his hard-edged determination to survive and stand up for those he cares about.
