Good Smile Company's Kimetsu no Yaiba Rengoku Senjurou Nendoroid captures the iconic flame-haired swordsman in a charming chibi form. The figure stands about 100 millimeters tall, with a faithful head-to-toe silhouette that emphasizes his bold presence. The hair is sculpted in bright yellow-blonde with red tips, and the flame-pattern haori is rendered with layered paint and delicate flame decals that flow along the edges of the cloak. The eyes are designed to convey his confident, warm demeanor, and the figure includes multiple accessory parts for dynamic posing, such as interchangeable hands and facial expressions. The overall finish blends glossy highlights with subtle matte contrasts to reproduce his heroic look, while the included Nichirin Blade completes the ensemble. The design prioritizes portability and display versatility, making it a standout piece for any Kimetsu no Yaiba collection.

Rengoku Kyojuro is the Flame Hashira of the Demon Slayer Corps, a charismatic and fiercely principled swordsman whose commitment to justice inspires his fellow Demon Slayers. In the series, he mentors Tanjiro and his companions, leads with unwavering courage, and embodies the spirit of Flame Breathing, a style that channels heat, speed, and resolve into devastating blades. His warm personality and relentless sense of duty leave a lasting impression on Tanjiro, Zenitsu, and Inosuke, and his tragic sacrifice during a pivotal mission demonstrates the high cost of protecting humanity from demons. This figure evokes those themes by presenting a well-rounded portrayal that honors his role as a mentor, protector, and symbol of hope within the story.
