Designed to visually capture the iconic Kamen Rider Agito Trinity Form, this S.H.Figuarts figure presents a dynamic silhouette with sharp armor lines, layered plates, and a striking red and chrome color scheme. The Trinity form is represented with multiple textured armor surfaces, translucent red accents on the chest and forearms, and a battle-ready stance that hints at high-speed combat capability. The head sculpt features a sharp visor and a restrained mask, while interchangeable hands and optional effect parts allow fans to recreate signature poses such as punching, energy slashes, and charging silhouettes. The figure uses a solid joint system for fluid poseability, with clean paint separation to reflect the armor details and subtle weathering on metal-like components.

In the series, Kamen Rider Agito follows a protector who awakens as the Unknown threaten the city. The Agito identity represents an embodiment of many possibilities, merging powers from three distinct forms to meet escalating danger. The Trinity Form emerges as the ultimate expression of Agito’s courage, allowing him to confront especially formidable foes that threaten civilians. Throughout the arc, the rider's human host, Shouichi Tsugami, must navigate memory gaps, moral choices, and the burden of awakening new powers. The Trinity phase showcases heightened speed, raw power, and resilience, underscoring the theme of unity between human spirit and mysterious power as he defends humanity from predatory threats.
