Rin Setsu A is brought to life with striking attention to detail: the sculpted armor, flowing robes, and the distinctive lacquered elements catch the light to reveal a battle-worn texture. The figure features a dynamic pose suggestive of swift movement, with one leg forward and a hand gripping a weapon ready to strike. Fine paintwork emphasizes layered fabrics, intricate patterning along the trim, and metallic accents on armor plates. Subtle weathering effects and precise facial expression convey steadiness, resolve, and an air of mystique characteristic of Thunderbolt Fantasy's puppet design.

Within the Thunderbolt Fantasy Tourikenyuuki saga, Rin Setsu A moves as a disciplined swordsman whose blade speaks for the silent oath he keeps. Born of shadowed trade winds and forged alliances, he seeks balance between duty and personal fate, often finding himself at the center of conflicts that threaten both the living and the puppets who walk between worlds. His journey pits him against rival puppeteers and malevolent spirits tethered to the dragon sword, forcing him to choose between mercy and necessity. Along the way he learns about courage, sacrifice, and the fragile line between legend and memory, shaping him into a figure both feared and revered.
