Shishiou Tsukasa is captured in a compact Figuarts mini form, standing in a dynamic, ready-for-action pose. The figure showcases bold red armor with black accents, a sculpted belt, and crisp paint lines that highlight Tsukasa's stern expression and iconic amethyst eyes. The hair is sculpted to convey movement, with angular bangs and a swept style that reads with his ruthless resolve. Polished surfaces mix with subtle matte finishes across the armor plates to catch light from multiple angles, while the small joints allow just enough poseability without sacrificing stability. The 90 mm scale preserves an imposing silhouette for display, making this compact unit feel energetic and authoritative, true to the character from Dr. Stone.

Tsukasa Shishiou is introduced as the powerful, uncompromising force at the center of Dr. Stone's early conflict. He argues for a world rebuilt by strength rather than science, seeking to restore a social order based on martial ideals. His plot centers on thwarting Senku's revival of civilization, opposing technology, and assembling a rival community led by his own values. Throughout the series, his charisma and strategic mind challenge the protagonists, while his personal code of honor tests his loyalties and decisions. The character's arc explores themes of power, tradition, and what it means to build a future—whether through brute force, steadfast conviction, or a surprising openness to other truths.
