Seihitsu no Hassan is presented in a dramatic, ready-for-display stance that emphasizes the character's enigmatic aura. The figure features a layered, flowing costume with intricate drapery and armored accents, carefully painted to bring out chiaroscuro highlights. The base evokes an ancient temple floor, with weathered stone textures and subtle inscriptions. Each piece of fabric is sculpted to suggest movement, as if the Hassan is about to blend into the shadows. The multiple mask-like elements across the costume are rendered with precise lines and a slightly metallic sheen, enhancing the sense of mystery.

Seihitsu no Hassan embodies the legendary Hassan of the Hundred Faces, an elusive servant famed for shifting identities and silent blades. In Fate/Grand Order lore, this assassin draws strength from anonymity, changing masks as easily as moods, using deception to strike unseen. The figure captures this dual nature: serene facade and hidden menace. Through patient pose, flowing garments, and a poised blade, the character is depicted as both guardian and infiltrator, a testament to centuries of whispered legends and the destinies of masters who dare to seek protection in shadows.
