Whisper☆Angel Sasayaki stands in a graceful, serene pose that captures a moment of hushed enchantment. The figure wears a delicately sculpted outfit with soft, flowing lines and a light, pearlescent finish that catches the light with every angle. Her long hair cascades in graceful waves, with tiny ribbons and subtle gradient shading that suggests motion. She features slender fingers posed near her lips in a whispered greeting, and faint, translucent wings or wing-like accents fan behind her, adding an ethereal scale to the silhouette. The base is clear and softly faceted, elevating the character while keeping the focus on the figure's gentle presence. Details such as lace, frills, and tiny accessories emphasize craft and care.

In Utau, Whisper☆Angel Sasayaki is a guardian of quiet moments, a traveler between songs who gathers memories from dawn to dusk and threads them into lullabies that soothe turbulent hearts. Born of a moonlit melody, she wanders city rooftops, tranquil gardens, and crowded stations, listening for the whispers of those who need courage more than applause. Her mission is to spark confidence with a single soft note, guiding friends and strangers through trials until dawn reveals a brighter chorus. She bears a quiet resolve: every whisper carries a choice, and she will always choose hope over fear, even when the path is unclear.
