Designed to capture the quirky charm and eldritch elegance of Hastur from Haiyore! Nyaruko-san, this figure presents a dynamic pose that hints at her mischief and hidden power. Hastur is depicted with flowing pale hair that frames a calm, almost mischievous face, large eyes with a soft gaze, and an intricate ornament that nods to her ancient origins. Her outfit blends a ceremonial robe with mythic accoutrements: a crystalline staff, ragged-edged cloak that ripples as if blown by a cosmic wind, and subtle tentacle motifs woven into the cloak and hem. The sculpt emphasizes balance and weight, so the character reads as both poised and ready to unleash a restrained surge of power. The paintwork uses delicate skin tones, gradient shading in the hair, and sharper highlights on fabric to convey texture, depth, and the otherworldly aura surrounding Hastur.

Within the Haiyore! Nyaruko-san universe, Hastur appears as one of the elder gods who interacts with Nyaruko and friends during comic adventures that blend mythology with school-life hijinks. She exudes a calm, restrained charisma that hides a occasionally capricious and dangerous side, which results in humorous misunderstandings and occasional chaos when her plans collide with the everyday world. The character's backstory includes ancient power, cosmic knowledge, and a sense of responsibility to her own mythic lineage, yet she finds herself drawn into human-scale antics on Earth. The narrative tension arises from Hastur's desire to test boundaries, protect her followers, and navigate friendships, rivalries, and romance, all while keeping her true, formidable presence just beneath the surface. This figure tries to convey that duality through pose, expression, and texture.
