Phosphophyllite stands in a poised, subtly dynamic pose, its slender silhouette captured in a glossy translucent PVC finish that catches light from multiple angles. The figure features a pale mint green skin tone with delicate crystal facets along the shoulders, arms and legs, giving the impression of a living gemstone. The face has large glassy eyes and a calm, introspective expression, with carefully painted pupils and soft shading. Hair is sculpted in layered crystalline strands that frame the head and trail down the back. Throughout the model there are tiny glittering highlights and subtle color gradients ranging from icy blue to pale jade. The outfit resembles a suit of faceted armor with seamless transitions between parts, and the base evokes a crystalline terrain that suggests the figure is carved from moonlight itself. The overall finish emphasizes fragility and resilience in equal measure, conveying the character's ethereal presence and inner strength.

Phosphophyllite, commonly known as Phos, is one of the gems who inhabit the lunar court in Houseki no Kuni. Born as one of the most fragile and useful gems, Phos carries a longing to find a purpose beyond tasks assigned for survival. The journey follows their evolution from a beginner tasked with compiling an encyclopedia to a catalyst for change through encounters with other gems, dangerous battles, and unexpected transformations. As Phos faces loss, memory, and changing form, their approach to life shifts from caution to bold experimentation. Through perseverance, curiosity, and an unusual blend of vulnerability and will, Phos learns that identity can be shaped by experiences, friendships, and the choices they make in the face of adversity.
