This fan-made 3D character model of CR-21 from Girls' Frontline is fully rigged, weighted, and textured. The geometry consists of 75k vertices and 149k triangles with a solidify outline enabled, though the model is not completely UV mapped.

The character rig features IK/FK switching for both the limbs and spine, alongside isolated rotation toggles for the head and limbs. Secondary animation is supported with dedicated bones for the hair, chest, tail, and earrings. Facial expressions are managed through bone-driven shape keys, allowing control over eye sparkles, blushes, blinks, and various mouth poses.
