Ventricosus is rendered as a luminous gemstone figure inspired by Houseki no Kuni. The bust and limbs are sculpted with meticulously faceted surfaces that catch light from every angle, creating a prism of subtle blues, greens, and pale lilac hues. The figure wears a flowing cloak-like element that mimics sea-glass textures, accented by frosted edges and delicate jewelry-like banding around the arms and neck. The base is minimal yet elegant, designed to suggest an arctic sea rock. The eyes are inlaid with clear gems that glow softly, giving a serene, contemplative presence even in display.

Ventricosus, within the Houseki no Kuni universe, is depicted as a thoughtful guardian gem who tends toward quiet diplomacy rather than overt confrontation. Their history suggests a role as mediator among rival factions of gemstones, using wit and restraint to prevent cycles of violence. In times of crisis, Ventricosus draws on an inner well of resilience, turning light refracts into protective shields and guiding others toward safer paths. Though not the loudest warrior, their steadfast demeanor and crystalline calm influence decision-making, helping their fellow gems navigate the treacherous landscapes of the lunar world.
