Here, we report embedded three\u2010dimensional bubble\u2010like polar textures in the van der Waals ferroionic crystal CuInP\n                    <jats:sub>2<\/jats:sub>\n                    S\n                    <jats:sub>6<\/jats:sub>\n                    (CIPS). By combining angle\u2010resolved vector piezoresponse force microscopy, tomographic piezoresponse force microscopy, and transmission electron microscopy, we reveal that these polar textures are isolated, capsule\u2010shaped polar nanostructures volumetrically embedded within the CIPS lattice rather than surface\u2010localized features. The angle\u2010dependent piezoresponse is consistent with a center\u2010divergent N\u00e9el\u2010like polarization configuration, while cross\u2010sectional microscopy indicates local site\u2010selective Cu\u2010ion occupancy within the embedded textures, providing a plausible structural basis for ionic\u2010ordering\u2010assisted stabilization. Distinct from interface\u2010constrained polar textures in conventional oxide heterostructures, these bubble\u2010like textures exhibit only weak size variation over a broad thickness range, suggesting an intrinsically stabilized, ionic\u2010ordering\u2010related origin. Furthermore, they can be reversibly reconfigured between bubble\u2010like and quasi\u2010single\u2010domain states under moderate electric bias, plausibly through local Cu\u2010ion redistribution. These findings highlight ionic ordering as a promising route for stabilizing and manipulating embedded 3D polar textures in van der Waals ferroics and suggest opportunities for electrically reconfigurable nanoscale ferroic devices.\n
