The change in social concepts has cleared the way for the popularization of the
alien sex doll. When a prestigious journal published a study on "simulated partners improving autism tendencies", purchase orders from medical institutions increased threefold. This destigmatization process allows manufacturers to focus on functional optimization rather than moral defense, and the proportion of R&D funds used for compliance review has dropped from 28% to 9%. In contrast, the
hentai sex doll has benefited from the globalization of two-dimensional culture, and pre-sales of limited edition products at anime exhibitions often sell out within one minute. Both types of products are reducing the hidden costs of marketing by constructing legitimacy narratives.
