Town revitalization through the goddess of pregnancy

Big breasts (巨乳, kyonyu) is one of the most iconic body-type tags in doujinshi and manga. It refers to female characters with notably large, exaggerated breasts that often serve as a central visual element. Artists typically emphasize size, weight, jiggle physics, cleavage, and breast-focused activities like paizuri (titjobs) and breast play. This tag spans nearly every genre — from vanilla romance to hardcore fetish content. The artistic treatment varies widely: some artists favor realistic proportions while others push into exaggerated territory. Related body-type tags include 'huge breasts' for extreme cases, 'small breasts' for the opposite aesthetic, and 'paizuri' for breast-focused sexual acts. The tag often appears alongside 'sole female' and 'nakadashi' in heterosexual content.

X-ray (X線) is a visual technique tag where the artwork shows internal anatomy during sexual acts. This allows viewers to see internal ejaculation, penetration details, and other anatomical elements that wouldn't be visible in a normal perspective. The technique is unique to illustrated content and is a significant artistic choice. It frequently appears alongside 'nakadashi' and 'impregnation.'

Impregnation (孕ませ) is a fetish tag focused on the act of getting a character pregnant. This often involves detailed internal views (x-ray) showing ejaculation and fertilization. The tag is closely related to 'nakadashi' and 'pregnancy' but specifically focuses on the conception moment rather than the resulting pregnancy. It's a significant fetish category with its own dedicated audience.
