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.

Blowjob (フェラチオ, fellatio) is one of the most common sexual act tags in doujinshi. It covers oral sex performed on male characters. The artistic depiction varies from realistic to stylized, with many artists developing signature techniques for depicting the act. Common visual elements include drool, tongue detail, eye contact, and depth indicators. The tag appears across virtually all genres and is frequently paired with tags like 'ahegao,' 'big breasts,' and 'sole female.'

Mind control (マインドコントロール) is a genre tag where characters are mentally manipulated or controlled. This ranges from hypnosis to magical control to technological mind alteration. The genre is distinct from 'rape' as the controlled character may appear willing. Related tags include 'mind break,' 'rape,' and 'drugs.'
