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.

Bondage (緊縛, kinbaku) is a fetish tag covering restraint and bondage scenarios in doujinshi. This ranges from simple rope bondage to elaborate suspension scenes. The artistic treatment varies from realistic kinbaku (Japanese rope bondage) to stylized fantasy restraints. The tag covers consensual BDSM scenarios as well as non-consensual restraint (when paired with 'rape'). Related tags include 'collar,' 'handcuffs,' and 'femdom.'

Bikini (ビキニ) is a costume tag specifically for two-piece swimwear. This is more specific than 'swimsuit' which covers all swimwear types. The tag covers various bikini styles including string bikinis, micro bikinis, and sport bikinis. It frequently appears alongside 'big breasts,' 'dark skin,' and 'beach.'
