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.

Rape (レイプ) is a content tag indicating non-consensual sexual activity. In doujinshi, this ranges from forceful scenes to fantasy scenarios. The tag is used for content where sexual acts occur without consent from one or more participants. It's important to distinguish this as a fictional content tag — all characters are depicted as adults in the artistic context. The tag frequently appears in darker genres and is often paired with tags like 'bondage,' 'mind break,' and 'dark skin.'

Muscle (筋肉, kinniku) refers to characters with muscular physiques. This tag covers both male and female characters with visible muscle definition. In doujinshi, this ranges from subtle athletic builds to heavily muscled bodybuilder types. The tag has grown in popularity alongside the 'gijinka' and fitness trends in fan art.
