Sole female indicates that a gallery features exactly one female character throughout the entire work. This tag is important for readers who prefer focused, intimate scenarios rather than group dynamics or harems. It doesn't imply anything about the number of male partners — a sole female gallery can feature one male partner (sole male) or multiple. The tag helps distinguish between different relationship dynamics and is commonly paired with tags like 'sole male' for one-on-one scenarios or 'multiple male' for gangbang-type content. In terms of narrative structure, sole female works often develop a single relationship or encounter in depth rather than juggling multiple characters.

Lolicon (ロリコン) refers to content featuring young or young-appearing female characters. In doujinshi context, this tag indicates the presence of petite, youthful female characters. The term originates from 'Lolita complex' and is a significant demographic category in Japanese fan-made works. Content with this tag ranges from suggestive to explicit. It frequently appears alongside tags like 'small breasts,' 'defloration,' and 'schoolgirl uniform.' The tag is distinct from 'shotacon' which features young male characters.

Big penis (巨根, kyokon) is a body-type tag indicating male characters with notably large genitalia. In doujinshi, this is often exaggerated for visual effect. The tag appears across all genres and is commonly paired with tags like 'sole female,' 'nakadashi,' and 'x-ray.'
