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.

Swimsuit (水着, mizugi) is a costume tag covering various swimwear including bikinis, one-pieces, school swimsuits (スクール水着), and micro bikinis.
