(C94) [Perestroika (Inoue Kiyoshirou)] BBXChannel (Fate/Grand Order)

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.

Stockings (ストッキング) is a highly popular fetish tag focusing on thigh-high stockings, pantyhose, and similar legwear. This tag has a dedicated following due to the aesthetic appeal of stockings in illustration — artists often use them to accentuate leg lines, create contrast with skin, and add visual texture. The tag covers various styles including thigh-highs, garter stockings, pantyhose, and knee-highs. It appears across all genres and is often paired with 'sole female,' 'big breasts,' and 'schoolgirl uniform.' Some artists are known specifically for their detailed stocking artwork.

Sex toys (オナホール, バイブ) is a fetish tag covering the use of various adult toys in doujinshi. This includes vibrators, dildos, fleshlights, and other devices. The tag covers both solo use and use during partnered scenes. Artists often use toys to add variety to scenes or to depict specific fetish scenarios. Related tags include 'masturbation,' 'dildo,' and 'vibrator.'
