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.

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.'

Twintails (ツインテール) is a hairstyle tag referring to hair tied in two pigtails. This is a popular character design element in anime and manga, often associated with tsundere or energetic characters. The hairstyle has a dedicated following and is used as an aesthetic preference filter. Related hairstyle tags include 'ponytail,' 'short hair,' and 'long hair.'
