Schoolgirl uniform (セーラー服, sailor fuku / 制服, seifuku) is a costume tag that's deeply embedded in Japanese manga and doujinshi culture. It refers to the iconic Japanese school uniforms — either the sailor-style (sailor fuku) or blazer-style (seifuku). This tag is significant because school settings are a common backdrop for many genres, from romance to fantasy. The uniform itself has aesthetic appeal in illustration, and artists often use it as a visual shorthand for youth and innocence. It frequently appears alongside 'lolicon,' 'sole female,' and various school-themed parody tags.

Incest (近親相姦) refers to sexual content between family members. In doujinshi, this commonly involves siblings, parent-child relationships, or other familial pairings. The tag covers both blood-related and step-family scenarios. It's one of the most common narrative frameworks in doujinshi, often used to create dramatic tension or taboo appeal. Related tags include 'sister,' 'brother,' 'mother,' and 'father.'

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.'
