Anal intercourse is a common sexual act tag in doujinshi. It appears across nearly all genres and demographics, from vanilla romance to extreme fetish content. The artistic depiction ranges from realistic anatomy to highly stylized presentations. This tag frequently co-occurs with tags like 'nakadashi' (internal ejaculation), 'big breasts,' and various body-type tags. Some artists specialize in anal content, developing signature techniques for depicting the act. The tag covers both consensual and non-consensual scenarios depending on accompanying tags.

Futanari (ふたなり) refers to characters with both male and female sexual characteristics — typically female-presenting characters with a penis. This is a significant genre in hentai with its own dedicated audience. The tag covers a wide range from characters with both sets of genitalia to characters who are essentially female with male genitalia. Artistic treatment varies from realistic to highly stylized. Related tags include 'males only' (for futanari-only content) and 'yuri.'

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.'
