Bondage (緊縛, kinbaku) is a fetish tag covering restraint and bondage scenarios in doujinshi. This ranges from simple rope bondage to elaborate suspension scenes. The artistic treatment varies from realistic kinbaku (Japanese rope bondage) to stylized fantasy restraints. The tag covers consensual BDSM scenarios as well as non-consensual restraint (when paired with 'rape'). Related tags include 'collar,' 'handcuffs,' and 'femdom.'

Kemonomimi (獣耳, animal ears) refers to characters with animal ears (and often tails) while otherwise appearing human. This includes catgirls (nekomimi), fox girls (kitsunemimi), dog girls, and other animal-eared characters. The tag is a significant character design category in anime and manga. Related tags include 'catgirl,' 'fox girl,' and 'monster girl.'

Tentacles (触手, shokushu) is a genre tag covering tentacle monsters and their interactions with characters. This is a distinctive genre in hentai with roots in Japanese horror and fantasy art. The tentacles can range from realistic sea creatures to fantasy monsters. The genre often features non-consensual scenarios and is closely related to 'monster' and 'rape' tags.
