(C56) [Forbidden City (Kikusui)] Sword Dancer (Jubei-chan, Hikaru no Go)

Yaoi (やおい) refers to male-male romantic or sexual content created primarily for a female audience. In doujinshi, yaoi works feature relationships between male characters and span a wide range from soft romance to explicit content. The genre has its own rich ecosystem of tropes, character dynamics, and artistic conventions. Yaoi is distinct from 'bara,' which is male-male content created by and for gay men. Common related tags include 'males only,' 'seme,' 'uke,' and 'anal.'

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.'

Collar (首輪, kubiwa) is a costume/accessory tag indicating characters wearing collars, often in a BDSM context. Collars symbolize ownership or submission in kink scenarios. The tag covers both decorative collars and functional bondage collars. It frequently appears alongside 'bondage,' 'femdom,' and 'pet play.'
