Dark skin (黒人, kokujin / 日焼け, hiyake) refers to characters with darker skin tones. This includes naturally dark-skinned characters, tanned characters (tanlines), and characters with dark skin as an artistic choice. The tag covers various ethnicities and skin tones. It's often paired with tags like 'tanlines,' 'big breasts,' and 'big ass.'

Netorare (寝取られ, NTR) is a genre tag where one partner is 'taken' by another person, typically involving infidelity or cuckolding. The term literally means 'to have one's partner stolen.' NTR is a complex genre with its own tropes: the emotional anguish of the betrayed partner, the seduction/taking of the unfaithful partner, and the voyeuristic element. The genre ranges from dark drama to fetish content. Related tags include 'cheating,' 'mind break,' and 'dark skin.' NTR is one of the most polarizing tags in doujinshi — readers either love it or actively avoid it.

Cheating (浮気, uwaki) refers to infidelity or adultery in doujinshi narratives. Unlike 'netorare' which focuses on the victim's perspective, 'cheating' can be told from any perspective. The tag covers both emotional and physical infidelity. It frequently appears alongside 'netorare,' 'milf,' and 'married woman.'
