[Arinotowatari (Arinotowatari)] Seijun Kouhai ga Shokuba no Zenin to Neteta Hanashi (Fate/Grand Order)

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.

Double penetration (DP) is a sexual act tag indicating simultaneous penetration of two orifices. In doujinshi, this typically involves vaginal and anal penetration simultaneously. The tag is often found in gangbang or multi-partner scenarios. Artists use various techniques to depict the act, often with emphasis on the character's reaction. Related tags include 'gangbang,' 'anal,' and 'multiple male.'

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.'
