Netorare Genre

""This made me depresssed.""

- A Crossing Man and Woman reader, summing it up perfectly.

Netorare (寝取られ, lit. "cuckold", also commonly abbreviated as NTR) is a notoriously controversial genre of Hentai (or in rarer cases, Ecchi), with a degree of infamy perhaps rivaled only by full-blown Guro. Even the horniest /d/viants are resistant of embracing the genre, and if one finds an example uploaded at certain shady websites, one would only need to look at the comments section to see the Internet Backdraft that will inevitably ensue.

On the bad side of Good Adultery, Bad Adultery, and as its name suggests, Netorare is essentially a genre whose goal is to project discomfort on the audience's part (much like horror flicks are intended to provoke unintended bowel movements), where the discomfort comes in the form of sexual jealousy. Typically, a heroine will be introduced as having a significant other, which may be a husband, a boyfriend, or even a partner in a BST affair. The story will then show the aforementioned heroine being intimate with another man (another girl just doesn't pack the same punch), thus provoking jealousy in the audience by proxy. The nature of the affair varies, and the parties involved may be willing or unwilling: sometimes the girl is simply cheating, sometimes it's in the form of a Scarpia Ultimatum, some other times, it's rape, or the man may simply be pimping his sweetheart out to earn their bread.

Of course, the parties involved may be of either gender. Most Writers Are Male, so commonly it's the woman who engages in the proceedings. Also, it doesn't have nearly the same effect if the genders are switched; in fact, most of the guys love it.

As one might effortlessly predict, many people seriously detest this genre/trope. It might have to do with the oft-idealised nature of relationships in the anime/manga culture, along with the fanbase's obsession with purity—a phenomenon apparent by the popularity of tropes like Sacred First Kiss, Lolicon, Yamato Nadeshiko, or Moe. That is to say, Otakudom seems to have a strong connection with a specific, sugary perception of romantic relationships, built around pure, sincere, genuine commitment. Hence Netorare, being at the opposite side of the Sliding Scale of Idealism Versus Cynicism, tends to rub people the wrong way. In spite of all the hate, some people are genuinely attracted to this kind of stories, for various reasons. Inversely, most fans of the genre are also obsessed with purity, which is what makes it all the more enticing when that purity is broken.

See also Adult Fear, Defiled Forever, I Have You Now, My Pretty, Please, I Will Do Anything!, Sacred First Kiss, Scarpia Ultimatum, and Your Cheating Heart. Very often features an Idiot Plot, and is perhaps one of the few non-comedic techniques which may execute it to good effect. The reverse of netorare is netori, cuckolding someone else's love.

 * Jairo, "Para verte feliz" ("To see you happy").

"Mess with their heads. Get it so the victims love their keepers, will do anything for them (even better if they can work one of the couple against the other--so sweet, that betrayal)."
 * It's not surprising that this happens in Vampire: The Requiem. Netorare is usually just implied with the art and a few throwaway lines, but there are some large, heart-breaking plots that emphasize it.
 * Ancient Bloodlines speaks of a vampiric Babylonian priestess' lesbian lover being taken from her forcibly by the En emperor. Turns out the lover eventually fell for her abductor in typical NTR fashion. Unlike other netorare stories, the priestess got her revenge on them by creating the Iltani and edimmu.
 * The trope is taken Up to Eleven with the Honeymoon Hijackers Charles and Charlene Greengrass. They were kidnapped and turned into vampires on their respective wedding nights by cruel sires, with their spouses killed. Charles and Charlene meet one another ten years after their abductions, instantly recognize the predicament of the other, and fall in love. They diablerize their sires, escape vampire society, get into a scary codependent relationship, then perform netorare scenarios and serial killings on any recently married couple they can find.
