When the oddly peculiar Mikoto Urabe transfers into Akira Tsubaki's class, he finds that life has thrown him the weirdest curve ball ever. Because while Urabe may be an anti-social loner who sleeps on her desk, carries a pair of scissors in her underwear and breaks out in sudden fits of insane laughter, there's something about her that Tsubaki just can't quite put his finger on. Until he accidentally puts his finger in it, and suddenly the phrase "sharing spit with a girl" takes on an entirely new meaning! Before he can wipe her drool off his face, Tsubaki is mysteriously addicted to Urabe, which isn't half as strange as the fact that she not only finds this normal, but already seems to have plans for her new drooling boyfriend.

Now, now, now. I've been informed that certain people think that Nazo no Kanojo is ecchi. I've also been informed that a lot of people think it's bad that it has some originality. Well, guess what? It ain't so. Not often will you find an anime which revolves around drool, and this one did a damn fine job in doing so. So, you think that people sharing drool is nasty? Well, guess what, it is. Oh, but you watched only the first episode of the anime and took upon yourself to be an arse and immediatelly toss it aside? Well, guess what, not all anime read more

Ah yes. Mysterious Girlfriend X. When I heard that the manga was getting an anime adaption, I looked forward to seeing other people's reactions to the synopsis almost as much as the show itself. Perhaps a fair few WTFs amongst viewers who've never read the manga?

The story is simple. Boy encounters transfer girl. Boy deliberately tastes girl's drool on a desk. Boy falls in love with girl after that. Um, yeah.
The drool. If there's anything in this series that would turn off those who watch it, it'll obviously be the various saliva-swapping scenes. Personally, I don't think it's that bad. If it helps, think read more

It is safe to say that the core concept of which this anime is built on, the saliva mind meld, is pretty obscure, if not totally weird. However, although Nazo no Kanojo X goes to the absolute extremes of weirdness in some areas, it is perhaps the single most realistic in others.

So I'm not going to talk about the drool, that may be what drew me to Nazo no Kanojo X initially, but it is not what kept me watching, it is not the part that I love about this anime.

Most romance anime, especially school-based romance, are ludicrously unrealistic. We see the tsundere girl, the read more

"Upon discovering the existence of sex, every boy wonders one thing. They wonder what kind of girl they'll be with for their first time."

TL;DR: boy meets girl, hen things happen, no general romantic shit.

The series starts very cliched. We have The Ordinary High School Student, we have The Ordinary New Transfer Student... or not that Ordinary? Yepp, new girl looks weirdo, do weirdo things, drooling as hell and, in nearly everything, isn't usual high school girl, filled with shyness and taboos. That's cool, if you gonna ask me. Main Hero aka Akira-kun despite being at top of his sexual maturation is all round nice guy, read more

Anime: Inu to Hasami wa Tsukaiyou
Both main characters uses scissors and both anime are of the comedy genre.

Anime: Dansai Bunri no Crime Edge
Characters with an unusual fetish, scissors being similar to both series. They are attached to each other and also have a daily routine to be fulfilled.

Anime: B Gata H Kei
Young people make the same kinds of discoveries throughout. B Gata H Kei manages to be simultaneously more perverted and less disgusting, but then, it has a distinct shortage of spit sucking.

Anime: Chuunibyou demo Koi ga Shitai!
Welcome to mayhem. That describes the main characters life once they hook up with a girl who happens to look very similar in both series if one puts aside the style differences. Both end up putting up with a lot.

Anime: Bakemonogatari
Strange girlfriends, uniqueness, comedy, and drama. What else more could you want? Anyways, these two anime(s) are unique in their way of not only the story but the way it's played out. In both series, the protagonist meets a strange girl whom they eventually date and face other obstacles together. Both series has have hints of supernatural-like elements as well as being difficult to predict what happens next.

Anime: Aku no Hana
Both have similar male protagonist - quiet, ordinary boy.. that makes some kind of contract with very unusual, mysterious girl.
Both also have kind of 'erotic' theme.
AnH is dark,serious and somewhat artistic while NnKX is light-hearted and meant to be funny.
