Mysterious Girlfriend X/YMMV


 * And the Fandom Rejoiced: When a TV series was announced.
 * Arc Fatigue: The Idol storyline went on for longer than some people liked (a year in real time) before the arc finally came to an end in chapter 48.
 * Audience Alienating Premise: To those who are bothered by saliva drinking, or to those who simply have trouble swallowing the premise.
 * Broken Base: The Idol arc. Not only did it take an extremely long time to resolve, but for many it also marked a change in Urabe's personality, causing her to ignore her increasing feelings towards Tsubaki and become increasingly hostile to his attempts to simply make physical contact with her.
 * Fetish Fuel: This manga runs on Fetish Fuel. A short list: glasses, spit/drool, finger-sucking, stoicism, weird tan lines, bikinis, short girls...
 * Plus short hair (the protagonist's personal turn-on), exhibitionism, school swimsuits and more than a little Les Yay.
 * ...ear licking, hair play, panty shots, possessiveness, body paint...
 * wears some easily visible restraining garters.
 * ...cutting off a girl's clothes, upskirt, downblouse...
 * Hadaka Apron!
 * We have eating raw bacon while wearing cat ears. ...Wait, what?
 * Everything's Better With Bacon!
 * which furthered into a hinting of a Catgirl fetish.
 * Face masks, fevers... when did this turn into Ai Kora?
 * Genius Bonus: The covers of the books contain rather large portions of the English language versions of various literary classics -- the original Frankenstein for Volume 1, for example.
 * Les Yay: Urabe and Oka, exchanging saliva whenever they have lunch (not like that! Granted, it's kinda kinky all on its own...).
 * Oka peeking down Urabe's top.
 * Magnificent Bastard:
 * Moral Dissonance: Urabe . There's also the case of the public property she desecrates by cutting it to pieces...
 * Squick: Sucking saliva off someone's fingers may not be the most romantic thing for most people.
 * In the anime it's drawn a lot thicker and gooier than it looks in the manga, with a slight yellow tint.
 * What an Idiot: Tsubaki, multiple times. Part of it is due to his naïveté, part because he has had the Idiot Ball surgically implanted and partly because his girlfriend is, quite honestly, really weird.
