Yu Yu Hakusho/Ho Yay


 * The most understated pairing in YYH is Kazuma Kuwabara and Yuusuke Urameshi.. From the premonition of a kiss, to one or the other going full-blown hysterical whenever they other is hurt-- except in the instances when they are hurting one another. They are the quintessential guys who hate each other becoming best friends. The focus is definitely on Yuusuke's emotional outbursts increasing his rei-ki and it's usually Kuwabara who is the one who has to get injured in a big way for him to peak.
 * More acknowledged is Hiei and Kurama. Though both tend to be introverts on the show, Kurama is the only one that Hiei appears to trust completely, even showing up at Kurama's ningen home more often than not. Also, Kurama mentions whenever they're fighting Sensui that "this might be the first time Hiei has ever been willing to die for anyone other than himself". This is actually untrue because when Kurama was knocked out after his fight with Touya, Hiei almost released the dragon of the darkness flame whenever Kurama was being thrown around while unconscious even though it meant that he would die at the time since he hadn't mastered it yet. Kurama was unconscious so he never knew he was about to do that. One is rarely seen without the other, and there is promotional art for the series where Kurama is hugging Hiei (the fact that he can do this and live says something right there) and one where he has his arm around him in a very possesive manner. Most of the official art shows Hiei and Kurama together. One thing you will notice is that they hint towards Hiei and Mukuro only in the anime. The whole scene with Hiei falling into Mukuro's arms never happened in the manga. Neither did the scene where Kurama tells Hiei he's not interested in him. It's rumored these were added to ward off suspicions of them being together.
 * Wait, when did they confirm the two knowing each other in the Makai? The Maya side-story confirmed that Kurama at least knew Hiei's reputation, but it was made pretty clear that they didn't actually know each other. (plus half the story is about Kurama not being able to admit he loves this girl for whatever reason)
 * Well it's not really confirmed he loved her. The reason he could obviously never be with her (and honestly why would he want to) is because he hadn't planned on staying a human at all. He still really doesn't. When it comes down to it, he's a demon and that's all there is to it. Also I think they've both heard of each other but I don't think they had a past together specifically. I'll take the liberty of removing whoever put that.
 * Not to mention Yusuke is neck-deep in Foe Yay with all of his male enemies at times.
 * How about Kurama being Foe Yay with Karasu? Major one there.
 * Even Togashi shipped Karasu and Kurama in his doujinshi Yoshirin de Pon!
 * How about Koenma and Ogre, "You'd look a little suspicious carrying a teenage stud in your arms." It is fairly abusive, but still. Also whenever Koenma says "Why don't you ever talk to me like that, Ogre?!" during the dark tournament.
 * Ho Yay is Togashi's forte. It's very difficult to look at ANY two males' interactions in Yu Yu Hakusho OR Hunter X Hunter without seeing something there. Yuusuke x Kuwabara? Kurama x Hiei? Itsuki x Sensui? Yep. Killua and Gon? Leorio x Kurapika? Even Hisoka x Gon, it's there kids! Tons of Foe Yay in both with the protagonists and some villains? HELLS YEAH.
 * Either Togashi is really oblivious when it comes to making friendship seem like friendship, the couples are real, or they're just a huge shiptease.
 * He's a GLBT supporter so ...
 * Well, Itsuki/Sensui isn't exactly Ho Yay...
 * And of course the whole thing is mocked in The Abridged Series....via Botan writing a Valentine's Day Special Fanfic. And BOY, do we mean special.
 * And you can't forget his fanservice with Hiei/Kurama in episode 18 when Kurama bitches out Kuwabara only to have Hiei pause and quickly say "Iloveyou..."
