Kurama isn't gay. Trying to say he is 'coz "The boy's hair is as long as his but" and "The man fights with flowers" is completely unfair. People have different tastes. So what if likes his hair long? I've seen people that have long hair and aren't gay. He fights with flowers? So? I think it matches his personality plus demons are born with the ability to control specific elements. Do you think Kurama can help it if he got the ability to control plants? And about that Kuronue thing, they were close friends. Like brothers, I would guess. Wouldn't you be sad if your brother or close friend died?
By the way, Maya and Kurama were never together. I'm not sure if the anime said anything about it, but, in the manga, Kurama had found out that she liked him the same day he met Hiei. When he found out, he told her that he didn't like her, even though he did which proves that he does in fact like girls, to protect her. Then that's when Hiei attacked. Later that day, he erased her memory and I heard that he grew his hair out so that she wouldn't recognize him.
Since that's out of the way, I would like to comment on the pics.
Personally, I like the first one. What does it matter if they're nearly touching? That doesn't prove a thing.
The second and third one make it seem like, since they're fighting partners, that they just watch each others back during a fight.
That third pic just looks like they posed for the camera or something. Plus, how come girls can pose like that and people will assume that they're best friends and that's the reason, but when boys pose people automatically assume they're gay?
4th pic: Actually, I find nothing wrong with that shirt. Is it the color that makes it the "gayest shirt you have ever seen"? Seriously, it takes alot of courage for a guy to wear pink. There's absolutly nothing wrong with it.
5th pic: Well, have you stopped to think that, since this show was made back from 1990-1994, maybe that's how people danced then?
6th pic: That pic is just Kurama cutting Yuusuke hair. In the episode "Topside", Yuusuke had said Kurama cut his hair.
7th & 8th pic: I see nothing wrong with those pics. They're... Sitting around... Is it gay for a couple of guys to sit around?
As for that 9th pic... Maybe Hiei had... Something on his ear? o.O I dunno... That's the only pic that you've posted that's actually questionable.
