Cho Gono and Kanna are a happily married couple. You can clearly see the resemblances of these two to Harry and Hermione so I guess I don't have to elaborate. Unfortunately for these two, however, their happiness didn't last long. Kanna is kidnapped by a clan of demons. Cho Gono, in rage, goes and kills the members of the demon clan. By the time he arrived in Kanna's prison however, the damage had already been done. Kanna had been raped by the demons, making her pregnant with a demon child. Because of this, she committed suicide in front of Cho Gono.
	This is a picture of Cho Gono. Messy dark hair (though his is a dark brown color; similar to Dan's in the movies), glasses and green eyes. Sound familiar? All that's missing is a scar! He is also courageous and he has quite a moody air around him just like Harry in OOTP. Cho Gono had killed 1000 demons, turning him into a demon himself (this is similar to Harry's transition from a normal boy to a great wizard) and because of the genocide he committed, he was punished by the gods. Cho Gono was gone but here comes Cho Hakkai (I'm guessing Cho Gono's punishment was to serve the gods and the high buddhist monk, Genjo Sanzo. The gods also changed his name from Cho Gono to Cho Hakkai). He doesn't have the moody air anymore and is now a happy-go-lucky, cheerful young man who hides his anguish in a smile.
	The demonized Cho Hakkai (known as Cho Gono when he was a human) finds a second chance in love with Yaone, a beautiful demon (so this quite similar to Harry and Hermione being a wizard and witch) who also happens to be in league with the enemy. However, after one special episode, they share a very deep bond and whenever their teams engage in battle, only the two of them don't want to fight each other. They stand in a fighting position but they only talk of how they really don't think a fight between them was necessary. At times, they even help each other (though it's against their teams' desire) and are both very comfortable with each other (just like Harry and Hermione). Cho Hakkai looks less like Harry now, with a monocle instead of his normal glasses. That's 'coz only one of his eyes had a problem now since he tried to rip it off once (eeew!)
	Yeah, yeah, Yaone looks nothing like Hermione (unlike Kanna, shown in a previous image). She has purple hair instead of brown. But still, one of the main reasons Cho Hakkai is taken by Yaone is the fact that she looks like Kanna. Beside is one from an episode, wherein the faces of Kanna and yaone were superimposed. Yaone is similar to Hermione in the fact that she worries about Hakkai like Hermione does to Harry. Yaone and Hakkai also readily help each other (like H/Hr). And here's another weird coincidence: Harry=Hakkai and Hermione=Yaone
	Cho Hakkai had also been linked romantically to one demon lady (whose name I forgot) although this time, it was only in one episode. Look familiar? It's sort of a representation of Cho Chang. Dark hair, like Cho Chang's and of course, of asian descent. This was a quick attraction though. The girl died at the end of the episode (something like Harry's crush on Cho Chang quickly dying away) and Hakkai wasn't really affected by it (like Harry's obliviousness at the information of Cho Chang's new boyfriend).
	Here's another coincidence. Other than Cho Hakkai, Yaone is also linked with her master, Kougaiji, a red-haired demon. Kinda like Ron Weasley because of the hair. Although in my opinion, Yaone's feelings for Kougaiji is nothing but gratitude which stemmed from the fact that Kougaiji had saved her once. In Hakkai's case, I think it's true attraction.
