It's got pretty good art, in particular I think the artist has a very decent handle on the bishonen-smoldering-look.

Anyway, though it's not my favorite manga of all time, I like the supernatural folklore (versus your typical school-life shoujo), and I like that it goes beyond the "yay, we like each other, let's hold hands"-and-then-the story-ends.
Basically, if you like Twilight, you'll like this manga. (Though, I gotta put in a warning for any younger readers - it can get a little racy/hot and heavy/whatever-kids-are-calling-it-these-days so be aware.)
Anyway, there's a part where Kyo (tengu boy) gives Misao (girl) his longest feather for protection. He makes it into a necklace for her to wear.
Long story short, I made my own necklace and pretended Sak was a tengu and I stole his feather. Muahaha.
Want to make one? It's really easy, just need a couple feet of black chain, black feather charm and a couple jumpers! Should come out to around $5 depending where you get your supplies. :)
The best part is you can wear this type of necklace anytime, and be covert-otaku, unlike wearing, say,a giant Magic Knight Rayearth mirror pendant around your neck. @_@
