One I remember enjoying very much called "Dragonfly" is about an assassin and a Japanese man with curious infliction that sends him to illegal drugs just for relief. That story is at about 40k words and about half done. I've got a few other first chapters started of other ideas but I think most of those might end up being free (on AF fiction).
Lastly, I'd like to send you to www.thebeautifuldeath.com for a new Urban Fantasy series featuring Japanese mythology and alchemy (vampires too!). The cannon love interest is a hetero relationship, but many of the side relationships are "other".
I'll do my best to not be a stranger in 2014 and get new stuff in your hands. :)
