To me, it's far more like Ginko comes off genuine and Yuuno oozes "fake." They are both lying in a way, but Ginko has entered this world to stick closely to Shinkuro while Yuuno acts more like she has some sort of claim on him because she taught him all these things.

They both keep all their real emotions shut away, but Ginko comes off concerned or caring (though you'd never see her show it) while Yuuno inserts herself in all of Shinkuro's business because she has power over him.

Just picked this up a few days ago (obviously). Benika is very interesting. She reminds me a great deal of Balalaika from Black Lagoon, but more devious than ruthless. I'd like to know a lot more about this power struggle she seems to be having with the Kuhoin's. She seems to wield enormous power in the underground, but strangely, some people know of her and several people (specifically in the Kuhoin) have no idea who she is.

I also enjoy how Murasaki talks like an old woman. Some of the characters view her as very mature because of it (like the baths lady), and others look at her strangely.
