I get what you're saying about Basara. Maybe Shuri, too, sees things more in absolutes where Sarasa, like you say, can see the bigger picture but also is more tolerant and sees the worth of varying points of view.

I have never read Blade of the Immortal, but I did just order Ohikkoshi, which is, I think, by the same artist.

ETA: Since we seem to like a goodly amount of similar things, I poked around with my new favorite tool (http://www.worldcat.org) and found a copy of this. Hopefully my library will be able to get it via ILL.
