This volume contains several different stories, all of which can be read individually. (Although I will admit that I have my preferences for specific stories.) This is one series where every volume has been just as good as the first. I'm familiar with Tekuza's work for the most part, but I've never actually been able to collect & read his books in the past, so this is really eye opening for me.
I have to admit, I'll be a little sad when Vertical stops releasing the Black Jack series when they reach the last volume.
