I'm only about 85 pages in and already it's incredible. Tezuka's imagination simply astounds me. It's just great.... simply great. I think I'll sleep with it under my pillow tonight.

The one thing that is confusing me a bit is that according to Viz's published "Phoenix timeline" the next story should've been "Robe Of Feathers". I've heard that it's not a long story, so I'm still hoping that they've just temporarily skipped over it in order to pair it with another shorter story in a future volume... and not just skipped it. I'm not familiar enough with how the phoenix series breaks down to give an educated guess yet. There's 12 stories... but it looks like it's been released in a variety of formats in various langauges - everything from 9 to 16 volumes.
The fact that there's only listings for volumes 7 and 8 gives me pause, but the fact that I'm holding my copy of vol. 6 against all odds tells me not to worry just yet.
