There were some aspects of this book that, as I was reading it, I thought "I'll have to mention this in the review." This, like the second one, has a lot of training in it but it seems to drag less here. We get out main character working to control his power, and finding a... unique... way to focus himself. One of the new additions to the group has a plan totally separate from just surviving. We even learn that there are people with psionist powers who aren't affiliated with the whole psyren thing.
But man, when I got to the last issue of this book, that was all that really stuck in my head. But since we didn't get to see much of it, there's not much to talk about other that wow, that was a heck of a way to end a book of manga. :)
