This is the last volume of the manga version. That's right. There're only two volumes total.
The ending is a bit smarter than that of the anime version. I liked the anime version's ending, too, so that means I like this one even better. The only gripe I have is that Mana and her friends aren't featured much in the manga. But then, I can always watch the anime to get that fix, so it's not a big deal.
If you liked the anime, I recommend you pick up the manga version, too. You'll get a more complete picture of the story with both. Manga version is licenced by Broccoli Books USA already, so if you can't read Japanese, that's not an issue either.
