I've gotten up to volume 22 to find out that only Zatch Bell! Volume 1 to 25 were released to the US before Viz discontinued it.
Why did they do that? I know you can read Zatch Bell! online, but when I have no internet access or I'm on a road trip I like to bring my manga collection to read.
I know they discontinued since June 2009, but why did they do it and I hope they can start it up again and finish publishing the rest of the volumes as they're like 8 more Volumes left to publish. I'm a big time and loyal fan of Zatch Bell and it's sad to see it get discontinued.
