I think the latest volume released in the US at the moment is either fifteen or sixteen. I forgot. XD
They're eight bucks a book, so they're not that much of a dent in your pocket (unlike Prismacolor Colored Pencils, freakin' twenty dollars for a pack of 12 /rant). But, I can see your point. :3
Lucky you. My dad thinks the only way you can get a virus is just by going on pr0n sites, so yeah, he won't install/update any anti-virus programs. I know nothing about programing, and I'm afraid I'll mess up the computer. And the last time I went to MangaFox, it randomly tried to open Adobe Reader. O.O As you can see, I'm paranoid.
