I actually dont have internet at home so what i usually do is download the
mangas from onemanga and read them at home. Iam trying to get this manga ->
<http://www.onemanga.com/Gantz/01>

iam trying to use wninhttrack but it wont let me doenload it becaue there is
like a mature warning before you could go to the main page. Would it be
possible to download it? thanks.
