i don't see all following through, but I can see where more will than a lot of other artist / authors. Think about it, it's not like 100 issues of a regular manga. How many pages are in a normal manga issue? How many panels in an issue? So figure they have to create some where between 4 to 8 manga issues. Now add to that in this one and even the croc there was very little true plot so the story is much easier to come up with. Look at the three here, from page to page there is no real connection other then the drawing is of the same character and reference to an otaku.
If you are doing this type of work art/writing or wanting to, for minimal work you get 100 issues of exposure plus maybe some donations.
