Business model:
I'm not familiar with a lot of the manga related terms you used but it sounds like there is some copyright infringement going on.
I'm not sure how using bitcoins will make anything different. Are you just trying to make it harder to trace who does what?
The goal here is not to run foul of copyright laws, but to provide a legal, reliable, and convenient source of manga for the public in form of online reading sites. As it stand, these illegal online manga reading sites can get taken down anytime for copyright infringement.
It is a niche that needed to be filled.
Please explain the copyright situation better here. Are there artists and designers who would be willing to publish their original work in a new medium (on-line) and be willing to get paid potentially with Bitcoins, or is this merely somebody who has copies of the manga and has posted scans of this stuff?
The "legal" aspect is what I'm trying to get a handle on, and where the "copyright infringement" comes from. If a site is "illegal" and "infringing copyright", it sounds like this is something that the Bitcoins aspect is irrelevant on. If this is merely trying to provide a revenue model for artists that want to get outside of the normal publishing model, there is certainly something that Bitcoins can get involved with that can make them some serious money.
