He's a pretty prolific hentai artist and AFAIK Prism was his first attempt at branching out onto a more mainstream manga, the tracing accusations pretty much killed his career and he went back to hentai. Than Stretch exists (and hopefully is popular) is a sign than they finally letting go and giving him another chance, with any luck this will open him some doors to do more (yuri?) manga and who knows?, maybe Prism can return someday.
