I think I recognize that character? Oh shit, I do know that character. Sort of. I think the artist's name was Staruri? I remember that artist liked drawing some twisty Mari's, and maybe made picrel? I can't recall. I only remember because we had an anon over in /homog/ ages ago who took a shine to Star in picrel and kept her in public consciousness for a while.
I don't have an answer to the second question.
