I remember reading something about Sudoo Kaoru, the author of Gretel, quitting manga because of death threats from homophobic otaku who were for some reason reading Yuri Hime S. I also heard that he suffered some injury/illness that forced him to quit. Does anyone know anything about this?

I kind of wonder if he'll ever make a return since series in Yuri Hime are now more explicit than they were just a couple years ago.
