He deleted almost everything from his Pixiv and Twitter image posts going back to November last year. Google translate isn't the most the reliable but he sound really stressed and depressed from the tweets he is putting out lately.
Edit: Seems the recent tweets he made to vent are now deleted.
I think he is pushing himself too hard to put out his monster girl works and making himself ill. He also seems upset about the low sales of his works.
Edit: Now he has wiped all but two posts of his Twitter.
