One of my favourite artists yes he does some ugly bastard but story and art makes each page hot especially his coloured works just hope one day the coloured version of Chizuru-chan’s development diary gets a release

Great works, I hope to see more of their Precure doujins on here someday, but the selection they have on here is top notch.

The best artist featured on this site at the time of this post.
His works feature girls getting fucked by fat old men predominately like the bio says and the girls go through moral degradation/corruption in the doujinshi. If that ain't your thing then I wouldn't buy any of his works but do reconsider for the art alone as it improves by a fair amount the further you progress in Development Diary.
