Welcome to one of my many Yaoi manga lists. Here you will find:
Psychological and twisted Yaoi manga with a dash of horror. Things can get really dark here, so be warned.
If you enjoy reading twisted stories, with twisted characters (much like myself) Then this list is for you.
As always, although dark... the manga on this list have nice, beautiful art and I have carefully handpicked them from all of the ones I've read so far.
