I don't dislike Haiji's works, but I always feel that each story she makes is sorta incomplete-something is missing. Overall, she does have pretty good stories that need a whole volume as their own.
Sensei's works always make me happy. Her stories are quite unique and her artstyle makes them even better since one can really see the eroticism being depicted through her characters desires and love scenes. She is definitely one of my favorite mangaka's!
All that sexual tension /thumbs up/
