Dos Obake Ga Nekasetekurenai
One of my personal favourites. Non-con as heck especially in the beginning, but Kousuke probably has one of the best looks of "desire" in any manga. Every time his switch is flipped, either as ghost or human Kousuke, it's fantastic. Was one of my earliest experiences with non-con fiction, and honestly, it got me into it.
Futari no Renai Shoka
I'd say I wanted more if I didn't already think it was perfect. This is honestly really good, I didn't even know it was made by the same author as Mahoutsukai no Yome, but I'm really not surprised that it is! A satisfying conclusion that left me with nothing but a clear heart and mind. Love it.
