Asa No Hikari's manga / #Humanoid(7)

A great read for a mature audience that can handle stomach-churning subjects. People who count Harada or Ogeretsu Tanaka as your faves, you'd love this. For those looking for a fluffy, sweet love, please look elsewhere. This will linger on your mind long after you're done. Truly proves there is no floor to human depravity, just like "Sabi no Yume", another unique story with similar plot points. It does have a happy ending, so you can look forward to that.
