A bittersweet Len x Rin doujinshi that I think is based off of the "Daughter of Evil/Servant of Evil" songs.
scanned by me (Adorable Doujinshi Scanlations) https://adorable-scanlations.blogspot.com/
scan #198 (Almost to 200 wow!)
PS - Sorry for the blurryness around the bubbles near the binding. The doujin was bound very tightly and it was hard to get the pages straight. I don't like debinding my doujins. I like to keep my books in one piece.
