I was pretty confused by the summary and thought I should just check out chapter 1, see if I like it. Didn't really want to, so I checked the comments, and thank you, everybody, I think I dodged a bullet.
Your memories of being a loving sister are you extorting money from her!!?? WTF is wrong with you!?!?!?!
I'm a little sad the Vampire Priest didn't get together with Hanna, but I'm fine with this. Just wish there was a little more hint at an actual romance between her and the princess, so I can gush over the ending.
