This is definitely a sick pleasure, not only to be the villain, but to be one with absolutely no redeeming personality traits.  Not only is the MC a complete psychopath, but some supporting characters are just as bad in how they abet and encourage him without any apparent consciences whatsoever.  It's equal parts thrilling to be such a baddy, and sad to realize people like this actually exist.  Character psychopathy aside, their motivations and interactions are otherwise all quite believable.

Technically, the illustrations and animations are very satisfying.  I only can't help thinking the grandmother was a lost opportunity to introduce a slightly plumper or more hippy figure...as a way to include more variety.  I'm waiting to see if Carola's daughter will become a play-toy, too.  Loli is popular, but not always licit.
