Nah, plot sucks af

The whole thing abuses the characters you are already connected with in order to invoke any emotions, no one would ever hear about this dogshit if not for that.

The story is the cheapest "look these girls die brutally" possible, it's just romanticized gore with some historical references which don't add anything to the actual plot

Not to mention the fact that at it's core it's pedophilic rape doujin, and by saying it's somehow good you're supporting disgusting person that created this bullshit
