The light novel is superb. Very amazing, detailed and breathtaking. Just when you think the first novel is really good, the second one is more amazing. The third tops it, the fourth tops that, and it's filled with tests and puzzles, romance and drama and whenever there is action, Horo excels or bows out. The translation is really good. I'm on novel number 10. I stopped for now and I'll pick it back up when I feel the urge to read. It just really sucks that it's not done yet by Yen Press. The fan translation is done but I doubt they're anything as good as Yen Press translation.
It is very hard to pick which one is my favorite but if anything, in novel six when Horo presses hard against Lawrence at the end of the novel ... She's a really pervert deep inside. That scene is stuck in my head, lol.
BTW, you posted in the wrong section. This section is just for animations.
