Volume three which bridges the gap between the second and fourth events, and sees Maple transcend humanity. Three times. Now I have to wait for the fourth event and the big showdown. Which sucks. At least it's out this year. Volume 5 is out March next year!
So, I've been reading these in part because I am a big fan of the anime. It's been interesting comparing the original novel and the anime and spotting the differences, and there are differences.
The biggest difference is Maple Tree guild's home. In the anime, this is a big, hollow tree, and rather cute. In the book, there's actually a home on each level (or stratum) and it seems like they are all just fairly normal buildings. I think the change for the anime was a nice touch. More character.
In the book, we also get an explanation for where Maple's Counter skill comes from. I think the anime just left you to assume it was part of another power set. It kind of emerges in the fourth event without explanation. In the book, it was something she spent the third event, the cow/bull event, working toward. That third event gets a lot more detail in the book. Generally, there's more detail to be had here, which is not uncommon in a book-to-TV adaptation.
Oh, the anime added the beach scene, but not Sally's duel with Frederica. On the other hand, practically nothing has the same skill name between the book and the anime. I'm not sure whether this is different translators, or the scriptwriter for the anime deciding to use different names. Some of them are better, some of them are not.
Overall, this is kind of a bridge book between two major events, but it reads better than that sounds. One feature which has been downplayed in the anime is that Maple's guildmates are almost as 'scared' of what she'll do left to her own devices as the game developers. This makes for some amusement, such as when Maple picks up a certain randomly found gear after falling down a hill, and Kuromu/Chrome (the other great shielder; he's Chrome in the book translation, which is obvious now I look at it) gets a sudden chill, as though something bad has just happened or is about to. Similarly, the continued interplay of conversation among Maple's fans in the game room (which is readable in the book, unlike the anime) is amusing to read.
Mai and Yui, the two hammer-wielding destroyers make a whole bunch more sense in the book and are a welcome addition to the insanity of Maple Tree.
A lot happens and also a not much happens, but this is a good read. It suffers a little from over-explanation, which is a common issue with Japanese light novels. Some of the stuff cut from the anime (to shoehorn in more kawaii, I suspect) could have done with being kept in, so giving this a read was well worth it. Must admit, I may put the fourth volume on pre-order so I don't forget it.
