Okiraku Ryoushu no Tanoshii Ryouchi Bouei (English subtitle: ~PRODUCTION MAGIC Turns a Nameless Village into the STRONGEST FORTIFIED CITY~) is, just as its title would suggest, a pretty carefree story. The protagonist has a personality similar to Tensura‘s while the plot developments and general character behavior is over-the-top in a fairly random manner. It’s a fine time-waster, just don’t expect anything from it.
The second Gekka no Shoujo Asura novel is much like the first. Except with a bit more perversion, a bit less action, and an ending partway through its plotline (although admirably not on a cliffhanger). I’ll probably grab the next book to see how the arc concludes… but I’m not sure I’ll go any further than that.
