Final volume is out over at Amazon and whatever outlet that sells Light Novels. Here are the chapter titles:
I'm about a quarter of the way in at the moment so I'm just guessing those are how the titles are meant to be taken in the context of the volume sypnosis so they're still subject to change given how chaotic I expect the end to be. I'll likely post my final thoughts on in the series in a review like maybe a week or two from now. I hope that everyone else keeping up with the series raw enjoys the finale at least as much as I'm expecting myself to.
Also, no worries about the illustrations. MountainOfPigeons came through on that front a few days ago after learning I needed them. Give him a pat on the back if you see him. I'll have the remaining volumes up maybe next week in the gallery but don't expect the spoilers to come with them since I'm still expecting to be tightly locked into real life commitments for the foreseeable future.
