At first I thought this was just dramatic build up to get played but there's only 2 chapters left so this lad might just finish this.
Also they really just point out what's happened to the city and JUST the city. So is the rest of this world okay and this was a isolated event, or maybe the focus just doesn't wanna bring it up. If it was said earlier I've totally forgotten cause this manga at times seemed a tad hectic .
Thanks for the chapter.
