Title: Just took a brief pass over chapter 4 and tweaked spelling/grammar...

There are still a number of places left where the grammar, diction, etc. is a bit awkward. In some cases I'd like to compare with the Japanese original to be sure that I don't change the meaning while trying to make it read smoother, but I don't have any more time for that today.
