Edit Reason: More samples

I got a few files, some of which contain Japanese text and some of which contain names of other files, after an initial XOR step but I couldn't make heads or tails of whatever the next step should be. It should be some kind of compression, since it squeezes some of the intended dialogue a few bytes down from what they otherwise would be in UTF-8, but at other times it replaces a number of bytes from the dialogue with the same number of bytes, which I don't see the point of if it's intended to be compression.
I'd be grateful if somebody could tell me what this compression method might be.
(Included the original files before the XOR step, in case the compression happened there - though I doubt it, personally - as well as some of the text the two files should contain, and an initial attempt from me to compare the differences in bytes that didn't really go anywhere.)
