Hmm, to clarify some kanji things a little, 唭哩岸 doesn’t really contain 里 - you could say that 哩 “contains” both 口 and 里, which individually are kanji that have their own meanings (“mouth” and “village / hometown”, in this case), but it is fairly common for a single kanji to consist of multiple shapes that might have individual meanings, but for it have little to nothing to do with those individual meanings. For example the kanji for “black”, 黒, has the aforementioned village kanji shape and four little lines below it, but doesn’t really have anything to do with 里. It merely happens to contain the same shape, but it doesn’t contain the meaning of 里. There are probably numerous other kanji that contain the shape of 里 somewhere, so the connection between Maria’s name and Qilian (唭哩岸) seems pretty insignificant and coincidental, hardly something worth getting agitated over for Kinzo.
哩 and 里 are two completely different kanji, two completely different characters. It’s kinda like how 1524 “contains” 52, but the numbers 1524 and 52 don’t really have much to do with each other.
In any case, your work with the epitaph - and the playthrough in general - has been impressive beyond all expectations. I look forward to seeing you reach the golden land at the end of your long journey.
