Oooh, that's interesting. I haven't checked what the line means yet, but copying and pasting it directly into Google is turning up all sorts of
results. (Ugh, it appears to be Xeno-related but is loading far too slowly for me when I try it again)
Kato did at least some or all of the script writing for Xenogears IIRC, so it'll be really fascinating to see how this turns out.
EDIT: Oh, is it the Japanese equivalent of the "Let love bleed" line from Chrono Cross?
EDIT AGAIN: The site I tried to link to above translates roughly as:
Japanese to English translation

It looks like a description of an early section of Xenogears, so it's plausible that it could have appeared in a demo. I don't remember a line quite like this in the English version of the game, so we'll have to track down the Japanese demo and screenshot this puppy. I'll bet the Xeno-sages over at the GameFAQs board might know more about it too, since a few people there seem to eat and breathe Xenogears.
