Thanks for the translation. It's a bit sad to see that none of the questions I had even got answers but at least they all got addressed. This game was a total 50/50 mixed bag for me. So I'm really not surprised by the lack of answers. A lot of stuff did get clarified/solidified, at least.
Aw, you beat me to it by posting this. xP I found this sometime ago too and remembered about posting it, but blargh. This english is 1000000x better than Google Translator's! Thank you so much for posting, it explained A LOT.
Also, "About Seto's grandfather, what did he used to do? Sai knows him, and the blue stone he left for Seto looks very similar to the blue crystal Shin had. And they also have the same voice...Is Seto's grandfather Shin?
--In the shopping district there is the message "I threw this useless thing away at the station". Is that P.F.? P.F. really tried to be helpful to Seto...Is that because of this?
-- A soldier or something like that used P.F. in the beginning. Originally, she was supposed to provide information for military purposes. But it seemed as if she wasn't a very useful thing to her previous owner. [/i]
