Eerie Japanese video game

[piranhabites]

Okay, so I remember playing this video game demo over and over as a kid. I think it was for Sega Dreamcast, though it could have been PS1. I think it was on one of those sample discs with a bunch of demos. Probably from somewhere between 2000 - 2003. It was a Japanese game and you were in a village. It was nighttime, and there was some kind of looming threat - monsters or demons or something. I think you were a character with purple hair. You could wander around... I think that someone asked you to find someone/something. I remember there being a pit/hole in the middle of the village, maybe? I don't believe there was any action or fighting involved, but I remember being really creeped out and intrigued by the game as a kid and have had no luck since in finding it!

Thank you! :)
