So... these art pieces are propagating some kind of curse where the art "escapes" if people don't look at them and then follow those people who are interested in art, which then causes fear and terror until they die? Or something like that?
And it's put into question if the thing the art is based off of was something that only first appeared when the artist saw it for the first time, or he only saw one of the many things that "escaped" from somewhere and there could be more roaming around somewhere.
Also, so Yume said that they shouldn't take their eyes off of the art, but Yamu was doing that and one of the art pieces was wandering around and went behind her, but she fainted out of fear but was fine afterward. So why was she in danger if she was supposed to look at the art? And when she fainted and avoided the thing behind her, why did she escape the danger of whatever was supposed to happen if she didn't look at the art? And what happened to her partner on the floor? I dunno if I missed that.
