Not sure what I want to say here.high and loud, the sound of your bell of the twilight...ringing..
all alone, it rings and echoes in the twilight
It's my understanding that Yuki wrote all of this music without seeing //SIGN. It's amazing how well the music fits into the series.
Well, anyway. I wonder if this "bell of the twilight" is just a random lyric or perhaps we could turn to the music for further explanations and deeper meanings of the series. It may be far-fetched, but it would be neat, and one more way of bringing the whole thing together into the best piece of work ever

Perhaps this refers to the bell heard throughout various places in The World in the //SIGN series. It is heard in Carmina Gadelica when Bear and Subaru talk. Also a couple other times. Once in a field and another time in Mac Anu, I believe.
I wonder if this is a single bell heard throughout the entire World? Or different bells in each Root Town that are heard throughout all fields reached from that Root Town?
Maybe it doesn't matter, but I enjoy pondering these things none the less.
Thoughts?
