I acquired the entire soundtrack and yet there's still a song missing. I'm looking for the song that plays when Tsukasa, Mimiru and Bear are talking to Harald and during the last few seconds of the final episode. That beautiful violin song. If anyone could tell me what it's called or where I could find it, I would appreciate it very much. :3

Turns out it's features in Liminality under the name Grandpa's Violin, except it has a piano in the background. Anyone know where I can find the SIGN version without the piano? :3
