Fate of Soul～ピリオドの向こうの闇～ (Fate of Soul ~Period no Mukou no Yami~)

Background
"Fate of Soul" was first uploaded on March 22nd 2010; and is Samfree's third original Rin work, his second collaboration with CITRIN (the previous being "Yamiiro Alice"). Samfree mentioned in his blog saying he wanted to make a rather intense song, and how he thought Kagamine Rin's character (which he also commented as cute though he had made works of Rin before such as Promise) was somewhat fitting to the theme.

The song was uploaded for the compilation King Record x Creative Fun "VL-SCRAMBLE". It's one of the most notable tracks in the compilation which reached Nico Hall of Fame (exceeding 100,000 views). Other notable tracks include Signal-P's "UNBALANCE", or 40meter-P's "Crescent Moon Rider".

There's no definite plot to the song, for it only speaks of Rin singing about fate and fragments of memories. Samfree said nothing of plot as well, only leaving his video description to Fate of Soul as "And so a fate of one, an end of one."
