Sakakibara Yui - Silky Rain video free download

Couldn't find this around here, so thought I'd share until taken down.

This came with Hapitora - Happy Transportation OP Single album as the second track. A very beautiful piece that's worth listening to if you're a fan of Sakakibara Yui. Even though the song's origin is a mystery~

I can't read Japanese; but, I'm pretty sure this visual novel didn't have a TV series. So, I'm assuming it's just a song Sakakibara Yui sang for some TV show. I mean, it's the same case with Tenjou Tenge's ED Single, Aishitene Motto.
