Anyone knows the song played in episode 12 of Naruto (classic btw), when Kakashi is speaking with Inari? And it's not sadness and sorrow, neither grief and sorrow.
Do you mean the music from the scene where Kakashi is out with Inari out on the pier at night?
It sounds to me like a guitar-only version of Alone (OST 2 track 18). I don't think there's an official release of this variant, but there are imperfect fan-spliced versions.
