In the anime series Trigun, the main character Vash's way of life is shaped by Rem Saverem. Rem was Vash's first (and possibly only) love who had died years before, and this picture was inspired by a scene in episode 12 (Diablo), in which Vash is admiring a beautiful sky and thinks, 'There I go again. It's stupid, isn't it, that I want to show you these things, even though that's no longer possible.' What if it was still possible for Vash to share these moments with Rem? 'Sound Life' is a reference to Rem's theme song.
