I like the choice of an enigmatic picture together with the suggestion that Gackt/Kenshin is hearing/sensing some message/music not readily in the consciousness of ordinary people.

I often think that people with an unusually high level of ability and awareness (sounds like Gackt, eh? And I expect that Kenshin was the same) are lonely because their experience of the world is different to other people's. The tension here between responding to something attractive and pursuing a line of duty is nicely described. Well done!
