In an interview with Purple Sky magazine, released December 15th, vocalists Gackt and Jon had this to say about the concept behind the song:
JON: Our next single, “All My Love”, it’s another take on an instance of a tragedy that would be happening in the earthquake. It’s about a couple and one of the people is killed, and how the person who’s left behind feels. What they need in order to move on as well.
GACKT: We don’t make songs as a negative. We’re trying to make those songs as a message.
