Artist: Joe Hisashi
This song is from the Howl's Moving Castle Soundtrack and that scene inspired a huge part of Kai's story, the swallowing of the star. I had the character already - this sleepwalking boy who wakes up in the bed of his crush - but this scene inspired this notion of what set Kai apart. I loved the idea of a strange boy having a tiny universe inside of him which spawned Akuma's character and from there the story grew. So, although musically, this doesn't really go with any of the other songs, it has to be the first.
Artist: Des Rocs
Appropriate for Kai's life in general, but particularly for waking up in the predawn of L.A. Came across Des Rocs recently and I feel like a lot of their music fits the darker, edgy visuals I associate with Kai's story in my head.
Artist: Des Rocs Kai and Akuma sneak into the FBI while Mason goes to finally recover the case.
One of a Kind
Artist: Lit Akuma in action in the last fight. I came across this song years ago from a Naruto AMV that was superb. Seemed appropriate to include it since Akuma is such a fan of Naruto. (Couldn't find this track on Amazon either but it's on Spotify.)
