Need Help Finding a Certain Music Video

[Sugar & Sins 156]

There's a certain music video I saw ages ago and I remember the video but not the song, i'm sure it was J-Rock and the video was like 2 guys running across rooftops doing parkour, I think one of them was like a demon guy? and when it cut to the band they were playing in a warehouse. 

 

Anyone know this? Cos me and a friend have been looking for ages and haven't found it anywhere.

I believe it's  Dorian Gray that has the demon on the rooftop but I could be wrong ?
