Hey, I need an opening identification. The only parts that I know are from a redalice remix. In the video they are all wearing like traditional Japanese clothes. There is a guy hanging, and there is a guy and a girl taking turns singing. The guy kind of it rapping and the girl has a really haunting melody. I really want to know what this song is from thanks. Pic is sorta related (hakama)
