YMMV / Painless

• Awesome Music: Superfly composed the song "黒い雫" (Kuroi Shizuku - "Black Droplet") specifically for the series. It's a rousing rock song whose distinctive guitar intro marks a lot of end-of-episode twists throughout the show. Combined with Shiho Ochi's powerful vocals, the track is somewhat reminiscent of a James Bond theme song.
