desu, it's a lot more for the contrast of angel vs fallen angel, as per Nari's notes on those designs
You have Hero vs Demon Lord (Hina & Nina, vocals)
Hunter vs Beast (Rin vs Momoka, guitarists)
Angel vs Fallen Angel (Ai vs Subaru, drummers)
Magic vs Might (Nana vs Rupa, bassits)
and then you have Necromancer Tomo

will post the translated DD one next
