The Death busters are better known as the Witches 5 or "Bureau of Bad Behavior". This consists of Eugeal (Top picture).
Mimet (second picture down). Byruit (Third picture down). Cyprin (Forth picture down). Petriol (Fifth picture down). And Telulu (Last Picture).
NOTE: Cyprin and Petriol share a body and mind. So technically it's Witches 6, but they made it fun and short Witches 5.
NOTE: The photos are in the correct appearance order.
Pharaoh 90 is the leader of the Heart snatchers and has his own page. (He also does not have a great image.)
