DR623G also known as "Death Suppressants".
Death Suppressants allow magicians to live longer. Each 10mg dose of DR623G allows a magician to live for about 30 hours with no ill effects. Though some (Mako Fujisaki) can live longer than normal magicians consuming only one. Witches who don't consume a death suppressant will start to bleed through their skin and after 30 hours without consuming one drug, they will die. If they do consume one, the wounds will regenerate automatically.
