Ds Come In Pairs

Trafalgar Law is a descendant of the cursed D bloodline. Each D holds a power, but using it comes with a price. Law can heal any patient, but to do so he needs to absorb the life-force from another person thus killing him. He never thought that his next chosen victim, a straw hatted teen with too much energy to spare, will throw his whole world off its axis. (Modern AU LawLu)
