Nightly Life of Raising a Vampire

When Ace, Sabo, their crew, and young Luffy get accidentally stranded in the Grand Line, help comes for them. But, will the Whitebeard crew accept a CHILD vampire, something that is seen as highly taboo in the world, who also has some increasingly powerful abilities? And if they do, will the Spades in turn accept them? Lots of fluff and unrequited Ace/Marco on the side.
