Abandoned {D. Gray-Man x Black Butler crossover}

Allen's been abandoned by his own family, friends (at the order) and humanity in general. His only family are the Noah and his only surviving, real family, is Nea. After a while he decided to travel far, FAR away from everything for a while; with his uncles help of course, but soon he stumbles upon a shop that seems oddly familiar to him. Allen soon recognizes the shop somewhere in England he remembers that a man with long grayish hair, a scar across his face and wears long rags- or so to say, lived there. This man had taken care of Allen before Mana had found him wondering about. Allen thought the man had left him but turns out he's been waiting for him all this time, working as an Undertaker.

●Disclaimer: I do not own Black Butler or D.Gray-Man but I will say I own the story line that will be written in this book.
♤ Quick note: I got this idea while reading a crossover of the two and wanted to give it a try.
