A cursed teenage boy saves mankind one soul at a time.

Set in a fictional 19th century England, D.Gray-man is the story of Allen Walker, a 15-year-old boy who roams the earth in search of Innocence. Washed away to unknown parts of the world after The Great Flood, Innocence is the mysterious substance used to create weapons that obliterate demons known as akuma.

It's been three months since Allen Walker's mentor, Cross Marian, pulled his latest disappearing act. Allen and fellow exorcist Kanda now learn of an odd new threat known only as G. G plans to steal a valuable crown from the Louvre, so Allen and Kanda join the local constabulary in trying to prevent the theft. This leads to a surprise discovery that could have no small significance for the future of the Black Order!
