D.Gray-Man 12

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.

Fight to the DebtKrory, trapped with seemingly no hope of escape, receives a visitation from the last person he thought he would ever see again. As for his comrades, they continue their struggle through the Ark until they meet up with Tyki Mikk, who wishes a palaver with Allen Walker before there is any further fighting. Allen reluctantly agrees, unaware that Lavi is feverishly mulling over mounting evidence that Innocence is far more, and far stranger, than anyone had previously imagined!
