D.Gray-man

Allen continues his transformation into Nea, the mysterious Fourteenth inside him. When a shocking revelation from the Millennium Earl traps Allen in Nea’s spirit world, he desperately seeks to understand the entity that’s using him like a puppet. Perhaps his own past can offer some clues…

Kanda, Johnny, General Tiedoll, and Link listen as Allen tells of his past, about the incident at the Garvey Circus where everyone except he and Mana disappeared, then of how he and Mana journeyed together until Mana passed away. This leads the group to puzzle over the mystery of the holy war they’ve been fighting for so long. What is it really about? It soon comes to light that a clue may be discovered at a certain old bookshop.
