D.Gray-man, Vol. 11 — Katsura Hoshino

The Noah, however, seem less interested in the grand plans of the Millennium Earl than in collecting payment on yet another mountain of debt accrued by Allen's master, General Cross Marian. Can the Exorcists find the literal key out of this potentially lethal predicament?
