D.Gray-man Volume 16

Blood & Chains Lenalee is determined to confront a Level 4 Akuma that's out to kill Komui, but her only chance is to reclaim her Innocence and synchronize with it. The Level 4 is not inclined to wait around and pursues its mission even against the best efforts of Lavi and Kanda. It's left to Allen to hold the line, but it soon becomes obvious he has no hope of doing it all by himself!
