D. Gray-Man, Volume 9 — Katsura Hoshino

Hordes of akuma are arriving in Edo to join the Earl, who has found a nefarious use for one of the greatest of all Biblical artifacts. Meanwhile, one akuma has invaded the Asian Branch of the Dark Order to take care of Allen once and for all. Allen doesn't appear to stand a chance, but the very nature of the akuma's attack starts something no one could have anticipated, and might wind up changing the fate of the world!
