Bungo Stray Dogs, Vol. 20

"Atsushi stands together with his rival, Akutagawa, before Fukuchi Ouchi--veteran of innumerable battles, friend to President Fukuzawa...and leader of the Decay of the Angel. If the two defeat him, they can clear the agency's name and bring the whole incident to a close. However, while they may have defeated powerful enemies before, nothing can prepare them for the might of the living legend known as the strongest skill user!"--Publisher's description.
