Seraph of the End, Vol. 24

Asuramaru and the other black Cursed Gear demons' betrayal of their hosts strikes a heavy blow in the war against the vampires, Shikama Doji, and the Hyakuya Sect. Shikama Doji has ordered Asuramaru to capture Mikaela's soul before he has a chance to possess anyone. While Shinoa continues to fight to keep Shikama Doji locked away, Yuichiro and his friends are in a race against time to save Mika in the one way humans know how to handle black demons: by binding his soul to a new Cursed Gear weapon!
