When he set off for the Capital, all Tatsumi wanted was a way to make money. Instead, he finds himself rescued from a fate worse than death by a group of assassins known as Night Raid, and thrust into the middle of a bloody revolution. On the one side: Prime Minister Honest, his secret police, elite squad of assassins, and the armies of the Empire. On the other: Night Raid and a handful of rebels desperate to overthrow the brutal regime of Honest's puppet emperor.

The convoluted path that has reunited Tatsumi and Esdeath takes another twist as they find themselves transported to a remote island where their strength will be tested as never before. Dr. Stylish may be dead, but Danger Beasts still remain, and that's only the first challenge the two enemies now face.
