After Section 3 pushes Suo and Hei deeper underground, BK-201 must resurface to steal an object known as Izanami. The mission could get complicated - the agent tasked with guarding the object is none other than Kirihara.

Suo and July find themselves in a dangerous situation thanks to a double-crossing supposed ally. Later, when the young pair is abducted by an especially sinister Contractor, BK-201 must spring into action.

Suo encounters someone she thought was dead and learns the truth behind the mysteries of her past. Unfortunately, the meeting is cut short when several Contractors launch an attack.
