???: "Your next mission is... Destroy the enemy."

When Baku reached a call from someone who's definitely not ZERO, he tensed. What was CODE trying to hide..?

What are CODE's relationship with the Nightmares who cause mayhem to people's dreams? What CODE plans to do with everything after attempting to kill Nox (formerly Code No.4)?

The answer lies behind....

Baku immediately heads back to the base, unaware of something that might happen next.
