A few days after the capture of the woman spy, some of the extermination squad team from the nearby city arrive at the Black Fortress. After a few times of interrogation and torture, they find the spy is actually one of the chief spies from the Nergal Kingdom.
Knowing that there is a chance that she is killed or rescued by the Nergal Kingdom, the extermination squad decides to increase their security until they move the spy to their base.
While the extermination squad is busy securing the spy, Angus and the others continue their daily routine inside the Black Fortress. Although Angus, Jayna, and Anna are already enough to complete their graduation mission, they still decide to stay on the Black Fortress.
One of the primary reasons is the Ogre community. Even though they couldn't participate in culling down the Ogre community number with Borkins, they decided to help protect the Black Fortress.
