- BLOCK attempt to take advantage of the loss of communications with the Hikoboshi II and a security rotation interval to get 5000 external mercenaries into the city. Due to the intervention of Etzali, the alarm is raised and the majority of their mercenaries are decimated by a trio of HsAFH-11s.
- The survivors attempt a raid on the Reformatory, targeting Move Point's associates to gain leverage against her, in order to sneak explosives into the Windowless Building to destroy it and assassinate Aleister.

- Etzali's real name is finally revealed.
- Musujime Awaki's previous role as guide to the Windowless Building is referred to, being a key part of BLOCK's plan to assassinate Aleister, with her allies from the Tree Diagram Remnant Arc, imprisoned in the Reformatory, being targeted by BLOCK in an attempt to force her to cooperate.
Differences in Adaptation
- Because the scene where Tetsumou is tasked in rooting out the traitors in BLOCK was cut, Tetsumou's Skill Polygraph is never featured. Instead of having her fingers blown off as the result of Etzali's actions, she is instead caught in the Six Wings attack. Her fate is unknown.
- An original scene is added in the episode where Frenda is shown being beaten up by Kakine.
- In the novel, Musujime Awaki tells Teshio Megumi that the Windowless Building is actually not a building, implying that she doesn't know the true nature of it.
- The nature and the purpose of the device which Awaki has torn off her back (and even the fact it's the same device which was shown on her neck in the episode 24 of the previous season) was never explained in the anime.
