Ep. 10: Rentaro and Kisara investigate Monolith 32 before its collapse and the Gastrea invasion.

10

With three days remaining until Monolith 32 collapses, Rentaro and Kisara tutor Matsuzaki's Cursed Children, who visit the Flames of Revolution memorial site to show affection for Rentaro. That night, the pair investigate the crumbling structure and wonder why the Aldebaran Gastrea targeted it, prompting Kisara to conduct further research. The following day, Tokyo's population evacuates to underground shelters via lottery, while public tension against the Cursed Children escalates, forcing Rentaro to rescue a blind child from an angry mob. Upon returning to camp, Rentaro and Kisara learn Monolith 32 was privately commissioned by Kazumitsu Tendo. The next day, Rentaro and Enju discover the other Cursed Children were killed by a deliberate bomb drop. This tragedy causes Rentaro to fall into depression and argue against societal corruption. Suddenly, winds knock Monolith 32 down a day early, leaving no time for grief before the imminent Gastrea invasion.
