Rentaro und Kisara kommen einem dunklen Geheimnis um den 32. Monolithen auf die Spur. Währenddessen eskaliert die Lage in Tokyo...
With three days to go before Monolith 32's collapse, Rentaro and Kisara continue tutoring Matsuzaki's Cursed Children, taking them to visit the Flames of Revolution memorial site where they show their affection for Rentaro. Later that night, Rentaro and Kisara investigate the crumbling Monolith 32 and ponder on why it was specifically targeted by the Aldebaran Gastrea, with Kisara deciding to conduct further research on it. The next day the Tokyo Area's population begins evacuating into underground shelters via lottery, and the remaining public's tension against the Cursed Children only escalates further, forcing Rentaro to rescue the blind Cursed Child from an angry mob. Back at the camp, Kisara and Rentaro are left in shock after learning that Monolith 32 was privately commissioned by Kazumitsu Tendo. The next day, Rentaro and Enju horrifically discover that the other Cursed Children had been killed when a bomb was deliberately dropped on the school. This sends Rentaro into a depression and he vents his frustration on Kisara by arguing against the corrupt strata of their society. Suddenly, the winds knock Monolith 32 to the ground a day early, leaving everyone with no time for grief due to the imminent Gastrea invasion.
Alors que la bataille décisive approche, Satomi organise une sortie scolaire à la Flamme du retour avec ses élèves.
Tre giorni prima del crollo del Monolite 32, Rentaro e Kisara continuano a fare da insegnanti alle bambine maledette di Matsuzaki, portandole a visitare il sito commemorativo delle Fiamme della Rivoluzione, dove mostrano il loro affetto per Rentaro.
