During breakfast, Kanata is introduced to the other members of the 1121st Platoon; Felicia Heideman, Noel Kannagi and Kureha Suminoya. Kureha shows some hostility towards Kanata, but she is assigned to show her around the fort. When Kureha takes Kanata to see the tank of the squadron is kept, which is in the process of being repaired, Kureha expresses her depression because the military often ignores the squadron’s existence. Later that night, Noel and Kanata claim they saw a ghost in the barracks, so Kanata and Kureha are sent to investigate. They learn the place used to be a school. Kureha laments that their platoon is in the middle of nowhere and is generally ignored. The two are surprised by an owl, the same one that stole Rio’s bell, but with Kureha’s help they manage to capture it. They decide to keep it and name it Shuko.

Everyone prepares for Fiesta des Lumiéres, which starts to bring bad memories for Filicia, whose comrades were killed in a fierce battle. While wandering in the battlefield with a heavily wounded arm, she falls into a tunnel which was well buried under the ruin of the past civilization, where she finds a corpse of a soldier of the old era. In her illusion, the corpse approaches her, apologise for the war they could not win, which makes life vanish from the sea, while on the ground humanity is falling apart. Then Filicia was rescued by someone named Princess Iliya. The girls later send off paper lanterns in the river and Filicia tells Rio her reason for living. Meanwhile, a priest seems to recognize Rio from somewhere.
