Kanami and the others arrive at Mokusa's headquarters and meet with Origami Yukari's younger sister, Akane. The girls learn the truth of the Great Disaster of Sagami Bay that occurred 20 years ago from her and Friedman. The truth of that day is vastly different from what the young Toji have been taught in school.
Had Yukari's plan succeeded 
on that day twenty years ago,
لو نجحت خطة يوكاري في
،ذلك اليوم قبل عشرين سنة
Wäre Yukaris Plan vor 20 Jahren
erfolgreich gewesen
Si el plan de Yukari
hubiera tenido éxito hace 20 años
Si el plan de Yukari
hubiera tenido éxito hace 20 años
Il y a 20 ans, si le plan de Yukari
avait fonctionné…
Se il piano di Yukari quel giorno di 20 anni fa 
avesse avuto successo
Se o plano da Yukari fosse
um sucesso há 20 anos,
Если бы двадцать лет назад
план Юкари удался,
