 Iwakami later commented on this unique production experience in an interview with Anime News Network . He mentioned that Shaft was always pressed for time during the production process and only just managed to complete each episode right before its air time . After the earthquake and tsunami occurred , he stated that much of the staff was rattled by the incident and because of this they were not able to work effectively on episodes 11 and 12 . However , in overcoming this situation , he remarked " a week went by , and two weeks went by , and the staff started saying that they couldn 't stay in shock forever , that they had to keep on going , and then production continued .
