第 3 集: Ichiya 探望住院學生，其缺席期間出現巨大 Unknown
2016年7月24日 播出
Some of the students are about to be transferred to a safer location, and Ichiya skips patrol duty to visit one such student in the hospital. In Ichiya's opinion, all the students being transferred are "inept amateurs." Meanwhile, in Ichiya's absence, a colossally huge new type of Unknown appears. (Source: Crunchyroll)
