During a mission after Lindow Amamiya was confirmed to be alive, a Corrosive Hannibal helped Tatsumi's team defeat some Kongous in the area before attacking them. Tatsumi manages to block the Aragami's first hit but was blown away by its follow-up, knocking him to the ground. Before anything else can happen to them, though, the protagonist arrives on time to save them and chase away the Corrosive Hannibal. As it leaves the area, Tatsumi waves his hand in the protagonist's face, wondering why they were staring off into the distance. The Defense Unit has disbanded by the time of God Eater 2 and its members (except Kanon) have left Fenrir.
