Lenka is frustrated to learn that the Aegis Project has a long, long way to go. In order to complete the project, massive amounts of the natural resource known as Oracle must be harvested from the Aragami. As Lenka stands dumbfounded, Soma kicks him out of the way and tells him, “What we can do is hunt Aragami. That’s all.” The veteran God Eaters, Lindow and Soma, are away when the next assignment comes in, so Sakuya, who has been left in charge, decides to hunt lesser Aragami. But knowing that the bigger the core, the faster the Aegis Project can be completed, Lenka suggests that the mission target large-type Aragami. When Kota and Alisa both agree with Lenka, Sakuya decides to take three rookies on a hunt for the large-type Aragami…Vajra.
