Akasaka Tunnel is situated at one of the blockades of the Tokyo Lockdown. According to the information gathered by the protagonist, the tunnel is connected to an underground station of the Yamanote Line. When the protagonists come to investigate the rumors, they find that demons have become able to use COMPs of their own, enabling them to multiply effectively. When they stop the demons from using the COMPs, Misaki Izuna and Fushimi appear and point their guns at them, saying that "[they've] found [their] targets".
