"Welcome to the Agency."
The city of Eden has long been guarded by the Eden Government Agency, a group of highly-trained individuals who respond to threats and keep the peace in the technologically-advanced city.
When Yoshihide Sakakibara gets unexpectedly picked up by the Agency, he must learn how to adapt to his new life in peacekeeping, all while threats formed from past traumas, underground gangs and a dangerous element long thought to have been destroyed seek to disrupt the peace of the city.
