Devil Survivor

デビルサバイバー

After demons break through into the human world, Tokyo must be quarantined. Without power and stuck in a supernatural warzone, 17-year-old Kazuya has only one hope: he must use the COMP, a device created by his cousin Naoya capable of summoning and subduing demons, to defeat the invaders and take back the city.
