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. LOCKDOWN BLUES It's day two of the Tokyo Lockdown with no end in sight. As Kazuya and his friends look for an exit, they rescue a singer named Haru from demons. She gives them a place to stay for the night, but no explanation as to why the demons are after her.
