CCG writes - "Collar X Malice takes place in Shinjuku Tokyo which is under quarantine because a terrorist group called Adonis is systematically judging and murdering “sinners” every month. Because this has been ongoing for several months, the public’s opinion of the police is at an all-time low. It also doesn’t help that the first judgement/murder was a corrupt cop. Until this group is disbanded, citizens are under lockdown and have been issued traceable guns to defend themselves."
Intriguing story, from the sounds of it
