Breaker

(Imaginary, Tokyo, single female protagonist or no female protagonist) (I have not mapped anything, if there are similarities, I will not admit it!!) Wearing an ugly mask made of human skin, a mysterious man who called himself "The Face of Fear" detained more than 200 students in the school, took them as hostages, and occupied the entire university. The person who acted as the negotiator turned out to be a young man who had been sentenced to a severe crime and was imprisoned in a special prison——The young man's name was Kanata. He was a "devil" who not only participated in poison gas terrorist attacks that killed more than 1 million people, but also killed 64 police officers and was sentenced to death. Killing hostages while making unnatural demands, the ferocious <Cage City> criminal and the cold-blooded devil who despises the value of other people's lives are engaged in a fierce battle of wits with a handful of cold sweat on their hands...!
