How to Rip a Heart Apart

The infamous pair of young and ruthless excecutives known as Double Black, raised to be a killer tool since they joined the Port Mafia, is sent on a mission, one of the many the two have faced during years of partnership.Nothing seems out of the ordinary, at least not for someone who, like them, is used to perpetrate violence as a way of living.Nothing strange, really, except from the fact that this time their aimed goals do not coincide.Questions of trust are delicate matters, and Chuuya is too often blinded by his complete faith in his colleagues to feel properly detached: after all, he doesn't know his long term partner has been ordered to kill him.What Dazai doesn't know, on the other hand, is that Chuuya is also hiding something from him, a ravenous feeling who could make their joined fate even worse.Aside from everything, they are both convinced of two simple things: there is no way to mend what is beyond repair, and there is no turning back from ripping a heart apart. (Contains spoilers from: Stormbringer [Light Novel]; Fifteen [Light Novel and anime adaptation]; Osamu Dazai and the Dark Era [Light Novel and anime adaptation])
