A former public prosecutor, and a former lawyer… Mebuki Akira, who is both talented and good-looking, is a person who loathes three things: violence, blackmail, and coercion so much that he finds them nauseating. In order to help those who cannot help themselves, he manages an office called ‘Mebuki Nego Office’ and, as a negotiator, would take up any case, save for international disputes and in-law issues…
