When a fellow Extended showed up in Inui’s office on the run from the Security Bureau with a kidnapped child in tow and asking for help Inui almost throws the guy out. But Inui’s loyalty to a brother Extended makes him take the job. Keeping the child safe won’t be easy, since everyone wants him, from the mob to the megacorporation Berühren, which sends out a special agent who knows exactly how to deal with the Extended.
