I'm sorry, but I find it quite hypocritical that the agency members who had to be sent by their boss to find a kidnapped colleague are now acting like such good people, giving the mafia's victim a warm welcome. In fact, the contrast with the mafia scenes is quite telling, where they openly know they won't be protected, but at least among themselves they remain loyal to Akutagawa and are willing to help him even if it means risking their lives. I must remind you that Kunikida did not get on the ship to help Atsushi fight Akutagawa, or to rescue the new member. From then on, we learn more about Kenji, a member of the agency. His personality is extremely innocent... and that's about it.
