Section chief of the Amaterasu Corporation Peacekeepers Investigations Team. A mumbling, unhealthy-looking man. He habitually speaks through a megaphone to make up for his feeble voice—He constantly requires his megaphone in order to make his quiet voice heard, even within the same room. Seth is arrogant and demanding, he doesn't mind using his power to get what he wants when he wants—still, he's physically weak, so he can't fight.
