Admiral Red commands the USR (Undersea Silence Revolution or Underwater Silence Revolution), a secretive organization waging war against human exploitation of the oceans. From his advanced submarine, the UX, he orchestrates assaults on global maritime targets, including ships, ports, and naval forces. These attacks force the creation of the multinational Peace-Keeping Navy (PKN) to oppose him.

He personally directs the USR's campaigns, exemplified by a surprise attack exploiting tactical weaknesses in the PKN's inaugural fleet gathering, inflicting heavy losses. The UX employs conventional torpedoes alongside specialized versions capable of disabling sonar systems. Tactics include vertical anti-ship cluster rockets, noted for impracticality compared to real-world naval strategies.

Contrasting his militant role, Admiral Red is depicted as a family man, married with three pre-teen daughters and an infant son named Makoto. His physical appearance includes facial hair and a ponytail.

His motivations remain ambiguous across official media, lacking explicit backstory, ideological depth beyond opposing ocean exploitation, or character evolution. Scenes of his family life imply humanity but do not influence his actions or decisions within the unresolved plot. The conflict concludes without resolution after two OVA episodes, leaving his ultimate fate and the USR's goals unexplored.
