Plot
The "Tokyo Loop Line Duels" were a system established to assist the reconstruction and development of post-WWII Japan. They were a battle for the main artery of Tokyo, the Yamanote line, as all sides traded blood. After a long stalemate, the threat of conflict looms again with the construction of the new Takanawa Gateway Station. Koinosuke Yasuda, who is in charge of Kanda Station, throws himself into the fray for the survival of his town.
