Rail Wars! - Nihon Kokuyuu Tetsudou Kouantai - The Revolver

Takayama Naoto is a second-year student at Kiryu Tetsudou High School who dreams of a quiet, peaceful life. However, his hopes are dashed when he is selected for an internship with the Public Rail Road Security Corps, one of the most dangerous workplaces in Japan. Naoto must now serve on the front lines against an extreme-leftist group that seeks to privatize the nation's railways.

Lacking both training and motivation, Naoto is thrown into a conflict that pits him against violent extremists. As he struggles to survive the escalating "rail wars," he must find the strength to protect the railway system he never wanted to defend.
