The Galaxy Railways

The Galaxy Railways operate in space, allowing trains to travel between planets. This mode of transportation has its own set of challenges, with crime and terrorism posing threats to passengers and crew. Manabu Yuuki joins the Space Defence Force (SDF), an elite group tasked with protecting the railways and responding to emergency situations. As a member of the SDF, Manabu must learn to navigate the demands of his job and face the challenges that come with it.
