WonderCon 2016

All train-fanatic Naoto Takayama has dreamed about is becoming an engineer, but when he passes the entrance exam and gets a trainee position with the JNR, his ambitions are totally derailed. Instead of being in the train's front cab, Naoto's stuck in the security division working with two pretty girls, trigger happy Aoi and kindhearted intelligent Haruka, along with Sho, the squad's other male member. Working together, they either deal with various security issues occurring at any train station-like bomb threats and thieves- or assisting customers or passengers.
