Maitetsu

Set in Hinomoto, a fictional version of Japan, where railway travel served as the primary form of transport for a long time. Each locomotive was paired with a humanoid control module, so-called Raillord, that aided the train operator. However, many rail lines had been discontinued due to the rising popularity of ‘aerocrafts,’ a safe and convenient aerial mode of transport. As such, their accompanying Raillords also went into a deep sleep. Soutetsu had lost his entire family in a rail accident and was adopted into the Migita household, which runs a shochu brewery in Ohitoyo city. He returned to his hometown to save it from the potential water pollution if they accepted the proposal to build an aerocraft factory nearby. He woke up the Raillord Hachiroku by accident and became her owner. They agreed to help find her lost locomotive for different purposes, with the help of his stepsister Hibiki, the town’s mayor and local railway chief, Paulette, and others.
