Plot
A mysterious virus appears during the Industrial Revolution that transforms infected humans into Kabane (かばね) and rapidly spreads. Kabane are aggressive, undead creatures that cannot be defeated unless the glowing golden heart, which is protected by a layer of iron, is pierced, or an important body part (such as the head) is completely severed. However, most melee weapons and the steam-pressure guns used by the bushi (武士) are not very effective against them.
On the island country Hinomoto (日ノ本), people have built fortress-like "stations" to shelter themselves from these creatures. People access the stations and transport wares between them with the help of fortified steam locomotives (駿城).
