Original Name: Kōtetsujō no Kabaneri
A mysterious virus appears during the industrial revolution, the infection transforming humans into Kabane and rapidly spreads. Kabane are aggressive, undead creatures that cannot be defeated unless the glowing heart, which is protected by a layer of iron, is pierced. Unfortunately, most melee weapons and the steam-pressure guns used by the Bushi are not very effective against them. On the island country Hinomoto, 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 armored steam locomotives called Hayajiro. One day a Hayajiro hijacked by the Kabane crashes into Aragane station and they overrun the city. A young engineer called Ikoma uses the opportunity to test with success his anti-Kabane weapon, the piercing gun, but is infected in the process, although he manages to resist the virus and become a Kabaneri, a human-Kabane hybrid. Assisted by Mumei, another Kabaneri who appears to help them, Ikoma and the other survivors of the station board the Hayajiro Kotetsujo (Iron Fortress) and depart to seek shelter elsewhere, fighting the hordes of Kabane along the way.
