The world is in the midst of an industrial revolution when near-immortal monsters appear and, through infection, turn humans into undead creatures: the Kabane. These monsters' only weakness seems to lie in their hearts, but these are protected by a thick layer of iron, requiring tremendous firepower or physical strength to destroy.
On the island of Hinomoto in the Far East, humans have built stations to protect themselves from these creatures; the transportation of people and goods between these stations takes place with the help of huge steam locomotives called hayajiro. The inventive Ikoma not only helps build these locomotives, he has also developed his own weapon to fight the evil creatures with.
When one day his home, the Aragane station, is overrun by Kabane, he tries to save himself with other survivors on board the Koutetsujou. After being bitten while successfully fending off a Kabane, he decides to sacrifice himself to allow the others to escape. However, he is saved at the last second by the mysterious Mumei, who explains to him what he has become: a hybrid of human and Kabane - a Kabaneri.
"Kabaneri of the Iron Fortress" actually surprised me positively, but that was probably because I wasn't expecting much.
The anime looks nice, just like the fights.
The story is relatively predictable, but the anime is still fun.
But it's mainly something for the eye.
