If you are interested in anime and are looking for a particular review, readers, then my article from The Everyman Commentary should be right up your alley:
Nothing to Fear but Fear Itself- Lessons in Courage from Kabaneri of the Iron Fortress
Zombie stories typically follow one of two patterns: the zombies overrun humanity, turning most of the world into a reanimated graveyard or the undead are defeated, but only at great cost. However, a little-known Japanese anime series titled Kabaneri no Koutetsujou, or Kabaneri of the Iron Fortress in English, breaks these patterns. The story is set in Hinomoto – a fictional country analogous to Japan- and the zombies are referreed to as “Kabane” (“undead corpses”). The Kabane cannot be killed by regular means because their hearts are protected by an iron cage, and cutting the head off is the only way to kill them. The monsters are much faster and stronger than average humans though, so in Hinomoto’s nascent Industrial Age, fighting the Kabane in close quarters is futile.
Kabane spread their variant zombie virus through blood transmission through an open wound which will turn ahuman into an undead zombie in less than three days, or through bite which will transform the human into a Kabane within minutes. Thus everyone – civilian, soldier, and noble – carries a suicide charge on their belt that is capable of piercing the iron cage around a Kabane’s heart at close range, but also allows the newly infected to die as humans and not have their bodies come back to live a monstrous “life.”
Due to the Kabane plague, humanity has retreated into fortified cities known as stations and the only safe method of transportation for people and goods across a zombie-infested land is on enormous trains called "hayajiro" (one of which is called "Koutetsujou" or "Iron Fortress") and even they are vulnerable. Those traveling by hayajiro must be inspected for wounds or bites when they enter a station, particularly if the train has just roared through a horde of Kabane. Anyone found with an injury is quarantined for three days, and those who run from inspection are shot.
