Plot
A mysterious virus appears during the Industrial Revolution that transforms infected humans into Kabane 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. Unfortunately, most melee weapons and the steam-pressure guns used by the bushilit. 'warriors' 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 fortified steam locomotives. One day, a hayajirō 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" (ツラヌキ), but is infected in the process, although he manages to resist the virus and become a Kabaneri (かばね人), a human-kabane hybrid. Assisted by Mūmei, another Kabaneri who appears to help them, Ikoma and the other survivors of the station board a hayajirō named Kōtetsujō and depart to seek shelter elsewhere, fighting the hordes of kabane along the way.

Characters

 * Ikoma (生駒)
 * A young man who makes a living as a steamsmith at Aragane Station. He and his good friend Takumi developed a bolt gun–like weapon called a piercing gun in order to defeat the Kabane. He is very intelligent and a great craftsman, even going as far as to invent and create a piercing gun with enough strength to break the metal cage around a Kabane's heart. When Aragane Station is invaded by Kabane, Ikoma is able to successfully test his piercing gun, killing a Kabane with the bullet and destroying the metal cage protecting its heart, but is unfortunately bitten in the process. He is able to prevent the virus from reaching his brain by blocking his carotid arteries, transforming him into a human/Kabane hybrid, a Kabaneri. After becoming a Kabaneri, his fighting prowess increases. He gains incredible strength and endurance, even shrugging off gunfire and being bitten by Kabane multiple times. Ikoma and Mumei often fight alongside each other against many Kabane and work exceedingly well as a duo. Ikoma makes a promise to Mumei to someday turn her back into a human as he failed to do so in his childhood for his sister. Ikoma is the male protagonist of the Kabaneri series.

Her birth name is Hozumi (穂積) and she was named Mumei by Biba when he "saved" her as a child. She and Ikoma often fight Kabane together and make a great duo. She treasures Ikoma's promise to one day turn her back into a human, and over the course of the series, Mumei develops feelings for him. Mumei is the female protagonist of the Kabaneri series.

 * Biba Amatori (天鳥 美馬)
 * The Leader of the Hunters (狩方衆) and the eldest son of the shogun. Charismatic, ruthless and manipulative, he inducted Mumei in his philosophy of strength superiority, where the weak don't deserve to live and should not even have the will to. He greatly resents his father for abandoning him and the 400,000 men he sent to fight on the front lines by essentially starving them of supplies. This made him develop his philosophy, making his purpose from that point to kill his father and show him how weak his fear made him. To do that he intends to destroy the Kongokaku (the shogun's stronghold) using artificially created Kabaneri, and the blue blood he developed, making artificial hybrid colonies when injected with huge destructive power.

 * Kageyuki (影雪)
 * The erstwhile Lord of Unato Station. Five years before the Battle of Unato, he shared a close and loving relationship with his daughter, Miyuki. However, when the station is attacked by the Kabane, he is infected with the virus, but he becomes a Kabaneri instead of a full-fledged Kabane. He is surrounded by soldiers threatening to shoot him; he asks his friend, Unmo, whether he is a man or a Kabane. Miyuki tries to stop the soldiers from shooting her father, only to be mistakenly killed. A devastated and enraged Kageyuki goes on a rampage and brutally murders the soldiers in the room. Unmo escapes, but Kageyuki bites his daughter's corpse, wanting her to come back by any means necessary, turning her into a Nue. The Nue forms a nest around the Unato Castle, keeping Unato trapped in a perennial battle against the Kabane.
