## Plot

A mysterious virus appears during the Industrial Revolution that transforms infected humans into Kabane (かばね, "Corpses") 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, "Warriors") 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, hayajirō). 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" (ツラヌキ筒, Tsuranuki Zutsu), 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 (無名, "Nameless"), another Kabaneri who appears to help them, Ikoma and the other survivors of the station board a hayajirō named Kōtetsujō (甲鉄城, lit. 'Iron Fortress') and depart to seek shelter elsewhere, fighting the hordes of kabane along the way.

## Characters
### Ikoma (生駒)

    Voiced by: Tasuku Hatanaka (Japanese); Robbie Daymond (English)
    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.

### Mumei (無名, lit. 'No name')

    Voiced by: Sayaka Senbongi (Japanese); Janice Kawaye (English)
    A mysterious and anonymous girl who boards the hayajiro Kotetsujo and appears at Aragane Station. She is revealed to be a Kabaneri as well as a very strong and agile fighter, capable of killing dozens of Kabane with ease. She became a Kabaneri through a surgical operation as the result of her brainwashing by Biba, making her believe unless she became stronger, she would also end up like her mother. Constant fighting can leave her sleepy and like Ikoma, she requires blood to stop herself from attacking other people. 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.

### Ayame Yomogawa (四方川 菖蒲, Yomogawa Ayame)

    Voiced by: Maaya Uchida (Japanese); Veronica Taylor (English)
    The eldest daughter of the Yomogawa family, which governs Aragane Station. After her father is infected, she becomes the leader of the Aragane survivors.

He is later given a reinforced katana that can pierce a Kabane's heart with ease. Kurusu seems to have feelings for Lady Ayame, as he frequently blushes around her.

### Takumi (逞生)

    Voiced by: Mamoru Miyano (Japanese); Roger Craig Smith (English)
    The Leader of the Hunters (狩方衆, Karikatashū) 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.

### Horobi (滅火)

    Voiced by: Aya Endō (Japanese); Cissy Jones (English)
    A Kabaneri member of the Hunters. She is turned into a Black Fog (黒煙, Kuro Keburi) by Biba in order to destroy the Iwato Station, only for the virus to go out of control and mutate her even more. She only stops at the sight of Biba at which point he callously murders her.

### Uryuu (瓜生)

    The Captain of the Hunters, who serves under Biba Amatori.

### 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.

| On the island country of Hinomoto, the hayajiro Kōtetsujō, an armored train, is attacked by several Kabane, humans transformed into undead creatures by a viral infection, and the bushi defeat them. However, a bushi is bitten, forcing him to commit suicide to avoid becoming a Kabane. At the train's destination, Aragane Station (顕金駅), Ikoma, a steamsmith, is working on a powerful piercing gun to kill the Kabane. The Kōtetsujō arrives at Aragane Station and Ikoma steals some Kabane body parts. Kensho, the leader of the Yomogawa family, excuses Shimon and Mumei, two passengers from the mandatory Kabane inspection who are headed for Kongokaku. Ikoma is detained for insubordination and is secretly visited by Mumei as she is intrigued by his personality and interest in the Kabane. Later, another hayajiro called Fusōjō (扶桑城) approaches the station. The defensive drawbridge is lowered, but as the train exits the tunnel, it's revealed that the Kabane have taken over the train, making it crash through the defending wall, allowing them to attack the station. Ikoma flees to his home, lures a Kabane to the house and kills it with his invention, but is bitten in the process and begins to transform into a Kabane. Using several painful and potentially fatal techniques, Ikoma stops his blood flow enough to keep it from carrying the virus to his brain, reverting to his human form and passing out. Meanwhile, Mumei kills a Kabane using a blade which forms the base of her shoe. ||||||

Meanwhile, survivors of the Kabane attack fight a defensive battle within Aragane Station while seeking an opportunity to escape in the Kōtetsujō. Mumei arrives dressed in battle gear and offers to clear the way so Yukina, the sole remaining engineer and an apprentice, can commander the Kōtetsujō. She leaps into the midst of the Kabane and leads them away, killing several in the process. The remaining citizens then rush to board the train. Meanwhile, Ikoma and Takumi attempt to join the others onboard with his gun. Mumei detects something different about Ikoma and vouches for his boarding the Kōtetsujō. Ayame Yomogawa, Kensho's daughter, produces the special key to start the train's engine while her bodyguard Kurusu takes command, and tells Mumei to defend the train's rear, but she refuses and falls asleep. While fending off a Kabane, Ikoma's infected heart is exposed, and he is forced off the Kōtetsujō. However, the train is stopped by a malfunction of the drawbridge, and the passengers witness Ikoma killing the Kabane. Lecturing the passengers for their distrust, Ikoma manually releases the drawbridge for the train. Despite the bushi's objections, Takumi and Mumei get Ikoma back on the Kōtetsujō as it leaves Aragane Station behind. Before Kurusu can kill him, Mumei intervenes and reveals that she and Ikoma are Kabaneri - beings with an existence between humans and Kabane. ||||||

The Kōtetsujō is headed for Kongokaku, the shōgun's greatest stronghold and Mumei insists on staying onboard. However, the passengers are filled with alarm and distrust because of a lack of food and water, doubt whether they will be admitted into Kongokaku, and presence of the Kabaneri accompanying them. Mumei reveals that she has a mission and needs help from him because she gets exhausted after fighting. She begins training Ikoma personally in preparation for future Kabane attacks. The train has to stop for water and repairs, and the passengers take the opportunity to pray for those who died at Aragane Station. Ikoma tells Mumei that he has vowed to avenge his sister's death at the hands of the Kabane and a green stone tied to his palm which seems to have some effect on the Kabane. Mumei reveals that Kabaneri can only survive by drinking human blood, and later kills a pregnant woman who becomes a Kabane. Meanwhile, Ayame attacks Ikoma, but Ikoma tells her about his vow, appeasing the passengers' fears of the Kabaneri. However, Ikoma becomes delirious from his own need of blood and attacks Ayame. ||||||

To Ayame's dismay, Akoji reroutes the Kōtetsujō for the mountains to provide a shorter route to Kongokaku, in spite of the increased danger posed by the Kabane on the exposed mountain path. Then, Akoji dispatches a chief to get Takumi and fellow steam smiths Kajika and Sukari to the Kōtetsujō's last car with Mumei and Ikoma and detach the car. However, the Kabane, including by a sword wielding Wazatori (a Kabane that has learned combat techniques and is thus much more dangerous), ambushes the Kōtetsujō and kills some of its passengers. Ayame, Kurusu and the bushi hold off the Kabane while the surviving passengers escape to the train's front. Using his sword-wielding skills, Kurusu fights the remaining Kabane inside the train at close quarters. Simultaneously, Mumei, Ikoma and their allies escape from their car and fight the Kabane, but Mumei falls asleep from exhaustion. Kurusu fights the Wazatori but is injured in the process. With Ikoma in need of fresh blood, Ayame slashes her arm and replenishes him with her blood. After Ikoma kills the Wazatori, Ayame leads a cry of "rokkon shōjō!” (六根清浄!) to celebrate their victory.

Ikoma suggest a cautious route to the crane, but Mumei unexpectedly insists on a head-on clash with the Kabane. While Ikoma leads a group of engineers to start the crane, Mumei attacks the nest of Kabane single handed, estimating that she has 90 seconds of energy left. She defeats them, but before the working party can start the crane, even more Kabane appear. The crew retreat and Ikoma starts to lift the debris with the crane while Mumei uses her remaining energy to fight the horde of Kabane.

Ayame and Kurusu with Ikoma hold a meeting with Kuroji of the Federal Forces, General Mogari of the Echigo-Tora-Ohuki and Unmo representing the Unato population. Kuroji plans to use the Narukami, an armored hayajiro with giant cannon mounted on board, to blast the castle while Mogari's men and 200 Unato fighters led by Unmo lead a ground assault. However, Ikoma believes that the Kabane in the castle are being controlled in some way and wants to investigate the castle area first.

Meanwhile, the Narukami reaches the main route to Unato early so Kuroji decides to begin the assault on the castle immediately. Hearing the commotion, Ikoma breaks free from his chains and tries to find Mumei. Meanwhile, Unmo's group are suddenly attacked by Kabane who emerge from the tunnel and attack them, overwhelming the Federal soldiers. Mumei immediately heads into the tunnel, but she finds a series of traps and then encounters a powerful and fast Kazatori. Kuroji orders the cannon to begin firing, but Kageyuki who is now a Kabaneri, fires bullets filled with blood at the cannon, attracting hordes of Kabane who engulf the Narukami. When Kuroji orders the cannon fired again, it explodes, destroying itself and the Kabane who overrun the train, killing all the troops, including Kuroji. In the tunnel, Mumei is wounded and cornered by the kazatori, but at the last minute, Ikoma arrives and kills it. Episode 3 Ikoma saves Mumei and as they embrace, they mysteriously find themselves bathed in a green light and are revived. They are joined by Sukari's crew and advance along the tunnel. Meanwhile, Ayame and Kurusu, assisted by Mogari and his men drive the Kōtetsujō upwards toward the castle. Ikoma's group are fired on by Kageyuki and they see a child encased in a blue light in the Kabane nest. Unmo then tells the group how after Kageyuki became a Kabaneri, his daughter Miyuki was killed trying to save him, so he bit her to make her a Kabane and she has since become the core of a "Black Fog". They realize that they must stop Kageyuki before Unato is completely destroyed. Mumei attacks him, but during the fight, Unmo vainly sacrifices himself to stop Kageyuki giving Mumei renewed conviction, and she fatally shoots Kageyuki. This releases Miyuki who transforms into a Black Fog, emerging from the mountain, cutting a destructive path towards Unato. Ayame orders the Kōtetsujō to leave after Ikoma and Sukari's group return, but the Black Fog catches the train. Desperately, Yukina drives the train at full speed into a dead-end tunnel and fire the train's cannon at the same time, destroying and dissipating the monster. As snow begins to fall, the Kōtetsujō leaves Unato, and the key players share some tender moments together. |||||
