Kabaneri of the Iron Fortress (Zombie Apocalypse)

Mumei

AGE 12. GENDER Female. Mumei is a girl with short brown hair and reddish-brown eyes. She wears an indigo ribbon tied tightly around her neck, which suppresses the Kabane virus. Removing the ribbon allows her to fully access her Kabaneri abilities. A large scar is on her back. When active, the scar glows a fiery yellow, in the same way a Kabane's body glows. Mumei generally acts much like a child and can sometimes be seen playing with toys. Even when fighting Kabane, Mumei treats any situation as if it were a game. Despite her apparent immaturity, she understands her strength as a means to protect others. Although she is rather detached and even ill-mannered towards others, she appears to take an interest in Ikoma.[2] Mumei also appears to have a soft spot for children. Mumei may also give a sense of terror or eeriness in small situations that don't seem too important to her, which may be a factor from her past, such as when she tells the family that it was supposedly good that they lost their dog to the Kabane, or when she asked one of the women at the time of fix-up and prayers at the Koutetsujou for their blood as if it were nothing to her, but was obviously somewhat of a threat to them. She also tends to express or state quotes that her "brother" may have expressed when she was younger, such as "May karma smile upon him/her."

Ikoma

Ikoma is a bespectacled young man of average height and build. He has mahogany eyes and thick, messy, light blonde-green hair. Ikoma typically wore his golden zigzag glasses, which consisted of a missing lens on the left frame while the lens of the right frame was tinted green. As a child, Ikoma originally wore a striped grey and white kimono. As a teenager, Ikoma commonly wore his steamsmith's uniform, which consisted of a light green hoodie, blue robes, a dark-grey belt, and black sandals, with the majority of his clothing fashioned by red sashes. Kabaneri Form. After Ikoma's transformation into a Kabaneri – a human-Kabane hybrid – his skin takes on a pale grey tint alongside red marks spreading across most of his body. His hair turns a lighter green, his eyes turn red, and a portion of his fringe turns white, hanging over his right eye. To prevent the Kabane virus from spreading to his brain, Ikoma bolts and brands a shoddy harness to his body, encompassing his right shoulder and some of his right torso. He also attaches a tight metal collar around his neck to help keep the virus at bay. In terms of clothing, Ikoma primarily dons a tattered crimson cape along with a brown fingerless glove, which conceals a turquoise pebble tied to his right hand, a cherished memento of Hatsune. Ikoma is described as headstrong, iron-willed, foolhardy, and passionate, which contributes to his strong desire to protect mankind from the Kabane and to avenge the memory of his sister Hatsune. As a child, Ikoma cared greatly for Hatsune, and it was evident that he loved her dearly. After her tragic death at the hands of the Kabane, Ikoma was left emotionally traumatized and remorseful over his cowardice and inability to protect her. Hatsune's death motivated Ikoma to exterminate the Kabane; henceforth, he dedicated his very existence to achieving this goal.

Yukina

GENDER Female. AGE 16. Yukina is a light-skinned girl with a lithe yet muscular physique and strawberry-red hair. Typically aloof and with a rather neutral expression, she is usually seen wearing her engineer's uniform. Yukina is shown to be compassionate towards others' feelings. This is evident when she tried to hide the fact from a boy about his father's fate to protect him. In times of need, she is stern and serious about her job and uses her knowledge of the Koutetsujou to protect everyone. First seen in the Koutetsujou's cabin as an apprentice, she has so far been either assisting with the train's piloting or doing it personally. With minimal interaction with the remaining cast, she seems rather focused on her current duties and the train's repair work to fraternize with anyone, and only speaks to the remaining crew when necessary. While stated to be merely an apprentice, she has shown herself to be competent enough to be the Koutetsujou's primary engineer once the evacuation begins. She also has a well-defined set of muscles, and so one can safely assume she has a fair bit of physical strength.

Kajika

GENDER Female. AGE 15. Kajika is shown wearing standard steam smith clothing. She has brown hair and eyes. She is shown to be friendly and on good terms with the other steam smiths. Kajika states that she wishes to be as brave as Ikoma, implying she doesn't think she is very brave. She is seen protecting three children in Koutetsujou. While they took a shortcut onto the mountain pass, she was thrown in with Takumi in the boiler room where Ikoma and Mumei had been locked in.

Ayame Yomogawa

AGE 17. GENDER Female. Ayame has long, dark blue hair and is shown wearing dresses. She has a flower in her hair, which could be a reference to her name, which means Iris. Ayame has a very mature and soft-spoken personality who is shown to be quite obedient and dependent on Kenshou Yomogawa (Ayame's father), such as when she refused to board the Koutetsujou until her father gave her the signal. As a leader, she cares deeply for her people but is very passive in action and decision-making. However, as the story progresses, Ayame is shown to slowly step into her role as the leader of the group. Ayame was first seen at Argame station with Kenshou Yomogawa (Ayame's father) and his bodyguards when she came to have her father's steam gun repaired. She was surprised when Ikoma asked her where she would be pointing the steam gun. When the Koutetsujou arrived earlier at the station, she was visibly worried when her father informed her that another station might have been overrun by kabanes. When her father ordered the bushi to arrest Ikoma for defending a suspected kabane, she tried to stop him for being unreasonable. Her father dismissed her, explaining that maintaining order is the bushi's duty[2]. After the west gate was breached, her father went to the Koutetsujou while he ordered her to remain and wait for his signal. Still waiting for the signal, she refused to go to the Koutetsujou until Mumei cleared a path for them to follow. Ayame taking off the Master.

Kurusu

Kurusu is constantly seen with a somber, serious countenance and a well-kept appearance, his hair tied in a single short tail and clean-shaven. He wears a white shirt under a light blue jacket. He wears what appears to be a dark blue tailed vest that protects his midsection and holds down his blue shoulder plating. He wears blue vambraces and greaves over white trousers, his boots reinforced with metal at the soles and heels. When not equipped with a steam weapon, he constantly carries his blade at his side. Kurusu takes his job extremely seriously, honoring his profession and social class to the extreme, always ready to lay down his life for the common folk and his liege lord. However, he seems to remain close-minded due to the general deep-rooted fear people hold against the Kabane and the prevalent do-or-die attitude regarding the struggle against them. This extends to the point of remaining distrustful of Mumei and Ikoma even after witnessing both their personal involvement in keeping the Koutetsujou and its passengers safe. However, Kurusu has shown signs of humanity and has shown to eventually change his thoughts regarding the Kabaneri. His humane side is revealed mostly through Ayame, such as when he was flabbergasted when she tried to read what he had written down for his wish during one of the episodes. Kurusu was born in Hinomoto, although his origins are unknown. As a child, he was trained as a Bushi where he grew to become an exceptional warrior with a strong code of honor and duty. Kurusu later traveled to Aragane Station governed under the rule of Lord Kenshou Yomogawa. He faithfully served the Yomogawa family and was appointed as Princess Ayame's personal bodyguard, towards whom he developed a secret affection.
