Mumei

Mumei whose real name is Hozumi, is the main female protagonist of Kabaneri of the Iron Fortress. A mysterious and anonymous girl whom later reveals herself to be a Kabaneri. She is the adoptive younger sister of Biba Amatori, leader of the Hunters. Upon visiting Aragane Station, she meets Ikoma, a fellow Kabaneri and the two board the Koutetsujou where they proved their allegiance towards Princess Ayame Yomogawa and began their journey towards Kongoukaku. 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 enables her to access her Kabaneri abilities fully. Her back is home to a large scar. When active, the scar glows a fiery yellow, in the same way that 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 though it is 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 interest in Ikoma. Mumei appears to have a soft spot for children as well. Mumei may also give a sense of terror or eeriness when it comes to small situations that doesn't seem too important to her, which may be a factor from her past, like 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 like it was nothing to her, but was obviously a somewhat threat to them. She also tends to express or state quotes that her "brother" may have expressed when she was younger, like "May karma smile upon him/her".
