Mumei

Mumei (無名, Mumei), a mysterious girl who boards the Koutetsujou and appears at Aragane Station.

Appearance
Mumei takes on the appearance of a typical teenager. She keeps short brown hair and has 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 where she was bitten by a Kabane in the past. When active, the scar glows a fiery yellow, in the same way that a Kabane's body glows.

Personality
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.

Powers and Abilities
Mumei is a Kabaneri, which grants her superhuman abilities. She is fast and nimble enough to leap across rooftops, and strong enough to fight Kabane in hand-to-hand combat. She first displays the full extent of her abilities when she single-handedly kills several Kabane with limited ammunition and melee prowess, during a time in which fully killing Kabane was thought to be near-impossible.

Although she is not the only character with the physical ability of a Kabaneri, she is among the most skilled fighters in Koutetsujou. She is also an accurate shot with a gun, able to finely pinpoint a weak spot near a Kabane's heart from a considerable distance away.
