Yukina

Yukina (侑那, Yukina), a crew member of Koutetsujou, who transports items across Hinomoto. She is a shy but big-sisterly hard worker who loves her job.

On the second episode when Mumei was asking who could drive the Koutetsujou, Yukina comes forward stating that she is only a trainee.

Mumei asks "What's so hard about moving something along a rail?"

Appearance
Yukina is a light skinned girl with a lithe frame and strawberry red hair. Typically aloof and with a rather neutral expression, she has always been seen in her engineer uniform.

Personality
Though not much has been revealed of her, it seems she tends to keep to herself most of the time. Professional and stern, she seldom starts or even engages in conversation, speaking in single phrases and getting right to the point.

Plot
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 with her current duties and the train's repair work to fraternize with anyone, and only speaks to the remaining crew whenever necessary.

Abilities
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.
