Yukina

Оригінальне ім’я: 侑那

A crew member of the Hayajiro "Koutetsujou". Although calm and reserved, she's very trustworthy, rational and caring, and doesn't hesitate to stand up for herself when necessary. She's also incredibly passionate and skilled at her job - at times putting more experienced drivers to shame whenever they doubt her or disregard her as a mere trainee - as well as physically strong, being able to operate heavy machinery all by herself. Despite frequently bossing him around, she seems to have some degree of affection towards Sukari.
