Hikari & Nozomi

Hikari has outstanding talent for driving trains, and was chosen as an officer along with her younger twin sister Nozomi. However, Hikari is terrible at paperwork and administrative tasks. She follows her whims and does things at her own pace without worrying about what others think, which causes all kinds of incidents. Nozomi has a cheerful and lively personality and doesn't worry about small details. Perhaps because of this, Nozomi often gets into trouble with her older twin sister Hikari. Although she's the type to jump right into anything that looks interesting, she is very diligent when it comes to her responsibility for train operations.
