The Starry Sky Train and Shiro's Journey

Noir
CV: Yuuko Oono
A girl our hero runs into on the train "Milky Way".
She has cats ears and a tail, but nothing else about her appearance is unusual.
She's lost her memory and is always spacing out.
Her origins are a mystery, but she seems to cherish the protagonist.

Karuha
CV: Mio Hoshitani
The supposed guide on the Milky Way. Despite looking like a conductor, she doesn't seem to know anything about trains. If something goes wrong, she panics. She's the type who can't do anything without a push from the protagonist.

Neri
CV: Yuu Serizawa
A mysterious girl.
The protagonist feels like he's met her somewhere before...

Hanae
CV: Riko Kohara
A beautiful passenger on the train. She's a heavy smoker, meaning she can't get close to the smoke-hating Noir.

Gibier
CV: Nichika Oomori
A cheerful Swedish passenger with less-than-perfect language skills. Gibier is a nickname; her real name is Jennifer Meniordar.

Takase
CV: Kengo Kawanishi
A man who's always sitting in the back gazing at the stars. He seems detached from reality.
