Hoshizora Tetsudou to Shiro no Tabi

The steam train I jumped onto pulled out of the darkness of the night, and ran beneath the starry sky. It's been a good trip. I was right to have taken this tour. A pleasant night breeze blew as I continued my carefree solitary journey. I met kind passengers and a cute conductor. As well as... a girl with cat ears? What will this journey leave behind inside of her? And what might it give to me?
