A Wonderful Trip on March 7Th

Looking for Star Dome Railway Fanfic?

I would like to read a book similar to "Star Railway: Beginning with Kafka's Adoption". Let's just say that I've been obsessed with Little Rails recently, especially Blade and Kafka's Mom. I'm looking for high-quality fanfics! (It can be used with or without CP. It would be better if CP is a blade)
