Hi. [[and with a smile, he holds out a colorful hard cover book.]] Here it is. Tomoe-san said it was pretty helpful when she was trying to figure things out, so hopefully it'll be for you as well. It's a kid's book, so they explain a lot of things really simplistically so it shouldn't be too confusing, I hope!

[[Though Tomoe had been from an era that did have electric and trains, but only just barely... Hopefully it would still help.]]
