A manga created by the very same one that wrote that legendary Vocaloid song by the same name...
1925
For those of you, like me who have ever wondered what exactly that song was about- this wonderful tale of romance and mystery may be the perfect thing for you.
Or you could also ignore its connection to the song, like me, to keep it "mysterious" and "cryptic" and simply enjoy this manga as a spin-off with its own fun tale.
For Vocaloid fans like myself, this manga is an easy 10/10 giving life to character-less characters and a story just for them.
The jokes are silly, but wholesome and entertaining.
The plot is trivial and whimsical, but enjoyable all the same.
Unfortunately, we may never be able to know the true secret behind the Ghost Train, as the series is on hiatus and will probably never return...
Nevertheless, this was a short, but probably the best read I've ever had.
