Your in for a treat
So this one is about trains and i'm making a post now cause its amazing, the show itself is great and enjoyable. So i guess this is remon's recommended show of the season!!!
Nah really you should watch it, even if they have a slight thing or two for really animating those butts but hey they've done a great job so far, so i highly recommend watching it.
To make it clear Aoi is best girl!
