Haruka Travels Through Time!! - S9-E12
Continuity mistake: When Jonathan is first speaking with an attendant, the woman looking at a map has a yellow shirt, but in the next shot, she has a pink one. Also, the attendant looking at the track does not have a yellow strip on his hat, but in the next shot, he does. Additionally, there are lights in the station, but in the next shot, there are not.
