Things had been going well for the Gensokyo Railway, the trains ran on time, the extension to Mayohiga was being built, and everyone was busy. Until something happened, the signals had started to change by themselves. At first Nitori thought that this was a mechanical fault and the signals that were affected needed fixing. Then the signal started switching again, sometimes as trains were going by them. While most of the accidents were averted, other things started to get "inverted". Trains started running in reserve, turntables moving in opposite movements, which made the bigger engines late for their trains.
"There is something up going on." said Nitori during a meeting.
"Maybe there's something...down." said Yukari, back to her mysterious self.
"I don't like where this is going." one of the Kappa Valley representatives said.
"Whoever or whatever is doing this needs to stop!" the recent events had been a trigger for Nitori.
"Construction had to stop on the Mayohiga extension!"
"Ask Reimu, she'll know who's been doing this." said the Scarlet Controller.
When Reimu was asked about who was doing this, she groaned.
"Dammit! Seija is at it again!"
"Isn't she the one who had the Miracle Mallet?" asked Nitori.
"Yes." grunted Reimu.
"She also robbed my shrine and I wasn't happy about it."
"Do you think you can find where she is?" asked Nitori.
"Yes, I'll go deal with her."
Reimu went back inside to have a stiff drink before going out and having to deal with Seija Kijin yet again.
