There is a crossing in which humans and their carts and wagons go across, youkai cross it too, but not when Kenta goes by. The crossing is unprotected so engines have to whistle when they approach it. Sometimes no one is there, so some engines don't bother at all, even though its against regulations. Ichihiro was one of those engines, he'd pass by without an issue.
But Eiki Shiki, the local yama, saw him pass the crossing without whistling, despite one else being at the crossing. She waited for the next time Ichihiro would cross by. The engine stopped to let her cross. But Eiki just walked up to his driver and began talking.
"What immoral youkai, to drive this metal...thing without warning others. Its dangerous, you ought to be sent to hell for this!" Eiki said angrily.
"We've been here hundreds of times and never had an accident." the driver explained.
"I think otherwise." She said, writing down 'immorally regular law breaker' on a piece of paper she had kept in her pocket.
Ichihiro went away sadly, his driver now worried for his job and how his afterlife was going to be.
The Scarlet Controller was enjoying some tea and cakes and some O type blood, when the head maid, Sakuya, walked in.
"Excuse me mistress, but you're wanted on the telephone." she said.
"Bother that telephone..." the Scarlet Controller said.
She went and picked the phone, on the other line was Eiki.
"Hello?" said the Scarlet Controller.
"Yes this is she...What?...An engine passed by, didn't warn anyone?...A danger to the railway?...yes...yeah...okay, bye."
"Sakuya, come with me, I need to have a talk with that yama." said the Scarlet Controller.
Ichihiro, Eiki, and the Scarlet Controller met in the terminus in the Human Village.
"I don't understand. Clearly Ichihiro knew what he was doing." said the Scarlet Controller.
"That makes it worse! A vampire that sides with this machine and its two criminals." Eiki said.
"I mean we could build a engine with things that protect other people." the Scarlet Controller suggested.
"I don't think that's a good idea mistress, it'd be inefficient just to build another machine just because the yama's upset." the head maid butted in.
"I'm not upset, I'm doing my job! I decide what's wrong and right, good and evil, moral and immoral. What I witnessed was immoral and a danger to the safety of humans and youkai alike." Eiki was flustered.
"I don't know." said the Scarlet Controller, giving up.
"Why not build a proper railway crossing?" said Ichihiro.
"Yeah why not? You probably didn't build one cause your corrupted, like Reimu!" said the angry yama.
"Fine. I'll talk to Nitori about it." the Scarlet Controller said.
"Good. In the meantime, if Komachi brings in anyone that died at that crossing. I'll take this railway apart!" said Eiki, finally agreeing.
While the crossing was being upgraded, trains were to run at a lower speed. This make some of the other engines upset.
"This slowness is going to make me late!" said Akemi, passing the crossing.
"Kuchikitana yama!" said Hiroto later that day.
The only ones that didn't mind the heavily reduced speed limits were Shiro and Kenta. This left with Ichihiro bringing in supplies to the workers as they built the crossing, this was suggested by Eiki as restitution to what she deemed to be a crime. Ichihiro didn't mind, neither did his crew. After all, it meant that the yama didn't complain and try to lecture him.
