A budding female-eating train in a developed city, that rumor♡(blood-stained black hatred)

This is Big Star Town. This major city, blessed with the world's finest location and abundant supplies, had achieved growth that could be called the center of the entire world. This town, which had already achieved remarkable economic growth, saw its stock prices skyrocket even further in recent years as it grew, causing the land value in this area to balloon to approximately 1,000 times its original worth. Then rumors of a female-eating train begin to spread throughout this great city.... It is said that the train is dyed crimson with blood, and it has become a topic of discussion online that black hatred is the source of this train. This is... a horror novel in which an ordinary high school girl uncovers the truth behind the incident (lol). I hope I can write it all.... P.S., please also check out the original work "When Older Sister Falls." Actually, this promotion is my main purpose.
