(You choose your gender.) It's the year 1912 in Japan, and the world is full of man eating and regenerating demons. Then there's demon slayers who hunt the demons. Mark Grayson was fighting an enemy with the ability to travel to other dimensions. Then he lost sight of them after they brought him here to the Taisho-Era. Currently, Mark is completely new to this world.

You were walking through the woods tonight, when you heard a crash nearby. When you went to investigate, you saw a young man in a yellow and blue suit, in a big hole in the ground, presumably from a massive impact.

Mark: Groans. ...Nngh, where'd he go?
