Right! The castle showed up recently, so we thought we'd come and explore!

So are you a ghost then? Did you die here? Do you need some help to pass on or would you like to stay around? What's being a ghost like? What was the Sengoku period really like? Did you know you're in history books now? Can you leave this place? If you can, you should come take a look at the city! Oh, I'm Tachikoma, by the way!
