As Keiji ate the daikon and asked his question, there was only silence. Yuki only tilted her head questioningly in response to his question. Keiji has heard tales of possession and it certainly seems like Yuki could be possessed. But...some things about this are different than just being possessed by some ghost or spirit. For example, Yuki seems to be...well, as lucid and proactive in her own life as much as she could be at her old age. Whatever is possessing her is not controlling her against her will. And it doesn't seem like she's aware of any foreign entities in her body. 

Keiji gets the sense that maybe what he needs isn't magical knowledge...but knowledge when it comes to religion. 

After enough silence has passed, Keiji attempts to follow the hardy trio of adventurers with Yuki following behind him...

((Roll me a stealth please.))
