Monk regularly comes for her used bed sheets (which are essentially Furoshikis' corpses) and most probably just revives them
(from the 'scare the flower' chapter)
As to why change sheets so much - well, she's a princess I guess
@Doctor_Malsyn The word used in the raws seems to be more about "being on good terms" or being a "close friend" (unless there's some weird connotations I don't know about), so I'm pretty sure it's the former haha
I like how she didn't need to put any engine in it, or even do any magic on it. As long as the contraption looks like her, it's the ghosts own fears that will animate it to kill..
@taneki Ahh, thank you. So the translators are just using a weird translation of it then. Which makes sense, as they still call the teddy-demons "forehead devils"...
