Fuku is a relatively polite girl, although she is often stressed about finances and work. She thinks she has to work hard to support her parents because their business isn’t doing very well, which her grandmother tells her only adults should worry about.
She is also convinced that demons don’t exist and refuses to go to bed because her grandmother thinks they are vulnerable to demon attacks at night. However, once Kyojuro Rengoku kills Slasher before her eyes, she rectifies this belief and apologizes to her grandmother for doubting what she said.
