@KingHarkinian rather than a home-bound spirit, she was probably haunting an individual object, like a small receipt, or something, and has now successfully passed to haunting Oda himself.
Damn she's smol, also I wasn't expecting a heavy past for Oda like that. It's not a wacky over the top story, but a pretty believable one of things just not going his way. I feel that, it's something everyone gets in various degrees at some point of their life.
