I've been thinking about the Inn skit a lot lately... I know it's just meant to be a spooky scary ghost story with no real plot, but it's actually so interesting when you think about it!
Why do you think Choroe killed Osoma?
She's affectionate towards her at the end, so maybe she just wanted her daughter to remain by her side forever. Did she know she would turn into a ghost? Could it be that Choroe didn't want her to be tainted by the cruel, horrible world outside their inn, so she killed her in a pathetic attempt to "preserve her innocence forever"?
It could very well be the opposite. Maybe she couldn't handle Osoma. She IS an energetic, problematic little girl, after all.
If Choroe is anything like Choromatsu, and we can assume she is because that's who they chose to play her character, then I can easily imagine her losing her mind trying to take care of a kid like Osoma...
What if she did it all in a mindless fit of rage? Osoma died in one of the guest rooms, after all. Did she do something to bother the customers? Was that the straw that finally broke the camel's back? A stern scolding that escalated into a murder... That would actually explain why Osoma goes so far to try and make the guests feel welcome in the inn, despite being a literal ghost. She makes an active effort to behave because last time she didn't, she was killed.
Although, she doesn't seem to hold it against her mother. She has seemingly no resentments towards her whatsoever. I wonder if this means Osoma wasn't even old enough to understand good from evil when she died, and thus doesn't fully understand why being a ghost is a bad thing.
She does acknowledge the fact that Choroe murdered her, but she doesn't really care because she gets to be a carefree little kid forever, and can stay by her mother's side pretty much all the time, who she clearly loves despite what she did to her.
All things considered, they seem to be a normal-ish, wholesome relationship with Choroe now. The years definitely softened her. If anything, the old woman must be relieved to have her by her side, because she'd be completely alone otherwise. They're content with the life they lead, mostly because Osoma never grew up enough to realize there was so much more she could've been if only she was still alive.
On another note, I do have to wonder if Choroe benefits from the haunting somehow... She certainly learned to live with it, and does complain about Osoma scaring customers away, but maybe it's not all negatives:
Customers pay for their stay. Osoma scares them away, accidentally or otherwise, so they leave early, but Choroe gets to keep the money anyways! Plus she can always have a room available when she needs one.
I can't see how that'd be good for the inn's reputation, though. Then again, Choroe killed her own daughter in cold blood and appears to not regret it in the slightest, so I wouldn't expect her reasoning to be completely coherent... She's just a working woman that makes do with her circumstances, yessir.
As for Choroe herself... She didn't get any characterization at all other than being Osoma's murderer, but, if I remember correctly, she's the only one in charge of the inn, right?
In my mind, she's a resilient old lady that carries her family's whole legacy on her back. I wonder if she even got married to begin with. She seems to be completely alone, but she's so old there's also the possibility she simply outlived her husband/partner and the rest of her family...
We could make so much shit up about her... There's so much potential for this story to be so much more than what it is...
