Earlier on in Mieruko-Chan, there were bickerings among the viewers about the unnecessary fanservice in the show.
The situations keep repeating themselves almost one for one: Miko notices something strange but doesn't really do anything about it, a spirit approaches her and starts questioning whether she sees it they are, apparently, very inquisitive , she maintains her poker face while being terrified on the inside, spirit goes away, Miko moves on with her life until she runs into another one.
And this is a clear example of people like mangaka Tomoki Izumi, knowing the intricacies of a simple plot and using its characters to elevate the story segments intimately, as such seen with the protagonist Miko Yotsuya, with ghosts lurking at every corner that sends shudders on her skin each and every time she encounters them.
