Mieruko-chan sticks to two main stories, one in which Niguredou Yuria is finally introduced as a third character who can see ghosts and ghouls—more clearly than the old fortune-teller but less clearly than Miko. As we’ve seen on the margins of past episodes, she’s been watching Miko, convinced she can see what she sees.
The thing is, Mieruko is still committed to not disclosing that she can see them, especially when a much larger and spookier ghoul is in the gym storage room that Yuria can’t even see. Her solution for not discussing it is to use a signature submission move of her favorite wrestler, Badger: a serpent drop. It’s not surprising Yuria thinks Miko is threatening her in the nurse’s office later, but it’s just a bit of miscommunication.
Meanwhile, Miko is now seeing so much that others can’t that sometimes she can’t tell ghouls from humans, as she mistakes a tiny, ancient, but very much still alive granny on some steps. She carries the lady to her house, where her daughter proceeds to thank her by going in the house to grab some manjuu. That’s when a creepy business suit-wearing ghoul approaches Miko and she just wants to leave.
The thing is, the ghoul keeps repeating the same four-digit number, which Miko finally types into her smartphone and shows the old lady. Suddenly, like a switch flipped, the granny, whose daughter said had serious dementia, is lucid again. She uses the code to open her safe, use the comb within her departed husband gave her to put her hair up, and prepares to make some pork miso soup.
The granny invites Miko to join them, but seeing what amounts to a mother-daughter reunion (with the ghoul of the father thanking Miko before shambling off), Miko is eager to get home to her family. She makes sure to text her mom she’s on the way home, and when her mom sends a goofy sticker back, Miko can’t help but smile.
Once again, in a very real and meaningful way, Miko’s ability has allowed her to help improve the lives of others. Even if it wasn’t entirely intentional, she helped that lady home and typed that code into her phone. Yuria may want to be a spiritualist, but Miko seems to already be a kind of saint—an individual performing unexplainable deeds for the betterment of others.
