I didn’t go looking for Mieruko-chan. Amazon’s Kindle store recommended it to me. My first impression was that it was one more schoolgirl horror manga, the kind you can find anywhere. Then I got to the premise: the heroine sees terrifying things and keeps ignoring them, no matter what. I wondered whether that might suit the Japanese mentality. That is a big generalization, so I’ll stick to what I see around me.

Here is how Mieruko-chan almost didn’t exist. According to the afterword of volume 1, an early idea was a slapstick, violent comedy about twin brothers and twin sisters. The author’s wife said that wasn’t it. A schoolgirl who suddenly sees terrifying things, and does everything she can to pretend she doesn’t, would be the better comedy.

She was right. And reading the series in Japanese, I started to think the ghosts matter as much as the ignoring does. They are not scary the way ghosts usually are. They are familiar.

Rude, Clingy, Greedy: The Ghosts You Already Know

Take the girl on the bus in volume 1. She is a ghost, and her crime is talking loudly. In Japan there is a strong norm of keeping quiet on buses and trains, so a loud passenger is already a small horror before anything supernatural happens.

It is not far from what I see on the train. Often there are people fighting with each other, people who are visibly irritated, people who look dangerous. And almost everyone does the same thing: nothing. They stay indifferent, as if they saw nothing at all.

The series keeps going back to these small nuisances. A scene where Miko, eyes on her phone, joins a line without looking up, and only learns when a friend asks what she is queuing for that it is a line of ghosts. It works as a warning about looking at your phone instead of where you are. A ghost who clings to someone out of plain obsession. In the same volume, a ghost clings to a person who abuses a cat and murmurs abuse right next to their ear, as if it were showing who that person really is.

These ghosts are not strangers from the afterlife. They are the worst version of people we already know, and Miko is the only one who can see it. The rules the book teaches are small ones: watch where you walk, think about the people around you, don’t hurt something weaker than you.

Some of them even make a grim kind of sense. In volume 3, the ghost that has been haunting a cat abuser turns out to be tied to an obsessive mother. Once you know, it feels right: a ghost like that attaches itself to a person like that.

Why she can’t just look away

Seen this way, Miko’s rule is something familiar too. She does what the people on my train do. She notices, she is bothered, and she keeps her eyes straight ahead.

It isn’t only about nuisances. In the line for the office elevator, I might pass someone from my workplace, and it is rare for either of us to say good morning. It is as if we hadn’t logged in until we walk through the office door.

To me, this kind of ignoring is a way of getting by in Japan. And Mieruko-chan seems to show what it costs, too: Miko ignores the ghosts, but she is still exposed to everything around her, and the pent-up gloom of that comes through.

The difference is that a ghost can turn around and look back. In the gym storeroom in volume 2, a huge ghost looms over Miko and a girl who can see only some of the ghosts. The moment it suspects that one of them might see it, it perks up, and Miko’s whole mind goes to a single thought: if this thing finds out, it is over. What these ghosts want is to be noticed. So for Miko, pretending not to see isn’t rudeness or fear. It is her only defense.

That is why the comedy lands. We all know how to ignore someone who is being a nuisance. Mieruko-chan just takes that skill, which is usually a small social habit, and makes it a matter of survival.
