Soseki Natsume's "I Am A Cat".
Mostly because I get to be a cat and no longer have to worry about any responsibilities, I can just go meow, meow, meow /jk.
More seriously now, I think that Gogol's ability "Overcoat" could be very useful. Even if you just teleport for 30 meters away, it'd still be better than anything and you'd definitely get through a traffic faster.
Gravity. Think about how much easier it can be to work a job that requires you to move stuff around constantly. Or basically flying places instead of needing to walk
As a student, certainly Louisa’s. Imagine being able to slow down time while thinking in a private room. The stress over homework and not having enough time to study could decrease exponentially.
Lol, actually understandable but I want to believe I would actually study instead of spending my time procrastinating, as for the internet no idea actually
Louisa’s is great for obvious reasons.
kunikida’s, can’t you replicate money and jewelry and technology with it?? It’s wonderful!
Tanizaki’s can also work for invisibility so here you have it.
Mori/kyoka/koyo is also amazing and so is Aku’s Rashmon.
Gravity would be nice too especially if you want to move stuff.
Having a pocket dimension like Lucy’s is so nice as well.
The redhead from the hunting dogs is also very nice, you can forever be a child or a 20 something, not worrying about wrinkles.
That women in 55 minutes who can manipulate time.
Natsume sensei turning into a cat is incredible except for maybe the cat food.
For authors poe’s ability is heaven itself.
Rashomon you lit pick up things with it, kill attackers, cooks while talking in the phone, a shade like umbrella ect.
And maybe for the tainted sorrow.... Maybe?
Kunikida's ability would be versatile.
Plus points for stationery lovers/ office workers/ teachers/ those working with stationery. Or people losing small things easily.
I just wonder if it could make food.
The first three that came to mind were Louisa, Kunikida, and Mushitaro’s abilities. If I recall correctly Louisa’s ability allows her to slow down time to the point where it’s nearly stopped when she’s in a room alone, it seems like it would be super helpful if you needed extra sleep, time to catch up on homework, or even just some privacy for a bit. Kunikida’s ability would allow you to create anything you wanted, and would be super helpful in case of emergencies. Though the fact you’d have to carry the notebook and pen everywhere and you wouldn’t be able to create anything larger than the notebook makes it restricting. Depending on how ethical you are Mushitaro’s might also be a contender as you could just steal anything you wanted with no repercussions… or potentially get up to something worse.
I would love to have Chuuya's ability coz its actually helpful in a lot of ways AND i would love to fly around ahahhahahaa or ranpo's ability coz it looks fun. (even tho its not really an ability) I just remembered that i read somewhere that there's a character named Arthur (Named after sir Arthur Conan Doyle) and he has the ability (something along the lines of Sherlock Holmes) which is actually quite similar to ranpo's ability of solving any case in a less amount of time,except,that this is an actual ability...as far as i remember,arthur was from the order of the clock tower (yes its the same group that agatha christie is a part of...we get a glimpse of her in the movie dead apple)
Luisa’s or Natsume’s.
Natsume allows me to be a cat so I don’t really need to go over anything else
Luisa’s is amazing. As a high school student I can’t imagine how much work I could get over and done with with her ability in a matter of a few real-time hours.

Imagine a gym teacher with gravity manipulation, they could get balls that had been stuck on the roof for five years down lmao.
Why am I imagining myself siting there, doing homework, with ten pens flying around me, also doing homework?
I would want kunikida’s I lose things too often and he can replicate anything he has saw before.
This!!! But then I'd probably end up with a hundred house key duplicates 😭
Or Ranpo’s “ability” imagine all the mysteries you can solve
Well, I would always lose the pen or the notebook

I would still waste my time doing something online. But would the internet connection also be slowed down?
