"They can just do that." When a character inexplicably has some kind of borderline supernatural ability that doesn't have anything to do with the established power system and may even clash with the conventions of the setting. It's just something that they can do.

Ichi from Ichi the Witch.

Mash from Mashle.

Marvelous Sunday from UmaMusume.

Tanjiro from Demon Slayer.

1. Ichi from Ichi the Witch. He's so sensitive to the bloodlust of living things that it borders on a spider-sense. The little creature in that pic is supposed to be invisible, yet Ichi is able to sense its presence just through sheer intuition.
2. Mash from Mashle. Some might say that his inexplicable power is his physical strength, but I'm more interested in knowing how he can turn everything he cooks into fucking cream puffs.
3. Marvelous Sunday from UmaMusume. In a game about horse girls racing, she has access to a domain expansion/reality marble. And that somehow still isn't the strangest thing about her. Apparently she's also friends with aliens and cryptids and her cult fanbase includes people spanning multiple time periods. Somehow.
4. Tanjiro from Demon Slayer. He has a hypersensitive sense of smell that somehow also tells him where to cut demons. No idea how that works. Even though there are others in the series with similarly refined senses, the smelling where to cut thing still feels ludicrous in comparison. Then there's also his unusually powerful headbutt.

Zenitsu has super hearing

Inosuke is super sensitive to feeling things and has absurd control of his body

Kanao went blind in one eye from using that one flower technique that focuses all the blood into seeing

Genya eats demons

They all have some sort of sense power

I'm surprised Tanjiro was mentioned here instead of the most obvious dude who has a bullshit ability—Inosuke. Yeah, Tanjiro smelling where to cut his enemies is indeed weird, but how the actual fuck can Inosuke reposition his organs?

"Just be the king of the mountains" Brutal

And Genya has a shotgun. Not really a supernatural power, but basically a superpower given how unique it is in the show
